Battery Installation
Before first use, please unscrew the tail cap and remove the insulating paper. If the battery needs to be replaced,
make sure that the positive end of the new battery faces the flashlight head when you put it in.

The indicator shows the power status for 5 seconds after turning IF23 on.
Green = remaining battery power is good (70% - 100%).
Red = remaining battery power is poor (30% - 69%).
Flashing Red = critical power (less than 30%), please replace or recharge battery as soon as possible.
Charging
IF23 offers a USB type-C charging port for convenient charging. Please connect it with the included USB-A to
