NOTE: Extensive use of the Backlight reduces
estimated Battery life. Also, the Backlight does
not operate during a Low VT3 Battery Condition
or when the VT3 is connected to a PC.
POWER SUPPLY
The VT3 utilizes one 3 volt CR2450 Lithium Battery. The Battery
should operate normally for 1 year or 300 dive hours if 2 dives
are conducted during each dive period. The VT3 checks its
battery voltage every 2 minutes during surface operation.
• If voltage of the VT3 decreases to the Warning level (2.75
volts), the Battery icon will appear on Surface display
screens (Fig. 2a) as an indication that the Battery should be
changed prior to commencing a series of dives.
• If the VT3's voltage decreases to the Alarm level (2.50
volts), the Battery icon will flash and the VT3 will shut Off.
• 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 remaining to
maintain operation for the remainder of that dive.
