INSTRUCTION MANUAL
DUAL BAND FM TRANSCEIVER
iT7H
This device complies with Part 15 of the FCC rules. Operation is subject 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.
IMPORTANT
CAUTIONS
READ ALL INSTRUCTIONS carefully and completely before
using the transceiver.
RWARNING! NEVER hold the transceiver so that the

antenna is very close to, or touching exposed parts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
(2 to 4 in) away from the lips and the transceiver is vertical.
RWARNING! NEVER
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
WORD
DEFINITION
Personal injury, fire hazard or electric shock
RWARNING may occur.
CAUTION
NOTE
NEVER connect the transceiver to an AC outlet or to a
power source of more than 16 V DC. Such a connection will
damage the transceiver.
Equipment damage may occur.
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
The IC-T7H complies with essential requirements of the
89/336/EEC directive for Electromagnetic Compatibility.
This compliance is based on conformity with the ETSI
specification ETS300 684 (EMC product standard for
Commercially Available Amateur Radio Equipment).
operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the
volume level or discontinue use.
NEVER
connect the transceiver to a power source that is DC
fused at more than 5 A. Accidental reverse connection will be
protected by this fuse, higher fuse values will not give any protection against such accidents and the transceiver will be ruined.
NEVER attempt to charge alkaline or dry cell batteries. Beware that external DC power connections will charge batteries
inside the battery case. This will damage not only the battery
case but also the transceiver.
UNPACKING
DO NOT push the PTT when not actually desiring to transmit.
DO NOT operate the transceiver near unshielded electrical
blasting caps or in an explosive atmosphere.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –10°C (+14°F) or above
+60°C (+140°F).
Place unit in a secure place to avoid inadvertent use by children.

BATTERY PACKS AND ACCESSORIES
■ Battery pack charging
■ About the battery pack
The supplied* BP-180 BATTERY PACK includes rechargeable
Ni-Cd batteries and can be charged approx. 300 times.
Charge the battery pack before first operating the transceiver
or when the battery pack becomes exhausted.
D Operating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Refer to p. 28 for battery pack specifications.
*Optional for versions which come with the BP-170 BATTERY CASE.
If you want to be able to charge the battery pack more than
300 times, the following points should be observed:
1. Avoid overcharging. The charging period should be less
than 48 hours.
2. Use the battery until it becomes almost completely exhausted under normal conditions. We recommend battery
charging just after transmitting becomes impossible.
D Battery pack life
If your battery pack seems to have no capacity even after
being fully charged, completely discharge it by leaving the
power ON overnight. Then, fully charge the battery pack
again.
If the battery pack still does not retain a charge (or very little),
a new battery pack must be purchased.
■ Charging precautions
NEVER connect two or more chargers at the same time.
Charging may not occur under temperatures of 10°C (50°F)
or over temperatures of 40°C (104°F).
Recycling information (U.S.A. only)

local laws, it may be illegal to dispose of this battery into the
municipal waste stream. Call 1-800-8-BATTERY for battery
recycling options in your area or contact your dealer.

NEVER attempt to charge dry cell batteries. This will cause
internal liquid leakage and damage the battery case and

BASIC OPERATION
■ Repeater operation
D Tone information
D General
Some repeaters require a tone to be accessed. In this case,
precede step ➃ at left with the required tone.
When using a repeater, the transmit frequency is shifted from
the receive frequency by the offset frequency. It is convenient
to program repeater information into memory channels
(p. 15).

• “– DUP” or “DUP” appears to indicate the transmit frequency for
minus shift or plus shift, respectively.
• When the auto repeater function is in use (U.S.A. version only)
this selection and step ➂ are not necessary (p. 24).
➂ Push [TONE] to activate the subaudible tone encoder, according to repeater requirements.
• “T” appears.
• Refer to the table of tone frequencies on the following page.
➃ Push and hold [PTT] to transmit.
1750 Hz TONE (Europe and Italy versions only)
While pushing [PTT], push and hold [TONE] for 1 to 2 sec. to
transmit a 1750 Hz tone signal.
✔ CONVENIENT
Tone scan function: When you don’t know the subaudible
tone used for a repeater, the tone scan is convenient for detecting the tone frequency.
Push and hold [T SCAN?] to activate. See p. 22 for more information.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If “OFF” appears, check the offset frequency (p. 14).

ADVANCED FUNCTIONS
■ Memory/call channels
The transceiver has 70 memory channels (60 regular, 4 pairs
of scan edge channels for mixed bands and 1 call channel for
each band). Note that memory channels are not grouped according to band. In other words, a given memory channel can
be programmed with either a VHF frequency or a UHF frequency. This is not the case with call channels. Call channels
are band specific.
The following can be programmed into memory/call channels:
• Operating frequency

ADVANCED FUNCTIONS
D Pocket beep operation
D Tone scan
This function uses subaudible tones for calling and can be
used as a “common pager” to inform you that someone has
called while you were away from the transceiver.
The transceiver can detect the subaudible tone frequency in a
received signal. By monitoring a signal, such as that being
transmitted on a repeater input frequency, you can determine
the tone frequency required to access the repeater.
➀ Set the operating frequency.
➁ Set the desired subaudible tone (same as that used for
tone squelch operation, “CT”) in set mode.
• See p. 21 for programming.
➂ Push [TONE] two times until “TSQLS” appears.
➃ When a signal with a matched tone is received, the transceiver emits beep tones for 30 sec. and flashes “S.”
➄ Push [PTT] to answer or push [VFO] to stop the beeps and
flashing.
• Tone squelch is automatically selected.
D Calling a waiting station using pocket beep
A subaudible tone matched with the station’s tone frequency
is necessary. Use the tone squelch on p. 21 or a subaudible
tone encoder.
➀ Set the desired frequency or memory channel to be
checked for a tone frequency.
➁ Push [T SCAN] for 1 sec. to start the tone scan.
• To change the scanning direction, rotate [DIAL].
➂ When the tone frequency is decoded, the set mode contents are programmed with the tone frequency.
• The decoded tone frequency is used for the tone encoder or tone
encoder/decoder, depending on the the tone squelch ON/OFF
setting.
• “CT” or “rT” appears during tone scan when the tone squelch is in
use or not, respectively.
➃ Push [VFO] to stop the scan.
