To remove lift the main bracket rear slightly and slide the
chassis away from the beznet. Ensure that the interconnecting
leads are released from their purse locks to prevent damage
being caused.

When refitting the chassis ensure that the main bracket is
located in the beznet guide slots before sliding the chassis
forwards. Refit the inter-connecting leads in their respective
purse locks.

Remove the rear cover fixing screws indicated and pull the
rear cover backwards away from the set. Take care when
removing the rear cover not to damage the side control and
speaker cables, [disconnect the side control and speaker

To remove the G1 board release the three clips circled and
ease the board gently away from the support bracket.

To place the chassis in the service position, remove the
SF and MS3 boards from their brackets (see 2-8 and 2-9.),
remove the G1 and  D2 brackets and position on the side of
the main bracket as shown above. Insert the main bracket
firmly into the T-slot located on the left corner of the beznet as
