BATTERY REPLACEMENT
NOTE: The procedures that follow must be closely adhered to avoid entrance of water into the unit.
Damage due to improper battery replacement (or subsequent leakage of moisture into the unit) is not
covered by the i450T's warranty.
NOTE: The i450T can be sent to Aqua Lung, Regional Distributor, or Authorized Dealer Service for
proper battery change service which includes pressure (depth) and leak testing to the max operating
depth. Standard charges for service will apply.
The battery compartment should be opened only in a dry and clean environment with extreme care taken to pre-
vent the entrance of moisture or dust.
As an additional precautionary measure to prevent formation of moisture in the battery compartment, it is recom-
mended that the battery be changed in an environment equivalent to the local outdoor temperature and humidity
(e.g., do not change the battery in an air conditioned environment then take it outside during a hot sunny day).
Inspect the buttons, lens, and housing to ensure they are not cracked or damaged. If there is any sign of moisture
in the i450T, DO NOT attempt to use it for diving until it receives proper service by the Aqua Lung factory or an
authorized regional distributor.
Data Retention
When the battery is removed, settings and nitrogen/oxygen calculations for repetitive dives will be retained in
volatile memory until a new battery is installed. You will have the choice of saving or deleting the data. The Com-
pass will need to be calibrated after the new battery is installed.
All parts needed for the battery change that follows are provided in the i450T Battery Kit available from your Aqua
Lung Dealer.
Battery Removal
• There is no need to remove the straps.
• Remove the (4) retaining screws located on the back of the case by turning them counterclockwise with a small
flat tip 3 mm screw driver.
• Carefully separate the front and back sections. If necessary, insert a small flat tip screw driver in the slot ma -
chined into the cover at the 11 o'clock position and gently pry the battery cover loose, then lift it off the case.
• Turn the case to one side to drop the battery into your hand. If necessary, gently loosen it with the tip of your fin -
ger. DO NOT use tools to pry it out, or short the positive (+) top of the Battery to the negative ( - ) contact under
