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

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.
