1.3.12 Connection of Monitor Input
In some cases it may be desirable to prevent the paging transmitters from transmitting,
e.g. when a carrier wave is already in the air.
Monitor input can be used to prevent the Central Unit both from activating the output
stage in the transmitters and from sending the transmitter code to them when a carrier
wave is in the air.
