3. Initial Installation
External power supply control & power lamp unctions
Be sure the vehicle has a negative ground, 12VDC electric system before installation. Connect the
provided DC cable directly to the battery as shown below to minimize any possible ignition noise.
Be sure the vehicle has a large capacity battery as the use of the transceiver may overload the
electric system of the vehicle.
If the ignition key on/off feature is desired (optional feature), use the optional EDC 37 (For direct
connection to the circuit on the vehicle) or EDC 36 (for a Cigar Plug connection) cable. Connect
one of the cables between the ACC terminal or a Cigar Plug that operates with the vehicle ignition
or ACC switch on the vehicle and EXT POWER jack on the rear side of the unit. (Note: In many
cars, the cigar lighter plug is always powered. If this is the case, you cannot use it for the ignition
key on/off function.) If this option is selected, the unit can be turned on/off either manually or
automatically in accordance with the ignition key position:
1. When the ignition key is turned to ACC or ON (Start) position with the radio turned
off, the power switch illuminates. The illumination will be turned off when the igni-
tion key is turned to the off position. To turn on the unit, press the power switch
manually while it is illuminated (while ignition key is at ACC or ON position).
2. When the ignition key is turned to ACC or ON position with the radio's power switch
on, the unit turns on automatically and the power switch will be lit. Turn the ignition
key to OFF position or manually turn the power switch off to shut down the radio.
The power consumption when using the additional cable is 5mA.
For operation without this option, use the power switch to turn the unit on/off.
Power supply voltage display unction
After connecting the transceiver to the power supply, the supply voltage can be confirmed by
pressing the SQL key together with the FUNC key. The supply voltage to the transceiver is then
seen on the display.
The transceiver will return to its normal operation when the power is switched OFF.
The display immediately changes as the voltage supply changes.
It also displays voltage during transmission.
IMPORTANT: The range of the displayed voltage is only from 7V - 16VDC. Because the displayed value
is estimated, please use a voltmeter when a more precise reading is desired.

5. Basic Operations
Turning the unit on and off
Press the power switch or turn the ignition key to ACC or ON
position according to the option selected during installation.
Press the power switch again or turn the ignition key to OFF
position to turn off.
Audio Volume level setting
Rotate the VOL knob clockwise to increase the audio le el,
counterclockwise to decrease. Set it at the desired le el.
Squelch level setting
A squelch eliminates white-noise (the background noise when
a signal is not recei ed).
Higher le el settings will keep the squelch “closed” more
tightly for quieter monitoring, but weak signals will not be
heard. Lower settings allow weaker signals to “open” the
squelch but noise may also cause it to open.
1. Press SQL key. SQL icon appears on the dis-
play and the squelch level will be shown at the
position where the memory number is dis-
played. 21 levels, between 0 and 20, are avail-
able. “0” is the lowest setting.
2. By rotating the main dial or by using the UP/
DOWN keys on the microphone, adjust the
squelch to the desired level. To return to nor-
mal use, press PTT or any key on the front
panel; or if there are no operations within 5
seconds, the unit will store the setting and will
return to its original status.
The new squelch le el will be stored in the CPU until another
adjustment is done.

5. Basic Opera ion
VFO mode
VFO tuning is set as a default mode at the factory. VFO ( ari-
able frequency oscillator) allows you to change the frequency
in accordance with the selected channel step as you rotate the
main dial or by using the UP/DOWN keys on the microphone.
VFO mode is also used to program the data to be stored in the
memory channels or to change the parameter settings of the
transcei er.
1. Identify the current mode by checking the dis-
play. If “M” or “C” icon is NOT displayed on
it, the unit is already in the VFO mode.
2. Otherwise press “V/M” keys until those icons
are gone.
[Change frequency by the channel step]
Rotate the main dial clockwise to increase the frequency, coun-
terclockwise to decrease. The UP/DOWN keys on the micro-
phone act in the same way.
[Change frequency by 1 MHz step]
This will enable a quick change of frequency in 1 MHz steps:
1. Press MHz key. The digits after 100 kHz will
disappear from the display.
2. Follow the same sequence as above to change
the value.

