Usage and Maintenance
- Disassembling the sealed head can cause damage to the light and will void the warranty.
- Fenix recommends using an excellent quality battery.
- If the light will not be used for an extended period, remove the battery to avoid damage from electrolyte leakage.
- Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or transportation.
- Long-term use can result in O-ring wear; replace with an approved spare to maintain a proper water seal.
- Periodic cleaning of the battery contacts improves performance — dirty contacts may cause flickering or failure to illuminate; clean with a cotton swab soaked in rubbing alcohol, or contact your authorized distributor if issues persist.
