Safety Instructions
SF15 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.
Do not look directly at the light source or shine to eyes, may cause temporary
blindness or permanent damage to the eyes.
Do not shine a UV light on your skin, may cause damage to or burn your skin.
Operating SF15 for a long time in high powered modes will quickly heat up the
flashlight. This is normal.
Please unscrew the flashlight 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 tailcap by half a turn or remove the battery.
