- Kura tal-batterija: Store the battery in a cool, dry place. Recharge the battery every 3 months if not in regular use to prolong its lifespan.
- Punti ta' Kuntatt: Keep all electrical contact points clean. If the flashlight does not turn on or respond, clean the battery contacts and the flashlight's contact points with an alcohol swab.
10 Issolvi l-problemi
- Il-flashlight ma tixgħelx:
- Kun żgur li l-batterija hija mdaħħla sew bit-terminal pożittiv (+) iħares lejn ir-ras.
- Ikkonferma li l-għatu tad-denb huwa ssikkat għalkollox.
- Iċċekkja jekk il-batterija hijiex iċċarġjata.
- Clean battery contacts and flashlight contact points.
- Output decreases or flashlight gets hot quickly:
- This is normal behavior for high-output flashlights, especially in Turbo mode, due to the ATR system. The flashlight reduces output to prevent overheating.
- Ensure adequate airflow around the flashlight during prolonged high-output use.
- Dħul tal-ilma:
- Check if O-rings are properly seated and lubricated.
- Żgura li t-tapp tad-denb ikun issikkat kompletament.
