5. Cleaning and Maintenance
1. Disconnect the device from the mains prior to maintenance activities.
2. The power supply cables must not show any damage. Have a qualified technician maintain
the device.
3. Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
4. There are no user-serviceable parts, apart from the fuse. Contact your dealer for spare parts if
necessary.
5. Store the device in a dry, well-ventilated, dust-free room.
Replacing the Fuse
1
Only replace the fuse by a fuse of the same type and rating.
2
Before replacing the fuse, unplug the mains lead.
3
Wedge the fuse holder out of its housing with a flat-head screwdriver.
4
Remove the damaged fuse from its holder and replace with the exact same type of fuse.
5
Insert the fuse holder back in its place and reconnect power.
