Receiving
qSet the audio level for the main band.
Push the desired band’s [MAIN•BAND].
Push and hold [DUP•MONI] for 1 sec. to open the
squelch.
Rotate the main band’s [VOL] to adjust the audio level.
Push the [DUP•MONI] to close the squelch.
wSet the squelch level.
Rotate the main band’s [SQL] fully counterclockwise in
advance, then rotate the [SQL] clockwise until the noise
just disappears.
When interference due to strong signals is received, rotate
[SQL] clockwise past 12 o'clock for attenuator operation. (p. 22)
eSet the operating frequency in the main band. (pgs. 15–17)
rWhen receiving a signal on the selected frequency, squelch
opens and the transceiver emits audio.
“BUSY” appears and the S/RF
indicator shows the relative
signal strength for the re-
ceived signal.
CONVENIENT!
The main band’s audio and squelch level can also
be adjusted with [
VOL
Y(TONE-1)]/[
VOL
Z 0(TONE-2)]
and [
SQL
Y D(MUTE)]/[
SQL
Z #(16KEY-L)], respectively.
“VOL” for audio or “SQL” for squelch appears during set.
Transmitting
NOTE: To prevent interference, listen on the channel be-
fore transmitting by pushing and holding [DUP•MONI] for
1 sec., or [
MONI
1(BANK)] on the microphone.
qSelect the main band. (p. 15)
wSet the operating frequency. (pgs. 15–17)
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.
•Aone-touch PTT function is available. See p. 26 for details.
•“ ” appears on the sub band screen according to the se-
lected 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.
IMPORTANT! (for 50 W transmission):
The IC-2820H is equipped with protection circuits to protect
the power amplier circuit from high temperature. When the
transceiver temperature becomes extremely high, the trans-
ceiver reduces transmit output power to 5 W
(approx.) auto-
matically.
CAUTION: Transmitting without an antenna may damage
the transceiver.
