Changing the hearing level offsets:
The hearing level offset values are stored in the audiometer’s memory. They can be changed if desired, for
example to use another standard, or if the ISO standard is changed. This is done in a special mode activated
by holding down the keys ‘FREQUENCY DOWN’, ‘MASKING ATTENUATOR DOWN’ and
‘MASKING ATTENUATOR UP’ while powering on the device. When in this mode, the frequency keys
select the frequency to be changed, and the tone attenuator does the actual change. The offset value is
displayed in the Identification display.
