This requires a DC converter that converts the 12
volt DC source to the 6 volts required by the
radio. The output of such an adaptor is 6 volts,
DC, negative polarity. The plug-tip must have an
outer diameter of 5.5 millimeter and an inner
diameter of 2.1 millimeter.
The plug-tip is plugged into the radio’s DC jack. It
must be capable of handling at least 200 mil-
liamperes of current. Contact Etón for the name
and location of a retailer that sells the proper
converter.

CONNECTING TO POWER
U S I N G B AT T E R I E S
Open the battery compartment and insert 4 size D
batteries (also called UM-1) according to the
polarity diagram imprinted on the battery com-
partment floor.
Please note the following regarding battery oper-
ation:
• The S-350 has a battery power indicator in
the LCD. Fresh batteries will show a full power
level of six bars. If the indicator shows less
than two bars or the sound becomes week
and distorted, 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.
U S I N G A C P O W E R
The S350 is supplied with an AC adaptor that
converts AC voltage to the DC voltage used by
the radio. Only use the adaptor that is supplied
with the S350 or one that meets the generic spec-
ifications required by this product: output of 6
volts, DC, negative polarity; plug-tip outer diame-
ter of 5.5 millimeter, inner diameter of 2.1 mil-
limeter; capable of 300 milliamperes or greater.
Contact Etón for the name and location of a
retailer that sells the proper adaptor.
