Use to vary the tone of the signal. Turned in the clockwise direction
the higher frequencies will be emphasised and in the anti-clockwise
direction the lower frequencies will be emphasised. As the tone
control is moved the blue light will travel around the control indicating
the tone position in use.
Loop Level Indicator
This indicates that a signal is being transmitted by the loop cable. It
flickers with a low volume and remains steady with louder volumes.
Testing the system can be done by speaking into a microphone and
seeing the light flash, this will indicate that a signal is flowing round
the cable.
Sound Source Selections
Pressing one of these buttons will select the sound source connected
to the hearing loop driver in the corresponding sockets on the rear of
the hearing loop driver. One or more of these can be selected at any
one time. When the channel is selected a blue light will show in the
button. Press the button again and the light will go out showing that
channel is off.
Microphone
Selecting this will allow sound from connected microphones. If a
microphone is plugged into socket B and the priority button is pushed
in then any sound received by this microphone will override all the
other sounds connected to the loop system. This can be useful when
used to monitor a doorbell or telephone bell or if a partner wants to
talk to the hearing aid wearer through the loop.

Useful to connect to a TV and DVD player so that either may be simply

simultaneously.
