■

Receiving

The IC-2710H can receive 144 MHz and 430(440) MHz band
signals simultaneously.

➀

Push [POWER] for 1 sec. to turn power ON.

➁

Set the audio levels.

➥

Push [

(SQL)

MONI] to open the squelch.

➥

Rotate the [VOL] control to adjust the audio output level.

➥

Push [

(SQL)

MONI] again to close the squelch.

➂

Set the squelch levels.

➥

Rotate [SQL] fully counterclockwise in advance.

➥

Rotate [SQL] clockwise until the noise just disappears.

➥

When interference is received, rotate [SQL] clockwise
again for attenuator operation.

➃

Set the operating frequency. (pgs. 15–19)

➄

When receiving a signal on the set frequency, squelch
opens and the transceiver emits audio.

• “BUSY” appears and the S/RF indicator shows the relative signal

strength on the received band.

When receiving a signal on VHF.

The volume and squelch levels can be adjusted via the mi-
crophone. However, levels return to the front panel setting
when power is turned OFF or a front panel control is adjusted.

Ä

Push [POWER] on the transceiver for 1 sec. to
turn power ON.

Å

Set the audio levels.

➥

Select the desired band.

➥

Push [

➀

MONI], then push [

BZ

VOL] or

[

IY

VOL] to adjust the audio level.

➥

Push [

➀

MONI] again to close the squelch.

Ç

Set the squelch level using [

AZ

SQL] or

[

HY

SQL], if desired.

É

Set the operating frequency. (pgs. 15–19)

✔

CONVENIENT

RF attenuator: 

The transceiver has an RF attenuator related

to the [SQL] setting. The attenuator is automatically activated
when [SQL] is rotated further than the 12 o’clock position.
Approx. 10 dB attenuation is obtained at full rotation.
