Fuse replacement
When replacing the fuse, be sure to use one
matching the amperage rating stated on the
original fuse. If the fuse blows, check the
power connection and replace the fuse. If the
fuse blows again after replacement, there may
be an internal malfunction. In such a case,
consult your nearest Sony dealer.
Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as
this could damage the unit.
Cleaning the connH tors
The unit may not function properly if the
connectors between the unit and the front
panel are not clean. In order to prevent this,
detach the front panel (page 8) and clean the
connectors with a cotton swab dipped in
alcohol. Do not apply too much force.
Otherwise, the connectors may be damaged.

shorter, depending on the conditions of use.)
When the battery becomes weak, the range of
