PTRL NV/3 & RXRL NV/3
5.6 Service and Maintenance
Radio link units use natural convection cooling and are not prone to clogging up with
dust. Depending on ambient conditions in the place of installation, the unit may need
cleaning; when this is the case, disconnect the unit from power supply and clean it
outside using a soft brush and a wet cloth.
Equipment must be installed in a rack cabinet or on a stable mount, providing proper
flow of air to the heat sink at the rear of the transmitter.
The equipment is constructed from high quality materials and will need no special
maintenance for some time if the indications provided in paragraph "INSTALLATION
AND OPERATION" are observed.
After a few years continuous duty, have the equipment inspected at the factory or a
specialised centre to ensure it has retained its original specifications. Considering
the high quality and accuracy of the components used, it is very unlikely that the
equipment will need calibrating even after years of service (although it is possible
that the performance of a few components will prove degraded).
Do not alter the internal calibration settings or you will alter the performance
data stated for the transmitter.
It is essential to have the power supply unit carefully inspected in the event the
equipment has been working at high temperatures (higher than 30/35° C).
