Combro 625 Chrony

[Hunter2011]

Hi guys.
I totally forgot I've got a Combro 625 Chrony. I used it llong ago. So I wanted to test the speed of my still standard 2240 with various pellets. But guess what, it does not want to work anymore, it does come on but does not show the speed.
Where can I possibly start to look for the problem?

A fresh battery might be a good idea if in fact uses one make sure the pick ups are clean I really don't know your chrony but this is what I would check on mine.

Make sure you are about 3 foot away and the lighting is ok ....

He he you don't know this chrony.
It attaches to the barrel of your pistol/rifle. It works even indoors.
I will try the battery, I thought it is fine as it does come on.
