Battery Charging
The DG100 comes with a rechargeable Lithium Ion battery that, when fully charged,
provides up to 16 hours of continuous use. The battery can be charged over 300 times
to provide over 4,800 hours of dive time. Upon activation, the battery health indicator,
which looks like a battery, is displayed on the top-left corner of the display. When fully
charged the battery icon will appear solid, or full.
NOTE: Always check battery health before diving. It is recommended that the battery be fully charged before every use.
Connect the supplied charging cable to the DG100 by clamping the cable’s tab into the corresponding
slot on the back of the DG100, aligning the cable contacts with the contacts on the back of the DG100.
Plug the USB end of the charging cable into the connector on the supplied power adapter, and plug the
power adapter into an AC outlet. The battery health indicator will begin flashing on and off. The DG100
will charge to 90% in 2 to 3 hours and to 100% in 6 hours. Once the unit has completed charging,
remove the charging cable from the DG100. After charging, short press the “A”Button to update the
battery health display.
WARNING: TO FULLY UNDERSTAND THE USE OF THE DG100, DOWNLOAD AND READ THE MANUAL (WWW.RJEINT.COM)
WARNING: The DG100 default setting is to measure depth in feet (Imperial). To display depth in meters (Metric), please follow
instructions under “Operations Menu Function”. Ensure that you are aware of the DG100 depth setting, feet or
meters, before diving.
WARNING: Diving is a dangerous and potentially life threatening activity. The DG100 digital depth gauge must be used by a
