NOTE: Extensive use of the Backlight reduces es-

timated Battery life. Also, the Backlight does not

operate during a Low Battery Condition or when

the ZEN is connected to a PC.

POWER SUPPLY

The ZEN uses (1) 3 volt CR2430 Lithium Battery. 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 ZEN checks battery voltage every 2 minutes on the surface.

• If voltage of the ZEN 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 the ZEN's voltage decreases to the Alarm level (2.50

volts), the Battery icon will ﬂash and the message CHG >

bAt will scroll (Fig. 4a) for 5 seconds then operation will

automatically revert to Main Time Mode. The ZEN would

then only operate in Watch modes until the Battery becomes

completely depleted.

• Low Battery conditions are not displayed during dives. 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.
