Memory readout
Memory store
R/P key
After connecting to the line, the R/P functions as a redial key as long as the system has not performed a dialing output
operation. In manual dialing mode, the R/P key functions as the pause data key.
When dialing from memory:
— During a pause operation:
Cancels the pause
— While dialing:
Inserts a pause
During a redial operation:
— During a pause operation:
Cancels the pause
— While dialing:
Ignored
If two or more pause characters occur in the data, the pause cancel operation will cancel all pending pauses in a single
operation.
STORE key
Pressing the STORE key sets the system to memory store mode. Pressing the STORE key again during a memory store
operation cancels all input data.
HOLD ON/OFF key
Controls the on/off state of off-hook mode. No key tone is output at this time.
Keys A1 to A5
These are the one-touch auto-dialing keys. Pressing one of these keys outputs the corresponding memory data from the
DP and DTMF pins.
Keys 00 to 17
These are user-defined keys. When one of these keys is pressed, the LC737212/M outputs the corresponding status and
key code from the serial interface.
