BATTERY REMOVAL
The battery compartment should only be opened in a dry and clean environ-
ment, with extreme care taken to prevent the entrance of moisture or dust.
Examine the case back to find the Battery Hatch (Fig. 80a):
• Remove the three screws that secure the battery hatch to the housing by
turning them counter clockwise with a small Philips head screwdriver.
• Lift the hatch up and off of the housing.
• Lift the battery, positive (+) end first, out of the battery compartment.
• Remove the battery hatch o-ring and inspect it for any signs of deteriora-
tion or deformity. DO NOT use tools to remove the o-ring.
• O-ring replacement is highly recommended to ensure proper sealing.
• Closely check the battery hatch and the housing sealing surfaces for any
signs of damage that might impair proper sealing. If found, return your
500AI to your Authorized AERIS Dealer, and DO NOT attempt to use it
until it has received factory service.
• Closely examine the inside of the battery compartment for any signs of
corrosion indicating entrance of moisture into the unit. If found, return
your 500AI to an Authorized AERIS Dealer, and DO NOT use it until it
has received service.
