I have a Alpine SEC-150R. My problem is that somehow i put it in another mode or something and the little LED light flashes once per second when the system is DISarmed and goes solid when the system is ARMed. Also the radar sensors don't seem to be on either....at least it doesn't chirp when motion goes by when usually it should.

The alarm isn't broken. I think I just put it in the wrong mode or something. I checked the owners manual I got from Alpine's site for the unit but could not find anything about the solid light state when armed.

Here's what I do know:

I know it's not in valet mode.
I know it is in Warning mode (it chirps when motion is near it in a certain parameter for more than 5 seconds etc.)

The unit was installed by a professional shop and I've used it with no problems for 5 months now. Again the unit is not broken...I just set it in the wrong mode I think.

If anyone knows what this solid LED light state means and how I can go back to my original settings (where LED light blinks once per second when armed and none when disarmed) please let me know asap.

Thanks in advance,
Charles
