Operating temperature
Be aware of heat generated by Lenovo Phone. When using Lenovo Phone, keep
it away from hot or 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. Extended contact with your body, even
through clothing, could cause discomfort or even a skin burn. 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
Do not delete unknown files or change the name of files or directories that were
not created by you; otherwise, Lenovo Phone software might fail to work.
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 speakers, an air conditioner, and a microwave oven. The
strong magnetic fields generated by electrical appliances can damage the
screen and the data on Lenovo Phone.
