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 i750TC's warranty.
NOTE: The i750TC 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 i750TC, 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 i750TC Battery Kit available from your
Aqua Lung Dealer.
Battery Removal
• Locate the battery cover on the end of the housing.
• Apply a coin to the recessed slot of the cover and turn it counterclockwise out of the housing.
• Remove the Battery and discard it according to local regulations governing disposal of Lithium batteries.
