Safety Instructions
IF23 is a powerful flashlight. Never point it directly at a person, animal or moving vehicles. Doing so could
cause retinal damage. Please do not allow children to play with it. Strobe mode may cause seizure in
persons with photosensitive epilepsy.
Operating IF23 for a long time in high powered modes will quickly heat up the flashlight. This is normal.
Pay close attention to the proper installation of the battery. Always check that the positive end of the battery
faces the flashlight head.
Please unscrew the head half a turn to avoid unwanted activation during transport. It also prevents the
battery from draining while the flashlight is in standby.
Avoid hitting or dropping the flashlight.
Troubleshooting and Maintenance
Disassembling the sealed head can damage the flashlight and voids the warranty.
Sofirn, Ltd. recommends using high-quality brand batteries. Damage by battery leakage voids the warranty.
Remove the battery if the flashlight will not be used for an extended period of time.
To prevent self-discharge or accidental activation during storage or transportation, unscrew the head from
the tube by half a turn or remove the battery.
Every 6 months threads should be wiped with a clean cloth followed by a thin layer of silicone grease.
To maintain a proper level of waterproofness, replace worn-out o-rings with an approved spare.

flashlight. If you experience problems (flicker, shine intermittently or failure turn on) the following root
causes and solutions should be tried:
Reason A: The battery needs a replacement.
