Ext. Power jack
DC cable
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:

5. Basic Operations
PWR key
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 level,
counterclockwise to decrease. Set it at the desired level.
Squelch level setting
A squelch eliminates white-noise (the background noise when
a signal is not received).
Higher level 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 displayed. 21 levels, between 0 and 20, are available. “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 normal 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.

5. Basic Operation
VFO mode
VFO tuning is set as a default mode at the factory. VFO (variable 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
transceiver.
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, counterclockwise to decrease. The UP/DOWN keys on the microphone 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.

Changing the channel step
1. Be sure the unit is in VFO mode. Refer to page
21 to enter into the SET mode.
5. Basic Operation
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.
REPEATER (DUPLEX) Operation
Shift Direction and Offset frequency setting
Conventional repeaters are operated in the DUPLEX mode.
It receives 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 positive, and if it is lower, the shift
direction is negative. The offset is variable between 0 to 99.995
MHz on this unit.
Display for channel step
at-600 kHz
Press the F key. While the F icon stays on the display, press
MHz key. The display shows the current status of shift direction and offset frequency. The default value is 0.60 MHz (600
kHz) in the negative direction. Press MHz key until the desired offset direction is set. If SIMPLEX mode (without changing transmit and receive frequency) is desired, select the position where both - and + icons disappeared.
Shift release
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.
15
5. Basic Operation
CTCSS / DCS setting
Many repeaters require a CTCSS tone or a DCS code encode setting as a “key” to access the
system, so-called “selective-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 received. The combination of CTCSS squelch and DCS function is not available; only one or the other may be used for
a given 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
88.5
The original status
T/SQ
88.5
DCS

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.
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 relative status icon T/TQ/DCS disappears.
The CTCSS encoding and decoding frequencies may be set differently. The encode setting frequency automatically relates to the decode setting, but decode setting does not affect encode. The
standard set of 39 different CTCSS tones are available as shown on the chart below. DCS encode/
decode cannot be separated and are selectable from 104 codes as shown below.

keys to select the desired memory channel number into which the current VFO settings will be
copied. An empty channel is shown with a flashing M icon. It may be a good practice to “allocate” 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 reserve, 80-98 simplex reserve. It makes references easier for the operation and future modifications of the memory channels.

[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 receive
NOTE: Only the frequency can be stored in PH and PL channels to determine the edges of the program
scan range.

5. Basic Operation
CALL mode
This is a memory mode that allows the transceiver to quickly recall the assigned memory channel
by simply pressing the CALL key, regardless of the current status of the unit.
1. Press CALL key. The C icon appears on the
display and the transceiver enters the CALL
mode. In this mode, the main dial or the UP/
DOWN keys cannot change the frequency or
memory channels.
2. Press CALL key again or press V/M key to exit
CALL mode.
3. No scan functions are available in CALL mode.
To store a desired setting in the CALL channel, follow the memory mode programming instructions and assign your selected settings to memory channel C. The call channel can be modified but
cannot be eliminated or hidden.
To receive signals
• Be sure to have the unit connected to the appropriate antenna, powered on, set the audio volume and
squelch level properly.
• Select the desired receiving frequency or browse frequencies to listen to ongoing communications. The
S-meter shows relative signal strength between BUSY and FULL when the transceiver detects an incoming
signal.
• If the S-meter indicates an incoming signal but nothing is heard from a speaker, check audio level, squelch
level, and CTCSS/DCS decoding status, which are explained elsewhere in this manual.
• A Monitor function is available to receive weaker signals. Press and hold SQL key for more than 1 second.
Regardless of the level setting of the squelch, it will be opened and the BUSY icon turns on the display.
Press any key on the front panel to exit.

