This command should be the only thing you need I think:
You can adjust the settings according to what you want. You can view the settings in the AT commands manual 14.7.
The R410 Should go into PSM automatically if it doesn't have anything to do.
I'm not 100% sure this works, I'm currently working with the N211 myself, which works a little bit different.
Reading all the available datasheets has helped me a lot.
