Thanks for the response.
For me, the remote starts pairing almost immediately I press and hold the home button as I see the volime ring starts circling..
Next I hold the remote against the front panel. It continues circling for few more seconds and then the light disappears.
I tried this with 3 positions - holding the back of the remote against the front panel, holding front of the remote against the front panel and holding the head of the remote against the front panel. The corcling happens for few more seconds and then the light disappers.
By the way, I was able to connect the Naim's ios app with the atom. And right now it is connected with Naim app. Not sure whether that creates the problem.
I tried pairing also after putting atom in deep sleep and then waking it up. I tried the same pairing steps after atom goes back to the home screen. But no luck.
