4.4 Periodic Maintenance checks
In theory, no maintenance is needed - in practice it is to the user’s
advantage to inspect a unit at least every year or before and after any long-
term field deployment. Shock, vibration and effects the user has no control
over (vandalism for example) may occur and cause leaks in the case that
result in dust or moisture accumulating inside and damaging components.
For these reasons it is best to perform an annual inspection, clean off the
boards, ensure that all components are in good condition and that socketed
chips are properly seated and that all boards and connectors are firmly
mated. If you encounter a recurrent problem, please advise Refraction
Technology.
