4 CONNECTING TO POWER
USING BATTERIES
Open the battery compartment and insert 4 size D
batteries (also called UM-1) according to the polar-
ity diagram imprinted on the battery compartment
oor.
Please note the following regarding
battery operation:
• The S350DL 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 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.
USING AC POWER
The S350DL 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
S350DL or one that meets the generic specications
required by this product: output of 6 volts, DC, nega-
tive polarity; plug-tip outer diameter of 5.5 millimeter,
inner diameter of 2.1 millimeter; capable of 300 mil-
liamperes or greater. Contact Etón for the name and
location of a retailer that sells the proper adaptor.
NEVER USE AN ADAPTOR THAT DOES NOT MEET
THESE SPECIFICATIONS, AS IT MAY CAUSE DAMAGE
NOT COVERED BY WARRANTY.
POWERING FROM A CAR OR BOAT 12 VOLT DC
BATTERY SOURCE
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
milliamperes of current. Contact Etón for the name
and location of a retailer that sells the proper con-
verter.
