Hi I have been having problems with my computer. It only seems to happen after i ride to work, leave the bike for about 10 hrs then when i get on the bike to come home and turn on the computer it starts giving me multiple readings. The first one is that I'm going fast then the next one says that I'm going slower and it alternates between the two, and this is before I even start riding. As I start riding the speeds change but always alternate between two different speeds, one high and one low. They are nowhere near accurate to the speed I'm actually going. When i stop, they still flash and do not go to zero. I have changed the batteries but after a couple weeks they started again. The sensor on the wheel is aligned properly. Any thoughts?

Thanks, Richard

Oh and by the way, the computer model is a Filzer dB4lw, this is the webpage for it: https://www.filzer.com/products.php?id=7

Just a thought: Have tried resetting it? Or maybe removing the battery for some time and then reinstalling it?

My cell phone does that to my Wireless VDO 15+. I've had max readings in the 90's.
Take your computer off, with it on put your phone near the back of the computer. I have to move mine from top to bottom of the front of my phone to get it to go really wild.
Give it a try.
I leave my phone off till I want to use it.

I just tried that and it does the same thing!!!! Even my wireless mouse and keyboard affect it lol! Anything with a radio signal does!
The phone has to be pretty close though.
I think if I leave my phone in my pocket while riding, it won't interfere with the computer, will have to try it

I turn mine off.
