Advance settings
Switches inside battery compartment can use for the
following setting:
1. Amplification level increase
If volume is too low even if the control (6) is tuned up considerably,
switch 1 will additionally increase the amplification.
2. Switching off the bass attenuation
To improve speech intelligibility and to prevent hum interference
when receiving sound via the internal coil, a high-pass filter is
integrated to attenuate low frequencies. If low frequencies are
desired, e.g. when listening to music, switch off the filter with
switch 2.
3. Restricting the selection of audio sources
If the audio source is not to be switched over with the button
MIC/LOOP (5), define the operating mode with the switch 3 and 4.
