Redialing:
After normal dialing, directly keying F key (or On-Off hook once) and keying RD key on keyboard. The
numbers that are stored into LNB memory will be dialed output.
Repertory memory
The EM91420 series incorporated several sets repertory memory and each one can store number up to 16 digits.
These memories were designed to 20 sets types. As in memory storing, if stored numbers are more than 16
digits that only the previous 16 digits can be stored into specific memory. Otherwise, these numbers can be
stored entirely. After memory dialed out, the content of LNB is keeping to current data.
Storing of 20 sets memory
Indirect (three-touch) operation
Off-hook (or turn on HF function), push
(ST, d1, d2, .. , dn, ST, n, n.)
The numbers d1, d2, .. , dn will be stored
into memory location “n n”. The “n n” expressed digital number from 01 to 20.

Indirect (three-touch) memory
To select Pulse or Tone mode.
Off-hook (or Turn on HF function), push
A, n
,
n
key. The numbers that are stored in indirect memory
location “n n” will be dialed out in Pulse or Tone mode as selection . The “n n” expressed digital number
from 01 to 20.
Pause (P) key operation
The Pause (P) key is designed to support pause operation in dialing duration. “P” key can be stored in memory
and it will occupy one digital position.
To select Pulse or Tone mode.
Off-hook (or turn on HF function), push
(d1, d2, .. , dn, RD/P, k1, k2, .. , kn
.
)
These numbers will be dialed
out as following sequence:
d1, d2, .. , dn, Tp, k1, k2, .. , kn.
Pulse to Tone (*/T) key operation
The Pulse to Tone (*/T) key is designed to support toll dialing (long distance call) or PABX system operation.
The “*/T” key can be stored in memory and it will occupy one digital position.
To select Pulse mode.
Off-hook (or turn on HF function), push d1, d2, .. , dn, */T, k1, k2, .. , kn. These numbers will be dialed out
as following sequence:
d1, d2, .. , dn, Tpt, k1, k2, .. , kn.
