Delta faucet - Can't find set screws

[Glen4cindy]

I've got a Delta faucet in my bathroom that I need to get new cartridges for.

I'm not even sure which Delta faucet this is. I've tried to use their site to identify it but most of the photos are not working which is making it impossible to use.

I can't find any "buttons" or covers or little hidden anything that might reveal how these handles come off so I can start getting the cartridges out.

Any help would be appreciated.

Thanks in advance.

The valve is covered by Delta's warranty.
The valve assembly is removed by unscrewing the entire escutcheon under the handle.
