Let's confirm which device you have. The Roku Express doesn't come with a Voice Remote (the one's that you pair). It comes with a simple IR remote. No pairing involved. So, let's find out which device it is that you have.
Go to Settings > System > About
The model number and software version/build will be helpful.
