Lion Intelligent Hearing Aid Loop Indicator Sign

I am sure that you have seen 'Loop installed' signs in halls, theatres and other public places. Unfortunately having a sign does not mean that the loop system is turned on and working :(.
Connevans have designed an intelligent illuminated loop sign. This rather clever hearing aid loop sign will light up as green when it detects that there is a loop signal.
The only way that the sign can be activated is from sound going through the room loop. You can adjust the loop signal strength trigger leval and the turn off delay time - 1/2 hour is a good starting point to ensure the loop sign stays on during a break period.
