DUAL BAND FM TRANSCEIVER
IC-2710H.qxd 02.2.8 16:55 Page A (1,1)

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
IMPORTANT
READ ALL INSTRUCTIONS carefully and completely before
using the transceiver.
SAVE THIS INSTRUCTION MANUAL—This instruction man-
ual 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 re-
quirements 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).

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 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 trans-
ceiver and does not interfere with driving in any way. We rec-
ommend the locations shown in the diagram below.
■Single body installation
➀Drill 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.
➁Insert the supplied screws, nuts and washers through the
mounting bracket and tighten.
➂Adjust the angle for the clearest view of the function dis-
play.
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.

as shown below.
➁Connect the supplied microphone to the microphone con-
nector.
➂Reattach the remote controller to the main body.
➃To remove the microphone, push the release button as
above.
■Separate installation
Using an optional OPC-600/601 SEPARATION CABLE
, the front
panel can be separated from the main body, doubling as a re-
mote controller.
➀Detach the front panel as shown at left.
➁Connect a separation cable to the front panel and to the
main body using the supplied screws as illustrated below.

■Optional MB-58 installation
The optional MB-58 REMOTE CONTROLLER BRACKET is avail-
able for separate installation.
➀Drill 2 or 4 holes where the bracket or mounting base is to
be installed, respectively.
•Approx. 4 mm (1⁄8in) when using nuts; approx. 1–2 mm (1⁄16 in)
when using self-tapping screws.
➁Insert the supplied screws, bolts and washers through the
mounting base and tighten.
➂Adjust the angle for the clearest view of the function dis-
play and tighten 2 screws when the mounting base is used.

■Battery connection ■DC power supply connection
Use a 13.8 V DC power supply with more than 12 A capabil-
ity. An optional IC-PS30
DC POWER SUPPLY
is available for
using the transceiver with a DC power supply in your home.
Make sure the ground terminal of the DC power supply is
grounded.
NEVER connect the transceiver directly to a 24 V battery.
DO NOT use the cigarette lighter socket for power con-
nections.
Attach a rubber grommet when passing the DC power
cable through a metal plate to prevent short circuits.

■Antenna installation
DAntenna location
To obtain maximum performance from the transceiver, select
a high-quality antenna and mount it in a good location. A non-
radial antenna should be used when using a magnetic mount.
DAntenna splitter
You can use a dual band antenna because a duplexer is in-
stalled in the transceiver. However, an external duplexer must
be connected when using a separate antenna for each band.
DAntenna connector
The antenna uses a PL-259 connector.

■Preparation
DTurning power ON
Push [POWER] for 1 sec. to turn power ON.
DMain 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
between the 144 and 430(440) MHz bands.
DVFO 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 disap-
pear. In this case, push [V/MHz] again (or push twice depending on
version).
Push [VFO] to select VFO mode.
•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.
Push [POWER] for 1 sec.
