Precautionary Guidelines for mobile usersMobile users are advised to take precautionary measures while using a mobilehandset 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 isinversely proportional to the square of the distance from the source -- being very closeincreases 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 astrong 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 phonewhile wearing metal-framed glasses or having wet hair.9. Let the call connect before putting the handset on your ear or start speaking andlistening – A mobile phone first makes the communication at higher power and thenreduces power to an adequate level. More power is radiated during call connectingtime.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 amobile phone is ON, it automatically transmits at high power every one or two minutesto check (poll) the network.12. Reduce mobile phone use by children as a younger person will likely have a longerlifetime exposure to radiation from cell phones.13.People having active medical implants should preferably keep the cell phone at least15 cm away from the implant.13
