11. Care and maintenance
Switch off the device and disconnect the power plug before cleaning!
Always disconnect the mains conductor during the cleaning process, and be careful that no fluid enters
inside of the device or the accessories; no alcohol or spirits should be used.
The device requires cleaning the housing with a damp cloth (do not use aggressive cleaning agents); avoid
liquid ingress.
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, it is necessary to disinfect the headset cushion before use on a new patient. This includes
physically cleaning using of a recognized disinfectant. Individual manufacturer’s instruction should be
followed for use of this disinfecting agent to provide an appropriated level of cleanliness.
The insertion headsets tips are disposable: use only once and substitute them before use with a new
patient.
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 R17A 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 with the device. Once device calibration testing using the special purpose apparatus
is complete, it is necessary to run a device function test.
Should transducers require replacement, use only parts provided by Resonance. Upon replacement of
transducers, the entire system will require re-calibration
The device is provided with a lithium-ion battery type 1SP NCR-18650A. Said battery is fitted into the
device and possible replacement thereof must strictly be performed only by qualified technical personnel.
In case of replacement, use only the same battery type.
