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 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 to 
accommodate other radio models.

5.

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.

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.

10. With the keypad option board, display, and retainer correctly in place, the front cover assembly 

can now be reassembled per paragraph 3.7.6.
