Remove the Metal Frame Assembly
(1) Use a small, flat bladed screwdriver to release the cast metal frame assembly from the bottom of the
front casing. This action releases the radio PCB from the MMI PCB.
(2) Gently ease the frame assembly out of the front casing taking care not to damage the two flexi-circuits.
(lift the bottom of the frame so that it just clears the plastic casing, then gently slide the frame away from
the top of the casing until it is released from the casing). Caution: The loudspeaker / microphone flexi-
circuit connects the radio PCB (attached to the metal frame) and the loudspeaker / microphone
assembly (attached to the front casing). The flexi-circuit must be released from the connector on the
radio PCB before the frame can be lifted clear of the front casing. Also ensure that the volume
control/top connector assembly stay retained within the chassis and does not fall out.
(3) Slide out the locking drawer of connector, S6, (on the radio PCB) to release the flexi-circuit. Use a very
small bladed screwdriver.
(4) Remove the flexi-circuit from connector, S6.
(5) Lift the frame away from the front casing. At this stage the radio PCB and metal screen are still attached
to the frame.

Remove the Metal Screen from the Radio PCB and Frame Assembly
(1) Use a small, flat bladed screwdriver to release the seven spring tabs on the metal screen. Note:
Releasing three spring tabs on one side and the one at the top of the metal screen should be sufficient
to remove the metal screen.
(2) Lift the metal screen away from the radio PCB and frame assembly.
