BATTERY LIFE
Battery consumption rate varies throughout periods of operation, which begin
upon activation and continue for 24 hours after surfacing from a dive. The ex-
act number of dives, or hours of operation, that you will obtain with a battery
is subject to variables, such as, temperature, the number of dives conducted
during an operational period, and how often the backlight is used.
Tests and calculations indicate that a new Tadiran® 1/2AA model TL-2150,
.95Ah, 1.0 ma, Lithium battery will maintain unit operation for approximately
300 dive hours (if 1 - 1 hour dive per dive day) to over 600 dive hours (if 2 or
more 1 hour dives per dive day). Yearly replacement is recommended.
NOTE: The disposable battery supplied with the unit is not
covered by the Pro Plus limited 2 year warranty.
LOW BATTERY CONDITION
During unit operation, voltage level is checked every 10 minutes. A Low Bat-
tery condition is indicated by the Battery icon appearing in the lower display
(Fig. 77a). Upon decreasing to a voltage level that will not maintain proper
unit operation, the icon will flash for 5 seconds followed by shutdown of the
unit. The backlight will not operate during a Low Battery Condition.
