Changing Batteries:
Grip knurled back cover and rotate counter-
clockwise until the ‘unlock’ icon is in alignment
with the arrow – this is on the housing at the
base of the pressure connection.
Remove cover by pulling straight back
and replace AA alkaline batteries accordingly;
ensure that the batteries are in the proper
polarity position.
For reattachment of cover, align the ‘unlock’
icon with the arrow, push cover straight in
then turn clockwise until the arrow is in
alignment with the ‘Lock’ icon.
Note: Reinstallation of the back cover may
cause the unit to read negative pressure.
This is a temporary issue as the internal case
pressure will be relieved by the case vent and
equalize with atmospheric pressure (90% of
the offset will equalize within 1 minute, the
remaining 10% may take up to 5 minutes).
