UPLOADING/DOWNLOADING DATA

As previously described (p. 32), the Geo 4.0 can be paired using the Bluetooth® feature. This requires a mobile device with Bluetooth® running 

D software.

The Settings Upload portion of the program can be used to set/change the Gases, Set AL group (Alarms), Set UTIL group (Utilities), and Set TIME 

group (Time/Date) using the same Interface System. The Mode settings must be entered using the Geo 4.0 button controls.

Information available for retrieval* (download) from the Geo 4.0 includes items such as dive number, surface interval time, depth, dive time, start 

dates/time, lowest temperature, sampling rate, set points, TLBG Bar Graph, and ASC Bar Graph.

*FREE Dive information is only available using the Di application.

Refer to the D software application for further instruction on linking your Geo 4.0 to your mobile device.

CARE AND CLEANING

Protect your Geo 4.0 from shock, excessive temperatures, exposure to chemicals, and tampering. Protect the lens against scratches with an Instru-

ment Lens Protector. Small scratches will naturally disappear underwater.

•  Soak and rinse the Geo 4.0 in fresh water at the end of each day of diving, and check to ensure that the areas around the Low Pressure (Depth) 

Sensor, wet contacts, and buttons are free of debris or obstructions.

•  To dissolve salt crystals, use lukewarm water or a slightly acidic bath (50% white vinegar/50% fresh water). After removal from the bath, place 

the Geo 4.0 under gently running fresh water. Towel dry before storing.

• Keep your Geo 4.0 cool, dry, and protected during transport.

INSPECTIONS AND SERVICE

Your Geo 4.0 should be inspected annually by an Authorized Oceanic Dealer who will perform a factory prescribed function check and inspection 

for damage or wear. To keep the 2 year limited warranty in effect, this inspection must be completed one year after purchase (+/- 30 days). Oce-

anic recommends that you continue to have an inspection performed every year to ensure it is working properly. The costs of annual inspections, or 

inspections relating to water tight integrity, are not covered under the terms of the 2 year limited warranty.

BATTERY REPLACEMENT

CAUTION: 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 Geo 4.0's warranty.

The battery compartment should be opened only in a dry and clean environment with extreme care taken to prevent the entrance of moisture or 

dust. 

As an additional precautionary measure to prevent formation of moisture in the battery compartment, it is recommended 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 environ-

ment 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 Geo 4.0, DO NOT attempt 

to use it for diving until it receives proper service by the Oceanic 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.

All parts needed for the battery change are provided in the Geo 4.0 Battery Kit available from your Oceanic Dealer.
