Notice: If the dedicated Audiometer keyboard is used, its functions will be dependent on the
programming that the selected user has entered as his default.
Notice: To establish conformity with the IEC 60645-2 standard, it is important that the speech input
level is adjusted to 0VU. It is equally important that any free field installation is calibrated at the site
where it is used and under the conditions that exists during normal operation.
Warning: Only recorded speech material with a stated relationship with the calibration signal should
be used. In the calibration of the instrument it is assumed that the calibration signal level is equal to
the average level for the speech material. If this is not the case, the calibration of the sound pressure
levels will be invalid and the instrument needs recalibration.
