q Push [METER] to select the ALC meter.
w Push [PTT] (microphone) to transmit.
• Talk into the microphone at your normal voice level.

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.
