CHARGING THE BATTERY PACK  
Initially charging the battery pack after purchase or extended  
storage (greater than 2 months) will not bring the battery pack  
to its normal operating capacity. After repeating the charge/  
discharge cycle two or three times, the operating capacity will  
increase to normal.  
Do not recharge the battery pack if it is already fully charged.  
Doing so may cause the life of the battery pack to shorten or the  
battery pack may be damaged.  
After recharging the battery pack, disconnect it from the charger.  
Charging the battery pack for more than 5 days may reduce the  
battery pack life due to overcharging.  
Note:  
The ambient temperature should be between 41°F and 104°F  
(5°C and 40°C) while charging is in progress. Charging outside  
this range may not fully charge the battery.  
Always switch OFF the transceiver equipped with a battery pack  
before charging. Using the transceiver while charging its battery  
pack will interfere with correct charging.  
The battery pack life is over when its operating time decreases  
even though it is fully and correctly charged. Replace the battery  
pack.

QUIET TALK/ DIGITAL QUIET TALK  
QT (Quiet Talk) and DQT (Digital Quiet Talk) are functions that  
reject signals from undesired parties that are using the same  
channel as you. You will hear audio from the speaker only  
when you receive a signal that contains a tone or code  
matching the one set up on the channel you are using.  
Likewise, when you transmit on a channel set up with QT or  
DQT, the receiving station must have a matching tone or code  
in order to hear your signal.  
You can select a tone or code for each channel. There are 38  
QT tones (01 to 38) and 83 DQT codes (DQT01 to DQT83).  
After changing the QT/ DQT setting, confirm that the other  
members in your group have selected the same tone or code.

SCANNING THE CHANNELS  
You can scan all the channels of the transceiver to search for  
a signal. When the transceiver verifies a signal on a channel,  
it proceeds to check whether or not its QT/ DQT setting  
matches that which is set up on your transceiver, if you have  
set a channel with QT/ DQT. If the QT/ DQT matches, the  
transceiver stops at the channel and opens the squelch so  
you can listen to the call. If the QT/ DQT does not match, the  
call is ignored and scanning continues.  
Before you can use the scan function, ensure that it is  
activated. You can turn the scan function (the ability to  
perform scan) ON or OFF in Setting Mode:

When a signal is detected and the QT/ DQT  
matches, the channel number appears on the  
display and blinks.  
When the signal is no longer present, the  
transceiver waits for 5 seconds before  
scanning continues.  
If a new signal appears before the 5 seconds  
elapse, the transceiver will remain on the  
channel until the new signal is no longer  
present, at which time it will again wait for  
5 seconds before continuing.  
4
To end the scan at any time, press and hold  
the key for 1 second.  
The transceiver returns to the channel you  
were using before you started scanning.

14  
REVERT CHANNEL  
The revert channel is the channel from which you start  
scanning. So, for example, if you are on channel 1 when you  
begin to scan, your revert channel is channel 1.  
During scan, pressing the PTT switch will automatically select  
the transceiver’s revert channel (in the above example,  
channel 1) and you will begin transmitting. However, if you  
are currently paused on another channel after having received  
a signal (in the above example, any channel other than  
channel 1 – such as channel 9), pressing the PTT switch will  
allow you to transmit on that channel, rather than returning to  
the revert channel. Scanning will resume after 5 seconds,  
unless a signal is present on the channel.

15  
MONITORING A CHANNEL  
When no signals are present, the squelch on the transceiver  
automatically mutes the speaker so you will not hear  
background noise. Using the MON key, you can disable the  
squelch to unmute the speaker at any time. This feature is  
useful for a variety of reasons:  
It allows you to confirm the channel activity so that you  
don’t make a call while another party is using the same  
channel.  
It allows you to adjust the volume level without having to  
wait for a call.  
When receiving a call that is intermittent due to a weak  
signal, disabling the squelch will allow you to listen to the  
call without it continuously cutting out.  
To manually deactivate the squelch, press and  
hold the MON key.  
When deactivated, the icon appears on the  
display and the LED lights green.  
To return to normal operation, simply release the  
MON key.

VOICE ACTIVATED CONTROL (VOX)  
Using the VOX feature, you can operate the transceiver  
hands-free. In order to use this feature, however, you must  
use an optional headset; VOX will not function with the built-in  
microphone. For best operation conditions, we recommend  
you use an optional headset with both an ear piece and a  
microphone on a boom that rests in front of your mouth.  
With VOX activated, your voice level will determine when the  
transceiver transmits. Because of this, you must take care  
that the ambient noise around you is not so loud that it causes  
the transceiver to transmit. Due to the automatic switching  
between transmission and reception, we recommend you set  
the VOX gain such that it will not activate transmission when  
in an area with excessive ambient noise.  
VOX GAIN  
To enjoy the VOX function, take the time to properly adjust the  
VOX Gain. This level controls the VOX circuit to detect the  
presence or absence of your voice.

VOX DELAY TIME  
If the transceiver returns to receive mode too quickly after you  
stop speaking, the end of your message may not be  
transmitted. To avoid this, select an appropriate delay time  
that allows your entire message to be transmitted. However,  
do not make the delay overly long.

PRIVACY TALK  
Whereas the Quiet Talk and Digital Quiet Talk functions  
(page 11) allow you to ignore unwanted calls, Privacy Talk  
allows you to hold a conversation in complete privacy. When  
activated, any other party listening in on your channel will be  
unable to understand your conversation. The transceiver  
scrambles your voice so that anybody listening to your  
conversation will not be able to understand what you are  
saying.  
In order for members of your own group to understand your  
call while you are using Privacy Talk, all other members must  
also activate Privacy Talk on their transceivers. This  
scrambles everybody’s voice while transmitting and  
unscrambles the voice message on your own transceiver  
when you receive the message.

