PRE-OPERATION
li Battery pack charging
Charge the battery pack before first operating the trans-
ceiver and when the low battery indicator appears.
li Battery pack precautions
NEVER throw a battery pack into a fire.
NEVER expose the battery pack to water.
NEVER short the metal terminals of a battery pack.
DO NOT attempt to charge a fully charged battery pack.
DO NOT discharge a battery pack completely.
AVOID overcharging. Disconnect the wall charger or power
cable within 48 hrs.
Charging may not occur in extreme cold (under 0°C;
+ 32°F ) or extreme heat (over + 40°C; + 104°F ).
i About the battery pack
©} Operating period
Operating period of the CM-166 (12 V, 600 mA) is approx.
5 hours.
CONDITION: 5% Tx / 5% Rx / 90% Standby (squelched).
The operating period is an estimate and varies depending
on temperature, etc.
© Battery memory effect
Full charge capacity may become lower when repeatedly
recharging after only partial discharging. If this occurs,
discharge almost completely through normal use before
recharging.
} Battery pack life
When the operating period becomes extremely short even
after charging the battery pack fully, a new battery pack is
needed.
Recycling information (U.S.A. only)
The product that you have 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.

2 PRE-OPERATION
i External power source
connection
An optional CP-17L CIGARETTE LIGHTER CABLE is available
to operate the IC-A22 with a 12 V cigarette lighter socket.
The attached Ni-Cd battery pack is charged in approx. 15
hrs. simultaneously. While connecting an external power
source, DO NOT connect the wall charger to the CM-166.
The OPC-515L DC POWER CABLE with a 12 V DC power
supply can be used instead of the CP-17L.
Wf Alkaline battery installation
An optional CM-167 BATTERY CASE is available. Install ten
alkaline batteries as follows.
@ Push and hold the battery release button upwards, then
slide the battery case to the right with the transceiver
facing you. (Fig. 1)
@® Open the battery case. (Fig. 2)
@ Install 10 alkaline batteries. (Fig. 3)
* Pay attention to the polarities,

lM Accessory attachment
© Antenna
Connect the supplied flexible antenna into the antenna
connector and rotate clockwise.
Y NOTE: The supplied flexible antenna is optimized for
Z communication frequencies. For improved reception of
Y VOR signals, you can connect it directly to the aircraft's
Z NAV antenna.
CAUTION:
Transmitting without the
antenna may damage
the transceiver.
