OPERATING PROCEDURES
6.1
Operating modes
The PCD3332-2/S has 4 operating modes:
1.
On-hook mode or ringer mode
2.
Off-hook mode or conversation mode
3.
Programming mode or store mode
4.
Dial mode.
The PCD3332-3 has 4 operating modes:
1.
On-hook mode or ringer mode
2.
Conversation mode which is divided into hands-free
mode and listening-in mode
3.
Programming mode or store mode
4.
Dial mode.

HOOK MODE OR RINGER MODE
When the chip enable input CE/FDI is LOW the PCD3332
is disabled. In the standby mode, the only current drawn is
for memory retention of the redial digits. During the
standby mode all keyboard pins are HIGH, except ROW 5
which is set to LOW.
6.1.2
D
IAL MODE
Lifting the cradle (handset) or pressing the hook key will
put the set in the conversation mode, an accepted key
entry is processed and may initiate the following:
Dialling the digits entered
Redialling the previously entered digits
Dialling out a repertory memory
Enter programming mode.
6.1.3
R
ESET DELAY TIME
All modes, except for the ringer mode, are terminated by a
line break (CE is deactivated), or by going on-hook. If this
condition is detected, the reset delay time is initiated.
The set will not enter the on-hook state unless the reset
delay has expired. In the event of a line break, the set will
remain in the actual operation mode if the line-break is
ended while the reset delay is still in progress (see Fig.10).
