Tip & How-To about Cell Phones


`Your Nokia cell phone can be programmed to pick up radar speed traps, when programmed your cell phone picks up the radar and alerts you on the message alert tone.

1. Enter your menu
2. Select settings
3. Select security settings
4. Select closed user group
5. Select on
6. Enter 00000
7. Press ok
8. Clear back to normal, within a few seconds your phone will display a radar sign with five zero's next to it. It is now activated.

Unfortunately only Nokia phones have this function. Cell info display needs to be de-activated. Settings -> Phone Settings -> Cell Info display
Each time you turn off your phone, or even each time you loose contact with your carrier, you´ll have to activate it again... It is done by steps 1 through 5, but the number (00000) will be already on the field as default. If you put the number 500 in the closed user group, and you go out of a store with detection ports thy will go off.

#746025625# says SIM CLOCK STOP ALLOWED or similar, depending on your SIM card. Newer SIMs have a feature called 'clock stopping' that allows the phone to save energy -- it is a kind of sleep mode for SIM cards. Not all versions of software support this. You cannot turn the SIM clock on and off, the phone will do it automatically if the SIM supports clock stopping.

What does K band and x band mean for radar functions

They are different frequencies that the police radar guns can use.
  • X Band, 10.500 - 10.550 GHz
  • K Band, 24.050 - 24.250 GHz
In the same way that you can have different radio stations that are different frequencies, there are different radar guns that use different frequencies to determine your speed. Radar detectors are designed to pick up these frequencies to alert you when one may be in use in the area.

my valentine one will not pick up speed camera vans now it was working on KA band then went to K band now will not pick up?

They are using instant-on radar that has a weak K-band signal that is used to turn on the radar when you are in range. The signal is so weak that you cant detect it until you are in range of the main radar set. This is also known as radar detector countermeasures. Laser is worse. I have beaten laser twice with my Valentine 1 in California where it requires 2 reads to nail you. Slam on the brakes when your detector alerts..
