INSTRUCTION MANUAL

DUAL BAND FM TRANSCEIVER

iC- 2710h

IMPORTANT

CAUTIONS

READ ALL INSTRUCTIONS carefully and completely before using the transceiver.

SAVE THIS INSTRUCTION MANUAL—This instruction manual contains important operating instructions for the IC-2710H.

RWARNING! NEVER connect the transceiver to an

AC outlet. This may pose a ﬁre hazard or result in an electric shock.

RWARNING! NEVER operate the transceiver while

driving a vehicle. Safe driving requires your full attention— anything less may result in an accident.

NEVER connect the transceiver to a power source of more

EXPLICIT DEFINITIONS

The explicit deﬁnitions below apply to this instruction manual.

WORD DEFINITION

RWARNING

CAUTION

NOTE

Personal injury, ﬁre hazard or electric shock may occur.

Equipment damage may occur.

If disregarded, inconvenience only. No risk of personal injury, ﬁre or electric shock.

The IC-2710H Europe versions comply with essential requirements of the 89/336/EEC directive for Electromagnetic Compatibility. This compliance is based on conformity with the ETSI speciﬁcation prEIS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment).

than 16 V DC. This connection will ruin the transceiver.

NEVER connect the transceiver to a power source using

reverse polarity. This connection will ruin the transceiver.

NEVER cut the DC power cable between the DC plug and

fuse holder. If an incorrect connection is made after cutting, the transceiver might be damaged.

NEVER place the transceiver where normal operation of

the vehicle may be hindered or where it could cause bodily injury.

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.

DO NOT allow children to play with any radio equipment

containing a transmitter.

UNPACKING

During mobile operation, without running the vehicle’s engine. When transceiver power is ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted.

DO NOT operate the transceiver

BE CAREFUL! The transceiver will become hot when

operating it continuously for long periods.

AVOID using or placing the transceiver in areas with tem-

peratures below –10°C (+14°F) or above +60°C (+140°F) or in 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 transceiver surfaces.

USE Icom microphones only (supplied or optional). Other

manufacturer’s microphones have different pin assignments and may damage the transceiver.

■ Location

Select a location which can support the weight of the transceiver and does not interfere with driving in any way. We recommend the locations shown in the diagram below.

NEVER place the transceiver or remote controller where

normal operation of the vehicle may be hindered or where it could cause bodily injury.

NEVER place the transceiver or remote controller where

air bag deployment may be obstructed.

DO NOT place the transceiver or remote controller where

hot or cold air blows directly onto it.

AVOID placing the transceiver or remote controller in di-

rect sunlight.

• EXAMPLE INSTALLATION LOCATIONS

■ Single body installation

➀ Drill 4 holes where the mounting bracket is to be installed.

• Approx. 5.5–6 mm (3⁄16 in) when using nuts; approx. 2–3 mm (1⁄16 in) when using self-tapping screws.

➁ Insert the supplied screws, nuts and washers through the

mounting bracket and tighten.

To obtain maximum performance from the transceiver, select a high-quality antenna and mount it in a good location. A nonradial antenna should be used when using a magnetic mount.

Roof-mount antenna (Drill a hole or use a magnetic mount.)

Gutter-mount antenna

D Antenna splitter

You can use a dual band antenna because a duplexer is installed in the transceiver. However, an external duplexer must be connected when using a separate antenna for each band.

Trunk-mount antenna

memory

➀ Select the call channel by pushing the desired band’s

RECEIVE ACCEPT AND INHIBIT

Code channels 1–5 can store the transmit codes for personal calls to other individuals and the group codes for group calls.

The group codes should be programmed as “receive accept” (“” disappears) to receive all calls from group members.

If transmit codes are not programmed as “receive inhibit,” the transceiver accepts calls directed to other individuals and your answer back may confuse other members in your group—this is not a selective calling system. Therefore, transmit codes should be programmed as “receive inhibit” (“” appears) so the transceiver rejects calls directed to other individuals.

➄ Push [POWER] momentarily to exit initial set mode.

USING

■ Time-out timer

To prevent accidental prolonged transmission with the onetouch PTT function, etc., the transceiver has a time-out timer. This timer cuts a transmission OFF after 3, 5, 15 or 30 min. of continuous transmission. This timer can be cancelled (default).

Approx. 10 sec. before the time-out timer passes, the transceiver emits a beep tone as a warning.

OTHER FUNCTIONS

USING

■ Auto power-off

The auto power-off function conveniently turns the transceiver power OFF after a preset time in which no operations are performed. In this way, when you forget to turn the power OFF, the transceiver automatically turns itself OFF, thereby conserving battery power.

The time can be set to 30 min., 1 hr., 2 hr. or turned OFF. The selected time is retained even when the transceiver is turned OFF via the auto power-off function. To cancel the function, select “oF” in step ➃ below.

➀ Push and hold [VOL(SET)D] (right side) until “d-1”–“d4” ap-

pears as shown below.

➁ Rotate the tuning dial (right side) to set the desired inten-

sity.

• Intensity can be set from “d1” (dark) to “d4” (bright).

➂ Push [VOL(SET)

D] to return to normal operation.

■ Demonstration display

A demonstration function is available at power ON. This function gives you a quick visual introduction to the function display indicators.

➀ While pushing either tuning dial, push [POWER] to turn

power ON.

• The transceiver cycles through a visual tour of the function display indicators.

➁ Push any switch to exit demonstration mode and enter the

normal operating condition temporarily.

NOTE: The transceiver automatically returns to demonstration mode after 2 min. in which no operations are performed. To deactivate the demonstration display permanently, perform step ➀ again.

grammed.

• The frequency lock function is activated.

• Priority watch is paused on the watching fre-

quency.

If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center.

• Check the connector pins.

• Reconnect the power cable observing the proper

polarity. Replace the fuse, if damaged.

• Check the cause, then replace the fuse.

• Rotate [VOL] clockwise.

• Set the squelch level to the threshold.

• Turn the appropriate function OFF.

• Check, and if necessary, replace the feedline or

solder the antenna connector again.

• Set to simplex.

• Turn ON the optional code squelch (UT-49) or

optional tone squelch (UT-104 ).

• Correct the offset frequency.

• Correct the subaudible tone frequency.

• Turn the function OFF.

MAINTENANCE

■ Fuse replacement

If the fuse blows or the transceiver stops functioning, ﬁnd the source of the problem if possible, and replace the damaged fuse with a new, rated one (FGB 20 A) as shown in the diagram below.

■ Partial resetting

If you want to initialize the operating conditions without clearing the memory contents, etc., a partial reset function is available for the transceiver. The partial reset can be performed independently for each band.

While pushing either left or right, or both [V/MHz] switches, turn power ON to partially reset the transceiver.

➧ Initialized settings: VFO frequency, SET mode settings. ➧ Retained settings: Memory channels, call channels, offset

freq. in memory/call, DTMF memory, pager and code squelch settings, initial SET mode settings.

■ Resetting the transceiver

The function display may occasionally display erroneous information, (e.g. when first applying power). This may be caused externally by static electricity or other factors.

If this problem occurs, turn power OFF. After waiting a few seconds, turn power ON again. If the problem persists, perform the following procedure.

Partial resetting is alternatively available. See previous section for details.

CAUTION: Resetting the transceiver CLEARS all

memory information, and initializes all values in the transceiver.

➀ Push [POWER] to turn power OFF. ➁ While pushing both left and right [S.MW] switches, turn

power ON.

• All LCD segments appear momentarily, the initial display appears and the transceiver is reset.