5. Basic Operation
To transmit
1. Select the desired frequency. Be sure that you
are authorized to operate on the selected frequency. Check the system and monitor the fre-
quency to make sure that you are not going to
disturb any ongoing communications.
2. Select the output power. Press FUNC key and
then press CALL key while F icon is on the
display. As the CALL key is pressed, the output power changes among 3 levels. The Lo icon
stands for LOW power setting, Mi for MEDIUM power. When the transceiver is set at
HIGH power, no icon will appear. The output
power level cannot be changed during transmission.
3. Default setting is High power. Press the PTT
key on the microphone to transmit, release it to
receive. During transmission, the relative power
output is shown on the RF meter as:
LOW power = 2 segments
MID power = 3 segments
HIGH power = 5 segments.
LOW power
MID power
20
HIGH power
4. If operating from a vehicle, do not transmit for
extended periods without running the engine,
to avoid battery drainage. Check the battery
voltage often. The lights, windshield wipers,
stereo system, air-conditioner, defogger and
other accessories drain the battery’s power considerably. When those accessories are turned
on, reduce the output power or turn off one or
more accessories to avoid the battery becoming overloaded. Watch the road when driving.
Check local regulations that may pertain to the
use of a transceiver when driving.
6. Parameter Setting Mode
IMPORTANT: Please read the following pages thoroughly prior to the change of any parameters.
THE PARAMETERS CANNOT BE SET WITHOUT ENTERING THE SET MODE.
By entering the Parameter Setting mode, some of the radio’s operating parameters can be changed
to suit your application. The following is the Selectable Parameters’ Menu.
Note: The Alphanumeric Channel Tag setting will not appear in the menu until memories have been programmed
first!
To use the Parameter Setting mode
1. Press FUNC key for more than 2 seconds to
enter the Parameter Setting mode.
Use SQL key or UP/DOWN keys to select
menu.
2. Rotate the main dial to select the desired set-
ting.
3. Press SQL or UP/DOWN keys again to enter
the selected setting into the radio’s memory. The
transceiver is now ready for additional Parameter adjustments.
Default setting
4. Press any key OTHER than SQL/UP/DOWN
to exit the Parameter mode. The only exception is the Channel Tag setting which accepts
only PTT, FUNC, MHz and TS/DCS keys to
exit.

Channel Step setting:
This is to select the channel step to be used in the VFO mode.
Refer to the chart below for the relation of the actual step
frequency and how it is displayed.
Scan Type
This is to select the scan resume condition. TIMER setting
allows the radio to resume scanning after 5 seconds, regardless of the signal receiving status. BUSY setting resumes scanning when the received signal is gone. The scan mode is explained later.
Beep Sound
BEEP-ON setting enables a beep that sounds after certain keys
are touched and/or setting is done. BEEP-OF shows that the
beep function is off.

6. Parameters Setting Mode
Time-Out-Timer
The TOT feature is popular in repeater systems. It prohibits the users from transmitting on the
repeater after a certain period of time has elapsed. By setting this function and activating it according to the repeaters’ requirement, the radio alerts the user by a beep 5 seconds prior to time-out.
When the time is expired, transmitting stops and the transceiver automatically returns to receiving
mode. This avoids the repeater going into its TOT mode. Until the PTT is released once and pressed
again, the transceiver will not transmit.
1. In this Menu the default display shows TOT-
OFF.
2. Rotate the main dial to select time-out time.
The display should change as shown. The number followed by TOT is the time-out time in
seconds.
3. The TOT feature is selectable up to 450 sec-
onds (7.5 minutes).
during the setting time of 60 seconds
TOT Penalty
When the transmission is shut down in the TOT mode, this function prohibits another transmission
for a selected time period.
1. During the TOT penalty period, the beep sounds
when the PTT is pressed but the radio does not
transmit.
2. If the PTT is continuously pressed over both
TOT and the TOT penalty period, this function
will be automatically cancelled.
3. Default setting is TP-OFF. Rotate the main dial
to select the penalty time, up to 15 seconds.

6. Parameters Setting Mode
APO-Auto Power OFF
This feature will automatically shut off the transceiver. It is useful for mobile operation to avoid
draining the car battery. If there is no activity or use of the radio, it will turn off automatically after
30 minutes followed by a beep sound.
1. Default is APO-OFF.
2. Rotate dial to select APO-ON to activate the
function.
during the ON setting
Tone-Burst Frequency
This is to access Tone-Burst repeaters which require a certain pitch of audible tone to activate
“sleeping” repeaters. Usually, a repeater system does not require the tone once the repeater is
activated.
1. The default is TB-1750, which is 1750 Hz tone.
2. It is selectable from 1750, 2100, 1000, 1450 Hz.
during the 1750 Hz frequency
See ADVANCED OPERATION chapter for operation.
Busy-Channel-Lock-Out
This function prohibits transmission as long as there is a signal on the receiving frequency.
The default is BCLO-OF, which is the off position. By activating this function, the radio transmits
only when:
1. No signal is received (BUSY icon is gone) on
the receiving frequency.
2. Tone-squelch is opened by the corresponding
CTCSS tone of the receiving signal.
3. As above, with DCS code.
Otherwise a beep sounds but the unit does not transmit even
when the PTT is pressed.
during the ON setting
Theft Alarm
Default is SCR-OFF. Select ON or DLY to activate the function. When the SCR-ON is selected, 100 MHz and 100 kHz
order decimal points will appear on the display.