TIME-OUT TIMER  
The purpose of the Time-out Timer is to prevent you from  
using a channel for a long time. This function is useful, for  
example, when you accidentally keep the PTT switch pressed.  
Additionally, by limiting the amount of time you can  
continuously transmit, this feature helps you save on battery  
power consumption.  
If you continuously transmit for 3 minutes (default value), the  
transceiver will stop transmitting and a tone will sound. To  
stop the tone, release the PTT switch. You can press the PTT  
switch again to resume transmitting.  
This transceiver is also equipped with a pre-alert tone  
which sounds 10 seconds before the Time-out Timer expires.  
This will allow you time to finish your message before the  
transceiver automatically stops transmitting.

BATTERY SAVE  
This transceiver has been designed to give you the most out  
of your battery power. The battery save function decreases  
the amount of power used when a signal is not being received  
and no operations are being performed.  
While using the transceiver, battery save will automatically  
switch ON after 10 seconds have elapsed with no operations  
or received calls. Operating the transceiver or receiving a call  
will switch this feature OFF until 10 seconds of non-operation  
occurs again.  
You can turn this function ON or OFF:

BATTERY INDICATOR  
When turned ON, the battery indicator on the display lets you  
know approximately how much battery life is remaining. When  
turned OFF, the battery indicator will appear and blink only  
when the battery voltage level is low.  
When the battery voltage becomes too low while transmitting,  
the transceiver stops transmitting and a tone sounds until you  
release the PTT switch. Recharge or replace the battery pack  
at this time.

INCOMING CALL NOTIFICATION TYPE  
Note: To use Incoming Call Notification, you must set up a QT tone  
or a DQT code (page 11).  
Incoming Call Notification is used to inform you of when a call  
is being received. You can set this function to notify you via a  
tone or through vibrating. When vibration is activated (either  
with the vibration only setting or the vibration and tone  
setting), the icon appears on the display.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
28  
When set to notify you via a tone only (setting 1), the tone  
is emitted when a busy signal is received and the  
QT/ DQT signalling matches. The tone will sound for  
15 seconds before turning off. While the tone sounds, you  
will not hear any audio from the speaker. To turn the tone  
off and listen to the received call, press any key. After the  
call is finished, the transceiver will wait for 10 seconds  
before resetting the Incoming Call Notification. If you  
receive a new call within those 10 seconds, the tone will  
not sound. If no call is received within 10 seconds,  
Incoming Call Notification will reset so that the next time a  
call is received, the tone will sound again.  
When set to notify you via vibration only (setting 2), the  
transceiver vibrates when a busy signal is received and  
the QT/ DQT signalling matches. Audio can be heard from  
the speaker while the transceiver vibrates. To stop the  
15 second vibrator, press any key. After the call is  
finished, the transceiver will wait for 10 seconds before  
resetting the Incoming Call Notification.  
When set to notify you via both a tone and through  
vibration (setting 3), the tone is emitted and the transceiver  
vibrates when a busy signal is received and the QT/ DQT  
signalling matches. As with a tone only, you will not hear  
audio from the speaker until the tone is stopped by  
pressing a key or the 15 second tone stops. After the call  
is finished, the transceiver will wait for 10 seconds before  
resetting the Incoming Call Notification.

SIMPLEX/ SEMI-DUPLEX OPERATION  
Simplex operation is simply transmitting and receiving between  
two parties. This is how you normally operate the transceiver.  
However, this transceiver is also capable of using semi-duplex  
operation. In semi-duplex operation, you are able to access a  
repeater, in order to transmit over longer distances. This can  
be useful when a party member is out of range of normal  
transmission. In order to use semi-duplex operation, a repeater  
must be available in the area. Refer to the channel frequency  
tables on pages 41 and 42 for the receive and transmit  
frequencies when using simplex or semi-duplex operation.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
32  
Unless you are familiar with the use of repeaters, and are  
aware of repeaters near your location, we recommend you do  
not use semi-duplex operation; use only simplex operation,  
the default frequency bank of this transceiver. There are two  
separate “banks” of frequencies stored in the transceiver (as  
listed on pages 41 and 42). Frequency Bank A stores those  
frequencies used for simplex operation and Frequency Bank B  
stores those frequencies used for semi-duplex operation.  
To switch the bank between simplex (A) and semi-duplex (B)  
frequencies:

SAFETY INFORMATION:  
Your wireless hand-held portable transceiver has been designed using a  
low power transmitter.  
When the PTT switch is pressed, the transceiver generates radio  
frequency (RF) electromagnetic energy (EME).  
This transceiver is designed to comply with the FCC Report and Order  
FCC 96-326 (August, 1996).  
• Do not transmit for more than 50% of the total operating time.

FCC RF exposure compliance requirements. Transmission occurs  
while you are pressing the PTT switch and is confirmed by the LED  
that lights red while transmitting.  
To transmit, speak into the microphone in your normal voice while  
holding the transceiver upright and keep the antenna at least  
2 inches (5 cm) from your head and body.  
• When using a headset, ensure that the antenna is at least 2 inches  
(5 cm) away from your body whenever you are transmitting.  
• Use only KENWOOD genuine accessories. Unauthorized  
modifications, or attachments may damage the transceiver and  
violate FCC rules and regulations.
