Maintenance and cleaning
• Clean the outer shell of the device using a clean, damp cloth (do not use aggressive detergent
solutions). The penetration of liquids must be strictly avoided.
• During testing operations, headset pads and probe tips come into direct contact with the patient.
Although said components are biocompatible, they are not sterile and they must therefore be
subject to special care:
− After each test session it is necessary to disinfect the headset pads before using them to test
a new patient. To do so, use only commonly marketed non-allergenic disinfectant solutions and
follow the directions supplied by the solution manufacturer.
− The transducers and insertion headsets tips (Insert and Probe) are disposable: use only once
and substitute them before use with a new patient.
− After use of the probe it may occur that earwax (cerumen) has penetrated into the actual
probe duct. Remove the earwax by unscrewing and cleaning both the conical part of the probe
(where the tip is mounted) and the internal ducts, with the cleaning tools provided with the
device. Strictly avoid tampering with the small tubes located internally to the probe, that are
visible only once the conical part is removed.
Refer to the Technical Manual for the complete description of the probe (226 Hz and HF) main-
tenance procedure.
• Calibration and any possible repair, installation and/or update of the device must be strictly carried out
only by specialized technical personnel, duly authorized by the manufacturer and in full compliance
with the terms and conditions specied in the Technical Manual.
• Standard maintenance and device calibration operations are to be regularly performed at one-year
intervals. Standard maintenance operations cover the inspection of the transducer cable conditions,
of the mains power supply cable, of the earphone pads as well as an inspection check to ensure the
device’s outer section and/or cabinet are in good working order. All device calibration operations must
