OFF HOOK , D1 , D2 , P , D3 , ..., Dn

1. The pause function can be stored in memory.

2. The pause function may be executed in normal dialing, redialing, or memory dialing (4.0

sec/pause).

3. The pause function can be stored as the first digit in memory.

4. The pause time depends on the number of times the P key is depressed. For example, if the

sequence 1, 2, P, P, 4, 5, 6 is keyed in, then the pause time is 8 seconds.

5. The pause function timing diagram is shown in Figure 3.

(Pulse)

(Tone)

In this case, the device can be reset to pulse mode only by going on-hook, because tone mode

remains enabled after the digits have been dialed out.
