R WARNING! NEVER connect the transceiver to anAC outlet. This may pose a re hazard or result in an electricshock.

R WARNING! NEVER operate the transceiver whiledriving a vehicle. Safe driving requires your full attentionanything less may result in an accident.

NEVER connect the transceiver to a power source of morethan 16 V DC. This connection will ruin the transceiver.

NEVER connect the transceiver to a power source usingreverse polarity. This connection will ruin the transceiver.

NEVER cut the DC power cable between the DC plug andfuse holder. If an incorrect connection is made after cutting,the transceiver might be damaged.

NEVER place the transceiver where normal operation ofthe vehicle may be hindered or where it could cause bodilyinjury.

NEVER let objects impede the operation of the cooling fan

on the rear panel.DO NOT push the PTT when not actually desiring to transmit.

WORD DEFINITION

R WARNINGPersonal injury, re hazard or electric shockmay occur.

CAUTIONEquipment damage may occur.

NOTEIf disregarded, inconvenience only. No riskof personal injury, re or electric shock.

The IC-2710H Europe versions comply with essential re-quirements of the 89/336/EEC directive for ElectromagneticCompatibility. This compliance is based on conformity withthe ETSI specication prEIS300 684 (EMC product standardfor Commercially Available Amateur Radio Equipment).

DO NOT allow children to play with any radio equipmentcontaining a transmitter.

During mobile operation, DO NOT operate the transceiverwithout running the vehicles engine. When transceiver poweris ON and your vehicles engine is OFF, the vehicles batterywill soon become exhausted.

BE CAREFUL! The transceiver will become hot whenoperating it continuously for long periods.

AVOID using or placing the transceiver in areas with tem-peratures below 10C (+14F) or above +60C (+140F) orin areas subject to direct sunlight, such as the dashboard.

AVOID the use of chemical agents such as benzine or al-cohol when cleaning, as they can damage the transceiversurfaces.

USE Icom microphones only (supplied or optional). Othermanufacturers microphones have different pin assignmentsand may damage the transceiver.

I Using a tuning dial Rotate the desired band s tuning dial to set the frequency.

If VFO mode is not selected, push the same band s [V/MHz] toselect VFO mode.

Frequency changes according to the selected tuning steps.(p. 18)

For the 1 MHz frequency setting, rotate the same band stuning dial after pushing [V/MHz]. Pushing [V/MHz] for 1 sec. starts a scan function. If this happens,

push [V/MHz] again to stop the scan.

D 10 MHz steps

Some versions have 10 MHz tuning steps. For these versionsthe [V/MHz] switch selects 10 MHz, 1 MHz then kHz steps insequence.

I Using [ Y ]/[Z ] switchesPush [ Y ] or [Z ] to set the main band s frequency. If VFO mode is not selected, push [VFO] to select it. Frequency changes according to the selected tuning

steps. (p. 18) Pushing [ Y ] or [Z ] for more than 0.5 sec. activates a

scan. If this happens, push [ Y ] or [Z ] again to stop it.

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

Set the squelch levels. Rotate [SQL] fully counterclockwise in advance. Rotate [SQL] clockwise until the noise just disappears.

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

Set the operating frequency. (pgs. 15 19) 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 settingwhen power is turned OFF or a front panel control is adjusted.

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

Set the audio levels.

Select the desired band. Push [ MONI], then push [ BZ VOL] or

To prevent howling and sensitivity rejection, AVOID set-ting the 430(440) MHz band frequency near a multipleof the 144 MHz band frequency, e.g. setting for

145 MHz and 435 MHz. Push the desired band s tuning dial to select the main band

for transmitting. Set the operating frequency. (pgs. 15 19)

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

$ appears. The S/RF indicator shows the output power selection. The operating frequency, etc. are automatically programmed into

Speak 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. Release [PTT] to return to receive.

I Selecting the output powerThe transceiver has 3 output power levels to suit your oper-ating requirements. Lower output power during short-distancecommunication may reduce interference to other stations andreduces current consumption.

Push the desired band s tuning dial. Push [LOW] one or more times to select the desired out-put power. The output power can be changed while transmitting.

CAUTION: Transmitting without an antenna may dam-age the transceiver.
