7.2 Routine maintenance
Ventilation grilles
Check that all ventilation grilles are clear of any debris, dust or any other material that may impede the flow
of air. Particularly, check the vents in the bottom panel of the instrument. It is advisable to brush these to
remove any gradual build up of dust.
Failure to clean the ventilation grilles may lead to overheating and eventual failure of the instrument.
Front panel connectors
Routinely inspect the Port 1 and Port 2 N-type connectors for signs of damage or dirt. Use connector-saver
adaptors (male to female through) where frequent connection and disconnection are likely.
