AND VOLUME CONTROL FUNCTION

Preliminary

Auto Insert Pause Time Function

EM91865 Provides a new function - Auto Insert Pause Time function - for PABX system user. In PABX

system, we usually use a special number to identify the phone want dial out or just a internal phone. So between

the first and second number, the PABX system will switch to central office, that will be few second switch time.

The auto insert pause time function will auto insert the pause time between first and second digit in redialing mode.

This function are provide a pause time to wait PABX switch to Central Office. In fact, the pause time are record

the waiting time of last dialing between the first and second digit. The auto insert pause minimum duration are equal

0 second, maximun duration are equal 3.5 second, and pause duration scale are 0.1 second. So, if the time during

user keying first and second digit are longer than 3.5 seconds, the auto insert pause time will be limited at 3.5 second.

By this function, we can redial the correct number out in PABX system. This function can select enable or disable

by R_option.

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, P , k1, k2, ..... ,kn). These numbers will be dialed out

as following sequence :

d1, d2,.....dn, Tp, k1, k2, ..... ,kn (Tp are the pause Time)

SAVE redial memory

The SAVE memory is designed in EM91865 to support digits capacity buffer for second redial, pager, special

memory for memo and other system applications.

Storing : EM91865 support two operating methods to store numbers into SAVE redial memory.

Method 1 :

• To select Pulse or Tone mode.

• Off-hook(or turn on HF function), push d1, d2 ....., dn. The numbers d1, d2,..., dn will be dialed out in Pulse

or Tone mode as selection.

• After dn had been dialed out and push [ST]. SAVE key. If the keying numbers are more than 32 digits that

content of SAVE memory can not be updated. Otherwise, these numbers will be stored into SAVE memory.

Noted : In the [ ] key allows to be omitted.

• SAVE buffer are the length 32 digits number.

Method 2 :

On or Off-hook (or turn on HF function), push ST, d1, d2 ....., dn, [ST], SAVE. If the keying are not over 32 digits,

the numbers d1, d2, ....., dn will be stored in SAVE redial memory automatically.
