Last Number Redial - LNR
Redialing of the last number dialed may be done in TONE or PULSE
modes. Up to 23 digits may be recalled. The memory of the Model 4
will retain the last number dialed for about 15 minutes. To use redial:
After you have dialed a number, go off-line for a moment, then press
“TLK” to reconnect to the network. Confirm that you have a dial tone,
and then press the “R” key on the keypad. The last number previously
dialed will be redialed from memory. Redial is done in the same mode
(Tone or Pulse) as originally dialed.
If you need to dial “9” or some other access number followed by a
pause, simply press the “9” and wait for the next dial tone. Then press
the “R” key to redial the number in memory.
