start of this manual.

Ensure all on/off power switches are set to their 'OFF' positions and the
mains lead has been removed from the unit's power socket.

Using a small thin-bladed screwdriver, remove the fuse retainer cap.
The cap has a spring-loaded locking feature which needs to be
disengaged by pushing the cap inwards whilst turning it anticlockwise.
The fuse carrier and fuse can then be withdrawn from its socket.

Renew the protection fuse with a fuse of the same type and rating.
