8 Troubleshooting
In the following we list a few common problems that may occur during operation. We give you
some suggestions for easy troubleshooting:
Symptom Remedy
The unit does not work, no sound,
no indicator lights up.
Check the mains connection and the main fuse.
Disconnect the device from the mains power supply.
Open the fuse holder beneath the IEC chassis connector
(21) and check the fuse. If it's blown, replace it by a new
fuse with same specifications. Refit the fuse holder cap
and reconnect the device to the mains power supply.
