Numeric
Keypad The numeric keypad is used to dial telephone numbers and make function selections. The
numeric keypad includes 12 standard dialing keys including the star (
∗
) and the pound (#) keys.
The four special purpose keys are labeled STO, RCL, LNR, and PSE.
STO Key The STO (Store) key is used for storing the last number dialed into repertory memory (18
digits maximum).
RCL Key The RCL (Recall) key recalls a number stored in repertory memory.
LNR Key The LNR (Last Number Redial) key redials the last number called. This feature works in either tone
or pulse modes.
PSE Key The PSE (Pause) key places a four-second pause between numbers that are being entered into
repertory memory. The pause will take place when the stored numbers are redialed, and is used
to access second dial tone when dialing through a PBX.
