Hi. Royal do not export to us, so I don't have info on your model, but if you have left it off for too long, then it may have locked up, and need fully resetting. Do you have a manual?
Try this:
Take the batteries out again.
Turn off power at the wall over-night.
Turn key to reg mode, then turn pwer on at wall.
If machine comes on, then refit batteries.
If not, then you may need to find a full clear for it.
