Cautions on recharging

•  Avoid charging in direct sunlight or in a vehicle 

parked under direct sunlight, and make sure to 

charge only when the ambient temperature is 

between 41°F and 104 °F (5 and 40°C).

•  Before charging, be sure that no dust or other foreign 

objects attach to the USB plug. 

•  Do not subject the light to vibrations while charging.

•  Once charging is complete, be sure to disconnect the 

USB plug.

Cautions in use

•  Charging, discharging, and storing in high 

temperatures will cause the rechargeable battery to 

deteriorate faster. Do not place the light inside a 

vehicle or near a heater.

•  If the illumination time is significantly reduced even 

after proper charging, the rechargeable battery may 

be nearing the end of its service life. Dispose of the 

battery as described in “Cautions for dispose”.

Cautions on storage

Cool and dry storage is recommended. For long period 

storage, it is important to charge the battery 30 

minutes every 6 months.
