Environmental Conditions - Resonance R25C Manuel D'utilisation

• Device calibration is warranted by the manufacturer only if the transducers implemented are
directly connected to the device. Should transducers be connected to the device through the
inter-positioning or insertion of extension cables and/or interconnection sockets, as may be the
case in the event of connections to soundproof cabins, it is necessary to first proceed with unit
recalibration prior to using 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 qualified 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 qualified 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 specified on the device itself.
