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

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.
