b. If the dialing of D1 to Dn is finished, pressing the R key will cause the pulse output
pin
to go low for 2.2 seconds break time and 0.6 seconds pause time will automatically be added.
c. If the pulses of the dialed digits D1 to Dn have not finished, R will be ignored.
d. The redial function by R key has no break time (2.2 sec.) if it is the first key-in after off-hook.
e. The R key uses the same redial buffer as the redial function by R/P1 or R/P2 key,
the
and it is active during normal dialing or repertory dialing.

1. The pause function is executed in normal dialing, redial dialing, or memory dialing.
2. The pause duration of 2.0 or 3.6 seconds per pause is selected by keypad, but only one pause time
can be stored in memory.
3. A detailed timing diagram for the pause function is shown in Figure 5.

3. The dialer remains in tone mode when the digits have been dialed out and can be reset to pulse
mode only by going on-hook.
4. The pulse-to-tone function timing diagram is shown in Figure 6.
