Or contact the maker.

Try putting it in a freezer for at least 45 minutes. For some reason the diode seems to respond to the condensate, and it keeps working even after it thaws. This worked for two laser diodes on my 5 point Stanley Fat Max after trying everything else.

I've never come across that with mine, but I have a couple thoughts that you might try ........

First, check and make sure there are no buttons stuck down. And the second thing is take the battery out for a minute or so and see if it clears it. In fact, you might also want to check the battery voltage. I suppose there's a chance that low voltage could do that??

Hope one of those helps!

Improper storage (I've done it too), usually means that the batteries have become too hot - and
therefore weak. The first thing I'd try is changing the batteries.
The 635nm laser operates on (4) AA batteries, and the rotary uses (1) 9V battery.
The online reviews for this a horrifically bad - see:

When the tool is level, the lasers will stop flashing, but check out the batteries too, because if they're weak, the tool will not level, and the lights will continue to flash .

That's usually a battery problem either in the laser unit or the remote control. The battery in the remote tends to disconnect if bumped. A small piece of foam pad at the bottom of the battery can fix that.

You can get the manual on the link below please give it time to download. It is a large file.

Good Luck and please rate 4 thumbs up for the free answer.

check with bosch or cst/berger. robotoolz is now owned by bosch and they have eliminated most of the robotoolz product line

I don't believe that the unit has a spinning laser. Mirrors are used to split the beam into several beams that indicate plumb, level and righ angles
