Maintenance
Cleaning
When cleaning the FM tuner bear in mind that the front of the
FM tuner is plastic, and the display panel and lid are glass.
Disconnect the power cord before cleaning the unit.
Note: Do not use abrasive cleaners on any part of the FM tuner.
To clean the case, display panel, and
keypad
● Use a slightly damp cloth.
Ensure that no water is allowed to get inside the case, and do
not reconnect the power until you are certain that the FM tuner
is completely dry.
To clean the audio connections
The audio sockets on the back of the FM tuner are gold-plated
and need no cleaning if gold-plated phono plugs are used.
Otherwise, it is recommended that you unplug and reconnect
the plugs at least once a year. A proprietary contact cleaner can
be used to some advantage.
To change the mains fuse
Fuse
Spare
● Remove the mains connector, and pull out the drawer next to
the power input to access the fuses.
Before replacing a blown fuse, if possible ascertain the cause of
the failure.
The fuse drawer includes a spare fuse. This should be replaced
by one of the same rating.
