Troubleshooting

We expect you to achieve superb results with your digital surround controller. If, however, you encounter any problems, either when installing and configuring it, or during operation, please check the following pages for suggested solutions.

If these suggestions fail to cure the problem, please contact your Meridian dealer for further

assistance.

General operating problems

Standby light not lit

•Check that the AC power supply is connected correctly.

•Check that the ON OFF switch on the back panel is in the ON position.

If the light still does not illuminate, check any fuses in your power supply and the fuse in the inlet of the G68. If these are all intact, contact your dealer.

Erratic or unexpected system behaviour

Redo the Auto Configure process as follows:

•Put the whole system into standby.

•Make sure you are operating the MSR+ from a position where all the units can receive the infra-red.

•Press Clear on the MSR+.

•Observe all units responding correctly.

In extreme cases, the memory of the G68 may have been corrupted. If this is suspected perform a full reset; see Resetting the product, page 26.
