214TRANSMITTING1 To transmit, press and hold Mic [PTT] and speak intothe microphone in a normal tone of voice.• “ON AIR” and the RF power meter appear.• Speaking too close to the microphone, or too loudly,may increase distortion and reduce intelligibility of yoursignals at the receiving station.• The RF power meter shows the relative transmit outputpower.2 When you finish speaking, release Mic [PTT].Time-Out Timer: Holding down Mic [PTT] for more than 10 minutescauses the transceiver to generate a beep and stop transmitting.Release, then press Mic [PTT] to resume transmitting. You may changethe time-out time to 3 or 5 minutes {page 70}.n Selecting Output PowerIt’s wise to select lower transmit power if communicationis still reliable. This lowers the risk of interfering withothers on the band. When operating from batterypower, you will enjoy more operating time before acharge is necessary.Press [LOW] to select high (“H”), medium (“M”), orlow (“L”) power. The default is high.• You can program a different power for band A and B.uDo not transmit at high output power for an extended period oftime. The transceiver could overheat and malfunction.uContinuous transmission causes the heat sink to overheat.Never touch the heat sink when it may be hot.Note: When the transceiver overheats because of ambient hightemperature or continuous transmission, the protective circuit mayfunction to lower transmit output power.
