Operating Notes - Icom IC-4SA: IC-4SE: Instruction Manual

IMPORTANT
READ ALL INSTRUCTIONS carefully and com-
pletely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL — This
instruction manual contains important safety and
operating instructions for the IC-4SA/SE.
OPERATING NOTES
BE CAREFUL! When transmitting for a long time
with high output power, the rear panel may
become hot.
When using the BP-90 (battery case) or BP-81
(smallest battery pack), we recommend operating
with low output power. Battery power will be
reduced quickly if the transceiver is operated
continuously using high output power.
CAUTIONS
NEVER connect the transceiver via the [DC
13.8 V] jack to an AC outlet or to a power source
of more than 16 V DC. These connections will
ruin the transceiver.
NEVER connect the transceiver to a power source
using reverse polarity. This connection will harm
internal transceiver circuitry.
NEVER allow children to touch the transceiver.
NEVER use a non-recommended charger for
charging. Suggested chargers are described on p. 3.
AVOID using or placing the transceiver in areas
with temperatures below —10°C (+14°F) or over
+60°C (+140°F).
AVOID placing the transceiver in direct sunlight.
