Broadlink RM4 Pro Device Help

I got one of these delivered yesterday and started setting it up this morning.

So far I am o for 3 of my devices in the database. I keep getting no devices founds when I click Arcam or JVC or HDFurry.

For the JVC RS420 I don’t have the original remote to do it manually and I don’t have one for the HDFurry.

Is there any way to get the remote codes in here without the remote?

The reason I went with the Broadlink is because it supports RF and I have a couple RF items I was going to program for the Theater.

Thanks

Try all other model JVC projector remotes from the unofficial remotes.
When I do Not have the physical remote I try all other remotes and I always finally found a working one.

Or buy a new remote - there seem to be loads on Ebay for around £10.00. You’re not going to be able to get the codes into the RM4 without one.
