Should it prove necessary to effect repair of the electronics proceed as

To gain access to the circuit boards remove both lids. These are held
on by six self tapping screws, two in each side and two in the back, and
one M3 countersunk socket screw in the centre of the front panel.
If it is necessary to remove the lower circuit board first remove the
front panel knobs. After removing the four self tapping screws from the
sides of the circuit board it can be eased back and lowered on its flying
leads.
Note that the circuit boards are coated with a protective lacquer. If any
components are changed clean the boards and respray with a suitable
laquer.
When refitting the lower circuit board ensure that the peak LED is cor-
rectly located.
