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.
