OPERATION:
* POWER SWITCH ON THE BACK OF THE MASTER MUST BE ON FOR SYSTEM TO BE OPERABLE.
** DOOR RELEASE BUTTON IS LOCATED BELOW THE "TRANSFER" BUTTON ON THE MASTER.
1. When a station calls in, pick up the handset and press the selector button corresponding to the lit LED.
2. Speak to the person at the remote station through the handset. The person at the remote station
speaks hands free.
3. To release the door at the calling party's location, press the "door release" button while still in
communication with the calling station. This will activate the corresponding relay as long as the button is
being held, which will activate the door release mechanism.
4. If both selective door release and a constant closure are used on a channel, the device connected to
the "constant closure" relay will be on as long as the channel is selected. The "momentary closure"
will only be active when the door release button is pressed.
5. When the conversation is completed, hang up the handset.
