connects to the negative (–) terminal.  
DC POWER CABLE CONNECTION  
1
Locate the power input connector as close to the transceiver as  
possible.  
•
Use the full length of the cable without cutting off excess  
even if the cable is longer than required. In particular,  
never remove the fuse holders from the cable.  
MOBILE OPERATION  
Red  
The vehicle battery must have a nominal rating of 12 V.  
Never connect the transceiver to a 24 V battery. Be sure  
to use a 12 V vehicle battery that has sufficient current  
capacity. If the current to the transceiver is insufficient,  
the display may darken during transmission, or transmit  
output power may drop excessively.  
Black  
Fuse holder  
5 Reconnect any wiring removed from the negative  
terminal.  
1 Route the DC power cable supplied with the  
transceiver directly to the vehicle’s battery terminals  
using the shortest path from the transceiver.  
6 Connect the DC power cable to the transceiver’s  
power supply connector.  
•
Press the connectors firmly together until the locking tab  
clicks.  
•
If using a noise filter, it should be installed with an  
insulator to prevent it from touching metal on the vehicle.  
•
We recommend you do not use the cigarette lighter  
socket as some cigarette lighter sockets introduce an  
unacceptable voltage drop.  
Fuse holder  
•
The entire length of the cable must be dressed so it is  
isolated from heat, moisture, and the engine secondary  
(high voltage) ignition system/ cables.  
2 After the cable is in place, wrap heat-resistant tape  
around the fuse holder to protect it from moisture and  
tie down the full run of cable.  
3 To prevent the risk of short circuits, disconnect other  
wiring from the negative (–) battery terminal before  
connecting the transceiver.

REPLACING FUSES  
ANTENNA CONNECTION  
If the fuse blows, determine the cause, then correct the  
problem. After the problem is resolved, replace the fuse.  
If newly installed fuses continue to blow, disconnect  
the power cable and contact your authorized Kenwood  
dealer or an authorized Kenwood service center for  
assistance.  
Before operating, install an efficient, well-tuned antenna.  
The success of your installation will depend largely on  
the type of antenna and its correct installation. The  
transceiver can give excellent results if the antenna  
system and its installation are given careful attention.  
1
Use a 50 Ω impedance antenna and low-loss coaxial feed  
line that has a characteristic impedance of 50 Ω, to match  
the transceiver input impedance. Coupling the antenna  
to the transceiver via feed lines having an impedance  
other than 50 Ω reduces the efficiency of the antenna  
system and can cause interference to nearby broadcast  
television receivers, radio receivers, and other electronic  
equipment.  
Note: E market models use an N-type antenna connector while  
other models use an M-type (SO-239) connector.

Transmitting without first connecting an antenna or other  
matched load may damage the transceiver. Always connect the  
antenna to the transceiver before transmitting.  
All fixed stations should be equipped with a lightning arrester to  
reduce the risk of fire, electric shock, and transceiver damage.  
Only use fuses of the specified type and rating; otherwise the  
transceiver could be damaged.  
Antenna connector  
Note: If you use the transceiver for a long period when the vehicle  
battery is not fully charged, or when the engine is OFF, the battery  
may become discharged, and will not have sufficient reserves to start  
the vehicle. Avoid using the transceiver under these conditions.

OPERATING THROUGH REPEATERS  
Repeaters, which are often installed and maintained  
OFFSET PROGRAMMING FLOW  
by radio clubs, are usually located on mountain tops  
or other elevated locations. They generally operate at  
higher ERP (Effective Radiated Power) than a typical  
station. This combination of elevation and high ERP  
allows communications over much greater distances than  
communicating without using repeaters.  
1
Select a receive frequency.  
Select an offset direction.  
2
3
Most repeaters use a receive and transmit frequency pair  
with a standard or non-standard offset (odd-split).  
In addition, some repeaters must receive a tone from  
the transceiver to be accessed. For details, consult your  
local repeater reference.  
Select an offset frequency  
(only when programming odd-split  
repeater frequencies).

Activate the Tone function  
(if necessary).

5 Select a tone frequency  
(if necessary).  
If you store all the above data in a Memory Channel, you  
will not need to reprogram the parameters every time.

REVERSE FUNCTION  
◆
◆
◆
◆
You can turn the Reverse function ON when you are operating in  
Simplex Mode. However, it does not change the Transmission/  
Reception frequencies.  
The reverse function exchanges a separate reception  
and transmission frequency. So, while using a repeater,  
you can manually check the strength of a signal that you  
receive directly from the other station. If the station’s  
signal is strong, both stations should move to a simplex  
frequency and free up the repeater.  
If pressing [REV] places the reception frequency outside the  
allowable range, an error tone sounds and the function does not  
operate.  
If pressing [REV] places the transmission frequency outside the  
allowable range, pressing Mic [PTT] causes an error tone to  
sound and transmission is inhibited.  
You cannot switch Reverse ON or OFF while transmitting.  
AUTOMATIC SIMPLEX CHECK (ASC)  
144.725 MHz

While using a repeater, the ASC function periodically  
checks the strength of the signal you are receiving from

PROGRAM SCAN  
When you are operating the transceiver in VFO Mode,  
3 types of scanning are available: Band Scan, Program  
Scan, and MHz Scan.  
You can limit the scanning frequency range. There are  
3 memory channel pairs (L0/U0 ~ L2/U2) available for  
specifying the start and end frequencies. Program  
Scan monitors the range between the start and end  
frequencies that you have stored in these Memory  
Channels. Before performing Program Scan, store the  
Program Scan frequency range to one of the Memory  
Channel pairs (L0/U0 ~ L2/U2).  
BAND SCAN  
The transceiver scans the entire band of the frequency you  
selected. For example, if you are operating and receiving  
at 144.525 MHz, it scans all the frequencies available for  
the VHF band. (Refer to receiver VFO frequency range  
in the specifications {page 72}.) When the current VFO  
receive frequency is outside the Program Scan frequency  
range {below}, the transceiver scans the entire frequency  
range available for the current VFO.

SELECTIVE CALL  
Note: CTCSS and DCS do not cause your conversation to be  
private or scrambled. It only relieves you from listening to unwanted  
conversations.  
CTCSS AND DCS  
You may sometimes want to hear calls from only specific  
persons or groups. In this case, use Selective Call. This  
transceiver is equipped with CTCSS (Continuous Tone  
Coded Squelch System) and DCS (Digital Coded Squelch).  
These Selective Calls allow you to ignore (not hear)  
unwanted calls from other persons who are using the same  
frequency. The transceiver unmutes only when it receives a  
signal having the same CTCSS tone or DCS code.  
CTCSS  
A CTCSS tone is a sub-audible tone and is selectable  
from among the 42 tone frequencies listed in the table  
on page 47. The list includes 37 EIA standard tones and  
5 non-standard tones.  
To activate CTCSS, press [F], [CALL].

DUAL TONE MULTI-FREQUENCY (DTMF) FUNCTIONS  
•
When DTMF TX Hold is activated {page 51}, you do  
not need to continuously press Mic [PTT] to remain  
in transmission mode. However, transmission mode  
is retained for only 2 seconds after pressing a key, so  
if the next key is not pressed within this time limit, the  
transceiver stops transmitting.

Memory Channels. You can store a DTMF number (16  
digits max.) in each of these channels to recall later for  
speed dialing.  
Many repeaters in the U.S.A. and Canada offer a service  
called Autopatch. You can access the public telephone  
network via such a repeater by sending DTMF tones. For  
further information, consult your local repeater reference.
