The model number of the remote is of no help.
You need the model number of the opener. It is on the opener label.
And with that model number the you can sometimes google it and find a manual.
Or find a replacement control board that you can cross reference Chamberlain model and get the manual for the Chamberlain.
But all of the models for a number of years have had the same basic features and adjustment.
The main difference is they change the remote frequency a couple of years ago, versions with standby batteries, and different control panels. And cosmetics.
Pick the one closes to yours.
