6. Functional description
This section provides a detailed description of each function.
An overview of the visual and audio indications provided by the Streamer
and the hearing instruments are described in section 7 and 8.
6.1 Key lock
To prevent accidental key presses, the Streamer has a key lock function.
The key lock is operated by the slider on top of the Streamer marked with
the padlock symbol.
When the slider reveals the GREEN mark, the keys can be operated.
When the slider covers the green mark, the keys are locked.
The Streamer cannot be operated when the keys are locked, apart from
accepting a call from the mobile phone. (All keys will then be active until the
call is terminated).
If you try to operate the Streamer while the keys are locked, the back light in
the buttons will fl ash a few times to indicate the non-operational mode of
keys in the Streamer.
The key lock is not an ON / OFF function.
