3.7.8 Option Board Installation

1. With the keypad retainer removed and the display ﬂex disconnected as shown in Figure 3-13, the

keypad backer board can be removed without the use of tools.

2. Remove the jumper ﬂex from the connector on the keypad 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.

4. The "breakaway" tab at the top of all option boards contains an extra row of keys and is used only

for PRO9150 models.

5. For other PRO series models, break-off and discard the option board tab, taking care not to

damage the option board. Trim any tab fragments that may remain on the option board.

6. Reassemble the option board to the front cover assembly.

7. Insert the display ﬂex circuit into the connector on the option board.

8. 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.

9. For other PRO series models, 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. For all radio

models, ensure that all four tab arms snap correctly into the front cover.

10. With the speaker microphone/keypad option board, display, and retainer correctly in place, the

front cover assembly can now be reassembled per paragraph 3.7.6.
