Tone Control
Adjust to suit your own hearing loss. As the tone control (3) is
moved the LED will travel up indicating the higher frequencies and
travel down indicating the lower frequencies. Also adjustable by
remote control.
Gain Control
The factory setting for gain control knob (13) is mid position.
This position is pre-set for most TV Scart and audio output
signals. For some TV sets this may have to be increased to
compensate for a low output signal, especially if using the digital
optical output.
Mute
Mute can be selected by pressing mute button on the remote
control, the green LED (6) will be lit on the amplifier. Or by
manually pressing minus (-) volume button (4) on the amplifier
until red volume indicator is no longer lit and green mute LED is lit
(6).
Loop Indicator
This red LED (7) indicates the signal is being transmitted around
the loop cable. It will flicker with a low volume and increase
flickering with a louder volume.
You can test the system by speaking into the microphone and
seeing if the red LED flickers each time you speak, indicating the
signal (output loop current) is flowing around the cable.
