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.
•[PTT], [MONI], [VOL] and [SQL] can be used while the frequency
lock function is in use. Also, TONE-1, TONE-2, DTMF tones or
DTMF memory contents can be transmitted from the microphone.
Push and hold [(VFO)LOCK] for 1 sec. to toggle
the function ON and OFF.

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.
Using [Y]/[Z] switches
Push [Y] or [Z] to set the selected band’s fre-
quency.
•If VFO mode is not selected, push [VFO] to select it.
•Frequency changes according to the selected tuning
steps. (p. 18)
•Pushing [Y] or [Z] for more than 0.5 sec. activates a
scan. If this happens, push [Y] or [Z] again to stop it.
NOTE:1 MHz steps cannot be used via the [Y]/[Z]
switches.
The display shows that the 1 MHz

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.

➁Push [V/MHz] to select VFO mode if another mode has
been selected.
➂Push [SET] one or more times until “tS” appears as shown
below.
•Pushing [MONI] reverses the order of selection.
•Cancel the DTMF memory function in advance. (p. 48)

RF attenuator: The transceiver has an RF attenuator related
to the [SQL] setting. The attenuator is automatically activated
when [SQL] is rotated further than the 12 o’clock position.
Approx. 10 dB attenuation is obtained at full rotation.

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 operating frequency, etc. are automatically programmed into
a scratch pad memory. See p. 36 for details.
•One-touch PTT function is available. See p. 23 for details.
➃Speak into the microphone using your normal voice level.
•DO NOT hold the microphone too close to your mouth or speak
too loudly. This may distort the signal.
➄Release  [PTT] to return to receive.
Selecting the output power
The transceiver has 4 output power levels to suit your oper-
ating requirements. Low output powers during short-distance
communications may reduce the possibility of interference to
other stations and will reduce current consumption.
➀Push [BAND] one or more times to select the operating
band.
➁Push [LOW] one or more times to select the desired out-
put power.
•The output power can be changed while transmitting.

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

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 transmitting.
One-touch PTT function
The PTT switch can be operated as a one-touch
PTT switch (each push toggles transmit/receive).
Using this function, you can transmit without push-
ing and holding the PTT switch.
To prevent accidental, continuous transmissions
with the one-touch PTT function, the transceiver
has a time-out timer. See p. 59 for details.
ÄPush [FUNC] then [➂PTT-M] to turn the one-touch PTT
function ON.
•The activity indicator lights green.

sounds when returning to receive.
•“$” flashes while transmitting with the one-touch PTT func-
tion.
