Talk:Guide to emergency Cell Phone tips

The site you posted claims some of them are false, but it looks like a reliable source. So i will Delete the false ones and keep the real ones, then i will remove the warning.

Here is what i read....

2 keyless entry http://www.snopes.com/autos/techno/keyless.asp also i am an electrical engineer and agree with the article. Cell phones transmit an audio range of frequency somewhere around 100Hz to 30kHz. key-less entry remotes operate on RF(not audio) at around 900MHz. It is possible that the RF signal can be passed through the mic, by the mic working as an antenna, but it would drop the signal strength to less than 1/100 of the original signal strength. After the mic all signals above ~30kHz are filtered out, so the 900MHz signal is gone.

3 http://www.snopes.com/inboxer/household/cellphones.asp they messed up the number code. its *#4720# to lower sound quality, and extend battery life, *3370# increases quality and lowers battery life (i will correct this)

looks like #4 and #5 are ok ZyMOS
