4.3 Call switch

In the CNI4 device, a CALL  switch (magnetic reed switch) is located inside the left side of the instrument
enclosure, behind the material label. This allows the field technician to initiate a call without the need to
open the door of the unit. A hand-held magnetic wand is simply placed against the outside of the
enclosure for a few seconds.
