Important safety and handling Information

Plastic bag notice  Danger: Plastic bags can be dangerous. Keep plastic bags away from babies and children to avoid danger of suffocation.Caution about high volume usageWarning: Exposure to loud noise from any source for extended periods of time may affect your hearing. The louder the sound, the less time is required before your hearing could be affected. To protect your hearing:

  • Limit the amount of time you use headsets or headphones at high volume. ·
  • Avoid turning up the volume to block out noisy surroundings.
  • Turn the volume down if you can’t hear people speaking near you.

If you experience hearing discomfort, including the sensation of pressure or fullness in your ears, ringing in your ears or muffled speech, you should stop listening to the device through your headset or headphones and have your hearing checked.

To prevent possible hearing damage, do not listen at high volume levels for long periods.

Safety instructions for parents and adult supervisors

Your mobile device is not a toy. As with all electrical products, precautions should be observed during handling and using of electrical products to reduce the risk of electric shock. If parents choose to allow children to use the device, they should caution his or her child about the potential hazard while using and handling the mobile device. Parents should inspect the mobile device (including the ac power adapter and the small part, as applicable) periodically for damage. Routinely check this mobile device to ensure that the device is working properly and is safe for children to use.

Internal rechargeable battery warningDanger: Do not attempt to replace the internal rechargeable lithium ion battery. Replacing the original battery with an incompatible type may result in an increased risk of personal injury or property damage due to explosion, excessive heat, or other risks. Do not attempt to disassemble or modify the battery pack. Attempting to do so can cause a harmful explosion or battery fluid leakage. When disposing of the battery, comply with all relevant local ordinances or regulations. Do not dispose the battery pack in municipal waste. Dispose used batteries according to the instructions. The battery pack contains a small amount of harmful substances.To avoid injury:

  • Keep the battery pack away from open flames or other heat sources.
  • Do not expose the battery pack to water, rain, or other corrosive liquids.
  • Do not leave the battery in an environment with extremely high temperature.
  • Avoid short-circuiting the battery pack.
  • Keep the battery pack out of reach of small children and pets.
  • Do not leave the battery in an environment with extremely low air pressure. It may result in an explosion or the leakage of flammable liquid or gas from the battery.

To extend battery life, we recommend charging the battery to at least 30% to 50% capacity each time, and recharging it every three months to prevent over discharge.

Specific Absorption Rate information

YOUR MOBILE DEVICE MEETS INTERNATIONAL GUIDELINES FOR EXPOSURE TO RADIO WAVES.Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves (radio frequency electromagnetic fields) recommended by international guidelines. The guidelines were developed by an independent scientific organization (ICNIRP) and include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The radio wave exposure guidelines use a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit for mobile devices is 2W/kg. Tests for SAR are conducted using standard operating positions with the device transmitting at its highest certified power level in all tested frequency bands. The highest SAR values under the ICNIRP guidelines for your device model are listed below:

Maximum SAR for this model and conditions under which it was recorded.

Europe 10g SAR Limit (2.0 W/kg) Lenovo CT- X636F


WLAN, Bluetooth

0.665 W/Kg

During use, the actual SAR values for your device are usually well below the values stated. This is because, for purposes of system efficiency and to minimize interference on the network, the operating power of your mobile device is automatically decreased when full power is not needed for the data connection. The lower the power output of the device, the lower its SAR value. If you are interested in further reducing your RF exposure then you can easily do so by limiting your usage or simply using a hands-free kit to keep the device away from the body.
