Warning and Maintenance

• Some electronic devices are susceptible to electromagnetic interference sent by
the phone if inadequately shielded. Keep using the phone at least 20 cm or as far
away as you can from TV sets, radio and other automated office equipment so as
to avoid electromagnetic interference.
• Operating the phone may interfere with medical devices like hearing aides and
pacemakers, or other medical devices in hospital. Consult a physician or the
manufacturer of the medical device before using the phone.
• Be aware of the usage limitation when using the phone at places such as oil
warehouses, or chemical factories, where there are explosive gases or explosive
products being processed, because even if your phone is in idle state, it still
transmits radio frequency (RF) energy. Therefore, power off your phone if
required.
