Installation
Removing the Old Microphone Assembly
1. Use a Model 233-001 Security Screwdriver (Torx T-25 security tip) to loosen and remove the front
panel security screws. Field wiring will restrict complete removal of the front panel. Note all field
wiring terminations to unit and disconnect field wiring to allow front panel to be placed on a working
surface.
2. For the wall-mount telephone, remove the PCBA to allow access to the microphone assembly.
