32 Normal Dialing
The chain dialing buffer may be divided into four sections, allowing up to four numbers to be dialed
out in sequence. For example, if the user enters M01, M03, EM1, and normal dialing (manual dialing),
the content of sections 1 to 4 will be M01, M03, EM1, and normal dialing (manual dialing). When
numbers are entered into the chain dialing buffer, there is no need to wait until the previous dialing
sequence has been completed. Numbers may be entered directly, one after the other, even while
previous numbers are being dialed out.
1. Manual Dialing + Repertory Dialing
Redial buffer content = Manual dialing + Repertory dialing.
2. Repertory Dialing + Manual Dialing
Redial buffer content = Repertory dialing + Manual dialing.
