OPERATING BASICS
SWITCHING THE POWER ON/OFF
1Press [  ] (Power) to switch the transceiver power ON.
•A high pitched double beep sounds and a Power-on
message {page 60} appears briefly, followed by the
frequency and other indicators.
2To switch the transceiver OFF, press [  ] (Power) (1s).
•When you turn the transceiver OFF, a low pitched
double beep sounds.
•The transceiver stores the current frequency and
parameters when it is turned OFF and recalls these
parameters the next time you turn the transceiver ON.
ADJUSTING THE VOLUME
Turn the Volume control clockwise to increase the audio
output level and counterclockwise to decrease the output
level.
•If you are not receiving a signal, press the Mic PF key
assigned the MONI function {page 59}, then adjust the
Vo lume control to a comfortable audio output level.  Press
the MONI key again to cancel the Monitor function.
ADJUSTING THE SQUELCH
The purpose of Squelch is to mute the speaker when no
signals are present.  With the squelch level correctly set,
you will hear sound only while actually receiving signals.
The higher the selected squelch level, the stronger the
signals must be to receive.
The appropriate squelch level depends on the ambient
RF noise conditions.
1Press [F], [REV].
•The current squelch level appears.
2Turn the Tuning control to adjust the level.
•Select the level at which the background noise is just
eliminated when no signal is present.
•The higher the level, the stronger the signals must be to
receive.
•10 different levels can be set.
(0: Minimum  ~ 9: Maximum; 1 is the default value)
3Press any key other than [  ] (Power) to store the
new setting and exit the squelch adjustment.

TRANSMITTING
1To transmit, hold the microphone approximately 5 cm
(2 inches) from your mouth, then press and hold Mic
[PTT] and speak into the microphone in your normal
tone of voice.
•“” and the RF Power meter appears.  The RF
Power meter shows the relative transmit output power
(
).
•If you press Mic [PTT] while you are outside the
transmission coverage, a high pitched error beep
sounds.
2When you finish speaking, release Mic [PTT].
Note:  If you continuously transmit for longer than the time specified in
Menu No. 21 (default is 10 minutes) {page 62}, the internal time-out
timer generates a warning beep and the transceiver stops transmitting.
In this case, release Mic [PTT] and let the transceiver cool down for a
while, then press Mic [PTT] again to resume transmission.
SELECTING AN OUTPUT POWER
You can configure different power levels for transmission.
1Press [F], [MENU] and turn the Tuning control to
select Menu No. 6 (TXP).
2Press [MENU] and turn the Tuning control to select
“H” (high; default) or “L” (low) power.3Press [MENU] to store the setting or any other key to
cancel.
4Press any key other than [MENU] to exit Menu Mode.
◆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 transmit output power.
SELECTING A FREQUENCY
VFO M
ODE
This is the basic mode for changing the operating
frequency.  To enter VFO Mode, press [VFO].
Turn the Tuning control clockwise to increase the
frequency and counterclockwise to decrease the
frequency, or use Mic [UP]/[DWN].
•Press and hold Mic [UP]/[DWN] to step the frequency
repeatedly.

MHZ MODE
If the desired operating frequency is far away from the
current frequency, it is quicker to use the MHz Tuning
Mode.
To adjust the MHz digit:
1While in VFO or Call Mode, press [MENU].
•The MHz digit blinks.
2Turn the Tuning control to select the desired MHz
value.
3Press any key to set the selected frequency and
return to normal VFO Mode.
4Continue adjusting the frequency as necessary, using
the Tuning control or Mic [UP]/[DWN].
DIRECT FREQUENCY ENTRY
In addition to turning the Tuning control or pressing Mic
[UP]/[DWN], there is another way to select the
frequency.  When the desired frequency is far away from
the current frequency, you can directly enter a frequency
using the Mic keypad (keypad models only).
1Press [VFO].
•You must be in VFO mode to make a direct frequency
entry.
2Press the Mic PF key assigned the ENTER function
{page 59}.
3Press the numeric keys ([0] to [9]) to enter your
desired frequency.
•Pressing Mic [Enter] fills all remaining digits (the digits
you did not enter) with 0 and completes the entry.  For
example, to select 145.000 MHz, press [1], [4], [5] and
press Mic [Enter] to complete the entry.
•If you want to revise the MHz digits only, leaving the kHz
digits as they are, press Mic [VFO] in place of [Enter].

MENU SETUP
WHAT IS A MENU?
Many functions on this transceiver are selected or
configured via a software-controlled Menu rather than
through the physical controls of the transceiver.  Once
you become familiar with the Menu system, you will
appreciate its versatility.  You can customize the various
timings, settings, and programming functions on this
transceiver to meet your needs without using many
controls and switches.
MENU ACCESS
1Press [F], [MENU].
•A brief explanation of the menu, and the setting and
Menu No. appear on the display.
Menu NameSettingMenu Number
2Turn the Tuning control to select your desired Menu.
•As you change the Menu No., a brief explanation of
each menu appears along with its current parameter.
3Press [MENU] to configure the parameter of the
currently selected Menu No.
4Turn the Tuning control to select your desired
parameter.
5Press [MENU] to store the new setting or any other
key to cancel.
6Press any key other than [MENU] to exit Menu Mode.

OPERATING THROUGH REPEATERS
Repeaters, which are often installed and maintained 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.
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.
TX:  144.725 MHz
TX tone:  88.5 Hz
RX:  145.325 MHz TX:  144.725 MHz
TX tone:  88.5 Hz
RX:  145.325 MHz

PROGRAMMING AN OFFSET
You must first select an amateur radio repeater downlink
frequency as described in “S
ELECTING AN OFFSET
FREQUENCY”.
SELECTING AN OFFSET DIRECTION
Select whether the transmit frequency will be higher (+)
or lower (–) than the receive frequency.
1Press [F], [MENU] and turn the Tuning control to
select Menu No. 5 (SFT).
2Press [MENU] and turn the Tuning control to select
“+” or “–”.
3Press [MENU] to store the setting or any other key to
cancel.
4Press any key other than [MENU] to exit Menu Mode.
•“+” or “–” appears above the frequency, indicating which
offset direction is selected.
If the offset transmit frequency falls outside the allowable
range, transmission is inhibited.  In this case, adjust the
reception frequency so that the transmit frequency is
within the band limits or change the offset direction.
Note:  While using an odd-split memory channel or transmitting, youcannot change the offset direction.
SELECTING AN OFFSET FREQUENCY
To access a repeater which requires an odd-split
frequency pair, change the offset frequency from the
default which is used by most repeaters.  The default
offset frequency is 600 kHz.
1Press [F], [MENU] and turn the Tuning control to
select Menu No. 10 (OFFSET).
2Press [MENU] and turn the Tuning control to select
the appropriate offset frequency.
•The selectable range is from 0.00 MHz to 69.95 MHz in
steps of 50 kHz.
3Press [MENU] to store the setting or any other key to
cancel.
4Press any key other than [MENU] to exit Menu Mode.
Note:  After changing the offset frequency, the new offset frequencywill also be used by Automatic Repeater Offset.
