Specific Absorption Rate information
This mobile device meets the government’s requirements for exposure to radio
waves.
Your mobile device is a radio transmitter and receiver.
The exposure standard for mobile devices employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The India SAR limit for mobile
devices is 1.6 W/kg averaged over 1 grams of tissue. 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 value for your Lenovo device when tested for use at the head
and body is outlined as follows:
Position The highest SAR value Regulation
Head 1.192 India 1g SAR Limit(1.6W/kg)
17
1
Body-worn 0.215 India 1g SAR Limit(1.6W/kg)
During use, the actual SAR values for this device 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
devices is automatically decreased when full power is not needed for the call.
The lower the power output of the device, the lower its SAR value.
To meet RF exposure guidelines during body-worn operation, the device must
be positioned at least 1.5cm away from your body.
Precautionary Guidelines for mobile users
Mobile users are advised to take precautionary measures while using a mobile
handset as:
1. Keep distance – Hold the cell phone away from body to the extent possible.
2. Use a headset (wired or Bluetooth) to keep the handset away from your
head.
3. 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.
4. Limit the length of mobile calls.
5. Use text as compared to voice wherever possible.
6. Put the cell phone on speaker mode.
7. If the radio signal is weak, a mobile phone will increase its transmission
18
1
power. Find a strong signal and avoid movement – Use your phone where
reception is good.
8. Metal & water are good conductors of radio waves so avoid using a mobile
phone while wearing metal-framed glasses or having wet hair.
9. 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.
10. If you have a choice, use a landline (wired) phone, not a mobile phone.
11. 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.
12. Reduce mobile phone use by children as a younger person will likely have a
longer lifetime exposure to radiation from cell phones.
13. People having active medical implants should preferably keep the cell
phone at least 15 cm away from the implant.
