Specifications

The type of unit supplied is easily identified as the Linear Power
Unit has a ‘voltage selector switch’ on its base.
Auto-sensing Power Unit
This type of Power Unit automatically copes with various input
voltages:
– 100 to 240V a.c. (~).
Linear Power Unit
This type of Power Unit does not automatically cope with various
input voltages. Instead, the voltage selector switch located on its
base needs to be set for operation on the local voltage as necessary.
There are two settings available:
– ‘110’ for 100 to 120V a.c. (~) supplies.
– ‘240’ for 220 to 240V a.c. (~) supplies.
To change the selection take a screwdriver and, by locating it in the
notches of the voltage selector switch, move it to the correct setting.
Note On earlier models of the Linear Power Unit the voltage selector
switch was located inside the external Power Unit. To gain access to
it remove the screws along the sides of the external Power Unit
and carefully lift off the cover, noting that it does not come
completely apart. The voltage selector switch is located on top of
the transformer.

Proceed as follows:
1 Attach a suitable mains voltage connector to the free end of the

complies with any local regulations. If in any doubt, consult
