V3682
6.1 Repair Introduction
The
V3682
is divided into 4 main sections when it comes to part replacability: The flip which contains
the display module and speaker, the mechanical parts, the keypad PCB and the main RF / Logic PCB.
If the RF / Logic board is required to be changed then a full service tranceiver should be ordered as
there is no replacement PCB available. Also a personality transfer would be necessary.
6.2
Mechanical repairs
Assembly replacement level troubleshooting and repair of the
V3682
is limited to isolation and
replacement of the main mechanical parts only (See Exploded parts diagram and associated parts list)
NB. For the immediate future, the front housing and flip assemblies will be ordered as 2 separate
parts but cannot be disassembled once together.
6.3
Basic Modular Troubleshooting
The troubleshooting information in Table 2 shows some typical malfunction symptoms, and for the
corresponding verification and repair procedures refer to the disassembly instructions located in the
disassembly section of this manual. (Section 5).
NOTE
Defective Logic/RF assemblies must be replaced
with pre-tested, pre-phased assemblies
