Tools

(Tools) >

Audiometer service

(Audiometer ser-

vice). The data is password protected.

5. When the installation has ended, hold the new transducer within hearing distance and cautiously perform a listening

check.

The purpose of the check is to ascertain that the transducer is functioning correctly (without wrong or excessive sound
levels), not to verify the exact calibration.

Note

•

Note that calibration has been performed only on the transducers supplied. If you wish to use any other trans-

ducer for testing with the device, please contact your local distributor first.
