Maintenance
The 805QS contains no user serviceable parts and cannot be repaired on site. It must
be returned to the factory. Disassembly of the instrument by unauthorized persons will
invalidate the warranty. If there is a risk of debris accumulating in the pressure port, it
should be cleaned. Care and caution must be taken when cleaning the pressure port to
prevent damage to the diaphragm.
