UPLOADING/DOWNLOADING
As previously described (page 40), the DSX can be paired using the Bluetooth® feature. This requires a mobile
device running Di software and equipped with Bluetooth® functionality. Follow the Di instructions
on how to pair your devices and use the upload/download features.
CARE AND CLEANING
Protect your DSX from shock, excessive temperatures, exposure to chemicals, and tampering. Protect the lens
against scratches with lens protector. Small scratches will naturally disappear underwater.
• Soak and rinse the DSX in fresh water at the end of each day of diving, and check to ensure that the areas
around the low pressure (depth) sensor, electrical 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 DSX under gently running fresh water. Towel dry before storing.
• Keep your DSX cool, dry, and protected during transport.

SERVICE
!
WARNING: At a minimum, annually check the elevation reading on the Alt 1 screen (p. 25) and Dive
Planner, Time Limits (p. 30) for accuracy. If your DSX is ever out of calibration (incorrect elevation read-
ing, incorrect No Decompression Dive Times in the planner, or showing a depth reading at the surface) or
displays an error code message, it must be serviced at the factory before use.
If required to return your DSX to Apeks:
• Obtain an RA (Return Authorization) number by contacting your regional Apeks customer service. www.apeks-
diving.com
• Record all dive data in the Log and/or download the data stored in memory. All data will be erased during factory
service.
ALTITUDE SENSING AND ADJUSTMENT
Prior to the first dive of a series of repetitive dives, Altitude (i.e., ambient pressure) is measured upon activation
and every 15 minutes until a dive is made.
• While it is operating in Surface Mode after a dive, measurements are taken every 15 minutes during the 24 hour
period after surfacing.
• Measurements are only taken when the unit is dry.
• Two readings are taken, the second reading 5 seconds after the first. The readings must be within 1 foot (30 cm)
of each other to record that ambient pressure as the current altitude.
• No adjustments are made during any time that the water contacts are bridged.
When diving in high altitude waters from 916 to 4,270 meters (3,001 to 14,000 feet), the DSX automatically
adjusts to these conditions providing corrected depth, and reduced No Decompression and O2 Times at intervals
of 305 meters (1,000 feet).
At an elevation of 916 meters (3,001 feet), Depth calibration automatically changes from feet of seawater to feet
of fresh water. This is the first adjustment to the algorithm. When the Conservative Factor feature is set to ON, No
Decompression Times are calculated based upon the next higher 915 meter (3,000 foot) Altitude. All adjustments
for altitudes greater than 3,355 meters (11,000 feet) are then made to allowable dive times for 4,270 meters
(14,000 feet). At Sea Level, calculations are based upon an altitude of 1,828.8 meters (6,000 feet).
The DSX will not function as a dive computer above 4,270 meters (14,000 feet).
