508d Dual Radar Sensor Adjustment

Always adjust the inner/outer preimeter the same way you can only got a liitle less or more. Most of the time it's fine.  Sometimes when the interior is too much I will turn it down a tad.

Counter clockwise is less sensitive.

[QUOTE=rblack7754]Okay, first off thanks for your reply, perhaps it would be best to turn both settings all the way counter clockwise and then start with just the outer zone setting, the problem I have had is to many times it has set off the alarm far away from the windows, and when I turn it down I must go to far as it then doesn't go off at all, even reaching into the vehicle. [/QUOTE

Or you can try have it in the middle on both inner and outer settings. If you have the black wire grounded or using the ground out of the alarm system?

I would do is test it using and looking at the leds green and red.

Is you car a convertible?

Where is the 508d sensor mounted?  A good location if you have a problem getting a good center location is mounting the 508d under the headliner.

You have tinted windows?  If you did not know tint usually have metal and the 508d will not pass through so falsing will not be an issue unless it's really sensitive it will pass through the front.

You can do that but you know the npc (nuisance prevention circuit) will activate after 4 times triggering the alarm system.
