5. The battery caps must be installed so that they are water tight after
replacement. Clean the inside edge of each battery compartment and
seal around the outside of each cover by wiping with a clean damp
cloth to remove any dirt or foreign matter which might prevent a proper
seal. Check cover gaskets for tears or cuts. If damage is found, remove
respirator from service and tag for repair by authorized personnel.

installed, all lights in the HEADS-UP DISPLAY will light for approxi-
mately twenty (20) seconds to verify operation.

touching the face of the battery compartment. Tighten each screw
HAND TIGHT only. DO NOT OVERTIGHTEN. Perform the REGU-
LAR OPERATIONAL INSPECTION to verify proper operation of the
HEADS-UP DISPLAY.
