Disassembly & Reassembly and Replacement Procedures: Transceiver Reassembly Low and Mid Power Models 5-
3. Install a new gasket to the 25 pin connector, Antenna connector and Power connector gas-
kets located on the board.
4. On 800/900 MHz Models only: Insert board slot shield.
5. On Mid Power UHF Models Only: Ensure PA Grounding Clips (P/N 4185738B01) are
attached to shields near Antenna Connector, as shown in Figure 5-16. Replace if either clip is
missing or poorly attached.
6. On 800/900 MHz Models only: Replace the thermal pad attached to the large heatsink (des-
ignator B6501) on the bottom side of the board in the PA section.
7. Check that foam seal is correctly positioned on 25 pin connector on bottom side of board.
8. Insert the main board carefully at an appropriate angle (approximately 30°) into the chassis.
Take care to maintain the position of the Diode Spring.
On Mid Power Models Only (Excluding 800/900 MHz): Start, but do not torque down, screw
number 9 per Figure 5-17 and Figure 5-1.
9. Install the antenna and power connector retaining clips.
10. On Low Power Models Only: Install all screws (except the three screws that retain the PA
shield) with 12 in lbs of torque using a T-10 Torx driver.
On Mid Power 800/900 MHz Models: Install all screws (except the three screws that retain
the PA shield) with 12 in lbs of torque using a T-10 Torx driver.
On Mid Power Models (Excluding 800/900 MHz): Install the screws in the recessed PA
devices, four for VHF and two for UHF, with 8 in lbs of torque using a T-8 Torx driver (see Fig-
ure 5-7 and Figure 5-1). Install the remaining screws (except the three screws that retain the
PA shield) with 6-8 in lbs of torque using a T-10 Torx driver per sequence shown in Figure 5-
17 and Figure 5-1.
11. On Mid Power Models Only: Install the PCB and Audio PA clips.
Note: Once you have reinstalled the PCB and Audio PA clips please check that they fit tightly
on the chassis. If they are loose then they have yielded during the disassembly process and
should be replaced with new clips.
12. Insert the PA shield. Of the three screws that hold the shield to the PCB, torque down the
middle screw first to 6-8 in lbs of torque using a T-10 Torx driver. Torque down the two
remaining screws to 6-8 in lbs with a T-10 Torx driver.
