The unit runs for one hour after the alarm time. If you set the unit to 07:00, it will run until 08:00 and then turn off. With the second alarm, you can let the radio run for 2 hours...

It has 2 alarms that can be programmed to specific time and MO-FR or SA-SO or MO-SO. + DAB station and volume. If you don't turn the alarm off, I think it runs for 1 hour.

No you can't, there is no snooze function.
