INSTRUCTION MANUAL
i207H
VHF/UHF FM TRANSCEIVER
This device complies with Part 15 of the FCC rules. Operation is sub-
ject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.

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-207H.

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.

*Some versions are supplied with the HM-96 instead.
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 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 if attached.

■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.

■Microphone connection
The microphone connector is located behind the front panel.
Connect the supplied microphone as follows:
➀Slide the supplied microphone cable connector (and at-
tached microphone) into the microphone jack on the main
body of the transceiver until it clicks into place.
➁To remove the microphone, push the release lever on the
bottom of the microphone cable connector.
■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
at right.
➁Connect a separation
cable between the front
panel and main body
using the supplied screws
as illustrated below.

■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/OFF
Push [PWR] for 1 sec. to turn power ON or OFF.
DOperating band
The IC-207H can receive/transmit on the 144 MHz and
430(440) MHz bands, or receive only on the avionics band
(USA version only).
Push [BAND] one or more times to select the desired operat-
ing band.
•The frequency changes to indicate the selected band.
•The operating band cannot be changed unless you are in VFO
mode (see right).
Push [BAND] one or more times to select the de-
sired operating band.
DVFO and memory modes
The transceiver has 2 normal operating modes: VFO mode
and memory mode.
Push [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.
Push [PWR] for 1 sec.
