3.7.7 Option Board Installation

1. With the keypad retainer removed the keypad backer board can be removed without the use of
tools.
2. Remove the jumper flex from the connector on the keypad/PassPort option board. Notice the
orientation of the flex to the connector. Arrows on the jumper flex point to the correct way of
inserting the flex into the connector.
3. Discard the keypad backer board.
NOTE The "breakaway" tab at the top of the keypad/PassPort option board contains an
extra row of keys and is used to accommodate other radio models.
4. Break-off and discard the keypad/PassPort option board tab, taking care not to damage the
option board. Trim any tab fragments that may remain on the option board.
5. Reassemble the option board to the front cover assembly.
6. Insert the display flex circuit into the connector on the option board.
7. Insert the jumper flex circuit into the connector on the option board. Notice the orientation of the
flex circuit. Arrows on the jumper flex point to the correct way of inserting the flex into the
connector.
8. Replace the retainer by placing the two top hooks into the slots below the speaker in the front
cover; then, pivot the retainer into the front cover. Ensure that all four tab arms snap correctly into
the front cover.
9. With the keypad/PassPort option board, display, and retainer correctly in place, the front cover
assembly can now be reassembled per section 3.7.6 Chassis and Front Cover Reassembly on
