Fully press the tail switch of the penlight to turn on/off the light.
With the penlight switched on, tap the tail switch to cycle through Low→Med→High→UV.

Intelligent Memory Circuit
The light memorizes the last selected brightness level. When turned on again the previously used brightness level will be recalled.
The light will accumulate a lot of heat when used on High output level for extended periods. When the light has been used on High for 3 minutes, the light will automatically step down by a few lumens until 60 lumens is reached to reduce the temperature. High mode can be reselected.
Usage and Maintenance
- Disassembling the sealed head can cause damage to the light and will void the warranty.
- Fenix recommends using excellent quality batteries.
- Fenix strongly recommends using high-performance Ni-MH rechargeable batteries to get the most out of this light. Alkaline batteries will reduce the runtime relatively.
- If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
- Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare．
- Periodic cleaning of the battery contacts improves the lamp’s performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons:
A: The battery needs replacing.
Solution: Replace battery (Ensure battery is inserted according to the manufacturer’s specifications).
B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don’t work, please contact your authorized distributor.
