•
•
Do not place the transceiver in excessively dusty,  
humid, or wet areas, nor on unstable surfaces.  
Increase the separation between the equipment and receiver.  
Connect the equipment to an outlet on a circuit different from that  
to which the receiver is connected.  
If an abnormal odor or smoke is detected coming  
from the transceiver, turn the power OFF  
immediately. Contact a KENWOOD service station  
or your dealer.  
•
Consult the dealer for technical assistance.  
When condensation occurs inside the transceiver:  
Condensation may occur inside the transceiver in such cases where  
the room is warmed using a heater on cold days or where the

2 After the cable is in place, wind heat-resistant tape  
around the fuse holder to protect it from moisture,  
then tie down the full run of cable.  
DC POWER CABLE CONNECTION  
1
■ Mobile Operation  
3 To prevent the risk of short circuits, disconnect  
other wiring from the negative (–) battery terminal  
before connecting the transceiver.  
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 the transmit output power may drop excessively.  
4 Confirm the correct polarity of the connections,  
then attach the power cable to the battery  
terminals; red connects to the positive (+) terminal  
and black connects to the negative (–) terminal.  
1 Route the supplied DC power cable directly to the  
vehicle’s battery terminals using the shortest path  
from the transceiver.  
•
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.  
•
When using a noise filter, install it with an insulator to  
prevent it from touching metal on the vehicle.  
Red  
•
We recommend that you do not use the cigarette  
lighter socket since some cigarette lighter sockets  
introduce an unacceptable voltage drop.  
Fuse holder  
Black  
•
When routing the power cable through a hole in the  
vehicle chassis or body, for example in the firewall at  
the front of the passenger compartment, use a  
rubber grommet to protect the cable from abrasion.  
Dismantle the fuse holder to pass the cable through  
the firewall.  
5 Reconnect any wiring removed from the negative  
terminal.  
6 Connect the DC power cable to the transceiver’s  
power supply connector.  
•
Press the connectors firmly together until the locking  
tab clicks.  
•
The entire length of the cable must be dressed to  
isolate it from heat, moisture, and the engine  
secondary (high voltage) ignition system/ cables.

2 Connect the DC power cable to the transceiver’s  
power supply connector.  
■ Fixed Station Operation  
In order to use this transceiver for fixed station  
operation, you will need a separate 13.8 V DC power  
supply (purchased separately). We recommend  
using a power supply with a current capacity of 12 A.  
1
•
Press the connectors firmly together until the locking  
tab clicks.  
Note:  
◆
◆
◆
To get the most out of your transceiver, we recommend using  
the optional PS-33 (20.5 A, 25% duty cycle) power supply.  
Before connecting the DC power supply to the transceiver, be  
sure to switch the transceiver and the DC power supply OFF.  
Fuse holder  
Do not plug the DC power supply into an AC outlet until you  
make all connections.  
1 Connect the DC power cable to the regulated DC  
power supply and check that the polarities are  
correct (Red: positive, Black: negative).  
•
Do not directly connect the transceiver to an AC  
outlet. Use the supplied DC power cable to connect  
the transceiver to a regulated power supply.  
•
Do not substitute the cable with smaller gauge wires.

■ Replacing Fuses  
ANTENNA CONNECTION  
If a 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, you must first install an efficient,  
well-tuned antenna. Successful transceiver operation  
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 to match the transceiver  
input impedance. Also use a low-loss coaxial feed line  
that has a characteristic impedance of 50 Ω. 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.

Only use fuses of the specified type and rating; otherwise the  
transceiver could be damaged.  
◆
◆
Transmitting without first connecting an antenna or other matched  
load may damage the transceiver. Always connect an 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.  
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.

■ Selecting Output Power  
TRANSMITTING  
It’s wise to select lower transmit power if communication  
is still reliable. This lowers the risk of interfering with  
others on the band. When operating using battery  
power, you will enjoy more operating time before a  
charge is necessary.  
1 To transmit, press and hold Mic [PTT] and speak into  
the microphone in your normal tone of voice.  
•
“ON AIR” and the RF power meter appear.  
4
Press [LOW] to select high (“H”), medium (“M”), or  
low (“L”) power. The default is high.  
•
You can program a different output power for band A  
and B.  
•
•
Speaking too close to the microphone, or too loudly,  
may increase distortion and reduce intelligibility of your  
signals at the receiving station.  
The RF power meter shows the relative transmit output  
power.  
2 When you finish speaking, release Mic [PTT].  
Time-out Timer: Holding down Mic [PTT] for more than 10 minutes  
causes the transceiver to generate a beep and stop transmitting.  
Release, then press Mic [PTT] to resume transmitting. You can  
change the timer to 3 or 5 minutes {page 67}.  
◆
◆
Do not transmit at high output power for an extended period of  
time. The transceiver could overheat and malfunction.  
Continuous transmission causes the heat sink to overheat.  
Never touch the heat sink when it may be hot.  
Note: When the transceiver overheats because of ambient high  
temperature or continuous transmission, the protective circuit may  
function to lower the transmit output power.

