Radio Reassembly — Detailed
3.7.3 Speaker, Microphone, and Universal Connector Flex Reassembly
1. Feed the universal connector tail of the speaker-microphone flex assembly through the opening in
the side wall of the front cover.
2. Peel-off the adhesive liner on the back of the universal connector tail of the flex circuit. Attach the
flex tail to the front cover using the guide pins for correct alignment.
3. Replace the universal connector escutcheon. Make sure that all the connector openings align
with the gold pads on the flex circuit.
4. Align the notch in the speaker at the twelve o'clock position with the tab on the front cover as
shown in Figure 3-8.
5. Place the speaker retainer bracket into the hole on the top of the front cover, and bend the
retainer down to fit underneath the boss below the speaker.
6. If display, keypad, or keypad option board are not involved, reinsert the microphone and boot into
the pocket in the front cover
3.7.4 Keypad and Keypad Option Board Reassembly
1. If you are replacing the PRO7150 or PRO7350 display, use a new double-sided adhesive display
pad (item number 17 on the exploded view diagram in paragraph 3-8). Take care to avoid touching
the display lens.
2. If you are replacing the PRO9150 display, place the tabs at the bottom of the display into the
reliefs in the front cover. Gently snap the beam at the top of the display under the hooks in the
front cover. Take care to avoid touching the front of the display or the display lens.
3. Replace the keypad, and the keypad/option board. Insert display module flex tail into connector
on keypad option board. Push down on latch, closing it securely.
CAUTION: Take care not to damage the display. Do not cut, bend, or pinch the heat seal.
!
Display modules contain CMOS devices. Be sure to use ESD protection.
4. For PRO7150 or PRO7350, insert the "top hooks" of the keypad retainer into the slots below the
speaker (above the display) in the front cover. For all models, snap all four of the retainer arm tabs
in place in the front cover.
NOTE If speaker and microphone not removed, pull the speaker-microphone flex circuit out
of the way during reassembly.
5. Reinsert the microphone and boot into the pocket in the front cover (PRO5150 and PRO7150
cylinder, PRO9150 clam shell).
6. Lay the speaker-microphone flex on top of keypad/option board retainer.
