(1) REMOVING THE PLATES

In the event of servicing being required to the solder side of the D Board printed
circuit, the bottom plates fitted to the main chassis bracket require to be removed.

For safety reasons, on no account should the plates be removed
and not refitted after servicing.

(2) REFITTING THE PLATES

original location.
The plates are identified by markings A-B-C-D-E on their top side.
1. Identify the plate by locating its marking.
2. Turn the plate over noting where the marking is located.
3. Locate the corresponding marking indicated on the main chassis bracket. See Fig 2.
