Open the battery compartment and insert 4 size D
batteries (also called UM-1) according to the
polarity diagram imprinted on the battery compartment floor.
Please note the following regarding battery operation:
• The S-350 has a battery power indicator in
the LCD. Fresh batteries will show a full power
level of three bars. If the indicator shows only
one bar or the sound becomes week and dis-
torted, replace the batteries.
• The radio will turn off automatically if the
batteries become too weak.
• Check the batteries periodically for leakage.
As a precaution, remove the batteries to
prevent possible leakage if it is to be stored
for long periods without use.
• Turn off the radio while replacing the batteries.
USI N G A C P O W ER
