Preliminary W91510DN SERIES
a. The R/P key can execute the redial function only as the first key-in after off-hook; otherwise, it
will invoke pause function.
b. The redial memory content will be D3, …, Dn.
c. Redial memory can be checked in memory check mode.

, R/P )
d. If redialing length oversteps 32 digits, the redialing function will be inhibited.
2. OFF HOOK (or ON HOOK & _HFI ¡õ ), D1 , D2 , ..., Dn , Busy, OKR
a. If the dialing of D1 to Dn is finished, pressing the OKR key will cause the pulse output
pin to go low for 2.2 seconds break time and 0.6 seconds pause time will automatically be
added.
b. If the pulses of the dialed digits D1 to Dn have not finished, OKR will be ignored.
c. The one-key redialing function timing diagram is shown in Figure 3.
