1.1.1 System Highlights  
Voice Mail Features  
A Voice Processing System (VPS) can be connected to the PBX to provide Voice Mail (VM) and Automated  
Attendant (AA) services. A Panasonic VPS which supports DPT (Digital) Integration can be connected to  
the PBX effortlessly and with minimal setup required. Conventional DTMF (analog) voice mail systems,  
including those from other manufacturers, are also supported.  
Paralleled Telephone Features  
By connecting telephones in parallel, you can increase the number of telephones connected to the PBX  
without adding additional extension cards.  
An SLT can be connected to an APT which is connected to a Hybrid Port of the PBX. The SLT shares the  
same extension number with the APT.  
Portable Station (PS) Features  
A Panasonic PS can be used in place of an APT to provide wireless access to PBX features and call  
handling. When in Wireless XDP Parallel Mode, a PS can share an extension number with a wired  
telephone, allowing extension users to use their PSs when they are away from their desks to answer or make  
calls as if they were using their wired telephones.

Safety Installation Instructions  
When installing telephone wiring, basic safety precautions should always be followed to reduce the risk of  
fire, electric shock and injury to persons, including the following:  
1. Never install telephone wiring during a lightning storm.  
2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.  
3. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected  
at the network interface.  
4. Use caution when installing or modifying telephone lines.  
Installation Precautions  
This PBX is designed for wall mounting only, and should be installed in a location where it is accessible for  
inspections and maintenance.  
To prevent malfunction, noise, or discoloration, avoid installing the system in the following locations:  
1. In direct sunlight and hot, cold, or humid places. (Temperature range: 0 °C to 40 °C [32 °F to 104 °F])  
2. Areas where sulfuric gases may be present, such as near thermal springs.  
3. Areas where shocks or vibrations are frequent or strong.  
4. High-dust areas, or places the system may come into contact with water or oil.  
5. Near devices that generate high frequencies, such as sewing machines or electric welders.  
6. On or near computers, telexes, or other office equipment, as well as microwave ovens or air  
conditioners. (It is preferable not to install the system in the same room as the above equipment.)  
7. Within 1.8 m (6 ft) of radios and televisions. (Both the PBX and PTs should be at least 1.8 m [6ft] away  
from such devices.)  
8. Locations where other objects will obstruct the area around the PBX. Be especially careful to leave at  
least 20 cm (8 in) of space above and 10 cm (4 in) to the sides of the PBX for ventilation.  
9. Do not stack up the optional service cards. To avoid damage to the optional service cards, always use  
the extension bolts.  
Wiring Precautions  
Be sure to follow these instructions when wiring the unit:  
1. Do not run unshielded telephone cables near AC power cables, computer cables, AC power sources,  
etc. When running cables near other noise-generating devices or cables, use shielded telephone  
cables or shield the telephone cables with metal tubing.  
2. If cables are run on the floor, use protectors to prevent the cables from being stepped on. Avoid running  
cables under carpets.  
3. Avoid using the same AC outlet for computers, telexes, and other office equipment, as noise generated  
by such equipment may hamper system performance or interrupt the system.

Voice Processing Systems, etc.  
5. Unplug the system from its power source when wiring, and plug the system back in only after all wiring  
is completed.  
6. Mis-wiring may cause the PBX to operate improperly. Refer to Section 2 "Installation" when wiring the  
system.  
7. If an extension does not operate properly, disconnect the telephone from the extension line and connect  
it again, or turn off the PBX using power switch then turn it on again.  
8. For safety purposes this unit is equipped with a grounded plug. If you do not have a grounded outlet,  
please have one installed. Do not bypass this safety feature by tampering with the plug.  
9. Use twisted pair cable for CO line connection.  
10. CO lines should be installed with surge protectors. For details, refer to "2.2.10 Surge Protector  
11. To assure good quality telephone connection, it is recommended new and modifications to existing  
installation of customer premise wiring shall use solid twisted pair copper conductors with minimum 24  
gauge that comply with the electrical specifications for Category 3 wiring as detailed in ANSI/EIA/TIA-  
570A Building Wiring Standards.

