Well, in that case it seems that both units have their pin code protection activated.
The use of a PIN code means that if your BeoSound 1 is disconnected from the mains for more than 30 minutes, the system can only be activated again by keying in your own personal PIN code. If the PIN code is not entered, the BeoSound 1 automatically switches to standby after 3 minutes. If a wrong PIN code is entered, you get five attempts to key in the code, after which the system is switched off and cannot be switched on for 3 hours.
