again.
• The Backlight will be disabled when there is a Low Battery condition, and be re enabled once the battery is replaced.

POWER SUPPLY
The F10 utilizes (1) 3 volt CR2430 Lithium Battery.
The F10 checks Battery voltage every 2 minutes during operation while on the surface.
• If voltage 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 voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and operation will automatically revert to Main Time screen. The
F10 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. Upon surfacing, the message CHNG >> BATT will scroll (Fig. 3), then
operation will automatically revert to the Main Time screen and only operate in Watch modes until the Battery becomes completely depleted.
