Mode of Operation
Minicall12 verifies coded radio frequency signals sent by corresponding transmitters and operates display and signalisation on receipt
of a correct signal. The Minicall-12 is not a medical device.
It must be noted that for applications or installations involving wireless transmission and which could have an influence to safety of man
or machine there may be a risk of unforeseen operation from extraneous uncontrolled radio signals.

Description
Minicall 12 is a self observing calling system with up to 12 calling lines. For each calling line (channel) a maximum of 5 transmitters
may be programmed. So, up to 60 transmitters (MT-12 and WT-12) may be used within this system.
Once a call is initiated at transmitters side, the Minicall12 will signalize optically and acoustically the corresponding channel and will
transmit this call also to portable receivers (R-12). The display of portable receivers will show the channel Number (1..12). A maximum
of 5 portable receivers may be programmed.
For the additional display of calls an optional signaler (SG-12) can be used on each channel. In addition to the function as a room
signal light, digital outputs can also be used to control external signals.
An active call may be cancelled by pressing the corresponding push button at the Minicall12 or by confirming the call with a portable
receiver. If more than 1 call is active, the portable receivers will show them one after the other and only the call appearing in the display
may be confirmed by pressing the push button “OK” twice.
If there is to realize a bigger range of operation, up to 5 repeaters may be used.
For any incoming call there is a potential free contact inside the housing which will switch for 1 second (up to 15 seconds selectable).
This is for external signalisation devices if needed.
An interruption of radio communication to a transmitter is shown by flashing periodically twice the channel LED and a short BEEP. Just
press the push button to stop signalisation if the problem is known.
Low battery of any transmitter is signalized by flashing 5 times periodically the corresponding cannel LED.
Summary of signalisation in normal operation mode:
„LED ON” is permanently on
AC-adaptor (Supply) is connected
„LED ON” flashes once a second
Minicall12 is running on battery supply (AC-adaptor missing)
„LED DATA” flashes shortly
signalizes radio communication
„LED DATA” flashes shortly twice
Batteries of Minicall12 are empty or taken off
„Channel LED” (1…12) is permanently on
call (1…12) has been received
„Channel LED” (1…12) flashes periodically twice
radio communication to the corresponding transmitter fails
“Channel LED” (1…12) flashes 5 times periodically
battery capacity of the corresponding transmitter is low

Installation and functional check
4.1
Minicall12
Just connect the AC-adaptor and you will hear a starting melody and the green “LED ON” will turn on. The yellow “LED DATA” flashes
about twice a second. This will show, that the battery supply is still not activated. Keep this state until later.
