4000 Series GSM Lite Audio Intercom
Unable to open the gate/door from
the telephone during a call (DTMF
tones not being recognised)
If the DTMF tone to release the gate/door (or other DTMF tones shown in the first user
command table on page 43) does not work then check to see if the
ED#
funtion has been
enabled:
1. Send the following SMS command
1111ED#?
to the GSM and wait for a reply
confirming the status of this function.
2. Note:
If the
1111EDZ
function is set to 01 (enabled) then when answering the call it
will be necessary to first press
0
to accept the call before
3
can be used to operate the
gate/door.
Further notes on how to effectively use these functions and on the setup of these functions
can be found on pages 37 and 38.
If the DTMF tones are not working reliably then try the following adjustments:
1. Send the following SMS command
1111AT1”AT#DTMFCFG=8,2500,1500”?
to the
GSM intercom and wait for a reply.
2. After receiving the reply send the SMS command
1111RBT
then wait for the GSM
intercom to reboot.
3. After the GSM intercom has rebooted test the door opening feature from the
telephone during a call.
If the first option doesn’t resolve the issue then try the following:
1. Send the following SMS command
1111AT1”AT#DTMFCFG=7,2300,1300”?
to the
GSM intercom and wait for a reply.
2. After receiving the reply send the SMS command
1111RBT
then wait for the GSM
intercom to reboot.
3. After the GSM intercom has rebooted test the door opening feature from the
telephone during a call.
