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.
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.
If the above methods do not work please refer to the warranty policy before
contacting your authorized distributor.
