[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.
2 When 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.

Do not transmit at high output power for an extended period of
time. The transceiver could overheat and malfunction.

Note: When the transceiver overheats because of ambient high
temperature or continuous transmission, the protective circuit may
function to lower transmit output power.
