3 BASIC OPERATION

■Transmitting

CAUTION: Transmitting without an antenna will damage the transceiver.

☞NOTE: To prevent interference, listen on the channel be- fore transmitting by pushing [MONI•DTMF] on the front panel or [MONI 1(BANK)] on the microphone.

qSelect the frequency band. (p. 11)

wSet the operating frequency. (pgs. 11, 12)

•Select output power if desired. See section at right for details. ePush and hold [PTT] to transmit.

•“$” appears.

•The S/RF indicator shows the output power selection.

•A one-touch PTT function is available. See p. 18 for details. rSpeak into the microphone using your normal voice level.

•DO NOT hold the microphone too close to your mouth or speak too loudly. This may distort the signal.

tRelease [PTT] to return to receive.

IMPORTANT! (for 55/50 W transmission):

The IC-208H is equipped with protection circuit to protect the power amplifier circuit from high SWR (Standing Wave Ratio) and temperature. When a high SWR antenna or no antenna is connected, or when the transceiver temperature becomes extremely high, the transceiver reduces transmit output power to 15 W (approx.) automatically.

■Selecting output power

The transceiver has 3 output power levels to suit your oper- ating requirements. Low output powers during short-distance communications may reduce the possibility of interference to other stations and will reduce current consumption.

➥Push [LOW•DUP] once or twice to select the output power.

• The output power can be changed while transmitting.

The microphone can also be used to select output power.

➥Push [HIGH 4(DTCS)] for high output power;

HIGH [MID 5(DTCSS)] for middle output power; and

4[LOW 6(DTMF)] for low output power.

• The output power can be changed via the microphone
