L7082 / L7089

6.1 Repair Introduction

The L7082 / L7089 is divided into 3 main sections when it comes to part replacability:  The housings which
contains the alert, speaker, mic, the main PCB which contains RF / Logic circuitry and the keypad
interface and finally the display module which connects to the main PCB via a elastomer connector. 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 L7082 / L7089 is limited to isolation and
replacement of the main mechanical parts only (See Exploded parts diagram and associated parts list

p19 & p20

)

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 4).

NOTE

Defective Logic/RF assemblies must be replaced
with pre-tested, pre-phased assemblies