2.2.5 Frame Ground Connection  
IMPORTANT  
Connect the frame of the PBX to ground.  
1. Loosen the screw.  
Screw  
2. Insert a grounding wire (user-supplied)*.  
3. Tighten the screw.  
4. Connect the grounding wire to ground.  
Grounding  
wire  
To ground  
* For grounding wire, green-and-yellow insulation is required, and the cross-sectional area of the  
conductor must be more than 0.75 mm2 or 18 AWG.  
Be sure to comply with applicable local regulations (e.g., law, guidelines).  
Proper grounding (connection to ground) is very important to protect the PBX from the bad effects of  
external noise or to reduce the risk to the user of electrocution in the case of a lightning strike.  
The ground wire of the AC cable has an effect against external noise and lightning strikes, but it may  
not be enough to protect the PBX. A permanent connection between ground and the ground terminal  
of the PBX must be made.  
In most of the continental United States, the ground provided by the "Third wire ground" at the commercial  
power outlet will be satisfactory. However, in a small percentage of cases this ground may be installed  
incorrectly. Therefore, the following test procedure should be performed.  
Test Procedure  
1. Obtain a suitable voltmeter and set it for a possible reading of up to 250 V AC.  
2. Connect the meter probes between the 2 main AC voltage points on the wall outlet. The reading  
obtained should be 108 V AC to 132 V AC.  
3. Move one of the meter probes to the 3rd prong terminal (GND).  
Either the same reading or a reading of 0 volt should be obtained.  
4. If a reading of 0 volt at one terminal and a reading of 108 V AC to 132 V AC at the other terminal  
is not obtained, the outlet is not properly grounded.  
This condition should be corrected by a qualified electrician (per article 250 of the National  
Electrical Code).  
5. If a reading of 0 volt at one terminal and a reading of 108 V AC to 132 V AC at the other terminal  
is obtained, then set the meter to the "OHMS/RX1" scale, place one probe at the GND Terminal  
and the other probe at the terminal which gave a reading of 0 volt.  
A reading of less than 1 ohm should be obtained. If the reading is not obtained, the outlet is not  
adequately grounded. See qualified electrician.

2.2.10 Surge Protector Installation  
Overview  
A massive electrical surge can be caused if lightning strikes a telephone cable 10 m (33 ft) above ground,  
or if a telephone line comes into contact with a power line. A surge protector is a device that is connected  
to a CO line to prevent potentially dangerous electrical surges from entering the building via the CO line and  
damaging the PBX and connected equipment.  
To protect the system from electrical surges, we strongly recommend connecting the system to a surge  
protector that meets the following specifications:  
Surge arrestor type: 3-electrode arrestor  
DC spark-over voltage: 230 V  
Maximum peak current: at least 10 kA  
Additionally, proper grounding is very important for the protection of the system (refer to "2.2.5 Frame  
Many countries/areas have regulations requiring surge protection. Be sure to comply with all applicable  
laws, regulations, and guidelines.

2.2 Installation of the PBX  
1. Connect the ground rod to the surge protector using a grounding wire with a cross-sectional area of at  
least 1.3 mm2.  
2. Bury the ground rod near the protector. The grounding wire should be as short as possible.  
3. The grounding wire should run straight to the ground rod. Do not run the wire around other objects.  
4. Bury the ground rod at least 50 cm (20 in) underground.  
Notes  
The above figures are recommendations only.  
The length of ground rod and the required depth depend on the composition of the soil.

2.7.2 Procedure Overview  
When connecting the wireless system, use extreme care to conduct a site survey. Inadvertent site survey  
can result in poor service area, frequent noise, and disconnection of calls.  
1. Investigate the installation site  
Refer to "2.7.3 Site Planning".  
a. Obtain the map of the CS installation site.  
b. Consider the service area demanded by the user on the map.  
c. Plan the locations of each CS, taking account of distance, building materials and etc.  
2. Prepare the CS for site survey  
a. Assign a CS number to each CS by setting the DIP switches on the back of the CS.  
b. Supply electricity to each CS using an AC adaptor or a battery box.  
c. Install each CS temporarily as planned.  
Notes  
Install at least 2 m (6 ft 7 in) above the floor.  
Keep the antennas in the upright position.  
3. Conduct the site survey  
Refer to "2.7.5 Site Survey".  
a. Test the radio signal strength using the PS.  
Confirm that the radio signal strength level is "12" near the CS.

