Inspection
• Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
• Inspect the button, lens, and housing to ensure they are not cracked or damaged.
WARNING: If damage or corrosion is found, return your i450T to an authorized Aqua Lung dealer, and
!
DO NOT attempt to use it until it has received factory prescribed service.
• Remove the cover O-ring by squeezing the sides. Discard, and DO NOT attempt to reuse it.
CAUTION: DO NOT use tools to remove the O-ring. To ensure proper sealing, O-ring replacement is

required each time the battery is replaced.
REMOVE O-RING
Battery Installation
CAUTION: The O-ring must be a genuine Aqua Lung part that can be purchased from an authorized
!
Aqua Lung dealer. Use of any other O-ring will void the warranty.
• Very lightly lubricate the new O-ring with silicone grease and place it on the top rim of the cover.
• Place a new 3 volt type CR2450 lithium battery, negative side down into the battery cavity and ensure that it is
evenly positioned.
• Carefully position the battery cover over the battery compartment. Use the i450T logo as a guide for top/bottom.
• While ensuring that the cover and back of the case are properly aligned, firmly press them evenly and complete-
ly together.
• While holding the battery cover firmly in position against the back of the case, insert the (4) retaining screws and
tighten them until secure by turning them clockwise with a small flat tip 3mm screw driver. DO NOT over-tighten.
