Monitoring

The RTR-57C can be set to patrol and monitor RTR-51/52/53 or 
RVR-52 groups and display in order the current readings for view.

NOTE:

●

The amount of communication time depends on the number of registered 

groups and remote units. Please note that if the monitoring interval is set 
for less time than communication takes to complete a round of monitoring, 
the system will automatically extend the interval to allow for the necessary 
amount of communication time.

units with which communication is possible will be displayed consecutively 
every 2 seconds. This can be done for up to 120 units; the 121
