Changing Line Signal BlackBerry Being Numbers

Most of the phones have five lines that show the signal strength of wirelessnetworks, whether GSM or GPRS. Likewise on the BlackBerry.

But you know that the 5-line signals can be converted to numbers? The figureshows the signal strength of the Blackberry in units of decibels per milliwatt(dBm).

It is very easy:
Press and hold ALT, then type 'NMLL'. The five signal lines will be instantlytransformed into a number that indicates the unit dBm.
Numbers -45 to -85 signal indicates 'strong'. When the numbers exceed -85to the -100, meaning the signal will be weaker.
To restore the display signal lines, simply do the same thing. Remember:Press and hold ALT, then type 'NMLL'.
