When storing the Oxor II for extended periods of time, set its POWER
switch to OFF and remove the batteries. After long term storage follow
Section 4.2 (Adjusting the Instrument) to make sure that the unit is
ready for use.

The Oxor II needs to be calibrated at regular intervals to ascertain that
it still meets its accuracy specification. A regular calibration schedule
should be established. Detailed calibration, maintenance procedures
and parts lists are provided in the Service Manual (19-9133).

As a quick check of the instrument’s operation, perform a response
check by exposing the instrument to a gas source which is depleted of
Oxygen (e.g., cigarette smoke, a breath held for 15 seconds or more,
smoke from a recently snuffed -out match, or bottled nitrogen). If the
instrument doesn’t show a drop in the percentage of oxygen from that
source, or if the reading is obviously in error, DO NOT use the
instrument until it has been serviced by an authorized Bacharach
Service Center.
