One 32-digit last number redial memory
One 32-digit SAVE function for storing phone number in off hook status
Note: only 15-digit/31-digit for Tone mode, 1-digit use to identify tone
mode
* Pulse-to-tone (P→T) is provided for PBX operation
* Flash key is available
* Minimum tone duration is 100ms for SC91650, SC91651 or 91ms for
SC91652
* Minimum intertone pause is 106ms for SC91650, SC91651 or 91ms for
SC91652
* Uses 3.579545MHz crystal or ceramic resonator