2.7.3 Site Planning  
Choosing the best site for the CS requires careful planning and testing of essential areas. The best location  
may not always be convenient for installation. Read the following information before installing the unit.  
Understanding the Radio Waves  
Characteristics of Radio Waves  
The transmission of radio waves and the CS coverage area depend on the structure and materials of the  
building.  
Office equipment, such as computers and fax machines, can interfere with radio waves. Such equipment  
may create noise or interfere with the performance of the PS.  
The illustration below shows the special transmitting patterns of radio waves.  
1. Radio waves are reflected by objects such as those made of metal.  
2. Radio waves are diffracted by objects such as metallic columns.  
3. Radio waves penetrate objects such as those made of glass.  
1. Reflection  
CS  
Column  
2. Diffraction  
3. Penetration  
Relationships Between Radio Waves and Building Structure and Materials  
The CS coverage area is affected more by the building materials and their thickness than the number  
of obstacles.  
Radio waves tend to be reflected or diffracted by conductive objects and rarely penetrate them.  
Radio waves tend to penetrate insulated objects and are rarely reflected by them.  
Radio waves penetrate thin objects more than thick objects.  
The table below shows the transmission tendency of radio waves when they reach objects made from  
various materials.

Site Survey Preparation  
1. Obtain the map and investigate the installation site.  
a. Check the obstacles (e.g., shelves, columns, and partitions).  
b. Check the materials of the structures (e.g., metal, concrete, and plywood).  
c. Check the layout and dimensions of the room, corridor, etc.  
d. Write down the above information to the map.  
2. Examine the service area demanded by the user on the map, referring to the following example.  
a. Draw the coverage area around a CS. Extend the coverage area to 30 to 60 meters (98 to 197 feet)  
in one direction, depending on the materials of the building structures and obstacles in the  
installation site. Note that a CS cannot be installed outside a building.  
b. If one CS cannot cover the entire service area, install additional CSs as required. Overlap the  
coverage areas of adjacent CSs.  
Where CS coverage areas overlap, the PS will start call handover to the next CS if the signal from  
74  
Installation Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2.7 Connection of 2.4 GHz Portable Stations  
one CS becomes weak. However, if a PS moves away from a CS and there are no CSs available  
for handover, the PS may go out of range and the call could be lost.  
If the signal from the CS fades, due to the structure of the building, there may be some handover  
delay. The user will hear a range warning before handover in this case. This also applies in the case  
of interference from 2.4 GHz apparatus.  
Example: Installing in a Room Separated by Walls  
Things to take note of:  
The room is separated by walls.  
The room is surrounded by concrete walls.  
CS installation plan:  
The coverage area of each CS will not extend as far as when there is no obstacle, because the  
radio signals will be weakened by separating walls. Therefore, you will need 4 CSs to cover the  
entire room.

Setting the Personal Identification Number (PIN) for PS Registration  
To prevent registering the PS to a wrong PBX, a PIN for PS registration can be set to the PBX. Before  
registering the PS to the PBX, register the PIN set to the PBX into the PS. By doing so, the PS will only be  
registered to the PBX with the matching PIN.  
Notes  
By default, the PIN for PS registration is "1234" for both the PBX and PS. Therefore, the PS can  
be registered to the PBX without setting the PIN.  
The PIN for PS registration will only be used when registering the PS to the PBX. Therefore, even  
when there is more than 1 PBX with the same PIN near the PS, the PS will not be linked to a  
different PBX during normal operation after registration.

After connecting the PBX and the external modem, set the power switch of the external modem to "ON",  
then the external modem will be initialized with the default values.  
The following AT command settings may be required for the modem:  
The Data Terminal Ready (DTR) signal should be ignored.  
The Data Terminal Equipment (DTE)/Modem flow control should be turned off.  
The data compression should be disabled.  
Error Correction is not necessary.  
Notes  
Use an RS-232C straight cable for connection between the PBX and external modem.  
An AT command (for initialization, enabling automatic answer, etc.) can only be programmed by  
KX-TAW848 Maintenance Console. "AT&F0Q0E0V1S0=1X0&D0" is stored as the default value.  
For more information about the AT command, refer to the external modem's instructions.

