The 1968 MkII unit will be supplied with a power cable suitable for domestic power outlets in your country. For your own

safety, it is important that you use this cable to connect to the mains supply earth. The cable must not be tampered with

or modified.

The power supply socket has an integral fuse drawer containing the power fuse of the same value, to suit the mains

voltage for which the unit has been supplied. Removal of the drawer is only possible with the power cord removed. The

fuse should never blow under normal operation. If the fuse is suspected of having blown, then a fault will have occurred

and this fault condition should be inspected by a qualified service engineer. When replacing the fuse, always comply with

the Safety Instructions.

If the unit is to be used with a mains input operating

voltage different to that for which the unit is supplied, the

following procedure must be carried out by a technically

competent person, (see following diagrams)

1: Disconnect the unit from the mains.

2: Using a number 1 size pozidrive screwdriver,

remove the seven self -tapping screws that retain the

top cover.Two screws are found along each side; two

along the top edge at the rear; and the upper central

screw on the front facia panel.

3: Slide the voltage change-over switch (SW8) until

the correct (or nearest) mains input voltage is visible

on the switch actuator.
