SUUNTO Vyper - Manual (Page 46)

NOTE
The surface interval time is not shown before the first dive.
After activation of the Dive mode or after the dive has ended, the instrument will
automatically switch to show the time keeping display within 5 minutes to conserve
the battery power, unless you press any buttons or start a dive.
5.7.3. Battery power indication
This dive computer has a unique graphic Battery Power Indicator designed to give
you an advance notice of impending need to change the battery. The Battery Power
Indicator can always be seen when the Dive mode is activated. The electroluminescent
backlight will be on during the battery check. The following Table and Figure show the
various warning levels.
Temperature or internal oxidation of the battery affect the battery voltage. If the instru-
ment is stored for a long period, or used in cold temperatures, the low battery warning
may be displayed even though the battery has enough capacity. In these cases, re-
enter DIVE mode to receive the battery power indication.
After the battery check, the low battery warning is indicated by the battery symbol.
