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.

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.

eDATA JACK [DATA]
6-pin mini DIN jack to connect a TNC, etc. for packet op-
eration.
NOTE: The connection between this jack and the TNC
differs depending on whether 1200 bps or 9600 bps op-
eration is chosen in initial set mode (p. 63). See right
for pin assignments.

PTT terminal for packet operation only. Connect ground to
transmit data.
rDATA OUT
Data out terminal for 9600 bps operation only.
tAF OUT

ySQ (squelch out)
Becomes high (+5V) when the transceiver receives a sig-
nal which opens the squelch.
•To avoid unnecessary TNC transmission, connect squelch to the
TNC to inhibit transmission when receiving signals.
•Keep audio output at a normal level, otherwise a “SQ”signal will
not be output.
