WARNING
To avoid potential explosion, do not short circuit the battery or connector
terminals.
WARNING
To avoid explosion, do not damage the flat joint surfaces. Do not use hammers or
prying tools to open covers. Do not handle covers roughly, or place them on
surfaces that might damage or scratch the flat joint surfaces.
WARNING
To avoid explosion:
1. Exercise care in handling cells/batteries in order to prevent shorting of the
cell with conductive materials such as rings, bracelets, and keys. The cell or
conductor may overheat and cause burns.
2. Do not dispose of the cell/battery in open flame; cells may burst.
3. Do not open or mutilate cell/battery. Opened cells may release corrosive
electrolytes which may have harmful effects on the skin and eyes and may
be toxic if ingested.
CAUTION
To avoid exposing battery terminals, insulating sheet must completely cover the
battery.
WARNING
To avoid explosion, clean both flat joint surfaces of body and cover before
closing. Dirt or foreign material must not accumulate on flat joint surfaces.
Surfaces must seat fully against each other to provide a proper explosion proof
seal.
CAUTION
To avoid shattering the lamp, protect lamp against scratches and abrasions.
