Cleaning the UI 770

Adjusting the volume of the headset speaker

Use the volume control to continuously adjust the volume of
the headset speaker.
"Dynamic Volume Control" ensures that the volume set via the
volume control is kept constant, even if the other party speaks
with varying volumes.

Using the dictaphone output

The dictaphone output can be used to record a conversation in
both directions.
Cleaning the UI 770
Only use a soft – and, if necessary, slightly damp – cloth for
cleaning the UI 770. Do not use any solvents or cleansing agents
