Test types
Manual Reflex
Manual control of all functions.
Automated Reflex
Automatic reflexes:
- Single intensities
- Reflex growth
Reflex Decay
Automatic, 10 dB above threshold and manually controlled with
stimulus durations of 10 to 30 s.
Reflex latency
Automated, first 300 ms from stimulus start.

Switchable: Software will automatically switch mastoid and ground if
mastoid montage is used. So the user does not need to replace
electrode during testing.
