Mixed Dialing
Definition mixed dialing: mixed dialing, sequence accepted only when previous sequence been dialed completely. following examples mixed dialing: Example Normal dialing (1st sequence) Example Repertory dialing (1st sequence) Example Redialing Repertory dialing (2nd sequence) Normal dialing (2nd sequence) Normal dialing (2nd sequence) Repertory dialing (3rd sequence) Repertory dialing (3rd sequence)
Repertory dialing (3rd sequence)

There limitation number digits sequences mixed dialing. content mixed dialing combination normal dialing, memory dialing, one-key redialing. HOOK HOOK HOOK entered,
then mixed dialing sequence described above examples will dialed only total number digits does exceed total exceeds digits, then redialing inhibited.
