IR remote for Q

Do the cheap generic IR remotes constantly update codes for newer cameras. It's just that the ones I have for K-r don't work the Q although the ones now listed include Q and K-r on same model. Presumably they have to update them?

I dont know the Q but Pentax have been using the same remote (Remote Control F) for 20 years for all their other cameras.

Page 101 of the manual says the remote will only work within 5cm at the rear. You sure you're close enough?

I bought a remote from China for my Kx last year. Works fine on both the K5 and the Q

I bought a JJC RM-E7 remote from ebay for a fiver inc delivery. Works fine on the K5 and the Q.

My £2 Chinese IR remote bought for the K5 works perfectly on the Q

Thanks for the useful info. I have three of these devices, all working with my K-r (and formerly K-x). I also have the JJC RM-4 and that is now working with the Q after changing the battery. The other two still don't but I think perhaps the coin batteries are low and perhaps the Q just needs that bit more power than the K-r. So basically solved and thanks.