3.3.1 Installing and Starting the KX-TAW848 Maintenance  
Console  
System Requirements  
Operating System  
Microsoft® Windows® 98 SE, Windows Me, Windows 2000, or Windows XP  
Hardware  
CPU: Intel® Pentium® 133 MHz or better microprocessor  
RAM: at least 64 megabytes (MB) of free RAM (128 MB recommended)  
HDD: at least 100 MB of hard disc space  
Password Security  
Warning to the Administrator or Installer regarding the system password  
1. Please provide all system passwords to the customer.  
2. To avoid unauthorized access and possible abuse of the PBX, keep the passwords secret, and  
inform the customer of the importance of the passwords, and the possible dangers if they become  
known to others.  
3. The PBX has default passwords preset. For security, change these passwords the first time that  
you program the PBX.  
4. Change the passwords periodically.  
5. It is strongly recommended that passwords of 10 numbers or characters be used for maximum  
protection against unauthorized access. For a list of numbers and characters that can be used in  
system passwords, refer to "3.1.3 Entering Characters" in the Feature Guide.  
6. If a system password is forgotten, it can be found by loading a backup of the system data into a  
PC, and checking the password using the KX-TAW848 Maintenance Console software. If you do  
not have a backup of the system data, you must reset the PBX to its factory defaults and reprogram  
it. Therefore, we strongly recommend maintaining a backup of the system data. For more  
information on how to back up the system data, refer to the on-line help of the Maintenance  
Console.  
However, as system passwords can be extracted from backup copies of the system data file, do  
not allow unauthorized access to these files.

3.3 Installation of the PC Programming Software  
Installing the KX-TAW848 Maintenance Console  
Notes  
Make sure to install and use the KX-TAW848 Maintenance Console for MPR version 2.0.  
To install or uninstall the software into Windows 2000 Professional or Windows XP Professional,  
the user must be grouped either of "Administrators" or "Power Users".  
When the PBX is first connected to the PC via USB, a wizard should appear and ask you to select  
the appropriate USB driver. Browse for and select the KX-TDA USB driver, which is copied to the  
local drive during installation.  
1. Copy the KX-TAW848 Maintenance Console setup file  
to a local drive on the PC. (Its icon is shown here, on  
the left.)  
2. Double-click the setup file to run the installer.  
3. Follow the on-screen instructions provided by the  
installation wizard.  
Starting the KX-TAW848 Maintenance Console and Assigning the Basic  
Items (Quick Setup)  
When you start the KX-TAW848 Maintenance Console with the Installer Level Programmer Code and  
connect to the PBX for the first time after initialization (with the factory default setting), Quick Setup will  
launch automatically. During Quick Setup, you will setup the following basic items:  
Date and Time of the PBX. The date and time set on the PC will be used.  
System Password for installer for PC programming.  
Operator extension numbers. Operator extensions for all time modes (day/lunch/break/night) can  
be assigned.  
Flexible Numbering type to pattern 1 or pattern 2. If pattern 1 (with ) is selected, " " must prefix  
all feature numbers (except access numbers) when an extension user wants to use a feature.  
Operator call and Idle Line Access/ARS numbers (0 or 9). The feature numbers for operator call  
and Idle Line Access/ARS can be selected.  
Remote Maintenance Dial Number. Enter the complete telephone number of the PBX (including  
the country code). When necessary, this number will be used to access the PBX from a remote  
location for maintenance purposes.

7. The program menu appears. You may now begin  
programming the PBX.  
Notes  
During long programming sessions, it is highly recommended that you periodically save the system  
data to the SD Memory Card. If the PBX suffers a sudden power failure or if the system is reset for  
some reason and all system data is lost, it can be restored from the SD Memory Card.  
To save the system data to the SD Memory Card, either click the "SD Memory Backup" icon, or  
exit KX-TAW848 Maintenance Console and click "Yes" to save when prompted.  
The PC will not perform any shutdown operation, or enter the power-saving system standby mode  
while the KX-TAW848 Maintenance Console is connected to the PBX. To perform either of the  
operations above, first close the connection to the PBX.  
CAUTION  
Do not remove the SD Memory Card while power is supplied to the PBX. Doing so may cause the PBX  
to fail to start when you try to restart the system.
