When setup of this master is finished, click the 'Monitor' button again. The small status indicators
in the upper left of the icons will disappear to indicate that the setup of this monitor group is
complete.
The screen shot on the following manual page shows what the system looks like after the setup
is complete and terminated by clicking again on the Monitor button.
In this example, the handset is not only monitoring channels 1 through 6; it’s a member of Net 1
that also includes channels four and six. This results in the following audio transfers:
The handset user hears the incoming audio of channels one through six. In this example, any
audio received by R2, R4, R5 and R6 is mixed with any incoming audio on the phone lines
connected to PSTN ports P1 and P3; this mixed signal can be heard in the handset and/or speaker.
(Monitor mode functions for channels whether they are free, in a net with the monitoring channel,
or in a net that does not include the monitoring channel).
When the handset user activates the handset PTT and talks, his speech is transmitted only by
radio channels four and six. Monitor Mode does not send audio out from the monitoring channel
to the channels being monitored. Channels 4 and 6 receive this audio only because they are in a
net with the handset.
Channels four and six can hear also each other, but only because they are members of Net 1.
There is no other audio transfer between channels one through six.
Monitor mode
communications are one way only – from the monitored channels to the monitoring channel.
