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.
