Do not disassemble the product and ensure against it's contact with water
Contact with internal components of the product may cause an electric shock. In case of any malfuction entrust the servicing
of the product exclusively to a certified service centre. Contact with water can create a short circuit in the product and
consequent damange to property or personal injury.
Use appropriate cable types
To ensure compliance with the parameters of the product, only use cable types recommended in this guide.
Dispose of used products and trasmitter sensors with respect to the environment
Transmitter sensors contain hazardous substances. Dispose of them in accordance with the current legislation on
environmental protection.
Use the transmitter only with the appropriate certified DEGA products
The device is certified as functionally and technically qualified only with original "DEGA" accessories. In case of using the
device with any other products the manufacturer is not liable for any damages that may occur.
Undertake regular functional checks and calibrations of the transmitter
Perform regular "CALIBRATION" (setting the detection limits, checking the responsivness of the sensor, checking the
functionality of the transmitter) and "OPERATIONAL AND FUNCTIONAL CHECKS" of the entire detenction system (sensor
excitation with subsequent control of optical and audible alarms, triggering fans, shutdown technology, etc.). Perform
calibration and operational and functional checks only at certified service centers with a valid certificate of competence or the
manufacturer.
Warning: The transmitter automatically checks it's calibration period - the period of validity of it's calibration. After 12 months since the
last calibration (Max. calibration period) the transmitter will transmit this fact to the host system. The transmitter must be calibrated
immediately at a certified service center with a valid certificate of competance or the manufacturer. See section "Monitoring the
calibration peridos".
