This section contains important safety, regulatory and handling information
for your phone. Complete information, including recycling and environmental
information, is provided in the Regulatory Notice.
Reading first — regulatory information
Be sure to read the Regulatory Notice for your country or region before using
the wireless devices contained in your Mobile Phone. To obtain a PDF version
of the Regulatory Notice, see the “Downloading publications” section.
Operating temperature
Use your phone only in the temperature range of -10°C (14 °F) — 40°C (104°F)
to avoid damage.
General battery notice
Batteries supplied by Lenovo for use with your phone have been tested for
compatibility and should only be replaced with approved parts. Dispose of used
batteries according to the instructions.
CAUTION:
- Risk of explosion if the battery is replaced with an incorrect type.
- Do not attempt to replace the internal rechargeable lithium ion battery. Contact Lenovo Support for factory replacement.
Charging
Lenovo is not responsible for the performance or safety of products not
manufactured or approved by Lenovo. Use only Lenovo-approved ac adapters and
batteries. Adapters shall be installed near the equipment and shall be easily
accessible.
Preventing hearing damage
CAUTION:
Excessive sound pressure from earphones and headphones can cause hearing loss.
Disposing according to local laws and regulations
When your phone reaches the end of its useful life, do not crush, incinerate,
immerse in water, or dispose of the phone in any manner contrary to local laws
and regulations. Some internal parts contain substances that can explode,
leak, or have an adverse environmental effect if disposed of incorrectly.
Radio and Telecommunications Terminal Equipment Directive
Lenovo declares that this product is in compliance with:
- The essential requirements and other relevant provisions of the Radio and Telecommunications Terminal Equipment Directive, 1999/5/EC
- All other relevant EU directives

frequency band. The Declaration of Conformity information is located in the
Regulatory Notice. To obtain a PDF version of the Regulatory Notice, see the
“Downloading publications” section.
Important WEEE information
Specific Absorption Rate information
Your mobile phone is a radio transmitter and receiver. It meets the government’s requirements for exposure to radio waves. The exposure standard for mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The India SAR limit for mobile phones is 1.6 W/kg averaged over 1 gram of tissue. Tests for SAR are conducted using standard operating positions with the phone transmitting at its highest certified power level in all tested frequency bands. The highest SAR value for your phone when tested for use at the head and body is outlined as follows:
| Position | The highest SAR value | Regulation |
|---|---|---|
| Head | 0.460 W/kg | India 1g SAR Limit (1.6 W/kg) |
| Body-worn | 0.733 W/kg |
During use, the actual SAR values for this phone are usually well below the
values stated above. This is because, for purposes of system efficiency and to
minimize interference on the network, the operating power of your mobile phone
is automatically decreased when full power is not needed for the call. The
lower the power output of the phone, the lower its SAR value.
To meet RF exposure guidelines during body-worn operation, the phone must be
positioned at least 1.5 cm away from your body.
Precautionary guidelines for mobile users
Mobile users are advised to take precautionary measures while using a mobile
handset as:
- Keep distance – Hold the cell phone away from body to the extent possible.
- Use a headset (wired or Bluetooth) to keep the handset away from your head.
- Do not press the phone handset against your head. Radio Frequency (RF) energy is inversely proportional to the square of the distance from the source — being very close increases energy absorption much more.
- Limit the length of mobile calls.
- Use text as compared to voice wherever possible.
- Put the cell phone on speaker mode.
- If the radio signal is weak, a mobile phone will increase its transmission power. Find a strong signal and avoid movement – Use your phone where reception is good.
- Metal & water are good conductors of radio waves so avoid using a mobile phone while wearing metal-framed glasses or having wet hair.
- Let the call connect before putting the handset on your ear or start speaking and listening – A mobile phone first makes the communication at higher power and then reduces power to an adequate level. More power is radiated during call connecting time.
- If you have a choice, use a landline (wired) phone, not a mobile phone.
- When your phone is ON, don’t carry it in chest/breast or pants pocket. When a mobile phone is ON, it automatically transmits at high power every one or two minutes to check (poll) the network.
- Reduce mobile phone use by children as a younger person will likely have a longer lifetime exposure to radiation from cell phones.
- People having active medical implants should preferably keep the cell phone at least 15 cm away from the implant.
