POWER SUPPLY
The Mundial 3 utilizes (1) 3 volt CR2430 Lithium Battery.
Battery voltage is checked 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 the Watch Main Time and Free Surface
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 Watch
Main Time and 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 alternate (Fig. 3), then operation will automatically revert to and remain in Watch Main Time until the Battery becomes
completely depleted.
