Installing the 900 MHz Cordless Telephone
The Abrivo 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.
2. CONNECTING THE TELEPHONE CORDS
The base station for your 900 MHz phone must be connected to the Panasonic
PBX. You can also connect a Panasonic key phone to the base station.
Caution:
Never install telephone wiring during a lightning storm.
Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
