UNIT PROGRAMMING
There are TWO user programmable functions as follows:
DISABLE HANG UP TONE DETECTION and ENABLE DTMF HANG UP
Your DS4 unit has been pre-programmed to detect AUSTRALIAN ‘Hang Up’
tones to determine when the call is complete and to terminate the call connection.
Due to the possibility that your equipment may not generate ‘Hang Up’ tones or
suitable tones, you can ENABLE DS4 to Immediately HANG UP by pressing ANY
DTMF Digit from 0-9.
If your DS4 does not automatically terminate on ‘hang up’ tone detection, you
should ENABLE DTMF Detection.