5. Basic Opera ion
RE EATER (DU LEX) Operation
Shift Direction and Offset frequency setting
Con entional repeaters are operated in the DUPLEX mode.
It recei es an incoming signal (UP-LINK) on one frequency
and re-transmits on another (DOWN-LINK). The difference
between these two frequencies is called the offset frequency.
If the UP-LINK frequency is higher than the DOWN-LINK
frequency, the direction is positi e, and if it is lower, the shift
direction is negati e. The offset is ariable between 0 to 99.995
MHz on this unit.
Press the F key. While the F icon stays on the display, press
MHz key. The display shows the current status of shift direc-
tion and offset frequency. The default alue is 0.60 MHz (600
kHz) in the negati e direction. Press MHz key until the de-
sired offset direction is set. If SIMPLEX mode (without chang-
ing transmit and recei e frequency) is desired, select the po-
sition where both - and + icons disappeared.
Shif release
at-600 kHz
Changing the channel step
1. Be sure the unit is in VFO mode. Refer to page
21 to enter into the SET mode.
2. Select the channel step parameter setting using
the tuning knob. The current channel step will
be displayed as below.
3. Press PTT or any one of the keys except SQL
on the front panel to enter the desired step into
the transceiver’s memory. The display will then
return to the original status.
Please note that settings below 10 kHz may be automatically
corrected according to the selected step.
Display for channel step
1. Rotate the dial or use UP/DOWN keys on the microphone to change the shift fre-
quency. It changes in accordance with the channel step setting.
2. In this mode, if the F key is pressed again, the offset frequency can be changed in
1 MHz steps for faster setting.
3. Press PTT or any key except F or MHz on the front panel to return to the original
status.

5. Basic Opera ion
CTCSS / DCS setting
Many repeaters require a CTCSS tone or a DCS code encode setting as a “key” to access the
system, so-called “selecti e-calling”. Sometimes, CTCSS or DCS decode features are used on the
output of a repeater so they can be used as a squelch. In this mode, regardless of the main squelch
status, the audio can be heard ONLY when the matching tone/code signal is recei ed. The combi-
nation of CTCSS squelch and DCS function is not a ailable; only one or the other may be used for
a gi en memory channel.
1. Press TS/DCS key. The current setting will be
displayed with T/SQ/DCS icons and relative
frequency/code. Press the same key to select
T/SQ/DCS setting.
2. The numbers (such as 88.5) represent the CTCSS frequency in Hz. When it is dis-
played with the T icon only, the unit transmits the sub-audible tone while the PTT is
pressed (encode) and the repeater access is enabled (assuming the repeater is using
88.5).
3. Press the same key again so that the SQ icon shows up on the display. This is the
CTCSS decode frequency. This enables CTCSS squelch (or Tone Squelch, TSQ).
4. Press it again so that the 3-digit number and DCS icon is displayed. This is the DCS
code, and it enables DCS encoding and decoding.

The original s a us
For 2 - 4, rotate the main dial or press the UP/DOWN keys to change tone or code. Press any key
(Except TS/DCS, UP/DOWN keys) to enter the setting and return to original status. The T/SQ/
DCS icon will remain on the display to show the current status. To exit, simply use the TS/DCS key
and press it until the relati e status icon T/TQ/DCS disappears.
The CTCSS encoding and decoding frequencies may be set differently. The encode setting fre-
quency automatically relates to the decode setting, but decode setting does not affect encode. The
standard set of 39 different CTCSS tones are a ailable as shown on the chart below. DCS encode/
decode cannot be separated and are selectable from 104 codes as shown below.
NOTE: Depending on he devia ion level of he incoming DCS coded-signal, your radio may no open he DCS
squelch. If his occurs, re urn o DCS se ing mode and press he CALL key. A decimal poin appears on
he 10 MHz order; hen se he desired code. This se ing can also be s ored in a memory channel.

ber into which the current VFO settings will be
copied. An empty channel is shown with a flash-
ing M icon. It may be a good practice to “allo-
cate” memory channels in order, such as 0-9
for local repeaters, 10-19 local simplex, 20-49
repeaters within the area, 50-79 for repeater re-
serve, 80-98 simplex reserve. It makes refer-
ences easier for the operation and future modi-
fications of the memory channels.

5. Basic Opera ion
[Programmable data in the memory channel]
Some features will be explained later, so please read this instruction manual thoroughly prior to
programming memories.
Memory channels including 0 - 99 and CALL can store following:
• Frequency
• Shift frequency
• Shift direction
• CTCSS tone both encode and decode
• Tone Squelch setting
• DCS code both encode and decode
• DCS squelch setting
• Scan skip channel
• Busy Channel Lock Out setting
• Priority monitoring frequency (PC programming required)
• Normal/Narrow FM width
• AM air-band recei e
NOTE: Only he frequency can be s ored in PH and PL channels o de ermine he edges of he program
scan range.
4. While F icon is on the display, press MW key.
The VFO settings are copied to the memory
channel and a beep will sound. The memory
channel can be over-written if a previously pro-
grammed channel is selected (the memory
channels shown with a stable M icon).
5. To program the CALL channel (quick recall)
select the channel shown with CH-C on the dis-
play. Save Ch99 to store the setting used for
the Alarm operation, which will be explained
later. Use PL and PH for Program scan setting,
which will be explained in the advanced op-
erations chapter.
6. To delete a programmed channel, select it in
memory mode, press FUNC key then press the
MW key while F icon is on. The memory is de-
leted and a beep sounds. The M icon starts flash-
ing showing that this channel is now empty.
7. To undo delete, repeat 6. However, the Undo
function becomes impossible once the channel
or the mode is changed.
