TRANSMITTING

1When ready to begin transmitting, press and hold Mic [PTT] and speak 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 your signal

at the receiving station.

•The RF power meter shows the relative transmit output power.

2When you finish speaking, release Mic [PTT].

MC-53DM

■Selecting Output Power

It’s wise, and required by law, to select the lowest power that allows reliable communication. If operating from battery power, lower transmit power will give you more operating time before a charge is necessary. Reducing power lowers the risk of interfering with others on the band.

Press [LOW] to select the transmit power you require.

CAUTION:

◆DO NOT TRANSMIT WITH HIGH OUTPUT POWER FOR EXTENDED PERIODS. THE TRANSCEIVER MAY OVERHEAT AND MALFUNCTION.

◆CONTINUOUS TRANSMISSIONS CAUSE THE RADIATOR TO OVERHEAT. NEVER TOUCH THE RADIATOR IN SUCH A SITUATION.

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