Environmental conditions
be strictly performed only by qualied 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.
• Device calibration is warranted by the manufacturer only if the transducers implemented are directly
connected to the device.
• In the event of replacement of transducers and/or other device components, exclusive use of
Resonance Original spares supplied directly by the manufacturer is highly recommended. Whenever
transducers are replaced, recalibration of the device by qualied technical personnel is necessary.
• The device is provided with a lithium battery type CR2032 which enables constant updating of the
date and time data displayed by the device. Said battery is welded onto the device PCB and possible
replacement thereof must strictly be performed only by qualied technical personnel. Failure to
observe this instruction may result in damages during battery replacement, thus preventing correct
display of the date and time data by the device.
• Blown fuses must be replaced only with the same type of fuses, as specied on the device itself.
