and the safety of others. Follow the law. Local laws and regulations might govern how you can use
mobile electronic devices, such as Lenovo Phone, while you drive a motor vehicle or ride a bicycle.
Choking hazard

can be a choking hazard to small children. Additionally, the glass screen can break or crack if dropped
on or thrown against a hard surface.
Explosive atmospheres

powders). Obey all signs and instructions.
Radio frequency interference
Observe signs and notices that prohibit or restrict the use of mobile phones (for example, in healthcare
facilities or blasting areas). Although Lenovo Phone is designed, tested, and manufactured to comply
with regulations governing radio frequency emissions, such emissions from Lenovo Phone can

high-voltage environments, such as electric appliances, electric heating equipment, or electric cooking
equipment. Use Lenovo Phone only in the temperature range of -10°C (14 °F)—45°C (113 °F) to avoid
damage.
When Lenovo Phone is turned on or the battery is charging, some parts might become hot. The
temperature that they reach depends on the amount of system activity and the battery charge level.

Avoid keeping your hands, your lap, or any other part of your body in contact with a hot section of
Lenovo Phone for any extended time.
Protecting your data and software

Be aware that accessing network resources can leave Lenovo Phone vulnerable to computer viruses,
hackers, spyware, and other malicious activities that might damage Lenovo Phone, software, or data. It
is your responsibility to ensure that you have adequate protection in the form of firewalls, antivirus
software, and anti-spyware software and keep such software up to date.
Keep electrical appliances away from Lenovo Phone, such as an electric fan, a radio, high-powered
