Operation Instructions

Battery Installation

1. Insert batteries with the positive (+) and negative (-) ends
corresponding to the diagram on the inside of the battery
compartment.
2. Tighten the tailcap by aligning the two gold pins on the inside of the
tailcap with the corresponding holes on the flashlight bottom and
rotating clockwise.
Tips
Inserting batteries in a dark environment: Two of the four battery slots in
the EA81's battery compartment feature grooves indicating that batteries
should be inserted with the negative (-) ends facing forward, while the two
slots with no grooves require the batteries to be inserted with the positive
(+) ends facing forward. In this way, batteries can be inserted correctly
through tactile feedback alone.
Upon loading the batteries, the power indicator light will blink to indicate
the battery power. Please refer to the "Power Tips" section of this manual
for details.
