Store the phone out of the reach of little children. The phone may

cause injury if used as a toy.
Be aware of the usage limitation when using a mobile 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 standby mode, it still transmits radio
frequency (RF) energy; therefore power off your phone if required.
Do not touch the antenna while calling. Otherwise it will affect the

quality of calling and waste battery energy. The damaged antenna
will cause slight burn while touching your skin.
Do not put other things on the terminal to avoid overlaying radiator.

Keep the antenna free from obstructions and position the antenna

straight up. This will ensure best call quality.
