5.1.  How to Avoid Interference Between Lessons When 2 Labs are 
Required 
WILL PLEASE HELP WITH THIS 
If there is more that one lab per school, and you would like to have 6 lesson channels in each console 
then these labs must be placed at least the distance of a hallway in between them or if they are on the 
same side of the hallway, there should be a space of one classroom in between them. By keeping this 
distance, you will minimize the possibility of interference between lesson channels from one room to 
another. 
Another way to avoid interference between lesson channels, if the two rooms must be side by side, 
back to back or above and/or below each other, is to limit the consoles to three lesson sources (three 
channels each) instead of 6. Put three channels in each console, one console having channels 1, 2, and 
3 and the others having channels 4, 5, and 6. Use this method for two Digicall or any other wireless 
systems.
