Can't Pair H3 Pen to Hi13

[Chris G]

Doesn’t have bluetooth like the MS surface pen so impossible to pair. When its close to the screen it should be detected and then work. The top isn’t a button like the Surface pen but another tip, which can be used to erase for example.

Chris:

Thanks. I tried putting the H3 pen close to the screen and actually touching the screen. Nothing happens from the tip of the pen.

But then when I turned it around, it actually works from the back of the pen. I can draw on the screen from the back. Ok I just tried the second pen. It works exactly the same way. The back of the pen can draw on the screen, but not the tip.

So why doesn’t the tip register? Is there a defect in the pen, or is there something I need to do either with the pen or the Hi13 to enable to tip to work?

My finger works fine to draw on the screen, as does a passive soft rubber tip stylus that I use on my old iPad. So I assume the digitizer built into the screen is working properly.

That is very strange, but it sounds like it must be a defect with the screen side? Hardware fault of sorts. Unless you got to faulty pens I find hard to believe.

Doesn’t it seem more likIely that both pens are bad? I presume the tech used in the tip and the back end of the pen are the same. If that is true, and the screen responds to the back end of the pen, which as you wrote, is just another pen tip, then it doesn’t seem that the screen could be at fault. The screen also responds perfectly to drawing with a finger and also with a passive stylus.

Hi Scott, I recommend that you should first check the battery polarity and make sure things are good from the pen side.

[Scott Bassett]

The battery polarity is correct (positive terminal facing down toward the tip of the pen, negative terminal toward the top end of the pen) according to the diagram actually printed on the battery itself.

I would try reversing the battery just as a test, but I wonder if that would damage the pen (not that it is working properly anyway)? It seems unlikely that the polarity should be reversed. The conductor inside the pen looks like it was made to contact the positive terminal and the conductor inside the cap looks like it was made to contact the negative battery terminal.

So are the pens working now?

Unfortunately, they are only half working. Only the back end of the pen can write on the screen. Writing on screen with the back end feels kind of odd because the back end is so blunt.

The tip, no matter how long I hold it against the screen, does not activate and will not write on the screen. This mystifies me.

I don’t think the pen has an eraser function as it doesn’t erase for me and I do not see any mention of it on their site unless I overlooked something.
