Like all multi-option digital equipment today the remote pretty much runs everything on the Sherwood R904-N. But although the Manual holds everything you need to use the remote it may not present it in the order you want or are used to. Pressing buttons before knowing what's happening when you do can delay your enjoyment of the first test. Multi-purpose buttons and button sequence takes a while to learn but is quite logical when you get used to them.
I caused myself unnecessary frustration by random clicking and accidentally activating the "remote select" for the TV. So make sure when you want to run the Sherwood that you've clicked the AVR button so your clicks are sent to it.
The easiest way I found for starting to test things out was to get the radio up and running. My button sequence as this:
1. AVR - makes the remote run the Sherwood
2. Tuner - makes the tuner the input
3. Enter - starts auto-tune sequence to find local FM stations and store them.
4. - Preset + - Clicks through your preset FM stations.
5. - If you have sound by this time you feel more confident to try out the TV, DVD, etc. With those devices just be aware that you can assign the audio input used for each device including -H HDMI, c COAX, o OPTICAL, a ANALOG. The options on how those things work are multitude and may be familiar to some and challenging for others. Just keep the manual handy and learn the versatility.
OH, by the way. Most people never take advantage of the downloaded PDF versions of equipment manuals to do key word searches when they become frustrated finding the "how to" on some feature. I use them all the time and that search feature has come in handy a lot.
Here's the diagram for the remote I grabbed from that PDF version:
