magnetic Fields (OET Bulletin 65)
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-inches) away from the lips and the transceiver is verti-
cal.
RWARNING! NEVER operate the transceiver with
a earphone, headphones 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.
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 will ruin the transceiver.
NEVER connect the transceiver to a power source using
reverse polarity. This will ruin the transceiver.
NEVER expose the transceiver to rain, snow or any liq-
uids. The transceiver may be damaged.
NEVER operate or touch the transceiver with wet hands.
This may result in an electric shock or damage the trans-
ceiver.
DO NOT operate the transceiver near unshielded electri-
cal blasting caps or in an explosive atmosphere.
DO NOT push the PTT when not actually desiring to trans-
mit.
BE CAREFUL! The transceiver will become hot when
operating it continuously for long periods.
DO NOT use or place the transceiver in direct sunlight or
in areas with temperatures below –20°C (–4˚F) or above +60
°C (+140˚F).
Place the unit in a secure place to avoid inadvertent use by
children.
DO NOT use of chemical agents such as benzine or al-
cohol when cleaning, as they can damage the transceiver’s
surfaces.

■Caution
• RDANGER! Use and charge only specified Icom battery
packs with Icom radios. Only Icom battery packs are tested
and approved for use with Icom radios. Using third-party or
counterfeit battery packs may cause smoke, fire, or cause
the battery to burst.
DBattery caution
• RDANGER! DO NOT hammer or otherwise impact the
battery. Do not use the battery if it has been severely im-
pacted or dropped, or if the battery has been subjected to
heavy pressure. Battery damage may not be visible on the
outside of the case. Even if the surface of the battery does
not show cracks or any other damage, the cells inside the
battery may rupture or catch fire.
• RDANGER! NEVER use or leave battery pack in areas
with temperatures above +60˚C (+140˚F). High tempera-
ture buildup in the battery, such as could occur near fires
or stoves, inside a sun heated car, or in direct sunlight
may cause the battery to rupture or catch fire. Excessive
temperatures may also degrade battery performance or
shorten battery life.
• RDANGER! DO NOT expose the battery to rain, snow,
seawater, or any other liquids. Do not charge or use a wet
battery. If the battery gets wet, be sure to wipe it dry before
using. The battery is not waterproof.
• RDANGER! NEVER incinerate an used battery pack
since internal battery gas may cause it to rupture, or may
cause an explosion.
• RDANGER! NEVER solder the battery terminals, or
NEVER modify the battery pack. This may cause heat gen-
eration, and the battery may burst, emit smoke or catch
fire.
• RDANGER! Use the battery only with the transceiver for
which it is specified. Never use a battery with any other
equipment, or for any purpose that is not specified in this
instruction manual.
• RDANGER! If fluid from inside the battery gets in your
eyes, blindness can result. Rinse your eyes with clean
water, without rubbing them, and see a doctor immediately.
• WARNING! Immediately stop using the battery if it emits
an abnormal odor, heats up, or is discolored or deformed. If
any of these conditions occur, contact your Icom dealer or
distributor.
• WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside
the battery.
Misuse of Lithium-Ion batteries may result in the fol-
lowing hazards: smoke, fire, or the battery may rupture.
Misuse can also cause damage to the battery or degra-
dation of battery performance.

• WARNING! NEVER put the battery in a microwave oven,
high-pressure container, or in an induction heating cooker.
This could cause a fire, overheating, or cause the battery
to rupture.
• CAUTION! Always use the battery within the specified tem-
perature range, –20˚C to +60˚C (–4˚F to +140˚F). Using the
battery out of its specified temperature range will reduce
the battery’s performance and battery life.
• CAUTION! Shorter battery life could occur if the battery
is left fully charged, completely discharged, or in an ex-
cessive temperature environment (above +50˚C; +122˚F)
for an extended period of time. If the battery must be left
unused for a long time, it must be detached from the radio
after discharging. You may use the battery until the battery
indicator shows half-capacity, then keep it safely in a cool
dry place with the temperature between –20˚C to +20˚C (–
4˚F to +68˚F).
DCharging caution
• RDANGER! NEVER charge the battery pack in areas with
extremely high temperatures, such as near fires or stoves,
inside a sun heated car, or in direct sunlight. In such en-
vironments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
• WARNING! DO NOT charge or leave the battery in the
battery charger beyond the specified time for charging. If
the battery is not completely charged by the specified time,
stop charging and remove the battery from the battery
charger. Continuing to charge the battery beyond the speci-
fied time limit may cause a fire, overheating, or the battery
may rupture.
• WARNING! NEVER insert the transceiver (battery attached
to the transceiver) into the charger if it is wet or soiled. This
could corrode the battery charger terminals or damage the
charger. The charger is not waterproof.
• CAUTION! DO NOT charge the battery outside of the
specified temperature range: 0˚C to +35˚C (+32˚F to +95˚
F). Icom recommends charging the battery at +20˚C (+68˚
F). The battery may heat up or rupture if charged out of the
specified temperature range. Additionally, battery perform-
ance or battery life may be reduced.

■Regular charging
Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.
DBattery indicators
The indicators show “ ,” “ ” and “ ” in sequence
while charging, and both indicators disappear when com-
pletely charged.
DCharging note
• Be sure to turn the transceiver power OFF.
Otherwise the battery pack will not be charged completely or takes
longer charging time periods.
• External DC power operation becomes possible when
using an optional CP-12L, CP-19R or OPC-254L. The at-
tached battery pack is also charged simultaneously, except
during transmit. (see p. 11 for more details)
• The external DC power supply voltage must be within 10–
16 V to charge the battery pack and operation when using
an optional OPC-254L.

■Rapid charging
The optional BC-177 provides rapid charging of the battery
pack.
• Charging period: approx. 2.5 hours (with BP-256)
DCharging note
• Be sure to turn the transceiver power OFF.
Detach the battery pack from the transceiver then charge
the battery pack by itself, or charge the battery with regu-
lar charging when the transceiver power cannot be turned
OFF.
Otherwise the battery pack will not be charged (charging in-
dicator on the BC-177 blinks orange about 10 sec. after the battery
pack is installed in BC-177).
• The desktop charger, BC-177, can only be charged
BP-256. Other types of rechargeable battery, Ni-Cd or
Ni-MH, cannot be charged.
• If the charging indicator blinks orange, there may be a
problem with the battery pack (or charger). Reinsert the bat-
tery pack or contact your dealer.
• The optional CP-12L and OPC-254L can be used instead
of the supplied AC adapter (BC-123A/E). Connect one of
these to the [DC 13.5V] jack in this case.

■Optional battery case
➥Install 2 uLR6 (AA) size
alkaline batteries into the
optional BP-257 BATTERY
CASE.
• Be sure to observe the cor-
rect polarity.
A built-in step-up convertor in the BP-257 increases the
voltage to 5 V DC.
Approx. 100 mW of output power is possible with the
BP-257 operation. Also, no transmit output power selec-
tion is available.
Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
DBattery information
The batteries may seem to have low capacity when used in
low temperatures such as –10°C (+14°F) or below. Keep the
battery case or pack warm in this case.
DBattery replacement
When the batteries become exhausted, the function display
may blink or have a lower contrast. In these cases, replace
all batteries with new, same brand, alkaline batteries.
■Battery information
DBattery life
The transceiver operates with the BP-256 as follows.
However, when operating in DV mode, operating time may
be shortened by one-half hour.
• VHF band : Approx. 5 hours
• UHF band : Approx. 4.5 hours
(Tx: Rx: Stand-by=1: 1: 8)
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. Oth-
erwise, the battery pack or installed batteries will become
exhausted.
DBattery indicator
The battery indicator, “ ,” appears only when the BP-256
is attached to the transceiver.
The battery indicator does not appear when turning power
ON after the charging is completed without disconnecting
the battery charger or external DC power.
Indication Battery condition
The battery has ample capacity.
The battery is nearing exhaustion. Charging is neces-
sary.

■External DC power operation
An optional cigarette lighter cable (CP-12L or CP-19R; for 12 V
cigarette lighter socket) or external DC power cable (OPC-254L)
can be used for external power operation.
DOperating note
• Power supply range is between 10.0–16.0 V DC.
NEVER CONNECT OVER 16 V DC directly into the [DC IN]
jack of the transceiver.
• BE SURE to use CP-12L,CP-19R or OPC-254L when con-
necting a regulated 12 V DC power supply.
Use an external DC-DC converter to connect the trans-
ceiver through optional CP-12L, CP-19R or OPC-254L to a
24 V DC power source.
• The voltage of the external power supply must be within
10–16 V DC when using either CP-12L, CP-19R or OPC-
254L, otherwise, use the battery pack.
• Up to 5 W (approx.) of maximum output power is provided
with the external DC power operation, however, when the
supplied voltage exceeds 14 V, the built-in protection circuit
activates to reduce the transmit output power to 0.5 W (ap-
prox.).
• Disconnect the power cables from the transceiver when
not using it. Otherwise, the vehicle battery will become ex-
hausted.
• The power save function is deactivated automatically dur-
ing external DC power operation.

■Main band selection
The IC-92A/92AD has two independent operating bands; A
band (VFO A) and B band (VFO B). A band (VFO A) can oper-
ate 0.495 MHz to 999.990 MHz*, and B band (VFO B) can
operate 118 MHz to 174 MHz and 350 MHz to 470 MHz.
*Some frequency ranges are blocked for the USA version by regula-
tion.
NOTE: When in dualwatch mode, transmission is avail-
able from the MAIN band only.
DHow to change the main band
➥Push [MAIN/DUAL] to toggle between A and B band.
➥Push and hold [MAIN/DUAL] for 1 sec. to turn the dual-
watch operation ON and OFF.
• While in dualwatch operation, the display indicates A band in
the upper half and B band in the lower half.
➥During dualwatch operation, push [MAIN/DUAL] to select
A band or B band as the main operating band alternately.
