Solo2 after a timer box is going to deep standby

Hello,

last time I've strange problems. Solo2 is in deep standby, a timer wakes up, box is record this timer in standby (Advanced Startup to Standby) than I go to watch TV while record is running. If this timer record ready, Box is going to deep standby!? Btw. problem at two Solo2.

Normaly there was a Message "timer is runing, do you like to switch off" or so. This message I switched away and watch TV while timer is running and after the timer Box isn't going to deep.

Every timer is set to:

After event: automatic

Any idea?

Thanks and regards
