FOREWORD
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.
CAUTIONS
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL This in-
struction manual contains important operating instructions for the IC-A4.
EXPLICIT DEFINITIONS
The explicit definitions below apply to this instruction manual.
FCC caution: Changes or modifications to this transceiver, not
expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations.
R WARNING! 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 away from the lips and the transceiver is vertical.
R WARNING! NEVER 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 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.

qw etr
DO NOT push the PTT when not actually desiring to trans-
mit.
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 or above +60°C.
Place unit in a secure place to avoid inadvertent use by chil­dren.
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 dry cell batteries will become ex­hausted.
NOTE: Optional functions vary with transceiver version.
In this manual, optional functions are indicated by

BATTERY PACKS
Charging precautions
NEVER attempt to charge dry cell bat-
teries. 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).
When using BC-119: If the charge indicator flashes orange, vehicle bat­tery voltage is low and charging is not possible. Check the vehicle bat­tery voltage in this case. If the charge indicator flashes red, there may be a problem with the battery pack (or charger). Re-insert the bat­tery pack or contact your dealer.
Battery pack charging
The BP-195 or BP-196 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.
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 pe-
riod should be less than 48 hours.
2.Use the battery until it becomes al-
most completely exhausted under normal conditions. We recommend battery charging just after transmitting becomes impossible.

D
Rapid charging with the BC-119
The optional BC-119 provides rapid charging of battery packs. One AD-81 and an AC adapter (may be supplied with the BC-119 depending on version) are additionally required.

About the battery pack
D Operating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Refer to OPTIONS for battery pack
specications.
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.
D Recycling information (U.S.A only)
The product that you have purchased may contain a rechargeable battery. The battery is recyclable. At the end of its 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.
Installing batteries in the battery case
When using a battery case, install 8 AA (R6) size Ni-Cd or al­kaline batteries as illustrated below.
q Remove the bat-
tery case from the transceiver.
w Install 8 × AA (R6)
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 ex­ternal DC power, installed batteries are simultaneously charged.
Keep battery contacts clean. It’s a good idea to clean bat- tery terminals once a week.
