If the phone number exists it will be displayed upon the bottom line. Use the ‘CANCEL’ button to delete each digit
in the phone number. Once all the digits have been deleted press the ‘END’ key to save the empty phone number.
Selecting DTMF or pulse (Decadic) dialling
Factory Default: DTMF
This will set how all phone numbers are dialled to the phone exchange. Most new exchanges use DTMF since it
is
quicker. Decadic dialling should be used as a last resort.
Select “Dialling Method” from the “Dialling Menu”.
Use the ‘LEFT’ and ‘RIGHT’ arrow keys to select “DTMF” or “Pulse”. Press ‘END’ to confirm selection.
Enabling dial tone checking
Factory Default: Enabled, 3 seconds.
Dial tone checking looks for the absence of a valid free phone line before making a phone call. For example,
someone may be using a normal telephone in parallel on the same line, therefore the interconnect is unable to use
it.
Note: In some telephone exchanges, particularly older ones, the dial tone on the telephone line before
dialling is different to the newer standards now used. In these cases dial tone checking has to be disabled.
Select “Dial Tone Wait” option from the “Dialling Menu”.
Use the ‘UP’ and ‘DOWN’ arrow keys to select the time in seconds to wait for a dial tone. To disable dial tone
checking select “00 Second(s)”. The maximum time to wait for a dial tone is ten seconds. Press ‘END’ to save.
