HOOK , R/P
The R/P key can execute the redial function only as the first key-in after off-hook;
otherwise, it executes the pause function (3.6 s).
Keys stored in redial memory: 0 to 9, #, R/P, A, M1, M2, M3, N, * (only tone mode)
Characters F1, F2, F3, Earth, (* in pulse mode) can only be stored in Mn, Ln and N
memory.
Characters F1, F2, F3, Earth, (* in pulse mode) will not be dialled out from redial
memory; dialling out was stopped, when recognizing one of the above characters.
Example:
OFF/ HOOK, D1, D2, F1, D4, D5, S, S, M1
a) ON/OFF-HOOK, R/P
b) ON/OFF-HOOK, M1
Content of redial memory can be copied to Mn, Ln, N; but copying memory Mn, Ln, N to
itself or to another memory (except redial memory) will erase the destinated memory.
