V. PRECAUTIONS
Temperature
LIVALL kids bike helmet consists of intelligent electronic system, plastics, EPS foam, etc. And the intelligent
electronic system contains polymer battery. Therefore, like other consuming electronic products, it requires
certain environmental temperature and has some limit in temperature changes.
1)Please don't use the helmet at high temperature that is over 150°F (65.6°C). Long-time using is forbidden,
otherwise the helmet will be damaged and lose its nature of safety.
When the outdoor temperature is high, please put the kids bike helmet at room temperature or in cool
environment instead of vehicles or storage bag that may cause higher temperature. In case of bubbling,
pits or misshaping on the surface of the helmet and EPS foam due to high temperature, the helmet's nature
of safety will greatly drop. If this happens, please discard this helmet immediately and replace it with a new
one;
2) When the outdoor temperature is lower than 32°F (0°C), please keep the kids bike helmet indoor. Neither
long-time outdoor placement nor use is suggested.
In case sudden change in temperature may occur, try not to use a helmet; if you must use, you should leave
a transition time for the helmet to adapt to the environmental change.
When used at the above temperature or with sudden change in temperature, the helmet may suddenly
shut down or cannot be powered on, which is a normal phenomenon. Please do not continue to use the
helmet in such environment so as to avoid damage to the battery.
Therefore, to ensure a proper use of the helmet, please carefully read this Instruction before use so as to get
to know the features, performance, wearing, maintenance and other aspects of the helmet.

Safety Precautions
This helmet is designed to burden damages and injuries from external impact. Although such injury may
seem minor, it could damage the helmet. If the helmet is damaged from falling or other causes, please
discard the helmet and replace it with a new one. Some accidents are unavoidable for whatever kids bike
helmet and the damaging degree may dier from the impacting; even at a slow speed, severe head injuries
or life threatening damages may incur. So please make sure that you've completely and carefully read this
Instruction and have arranged all possible protections before riding the bike, scooter or wearing the roller
skates.
Cautions
This kids bike helmet is specially designed for bikes, so please don't use it on other mobile vehicles, such as
motor cars, motor bikes, etc. No kids bike helmet can completely avoid all unpredicted impacts, but for the
best protection eect, the size of the helmet must be proper and the buckle must be tightly buckled. Unless
advised by the manufacturer, please refrain from modifying or removing any part of the helmet. This helmet
should not be used by children who climb or practice other activities which imply a risk to the child of falling
or of remaining hanging when the child is trapped by the helmet.
There is no helmet that can protect the user from all the injuries.
The strap should be xed at your chin when you wear the helmet.
You need to choose the helmet with the right size and use it correctly. Check whether the helmet suits your
head according to the instructions on comfort adjustment. Try to move the helmet to and fro after the strap

sights or backward to expose your forehead.
No other objects can be attached on the helmet except the ones suggested by the manufacturer.
