Introduction 1-3
1.5 General Repair Procedures and Techniques
Any rework or repair on Environmentally Preferred Products must be done using the appropriate
lead-free solder wire and solder paste as stated in the following tables:
Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the identical replacement
component is not locally available, check the parts list for the proper Motorola part number and
order the component from the nearest Motorola Communications parts center listed in the “Piece
Parts” section of this manual.
Rigid Circuit Boards
The 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 through-plated holes may interconnect multiple layers of the printed circuit.
Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.
NOTE
Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit
boards - examples shown below) were developed and assembled using environmentally
preferred components and solder assembly techniques that meet or exceed compliance
to the European Union’s ROHS and WEEE directives (Waste Electrical and Electronic
Equipment (WEEE) Directive 2002/96/EC and Restriction of Hazardous Subtances
(ROHS) Directive 2002/95/EC). To maintain product compliance and reliability, use only
the Motorola specified parts in this manual.
For the identification of lead (Pb) free assemblies, all EPP products will carry the EPP
Marking, shown below, on the printed circuit board (PCB). This marking provides
information to those performing assembly, servicing and recycling operation on this
product, adhering to the JEDEC standard #97. The EPP Marking takes the form of a
label or marking on the PCB.
