Possible Causes
Faulty trigger switch, Damaged mode selector button, Broken internal wiring to control PCB
How to Fix / Troubleshooting
Safety: Remove the battery before manipulating switches or opening the housing.
- Check for physical sticking: Press the trigger and mode buttons repeatedly. If they stick or do not return smoothly, debris may be lodged around them.
- Clean around buttons: Use a dry brush or compressed air to remove dust from around the trigger and mode switch.
- Test different modes: Try running only in standard mode or only in turbo. If F5 appears only when a specific button is pressed, that switch is likely faulty.
- Service switch assembly: Replacing the trigger or mode switch requires opening the handheld body and soldering or replacing a switch PCB. This should be done by a technician.
