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 the Lenovo Phone is designed, tested, and manufactured to comply
with regulations governing radio frequency emissions, such emissions from the Lenovo Phone can
negatively affect the operation of other electronic equipment, causing them to malfunction. Turn off the
Lenovo Phone or use Airplane Mode to turn off the Lenovo Phone wireless transmitters when use is
prohibited, such as while traveling in aircraft, or when asked to do so by authorities.
Medical devices
The Lenovo Phone contains radios that emit electromagnetic fields. These electromagnetic fields may
interfere with pacemakers or other medical devices. If you wear a pacemaker, maintain at least 15 cm (6
inches) of separation between your pacemaker and the Lenovo Phone. If you suspect the Lenovo Phone is
interfering with your pacemaker or any other medical device, stop using the Lenovo Phone and consult your
physician for information specific to your medical device.
