INSTRUCTION MANUAL
144 MHz FM TRANSCEIVER
iT2H
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 com-
pletely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL—This in-
struction manual contains important operating instructions for
the IC-T2H.
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 operate the transceiver with a
headset or other audio accessories at high volume levels.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
WORD DEFINITION
RWARNING
CAUTION
NOTE
Personal injury, fire hazard or electric
shock may occur.
Equipment damage may occur.
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the
volume or discontinue use.
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.
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. Be-
ware that external DC power connections will charge batteries
inside the battery case. This will damage not only the battery
case but also the transceiver.

➃
DO NOT push the PTT when not actually desiring to trans-
mit.
Place unit in a secure place to avoid inadvertent use by children.
DO NOT operate the transceiver near unshielded electri-
cal 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).
The use of non-Icom battery packs/chargers may impair
transceiver performance and invalidate the warranty.
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed Ni-Cd batteries will become exhausted.
For USA only:
Caution: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority to
operate this transceiver under FCC regulations.

BATTERY PACKS
■ Battery pack charging
The supplied BP-194
Ni-Cd batteries* and can be charged approx. 300 times.
Charge the batteries before first operating the transceiver or
when they become exhausted.
If you want to be able to charge the batteries 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 batteries until they become completely exhausted
under normal conditions. We recommend battery charging
just after transmitting becomes impossible.
*Not supplied with some versions.
BATTERY CASE
includes rechargeable
■ About battery packs
D Operating period
Depending on installed battery pack (batteries), the operating
period of the transceiver varies. Refer to p. 39 for operating
period details.
D Battery life
If your batteries seem to have no capacity even after being
fully charged, completely discharge them by leaving the
power ON overnight. Then fully charge them again.
If the batteries still do not retain a charge (or very little), new
batteries must be purchased.
■ Charging precautions
NEVER attempt to charge dry cell/alkaline batteries. This will
cause internal liquid leakage and damage the battery case
and transceiver.
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 (USA only)
The product that you purchased contains a
rechargeable battery. The battery is recyclable. At
the end of its useful life, under various state and
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.

When charging a battery case (pack) attached to the transceiver the power must be OFF.
Charging periods:

20 hours (w/BP-196)
*Not supplied with some versions.
D Rapid charging with the BC-119
The optional BC-119 provides rapid charging of optional
Ni-Cd battery packs (power to the transceiver must be OFF
during charging). The following are additionally required:
• AD-81
• An AC adapter (may be supplied
with the BC-119 depending
on version).

BATTERY PACKS
■ Installing batteries in the
battery case
When using a battery case attached to the transceiver, install
8 AA(R6) size Ni-Cd or alkaline batteries as illustrated below.
➀ Remove the bat-
tery case from the
transceiver.
➁ Install 8 × R6(AA)
size Ni-Cd or alkaline batteries.
• Be sure to observe
the correct polarity.
● NEVER connect DC power to the transceiver when in-
stalling dry cell or alkaline batteries. Such a connection will
damage the transceiver.
● Be careful of battery overcharging. When operating via ex-
ternal DC power, installed batteries are simultaneously
charged.
● Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.

■ Setting a frequency
D Via the keypad
➀ Push [A V] to select VFO mode, if
necessary.
➁ Push 6 digit keys, starting from
the 100 MHz digit, to input a frequency.
• Push the [M] key first to start input
from the 100 kHz digit, if desired.
• When a digit is mistakenly input,
push [ ] and input from the begin-
ning.
•“2” and “7” are acceptable for the 1
kHz digits (depending on the 10 kHz digit).
D Using the [Y]/[Z] keys
Each push increments/decrements the frequency according
to the selected tuning step (see right), except when the 100
kHz or 1 MHz dial select step is selected (see following
page). When a dial select step is selected, each push increments/decrements the frequency either 100 kHz or 1 MHz.
