Unidirectional:
This program makes maximum use of the power of the microphone arrays in the temples of your hearing aid glasses. Because of the unique beam-forming capacities of the Varibel hearing glasses, this program is the optimal choice for otherwise challenging noisy situations.

Bluetooth streamer:
These settings are used while streaming audio (i.e. music) from your TV or mp3 player through Bluetooth.

Making adjustments
Volume Controls

Within each of the 4 programs you can adjust the volume of your left and right ear independently.
Within the ‘omni’ or ‘Unidirectional’ programs you can additionaly adjust Low-cut and High-cut filters.
To adjust the volume of the left ear, move the handlebar UP or DOWN with the left slider to adjust accordingly.
To adjust the volume of the right ear, move the handlebar UP or DOWN with the right slider to adjust accordingly.
The middle slider controls both left and right ear volume simultaneously, this allows for ‘quick’ volume adjustments for left AND right ear volume, while keeping their balance unaltered.
Frequency control

The handlebars on each side of the graph at the top allow for basic filtering-out low and high frequencies, the so-called Low-Cut filter and High-Cut filter:
Frequencies to the left of the left handle are cut-off. Similarly, frequencies to the right of the right handle are cut off.
Sliding the left handle more to the left allows for even lower frequencies to pass through.
Sliding the right handle more to the right allows for even higher frequencies to pass through.
The resulting middle-section represents the bandwidth of frequencies you are able to hear.
