The P20UV can operate in three different modes - Tactical, Law Enforcement, and General. When the light only produces one level of output plus the UV it is set to Tactical Mode. When it produces two levels of output plus the UV it is in Law Enforcement Mode. When it produces three levels of output and UV it is in General Mode. The following steps will reset the light to General Mode.
1. Ensure the P20UV is switched off.
2. Loosen the head of the flashlight.
3. Press and hold the STOBE READY button on the tail cap while simultaneously tightening the head.
4. Once the head has been tightened, the P20UV will indicate the mode that has been selected by flashing once for Tactical Mode, twice for Law Enforcement Mode, and three times for General Mode.
5. To cycle to the next mode, repeat the above process.
