Transmitting
NOTE: To prevent interference, listen on the channel be-
fore transmitting by pushing [DUPMONI] for 1 sec., or
[
MONI
1(BANK)] on the microphone.
qSelect the main band. (p. 11)
wSet the operating frequency. (pgs. 1113)
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. 21 for details.
•“Si may blinks instead of the sub bands memory channel num-
ber indication according to the selected frequency band.
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.
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 [LOWPRIO] once or twice to select the output
power.
*approx.
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;
[
MID
5(DTCSS)] for middle output power; and
[
LOW
6(DTMF)] for low output power.
The output power can be changed via the microphone
during receive only.

IMPORTANT! (for 50/35 W transmission):
The IC-2720H 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.
CAUTION: Transmitting without an antenna will damage
the transceiver.
