Maintenance

Batteries

Please use the specified model of battery.
Do not mix old and new batteries, or batteries of different brands or types.
Since lithium-ion batteries self-discharge, it is recommended that you remove the batteries if the flashlight will not be used for a long time, and charge the batteries at least once every 2-3 months.

Water Resistance

Ensure O-rings are clean and parts are tightly screwed for rated water resistance.
Do not submerge non-diving lights deeply for long.
The G10 is rated IPX6 waterproof.

Cleaning

Clean lens and body with a soft, dry cloth.
Avoid corrosive chemicals.

Troubleshooting

Problem	Possible Cause & Solution
No Light	Insulation tab not removed. Batteries reversed. Batteries exhausted. Parts not tightened securely.
Dim or Flickering Light	Weak batteries, replace with new ones.
Won't Turn Off	Check switch mechanism/circuit, or reinstall batteries.
Slight Glow from Tail	Characteristic of some electronic switch circuits, not a defect. Loosening the tail cap slightly may stop it.

User Tips

The flashlight does not retain the last used brightness level. It cycles through modes (Low, High) with each turn-on. If turned off at High, it will turn on at Low next time.
Utilize the bidirectional clip for versatile carrying options, such as attaching to a pocket or hat brim.

Safety Warnings

Heat Dissipation: High mode generates heat at the head during prolonged use, which is normal. Use intermittently to preserve LED life.
Eye Safety: Never point the light directly or indirectly at eyes or skin when it is on, as this may cause vision impairment or skin burns.
Children: Keep out of reach of children.
