Samsung UN60d7000 Reset and Pairing Double Sided Remote QWERTY Side
This seems to be a repeating issue, so quickly posting instructions on how to reset and re-pair the Samsung double sided remote on the QWERTY side.
@ + Backspace (hold a few seconds until indicates RESET).
Flip over to "normal" non-qwerty side, and hit "Mute", 0 (zero), Mute, 0.
Flip back to the qwerty side and while holding remote close to TV (or even up to the back side of the TV),
hold SYM + Tab for a few seconds, then release, then wait to see if shows "Paired".
Hope that helps.
