Both the F201A and F401A function key modules have been manufac- ture discontinued.

Applications

The Function Key Module can be used with the DEFINITY G1, G2, G3, System 75, and System

85.The F201A is used with the 7205H multi-appearance hybrid voice terminal (System 85 and G2 only), while the F401A is used with the 7405D digital terminal.

Physical Description

Feature buttons

The module provides 24 buttons that can only be assigned features. Each button has a square green status light.

Mounting Options

As the illustration shows, the module attaches to the right side of the voice terminal, adjacent to the terminal’s two columns of feature buttons. If a Digital Terminal Data Module is also installed, it must be mounted on the right side of the Function Key Module.

Power

The F201A Function Key Module draws its required power from the system switch through the 7205H voice terminal to which it is attached; no auxiliary power is required. However, when an F401A module is used with a 7405D digital terminal, auxiliary power must be fed through the terminal’s mounting cord from one of the sources listed in the ADJUNCT POWER section of this manual.
