• 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 (IP30, Insert, 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 (226Hz 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 specified 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 be strictly performed only by qualified technical personnel, duly
authorized by the manufacturer and implementing the appropriate apparatus for checking the
levels and frequencies of all the output signals by the transducers supplied on-issue with the
device. Once device calibration testing using the special purpose apparatus is complete, it is
necessary to run a device function test.
• The R25C/R35C device can be used combined with a soundproof or silent cabin as per the
ambient condition requirements suitable for audiometric testing. Prior to connecting the device,
check to ensure that the sockets are compatible with the device features.
