 If a trigger takes place on the Base Station’s side, the Base Station will
enter callback mode once a call to a group is received successfully (the
callback time will be renewed with every successful call to a group).
 If your choice is callback or follow-on & callback after alarm reporting, the
Base Station will wait 5 minutes for CMS personnel to call back after
reporting (this waiting period is conditioned by the callback timer and its
default is 5 minutes).
 When the CMS calls back within the 5-minute period (this waiting period is
conditioned by the callback timer and its default is 5 minutes), the Base
Station will auto answer the call after 2 beeps and wait for the entry of the
proper Access Code (default is 1111) followed by the (#) key in 15
seconds. Please enter the Access Code at the normal operational speed.
 Upon reception of the correct Access Code, the Base Station will open
full-duplex communication to allow the call recipient to speak to the Base
Station. You can use the following DTMF commands to switch between
speech modes:
- Enter (1) to talk only.
- Enter (2) to open two-way voice communication.
- Enter (3) to listen in only.
- Enter (9) to hang up. You can also put the handset back to the base
cradle to end the call.
- Press (6) or (4) to increase or decrease the speaker volume level in
two-way communication mode. You can also press the volume
switches on the Base Station to adjust the speaker volume level.
- Press any DTMF key except for the designed hang-up key (9) to add
another preset communication period. When a DTMF key is pressed,
its designed shortcut function will be executed and the communication
time extended simultaneously.

key for over 1 second to enable the function.
When your programmed choice is follow-on or follow-on & callback, what
follows will be two-way voice communication, listen-in, or waiting for
commands depending on your setting.
