Lock functions
To prevent accidental frequency changes and unnecessary
function access, use the lock function. The transceiver has 2
different lock functions.
DFrequency lock
This function locks the tuning dial and switches electronically
and can be used together with the microphone lock function.
Push and hold  until “L” appears in the memory chan-
nel readout to activate the function.
•To cancel the function, push and hold  until “L” disappears.

3SETTING A FREQUENCY
17
Using the tuning dial
➀Push [BAND] to select the desired band, if necessary.
➁Rotate the tuning dial to set the frequency.
•If VFO mode is not selected, push the [V/MHz] to select VFO
mode.
•Frequency changes according to the selected tuning steps.
(p. 18)
➂For the 1 MHz frequency setting, rotate the tuning dial after
pushing [V/MHz].
•Pushing [V/MHz] for 1 sec. starts a scan function. If this happens,
push [V/MHz] again to stop the scan.

Tuning step selection
Tuning steps are the minimum frequency change increments
when you rotate the tuning dial or push the [Y] or [Z]
switches on the microphone. The following tuning steps are
available:
•5 kHz•10 kHz•12.5 kHz•15 kHz
•20 kHz•25 kHz•30 kHz•50 kHz
NOTE:For convenience, select a tuning step that
matches the frequency intervals of repeaters in your area.
➀Push [BAND] to select the desired band, if necessary.
➁Push [V/MHz] to select VFO mode if another mode has
been...

3SETTING A FREQUENCY

Using the keypad
The frequency can be directly set via numeral
keys on the microphone.
ÄPush [BAND] to set the operating band, if necessary.
ÅPush [VFO] to select VFO mode.
ÇPush [ENT] to activate the keypad for digit input.
ÉPush 5 keys to input a frequency.
•When a digit is mistakenly input, push [ENT] to clear the input,
then input from the 1st digit.
•Pushing [CLR] clears input digits and retrieves the frequency.
ÑPush [Y] or [Z] to make adjustments below the 10 kHz
digit, if...

Receiving
➀Push [PWR] for 1 sec. to turn power ON.
➁Push [BAND] to select a band.
➂Set the audio level.
➥Push [MONI] to open the squelch.
➥Rotate the [VOL] control to adjust the audio output level.
➥Push [MONI] again to close the squelch.
➃Set the squelch level.
➥Rotate [SQL] fully counterclockwise in advance.
➥Rotate [SQL] clockwise until the noise just disappears.
➥When interference is received, rotate [SQL] clockwise
again for attenuator operation.
➄Set the operating frequency....

Avionics band receive(U.S.A. version only)
AM mode can be selected over the range of 118.000 to
135.995 MHz for reception of avionics-related broadcasts.
➀Push [BAND] one or more times to select the aviation
band.
➁Push and hold [BAND] to toggle between AM and FM
modes.
•Mode selection cannot be performed via the microphone.
✔CONVENIENT
The tuning steps for the avionics band are available sepa-
rately from those for other ranges.
Appears when AM mode is selected.

Transmitting
CAUTION:Transmitting without an antenna may dam-
age the transceiver.
NOTE:To prevent interference, listen on the frequency be-
fore transmitting by pushing [MONI] or [➀MONI] on the mi-
crophone.
➀Push [BAND] one or more times to select the operating
band.
➁Set the operating frequency. (pgs. 15–19)
•Select output power if desired. See section at right for details.
➂Push and hold [PTT] to transmit.
•“$” appears.
•The S/RF indicator shows the output power selection.
•The...

4BASIC OPERATION
23The microphone can select the desired output
power directly.
ÄPush [BAND] to select the desired band, if nec-
essary.
ÅPush [➃HIGH] for high output power; [➄MID] for
mid-high output power; [➅LOW] for low output
power.
•“MID-LO” output power CANNOT be selected via
these microphone keys, however, the default setting
for [F-1] is output power selection—“MID-LO” output
power CAN be selected using [F-1], in this case.
•The output power CANNOT be changed via the mi-
crophone while...

REPEATER OPERATION5
24
Accessing a repeater
➀Push [BAND] one or more times to select the desired band.
➁Set the receive frequency (repeater output frequency).
(pgs. 15–19)
➂Push and hold  for 1 sec., one or more times, to se-
lect –duplex or + duplex.
•“DUP –” or “DUP” appears to indicate the transmit frequency for
minus shift or plus shift, respectively.
•When the auto repeater function is turned ON, (available for the
U.S.A. version only), steps ➁, ➂are not necessary. (p. 31)
➃Push [TONE] one or more...

ÄPush [BAND] to select the desired band, if nec-
essary.
ÅSet the receive frequency (repeater output fre-
quency). (pgs. 15–19)
ÇPush [➆DUP–] to select –duplex; push
[➇DUP+] for + duplex.
ÉPush [FUNC] then [➆TONE] to turn ON the
subaudible tone encoder according to repeater
requirements.
•Refer to p. 26 for tone frequency setting.
•When the repeater requires a different tone system,
see at right.
