IMPORTANT
When the Z1’s battery is depleted, all functions are disabled and settings
return to their initial factory defaults. In order to reset settings such as
time and date, you need to charge the Z1 to a point where the charge sta-
tus at the bottom of the screen reads [M] or [H].
NOTE: Leaving your Z1 exposed to direct sunlight or some other very strong
light source can cause the battery power indicator to show a reading that
is temporarily higher than the actual battery level. The correct battery level
should appear after a few minutes of cooling off .

4-6. Low Power Alarm
When battery power reaches a level too low for diving, a low power alarm
sounds that includes a message urging you to recharge the battery. Since
the Z1’s sensors will not function when the power level decreases to the [L]
level, at this point diving is not allowed.
For example, if you started a dive with the power level at [M], and during
the course of the dive it dropped to [L], information relating to the dive will
no longer be displayed. To avoid this dangerous situation, you should never
start a dive with your Z1 unless the battery level is [H] or [M].
