5. Battery Installation and Replacement

Two 3.6 V Lithium thionyl chloride batteries, AA-size (7400-0011) are included with the Totalizer.
NOTE: THE 8150 WILL NOT OPERATE WITH STANDARD 1.5 V ALKALINE BATTERIES. USE 3.6 V LITHIUM BATTERIES ONLY!
• Observe polarity! Note that both batteries should face the
same direction.
• When the "low battery" indicator appears on the display, both
batteries should be replaced within 90 days.
• Remove and replace battery #1 ¿ rst, then remove and
replace battery #2.
This ensures that all settings and totalizer values are saved.
• If the low battery symbol reappears for more than 10
seconds after installing new batteries, one battery is
reversed, or battery #2 was installed before battery #1.
• Secure the batteries by fastening the hook-and-loop straps.
DISPOSE OF EXPENDED BATTERIES PROPERLY!
Lithium batteries contain hazardous chemicals. Dispose of
batteries according to local regulation.
