1� Check that there is an input signal, green LED In (2�) illuminated during program peaks
2� Adjust the magnetic field strength to 0dB (400mA/m) in the program peaks� Verify the
field strength with Univox® FSM field strength meter� Check the sound quality with the
loop reciever, Univox® Listener� Some installations require adjustment of treble level�
The treble control is located inside the CLS-5T (single control potentiometer inside
the unit)� When increasing the treble there is an increased risk of self-oscillation and
distortion� Please contact Univox support for guidance�

Connecting an alert signal
An alert signal system can be triggered in three ways:
1� External doorbell drive: +24VDC doorbell� Terminal 3-6 on the terminal block
2� External trigger: 5-24V AC/DC� Terminal 4-5 on the terminal block
3� External switch: Terminal 3-4 and 5-7 are shorted separately� The external switch is
connected between 3-4 and 5-7
The acoustic indication supresses the sound in the loop and initiates a broadband harmonic
sound that covers most of the non-linear frequency hearing impairments�
