Hensoldt RSA-S - instructions?

[superlative]

Some questions on the Hensoldt RSA-S:

1. how do you switch to the manual mode?
2. once in the manual mode, how do you adjust the brightness?
3. how do you get out of manual mode?
4. how long does the red dot stay on before it switches off automatically?
5. how can I prolong the stay-on time?

Thanks!
