INSTRUCTION MANUAL
DUAL BAND FM TRANSCEIVER
iC-2710h
IMPORTANT
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.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
WORD |
DEFINITION |
|
RWARNING |
Personal injury, fire hazard or electric shock |
|
may occur. |
||
|
|
|
CAUTION |
Equipment damage may occur. |
|
NOTE |
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).
CAUTIONS
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 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.
i
DO NOT allow children to play with any radio equipment containing a transmitter.
During mobile operation, DO NOT operate the transceiver 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.
BE CAREFUL! The transceiver will become hot when operating it continuously for long periods.
AVOID using or placing the transceiver in areas with temperatures 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 alcohol 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.

■ Antenna installation
D Antenna location
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.
Trunk-mount Roof-mount antenna 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.

Push [POWER] for 1 sec. to turn power ON.
Push [POWER] for 1 sec.
D Main band
The IC-2710H can receive 144 MHz and 430(440) MHz band signals simultaneously. Function access or frequency changes affect the main band only. In addition, signals can be transmitted on the main band only. Set the desired band as the main band.
Push the desired band’s tuning dial to select the main band.
• “Q” indicates the main band.
Push [BAND] to toggle the main band selection

D VFO and memory modes
The transeiver has 2 normal operating modes: VFO mode and memory mode. You can select VFO mode or memory mode independently on each band.
Push the desired band’s [V/MHz] to select VFO mode when the transceiver is not in VFO mode.
•If VFO mode is already selected, the digits below 100 kHz disappear. In this case, push [V/MHz] again (or push twice depending on version).
VFO mode is selected Indicates memory mode
Push [VFO] to select VFO mode.
VFO • The microphone controls the main band only (or using sub band access; p. 22). Push [BAND] to toggle the main band, then push [VFO], if necessary.
15
■ Lock functions
To prevent accidental frequency changes and unnecessary function access, use the lock function. The transceiver has 2 different lock functions.
D Frequency lock
This function locks the tuning dials and switches electronically and can be used together with the microphone lock function.
Push and hold [(SET)L] until “L” appears in the memory channel readout to activate the function.
•To cancel the function, push and hold [(SET)L] until “L” disappears.
•[PTT], [BAND], [MONI], [MUTE], [VOL] and [SQL] can be used while the frequency lock function is in use. Also, DTMF tones or DTMF memory contents can be transmitted from the microphone.
2 “L”s appear while the frequency lock function is in use.
Push and hold [(VFO)LOCK] for 1 sec. to toggle LOCK the function ON and OFF.

3 SETTING A FREQUENCY
■ 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] to select VFO mode.
•Frequency changes according to the selected tuning steps. (p. 18)
For the 1 MHz frequency setting, rotate the same band’s tuning 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.
The display shows that the 1 MHz tuning step is selected for the VHF band.
D 10 MHz steps
Some versions have 10 MHz tuning steps. For these versions the [V/MHz] switch selects 10 MHz, 1 MHz then kHz steps in sequence.

■ Using [Y]/[Z] switches
Push [Y] or [Z] to set the main band’s frequency.
YZ • 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.
NOTE: 1 MHz steps cannot be used via the [Y]/[Z] switches
17
■ Tuning step selection USING SET MODE
Tuning steps are the minimum frequency change increments when you rotate the tuning dial or push the [Y] or [Z] switches on the microphone. The following tuning steps are available:
• 5 kHz |
• 10 kHz |
• 12.5 kHz |
• 15 kHz |
• 20 kHz |
• 25 kHz |
• 30 kHz |

Push the desired band’s tuning dial.
Push the selected band’s [V/MHz] to select VFO mode if another mode has been selected.
Push the selected band’s [(VOL)SET] one or more times until “tS” appears as shown below.
•Pushing [(SQL)MONI] reverses the order of selection.
