Safety Instructions
HS41 is a powerful flashlight. Never point it directly at a person, animal, or moving vehicles, as it could
cause retinal damage. Please keep it out of the reach of children. Strobe mode may trigger seizures in
individuals with photosensitive epilepsy.
When operating HS41 for an extended period of time in high-powered modes, the flashlight will heat up
quickly. This is normal.
Ensure proper installation of the battery by checking that the positive end faces the flashlight head.
Prior to transport, remove the battery from the flashlight to prevent unintended activation and battery
drainage.
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, please 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.
Troubleshooting: Clean battery contacts regularly as dirty contacts may impair the performance of the
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.
Solution: Replace the battery with an approved type of a fully charged battery.
Reason B: Threads, PCB board contact or other contacts are dirty.
Solutions: Please clean the contact points with a cotton swab soaked in rubbing alcohol.
Reason C: The flashlight will not turn on upon first use.
Solution: Please do not forget to remove the insulation sticker from the battery on first use.
If the above methods do not work please refer to the warranty policy before contacting your authorized
distributor.
