4 MAINTENANCE
4.1
General cleaning
For cleaning the front panel, use an anti-static foam cleaner and a soft lint-free cloth or tissue. Using abrasive
materials or strong solvents may damage the surface finish or the front panel overlay.
4.2
RF connectors
If the RF connectors or wave guide are used frequently, or left disconnected for long periods, there is a tenden-
cy for dirt and oxide deposits to build up. This increases the contact resistance and creates localized heating of
the “RF out” connector pin, which may cause damage on high power models. Periodically inspect the inner pins
of the RF connectors for damage or deposits, and carefully clean if required.
CAUTION:
Do not use cleaning materials that leave a residue or that are abrasive for cleaning the
RF connectors, as this seriously degrades their performance.
When storing the amplifier for long periods, the RF connectors should be protected with the plastic covers pro-
vided.
4.3 Air-filter cleaning.
CAUTION:
Operating the amplifier with the air-filter clogged, may cause the amplifier
to overheat.
The air-intake-filter on the amplifier front panel should periodically be checked for cleanliness. If it is seen to be
obstructed with any dust or debris this should be cleaned away before the amplifier is operated.
4.4 Repairs
Repair work is to be carried out exclusively by an authorized AMETEK CTS repair department.
WARNING:
Voltages of more than 230 VAC and are generated within the instrument. Do not open
the cover.
Only original replacement parts and accessories are to be used.
Do not continue to use the instrument in the event of mechanical damage occurring. The metal chassis also
performs insulating and protective functions.
4.5 Disposal
For the disposal of electronic devices, the country-specific regulations are to be considered. The
equipment should be delivered to a specialized waste collection center.
Milmega and Teseq’ devices can be returned to AMETEK CTS in England or to their agency for
adequate disposal. Alternatively, the equipment can be handed over to a specialized enterprise
for disposal of electronic devices.
Details to used material and components.
The traveling wave tubes in these products contain Beryllium Oxide, and other components contain PTFE. The
appropriate precautions and regulations must be observed concerning the disposal of this amplifier and certain
internal components.
Do not crush or incinerate.
