■ PABX auto-pause is 2.2 seconds
■ DTMF Timing:
Manual dialing: minimum duration for bursts and pauses
Redialing: calibrated timing
■ Hands-Free control function
■ Wide operating voltage range: 2V to 5.5V
■ Key-in beep tone output
■ Digits dialed manually after redialing are cascadable and stored as additional digits for the next redialing
■ Uses inexpensive ceramic resonator (3.58 MHz)
■ Two versions for different telephone systems
■ Built-in power up reset circuit
