I suspect that if you are using a cordless keyboard; that as most of these
do; it operates on 2.4GHz and for some reason, the CPU or other chips in
the PTR1 are generating enough RF to cause a harmonic that happens to be
in the frequency-range that your keyboard uses. Either it is being
induced through the case through you to the keyboard, or its position just
happens to be such that the RF from the PTR1 is enough when it is in that
position to sufficiently degrade the quality of the link. If you move the
receiving part of the keyboard setup which is plugged into your computer
to a different position; can you eliminate the problem?

Hi all,
I'm by no means any kind of electrical engineer, but I have noticed an odd
coincidence when using my PTR1. Whenever I'm reading using the p1 and I come
across a term I would like to define, I place the p1 on my lap and I reach
over to grab my wireless keyboard. When trying to type I notice that I will
not get any audio from my computer. I then take the p1 off my lap and place
it on my desk away from my body. I am then able to type and hear the audio
feedback of what I'm typing. If I then place the p1 on my lap once again, I
can no longer type or hear any audio via my wireless keyboard. If I place
the P1 away from my body I will be able to type. Is there some sort of
grounding issue with the P1? My body is obviously conducting some sort of
static interference. This does not happen with any of my note takers,
Trekker, or any other electronic device including remote controls and so on.
I don't think I'm crazy because I can repeat this anomaly over and over just
as I've described above.
