Questions about Roberts Revival iStream 3L

No, it is a 12V DC cable.

Hello, in Switzerland a country-specific two-pin power supply unit is supplied. At least that's how it was for me.

It is imitation leather, recognisable by its repeating structure. Well made.

Simply insert batteries in parallel with the power supply. And... the date and time are automatically synchronised with time servers via DAB or WiFi anyway.

According to our information, this is not possible.

Only the newer iStream 3 is still available on the Roberts website. The 3L is no longer available and has older WiFi and Bluetooth standards because of the older hardware. I can't say for sure whether this plays any role, as the specifications are not specified more precisely or are only available behind a paywall (sic!!!). But it is possible that certain Bluetooth functions of modern devices are not supported, for example new high fidelity transmissions for which BT 5.x is necessary. WiFi doesn't matter, as the new routers also support older standards and audio really doesn't take up any bandwidth.
