Reset If the unit does not react when pressing the control keys on the front panel it may be reset
to normal operation by switching it off and back on using the AC mains switch in the back.
Lightening strikes During the summer months, malfunctions often occur due to voltage spikes in the power
lines after lightning strikes. Completely unplugging the power cord offers the only effective
protection. Merely switching the unit off does not suffice since voltage spikes are able to arc
over separated contacts.
Fuses The fuses are located inside the unit and should only be changed by a qualified technician.
Care Never clean the housing with a wet cloth or chemical cleaning agent. Always make sure that
no liquid gets into the housing.
