Self-test when turned on....

[solaraguy]

I just installed some m-40's and was wondering if they were suppose to do that self-test (beep for a few seconds) when turned on everytime? Mine do not beep every single time I turn them on, but most of the time they do. Any idea if this is normal or is there something wrong?

Thanks

they should beep (screech) for a few seconds each time you turn them on, and if they are the latest ones they will beep again in about 30 seconds after the "self test" period is up.

when they don't beep, can you still see the led go from red to green?

If they don't beep I would considering sending your units in for repair...I know when my lidateks don't do the self test beep something is wrong

I figured it out. I had them turned off when I started up the car. So when I flipped the switch on they wouldn't beep, but if I shut them off and turned then on again they would.

So I tried leaving the switch in the on position when starting the car and they beeped. They also do the beep after 30 seconds. I was wondering why it was beeping all the time like that after them going on lol. What is the reason for the 30-second beep after they are on?

glad it was an easy fix.

within the the first 30 seconds it alllows you to do a self test.
meaning normally if you point something like a tv remote at it, they won't alert, but during the first 30 seconds it will, letting you know that they are working properly.

it's an easy alternative to buying a laser tester or waiting until you find a laser trap to know they are functioning.

I see, thank you so much for that information. Appreciate it.

I found a faulty head on my 1 year old blinder M40 (old software)
I have replaced the 1 head with a new one, which now has the 30 second tone after start up. Will it be OK to run 3 old heads and 1 new head?
Will they all work the same?
What advatage/disadvatage does the new head have?
thanks a lot, Bruce
