Before transmitting, monitor your selected oper-
ating frequency to make sure transmitting won't
cause interference to other stations on the same
frequency. It's good amateur practice to listen
first, and then, even if nothing is heard, ask "is
the frequency in use" once or twice, before you
being operating on that frequency.
Before transmitting, monitor your selected operating
frequency to make sure transmitting won't cause inter-
ference to other stations on the same frequency.
q Push [TRANSMIT] or [PTT] (microphone) to trans-
mit.
• The main band's [TX] indicator lights red.
• When split operation is activated, the sub band's [TX] in-
dicator lights.
w Push [TRANSMIT] again or release [PTT] (micro-
phone) to return to receive.
✔ Adjusting the transmit output power
➥ Rotate [RF PWR].

Before transmitting, monitor your selected operating
frequency to make sure transmitting won't cause inter-
ference to other stations on the same frequency.
q Push [METER] to select the ALC meter.
w Push [PTT] (microphone) to transmit.
• Talk into the microphone at your normal voice level.
e While talking into the microphone, rotate [MIC] so
that the ALC meter reading doesn't go outside the
ALC zone. (see at left)
r Release [PTT] (microphone) to return to receive.
