500AI

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 the number of dives conducted during an opera-

tional period, temperature, and the frequency and duration of backlight use.

Tests and calculations indicate that a new Tadiran® 1/2AA model TL-2150,

.95Ahr, 1.0 ma, Lithium battery will maintain unit operation for approxi-

mately 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 500AI is not

covered by the 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 on the display (Fig.

78a). Upon decreasing to a voltage level that will not maintain proper unit op-

eration, the icon will flash for 5 seconds followed by shutdown of the unit. The

Backlight will not operate during a Low Battery Condition.
