DISASSEMBLY / REASSEMBLY

In the event internal service is required, disassemble the radio in accordance with the following outlined steps. See Figures 6 - 10.

Reassemble the unit by following the steps in reverse order. Observe screw lengths and do not over tighten the screws when reassembling the unit. Torque specifications are listed in Table 3.

Tools Required

TORXâ T6 Driver

M1.5 Hex Driver or Wrench

Needle-Nose Pliers

Small Flat-Blade Screwdriver

Spanner Wrench (top antenna jack)

Spanner Wrench (UDC antenna jack)

Spanner Wrench (volume control and group/channel switch)

Front and Rear Cover Separation

Lay the radio face down and loosen the four (4) Torx screws (A) on the back of the radio; complete screw re- moval is not necessary. See Figure 6. Separate the covers by carefully lifting the Rear Cover Assembly straight-up to avoid bending the connector pins between the RF and Con- trol Boards.

When reassembling the unit, verify the rubber gasket surrounding the perimeter of the cover is in good condition and it is in the groove. Also verify the connector pins align properly. For proper operation, the screws should be tight- ened so there is no gap between the covers. It is recom- mended that the top screws be tightened first while squeezing the radio together to ensure the gap is completely closed. The bottom screws can then be tightened.
