7.2. Dis-Assembling the Unit

A. Ensure that the unit is switched off before removing

the rear panel which slides out.

Note: The plastic cover retaining clip will need to be

removed prior to sliding cover off, refit when

reassembled.

B. Remove the cap on the multi-turn control knob by levering it off

with a fine bladed screwdriver or similar tool.

C. Remove the collet nut (inside the knob). Use a suitable split

head screwdriver or small long nosed pliers.

D. Remove the knob and then the hexagon nut below it, use

the correct sized spanner or pliers. Take care not to

damage the front panel label.

E. Gently press on the shaft of the multi-turn control to

release the printed circuit assembly and battery from the

case. Do not attempt to remove it completely - leave the

case sitting vertical and the assembly flat horizontal.
