Trouble-Shooting Check List
|PROBLEM: Video is
fine but No Audio from distant classroom.
Squealing noise, or feedback coming from speakers.
power is OFF, but my video monitors are ON.
It is possible for the video monitors to become "out of sync" with the system due to power failures, power glitches, or thunderstorms. To rectify, you must - with the system power button off - manually turn all the monitors off via the power buttons on the video monitors. Now, when you turn your system back ON, your monitors will be back "in sync". with the system.
|PROBLEM: System is
not responding to commands from my control panel.
Although rare, it is possible, particularly after a thunderstorm or power glitch, for the control system to become "latched up". The control system is a computer, and like all computers must be "re-booted" on occasion.
If you are on line with more than one classroom, (via a Multipoint Control Unit), and another classroom can not hear audio from your room, BUT one or more classrooms CAN hear your audio then THE PROBLEM IS NOT IN YOUR ROOM! DO NOT ADJUST YOUR SYSTEM as the problem is elsewhere.
There is only one transmit line from your room going to the network; if anyone can hear you then your transmission is proper.
