Safety Information
Read the manual carefully before using your SHIELD.
SHIELD is designed for paved road. Recommend not to use
it in trail to prevent damaging the tail light.
Always pay attention to the remaining battery power
while using.
Charge devices when the ambient temperature is between
41°F and 104°F (5°C and 40°C).
Cool and dry storage is recommended. Charge the battery
at least 60 minutes every 3 months. Check regularly that
the tail light is attached securely.
Dispose the device according to local regulations
SHIELD is designed to be a supplement, and NOT a
replacement to hand signals. Please comply to local traffic
regulation, when you ride on road. Having lights is good
practice, but is no guarantee against preventing an
accident or collision.
SHIELD’s Anti-theft Alarms provides better security to your
bike, but it doesn’t guarantee your bike won’t be stolen.
Qualified bike locks and secure parking location are still
needed.
