Precautionary guidelines for mobile users

Mobile users are advised to take precautionary measures while using

a mobile handset, such as:

1. Keep distance – Hold the mobile phone away from your 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 greatly increases energy

absorption.

4. Limit the length of mobile calls.

5. Use text as compared to voice wherever possible.

6. Put the mobile 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 and water are good conductors of radio waves so avoid

using a mobile phone while wearing metal-framed glasses or when

your hair is wet.

9. Let the call connect before you put the handset to your ear or

start speaking and listening – A mobile phone first makes the

communication at higher power and then reduces the power to an

adequate level. More power is radiated while the call is connecting.

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 your chest/breast or

trouser 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 mobile

phones.

13. People with active medical implants should preferably keep the

mobile phone at least 15 cm away from the implant.
