7.2. Further programming options
In addition to programming auto-dial numbers, several other features
can be programmed using a tone-phone.
7.2.1
Time-out
The call time out is factory set to 7 minutes, meaning that the phone will
drop the call and go back on hook electronically after this period even if
a call is in progress. This feature is provided to guard against the
handset being left off hook and tying up the line.
The timer can be set in increments of 10s from 60s to 9980s by entering
the code *50, followed by the required timeout divided by 10s, followed
by #.
For example to set the timer to 3 minutes enter *50 18 # (3min is 180s,
18 is 180/10).
This command must be entered between entering the PIN and closing
the phone down with *99 (ie during step 5 of the quick programming
guide above).
To disable the timer use a value of 999, ie *50 999 #.
The phone will respond to a successful command with a single tone.
7.2.2
Inserting a pause into an auto-dial number
To enter a pause (approx 1 second gap) into a dial number, use the
digits *1.
For example to program 9 <pause> 12345 into memory 1, use
*101 9 *1 12345 #
This command must be entered between entering the PIN and closing
the phone down with *99 (ie during step 5 of the quick programming
guide above)
7.2.3
Auto-answer behaviour
To set a SMART help point to automatically answer in a voice call, use
*70 0 #
To set a SMART phone to answer immediately, and only ring after auto-
answering (ie for silent monitoring), use
*70 240 #
The actual formula for rings before and after auto-answer is
*70 n #
Where n is a number between 0 and 255 calculated as follows:
