RWARNING! NEVER connect the receiver via the
OPC-254L to an AC outlet. This may pose a fire hazard or re-
sult in an electric shock.
RWARNING! NEVER operate the receiver while dri-
ving a vehicle. Safe driving requires your full attention— any-
thing less may result in an accident.
NEVER connect the receiver to a power source of more
than 14 V DC. This will damage the receiver.
NEVER connect the receiver to a power source using re-
verse polarity. This will damage the receiver.
NEVER cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting,
the receiver may be damaged.
DO NOT leave the main unit powered ON and connected
to a vehicle’s electrical system. The main unit draws approx.
550 mA. This will eventually drain the vehicle’s battery.
NEVER expose the receiver to rain, snow or any liquids.
The receiver may be damaged.
NEVERoperate or touch the receiver with wet hands. This
may result in an electric shock or damage the receiver.
NEVER place the receiver where normal operation of the
vehicle may be hindered or where it could cause bodily injury.
NEVERlet objects impede the operation of the cooling fan
on the rear panel.
AVOID using or placing the receiver in direct sunlight or in
areas with temperatures below –10°C (+14°F) or above
+60°C (+140°F).
BE CAREFUL! The receiver will become hot when op-
erating it continuously for long periods.
AVOID setting the receiver in a place without adequate
ventilation. Heat dissipation may be affected, and the receiver
may be damaged.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they can damage the receiver’s sur-
faces.
For U.S.A. only
CAUTION: Changes or modifications to this device, not ex-
pressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
