Installing the 900 MHz Cordless 
Telephone
The Panasonic 900 MHz Cordless phone is installed 
with your existing key telephone and DBS series 
PBX as shown in the following illustration:
1. SELECTING THE INSTALLATION LOCATION
The base station can be placed on a desk or tabletop 
near a standard 120V AC outlet and telephone line 
jack. The base station can also be mounted on a 
standard AT&T or GTE wall plate, or directly on a 
wall, using the Wall Mount Adapter. 
Avoid locations surrounded by metal surfaces. Keep 
the base station and handset away from excessive 
heat and humidity, and from sources of electrical 
noise (motors, transformers, fluorescent lighting, or 
computers).
Mount the base station and your key telephone at 
least three to four feet apart to avoid noise from the 
key telephone speaker. If you are installing multiple 
base units, place them at least five feet apart.
