BATTERY REPLACEMENT
NOTE: The following procedure must be closely adhered to.
Damage due to improper battery replacement is not covered by
the limited 2 year warranty.
PRELIMINARIES
• Purge the regulator system of all pressure.
• It is not necessary to remove the HP hose from the regulator or the 500AI
from the HP hose. However, if the 500AI is fitted with a Quick Discon-
nect, disconnect it to allow removal of the boot.
• Remove the two screws that secure the Logo Bar, or Compass Assembly,
to the top of the 500AI housing (Fig. 79a) by turning them counter clock-
wise with a 3/32" hex wrench, then lift the logo bar, or compass assembly,
up and off the top of the housing.
BOOT REMOVAL
• Grasp the 500AI with both hands, palms on front sides, fingers on the
rear of the console, and thumbs to the left and right of the top center.
• Carefully push the top of the boot over the tabs on top of the module
while pressing from behind with your fingers.
• Slide the boot down (but not off) the hose, or off the Quick Disconnect.
