In the unlikely event of the fuse blowing, the retainer and mains cable must be removed to gain access to the
fuse carrier.
The carrier can be removed with a fingernail or tip of a screwdriver. A spare fuse is provided in the carrier.
Replacement fuses must be 20mm cartridge fuses, of the correct rating : F50mA
Cleaning
The front panel membrane conceals and protects switches and LEDs. It may be wiped clean using a damp cloth.
Be sure to disconnect the unit from the mains before cleaning, and do not use any abrasive cleaners or organic
solvents.
Periodic testing:
Check the mains lead and plugs at both ends for any damage.
Periodically check the earth bonding and insulation, by performing a Portable Appliance Test (
PAT
). Most
schools and local authorities have a regular schedule for such testing.
Check that the fuse in the mains plug (5A recommended) and the two fuses (active and spare) in the IEC socket
on the back panel are all of the correct rating.
