Tips
Inserting batteries in a dark environment: Two of the four battery slots in
the EA41’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.
After 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.
WARNING
1. Insert batteries using the image on the inside of the battery
compartment as a reference.
2. Do not mix rechargeable and non-rechargeable batteries.
3. Do not mix batteries of different types/brands.
On/Off Operation

batteries for 120 days.
NOTE: With the power indicator off in standby mode, the EA41 can work
for more than 12 months with 4 × AA batteries.

every two seconds when battery power levels reach 50%. The blue LED
will flash quickly when battery power is close to depletion
2. After battery installation or with the mode switch being pressed when
the light is off, the blue LED built into the switch will blink to indicate
remaining battery power. The power indicators will blink three times
when power levels are above 50%; twice when power levels are below
50%; and once when battery power is close to depletion.
Changing Batteries
Batteries should be replaced when any of the following occurs: The
power indicator blinks rapidly, output appears to be dim or the flashlight
