ALARM

NOTE: Extensive use of the Backlight reduces estimated Battery life. Also, the Backlight does not operate during a Low Battery Condition or when the GEO is connected to a PC.

POWER SUPPLY

The GEO utilizes one 3 volt CR2430 Lithium Battery. When used as a Dive Computer, the battery should operate normally for 1 year or 300 dive hours if 2 dives are conducted during each dive period. The GEO checks its battery voltage every 2 minutes during surface operation.

If voltage decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface display screens (fig. 3a) as an indication that the Battery should be changed prior to commencing a series of dives.

If voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the message CHNG > BATT will scroll at the top of the display (Fig. 4). Operation will automatically revert to Main Time Mode. The GEO would then only operate in Watch modes until the Battery becomes completely depleted.

Low Battery Warning/Alarm conditions are not displayed during Dive Modes.

If a Low Battery Condition was not displayed prior to starting a Dive, and a Low Battery Condition occurs

during the dive, there will be sufficient Battery power to maintain operation for the remainder of that dive.
