Maintenance

The device requires very little maintenance except
for daily wiping with a clean, dry or damp cloth.
Use water or lukewarm, diluted solution of water
and household detergent to wet the cloth. Do not
use alcohol or other solvents, and never immerse
the HearCheck Screener in water.
The device has been factory calibrated and should
be returned for recalibration three years after the
manufacturing date labelled inside the ear cover
or three years after first use, whatever is more
appropriate.
If you need to return the device, please contact the
customer service.
To determine proper functionality and adequate
calibration, an operator with normal hearing (or a
person who can hear all 6 signals) should perform a
hearing test on their own at least once a day or
before the device is used for another person
(as appropriate).
