e Operate the unit only on 6 V DC.
For battery operation, use four size AA (R6) batteries.
For AC operation, use the AC power adaptor supplied with this
unit; do not use any other type.
For car battery operation, use the car battery cord recommended
for this unit; do not use any other type.
e Do not leave the unit in a location near heat sources, or in a place
subject to direct sunlight, excessive dust, or mechanical shock.
e Use the unit within a temperature range of 0°C to 40°C (32°F to
104°F). If it is used in temperatures outside this range, there may
be trouble with the frequency and clock display. If it is used in
temperatures lower than this range, the displayed numbers may
change very slowly. This is not an internal malfunction. The display
will recover when the unit is used within the recommended
temperature.
ə Should any solid object or liquid fall into the unit, remove the
batteries, and have the unit checked by qualified personnel before
operating it any further.
« Since a strong magnet is used for the speaker, keep personal
credit cards using magnetic coding or spring-wound watches away
from the unit to prevent them from possible damage caused by the
magnet.
e Reception around 1.8 MHz and 3.6 MHz may be difficult because
of internal spurious signals generated by the built-in oscillators.
e When the casing becomes soiled, clean it with a soft cloth
dampened with mild detergent solution. Never use abrasive
cleansers or chemical solvents, as they may mar the casing.
If you have any question or problem concerning your unit that is not
covered in this manual, please consult the nearest Sony dealer.
