TDH39 earphone, DD45 earphone, CIR55 insert and/or
EARtone 3A insert for Reflex measurements.
Probe earphone incorporated in the probe system for Reflex
measurements.
Connection of the air system to the probe.
Manual control of all functions.
Automatic reflexes:
Automatic, 10 dB above threshold and manually controlled with
stimulus durations of 10 to 30 s.
Automated, first 300 ms from stimulus start.
3 electrodes. 50 cm
Switchable: Software will automatically switch mastoid and
ground if mastoid montage is used. So the user does not need to
replace electrode during testing.
