Parts Replacement and Substitution

When damaged parts are replaced, identical parts should be used. If the identical replacement part is not locally available, check the parts list for the proper Motorola part number and order the part from the nearest Motorola Parts center listed in the “Piece Parts” section in Chapter 1 of this manual.

Rigid Circuit Boards

This family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not accessible, some special considerations are required when soldering and unsoldering components. The printed-through holes may interconnect multiple layers of the printed circuit. Therefore, exercise care to avoid pulling the plated circuit out of the hole.

When soldering near the RF connector, potentiometer, 16-pin and 20-pin connectors:

•Avoid accidentally getting solder in the connector.

•Be careful not to form solder bridges between the connector pins.

•Examine your work closely for shorts due to solder bridges.

5.0Disassembling and Reassembling the Radio — General

Since these radios may be disassembled and reassembled with the use of only 14 (board to casting) screws, it is important to pay particular attention to the snaps and tabs, and how parts align with each other.

The following tools are required for disassembling/assembling the radio:

•Small flat blade screwdriver

•Phillips small 1# screwdriver

•TORX™ T9 screwdriver

•TORX™ T10 screwdriver

•Torque screwdriver set

•Torque spanner

•Hex tool (part no. 6680334F39)

If a unit requires more complete testing or service than is customarily performed at the basic level, send this unit to a Motorola Authorized Service Center. (See Chapter 1 for a list of authorized service centers.)

The following disassembly procedures should be performed only if necessary:
