MAINTENANCE
This instrument requires no regular maintenance beyond routine cleaning and annual
calibration. No special measures need to be applied during preventative maintenance.
We do recommend that the transducers be checked regularly for worn or damaged
transducers or cables. Check that there is no damage to the mains cable and no
mechanical load to the cable or other connectors that might cause damage. Make sure
all connections to external accessories are snug and secured properly. Parts which may
be broken or missing or are visibly worn, distorted or contaminated should be replaced
immediately with clean, genuine replacement parts manufactured by or available from
GSI. The device and accessories are not user repairable. Repairs must be performed by
a qualified service representative only.
It is recommended to turn off the power from the mains when the system is not being
used.
Operational Checks
It is recommended that the user of the instrument should perform a subjective
instrument check of the acoustic stimulus and biologic measurements at least once per
week. The Loopback Test Cable may be used to perform a test of system integrity for
EP/ASSR systems. The Infant Ear Simulator may be used to perform a test of system
integrity for OAE systems.
Calibration and Safety checks
To guarantee that the Audera Pro works properly, the instrument should be checked
and calibrated at least once per year. Have an authorized service technician perform
electrical safety checks on the unit to maintain continued compliance to IEC and UL
60601-1.
The service and calibration must be performed by an authorized service center. If these
checks are not done, EU Medical Device Directive (MDD) and other regulations may be
violated, and warranties may be void.
The use of non-calibrated devices can lead to incorrect test results and is not advisable.
