BASIC OPERATION
■
Transmitting
CAUTION:
Transmitting without an antenna will dam-
age the transceiver.
NOTE:
To prevent interference, listen on the channel
before transmitting by opening the squelch. To open
the squelch, rotate
[DIAL]
counterclockwise or push
[SQL
Z
]
on the microphone.
q
Set the operating frequency. (p. 5)
•
Adjust the output power if desired. See page 11 for
the details.
w
Hold down
[PTT]
to transmit.
•
The
“

• The S/RF indicator shows the output power level.
•
The One-Touch PTT function can be used. See
page 11 for details.
e
Speak into the microphone at your normal voice level.
•
DO NOT hold the microphone too close to your mouth,
or speak too loudly. This may distort the signal.

IMPORTANT!
(for 65 W transmission)
:
The IC-2300H has a built-in current detector circuit
which protects the power amplifi er from excessive cur-
rent fl ow. When excessive current fl ow is detected, the
circuit automatically reduces the transmit output power
to approximately 25 watts.
The IC-2300H has a thermal detector circuit too, which
protects the power amplifi er from excessive heat. As
the temperature increases, the circuit automatically re-
duces the transmit output power to approximately 10 to
20 watts.
