contact.

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.

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 (page7)
and clean the connectors with a cotton swab. Do not

or with any metal device.
