AINTENANCE AND WARRANTY
11.1 Maintenance
,
Strictly follow the instructions outlined in this section.
11.1.a Clogging caused by dust
Since the transmitter is cooled by air, it is subject to clogging caused by dust. Because of the high-quality materials used in its
manufacture, if it is installed as set forth according to the instructions in Chapter 6, it will not require special maintenance for quite
some time.
A regular service routine, mainly to remove internal dust, is recommended every 6 months to one year at the most. Keep in mind
that 90% of the air circulation is restricted to the main internal ventilation channel and does not affect the components.
11.1.b Ventilation fan
If the transmitter is equipped with forced air, we recommend changing the ventilation system regularly, especially in higher-
temperature environments. As a precaution, substitution is recommended every 2 years; always use the same, high-quality, ball
bearing type fan.
11.1.c Periodic overhaul
After a few years of continuous service, it is advisable to have the device overhauled in our factory or in a specialized Siel
laboratory, where its characteristics can be checked against the initial parameters. If necessary, regular maintenance operations can
also be carried out at this time.
It is especially important that the power supply be overhauled if the transmitter has been working at high temperatures, over 30 -
35°C.
Never modify the original settings without utilizing the proper testing equipment and standard procedures, and without having
received authorization by Siel or an authorized representative.
11.2 Warranty
Like all Siel solid-state equipment, this transmitter series carries a one-year warranty on all its components, with the exception of the
final RF power module, which may be damaged by faulty output connectors.
