Troubleshooting and maintenance

Cleaning
When cleaning the surround controller bear in mind that the front
of the unit 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 control
unit.
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 control
unit is completely dry.
To clean the audio and video
connections
The audio and video sockets on the rear of the surround
controller 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
● 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.
