500AI

To activate the 500AI -

• press the Select (Right) button once and release.

The 500AI will immediately enter Diagnostic Mode, displaying all “8’s”, fol-

lowed by “dashes”, and then a countdown from 9 to 0 (Fig. 17). The backlight

will illuminate the display throughout the diagnostic check as display func-

tions and battery voltage are checked to ensure that everything is working

properly. A single beep will be emitted to indicate successful completion.

It will also check the ambient barometric pressure, and calibrate its present

depth as zero. At elevations of 2,000 feet (610 meters) or higher, it will

recalibrate itself to measure depth in 'feet of fresh water' instead of 'feet of sea

water'.

WARNING: If the Low Battery icon appears on display follow-

ing diagnostics, AERIS strongly recommends that you DO NOT

dive until the battery is replaced. See the battery replacement

procedure on page 79.

If no dive is made within 2 hours after initial activation, the 500AI will auto-

matically deactivate to conserve its battery power.

Always check the display before entering the water to verify

that it is activated and functioning properly.
