Operating Instructions
1. Power On/Off (Tail Switch)
The tail switch controls the basic on/off function:
- Momentary On: Tap the tail switch.

2. Mode Selection (Side Switch)
Once the flashlight is on, use the side switch to cycle through the various brightness levels and special modes (Strobe, SOS) available in the currently selected SET mode.
3. SET Mode (ACE Technology)
The Fenix PD26R ACE features three distinct SET modes, allowing you to customize the available light levels based on your needs. To change the SET mode, press the 'SET' button located near the head of the flashlight. The indicator lights (1, 3, 5) will show the currently active SET mode.

Maintenance
- Cleaning: Clean the flashlight body and threads regularly with a soft cloth.
- Lubrication: Apply a thin layer of silicone grease to the O-rings periodically to maintain water resistance.
- Battery Care: Remove the battery if the flashlight will not be used for an extended period. Store batteries in a cool, dry place.
- Water Resistance: The flashlight is IP68 rated, meaning it is dustproof and submersible up to 2 meters for 30 minutes. Ensure O-rings are intact and properly seated before exposure to water.
Troubleshooting
If your Fenix PD26R ACE flashlight is not functioning correctly, please refer to the following common issues and solutions:
- Flashlight does not turn on:
- Check if the battery is inserted correctly with the positive (+) end towards the head.
- Ensure the battery is charged.
- Tighten the tail cap securely.
- Intermittent operation or flickering:
- Clean the battery contacts and the flashlight's contact points with an alcohol swab.
- Ensure the battery is fully charged.
- Check for loose connections in the tail cap or head.
- Brightness decreases or mode changes unexpectedly:
- This may be due to the intelligent overheat protection. The flashlight will automatically downshift to a lower brightness level to prevent overheating. Allow the flashlight to cool down.
- Check the battery level; low battery can affect maximum output.
If the issue persists after trying these steps, please contact Fenix customer support for further assistance.