OPERATING THROUGH REPEATERS  
Repeaters, which are often installed and maintained by  
Offset Programming Flow  
radio clubs, are usually located on mountain tops or  
other elevated locations. Generally they 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 communications without using repeaters.  
q
Select a band.  
w
Select a receive frequency.  
6
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 allow it to access. For details, consult  
your local repeater reference.  
e Select an offset direction.  
r
Select an offset frequency.  
(Only when programming odd-split  
repeater frequencies.)  
t
y
Activate the Tone function (if necessary).  
Select a tone frequency (if necessary).  
If you store the above data in a memory channel, you  
need not reprogram every time. See “MEMORY  
CHANNELS” {page 33}.

Some repeaters in Europe must receive continuous  
signals for a certain period of time, following a 1750 Hz  
tone. This transceiver is also capable of remaining in the  
transmit mode for 2 seconds after transmitting a 1750 Hz  
tone.  
TRANSMITTING A 1750 Hz TONE

REVERSE FUNCTION  
AUTOMATIC SIMPLEX CHECK (ASC)  
The reverse function exchanges a separate receive and  
transmit 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  
to free up the repeater.  
While using a repeater, ASC periodically monitors the  
strength of a signal that you receive directly from the  
other station. If the station’s signal is strong enough to  
allow direct contact without a repeater, the ASC indicator  
on the display begins blinking.  
Press [REV] (1 s) to switch the function ON.

APPLICATION EXAMPLES  
Following are examples of how you might use Programmable Memory. These examples may not represent  
applications useful to you, but you will understand the flexibility of this function.  
Solution  
Solution  
Situation 1  
Because 5 PM channels are available, up to 5  
persons can separately program the transceiver and  
store their customized environment. Then each  
person can quickly change to their favorite settings,  
simply by recalling a PM channel.  
You share your transceiver with other members in  
your family or club. However, each individual has  
personal preferences for how they like to set various  
functions. You have to keep changing many settings  
each time you use the transceiver.  
It is too much trouble to change back the settings  
after somebody else has reconfigured them. This  
application can avoid having a feature-rich transceiver  
but never using many useful features.  
8
Situation 2  
Solution  
Solution  
While operating mobile on the way to work every  
morning, you prefer a silent transceiver that does not  
interrupt the morning calm. In addition, you feel that a  
bright display is a waste of power in sunlight. At night,  
when driving home, you realize the Beep function truly  
serves a purpose and you feel it is nice to see a bright  
display after dark.  
In 2 PM channels, store the same operating data such  
as frequency, offset, tone, etc., and store different  
settings for the Display Dimmer and Beep functions.  
Then you can quickly recall the best settings for day  
and night operation.  
Solution  
Solution  
Situation 3  
You cannot figure out how to exit the current mode.  
Simply recall PM channel 1, which contains an exact  
copy of the transceiver default environment. You will  
not lose the contents of any memory channels.

PACKET OPERATION  
A packet is a unit of data transmitted as a whole from  
When you access a local PBBS for the first time, you  
often need to register as a new user. After you are  
successfully registered, it will then be available as your  
home PBBS. E-mail addressed to you will be held under  
a directory, called a mailbox, on your home PBBS.  
one computer to another, on a network. Packets can be  
transmitted on radio waves as well as on communication  
lines. Besides a transceiver and a computer, all you  
need is a terminal node controller (TNC). A TNC  
converts packets to audio tones and vice versa, as one  
of its tasks.  
To send e-mail, you must designate the address of a  
recipient, using their call sign and the call sign of their  
home PBBS; ex. KD6NUH@KJ6HC. In this example,  
e-mail is addressed to KD6NUH whose home PBBS is  
KJ6HC. If your home PBBS cannot find KJ6HC in its  
address file to forward your mail, you must designate the  
address in more detail. You may enter  
A variety of packet applications developed by hams  
include packet bulletin board systems (PBBSs). PBBSs  
are created and maintained by volunteers called System  
Operators (SysOp). You may access one of your local  
PBBSs to send e-mail, download files, or obtain various  
useful information. Thousands of PBBSs, which have  
formed a worldwide network, relay e-mail to its intended  
destination around the world.  
“KD6NUH@KJ6HC.#ABC.CA”, or  
“KD6NUH@KJ6HC.#ABC.CA.USA”, or up to  
“KD6NUH@KJ6HC.#ABC.CA.USA.NA”, as necessary.  
The complete address of a recipient living in the U.S., for  
example, should include an appropriate region code  
(preceded by a #), state, country, and continent  
abbreviations as above.

For further information, consult reference books which  
should be available at any store that handles Amateur  
Radio equipment. Web pages relating to Packet will also  
be helpful. On Internet search engines, use “Packet  
Radio” as a key word to find those web pages.  
Note: If there is an amateur radio club in your area, consider  
becoming a member. You can learn more in an hour from  
experienced hobbyists, than in a month of independent research. Ask  
on the local repeaters, or contact your national amateur radio  
organization for information on local amateur radio clubs.

rates is 10 kΩ. Using a modulator input level that is different than  
these optimum specifications may result in deterioration of S/N  
ratio or signal distortion, which could result in increased errors or a  
complete failure to connect with other stations.
