I've rendered my Sangean MMR-88 DAB radio (alias Sangean Survivor DAB+) unusable by selecting SystemSoftware Upgrade.

The display says "PC wizard.." and the radio is unresponsive. I've tried pressing and holding the power button for a couple of seconds, hoping that this would cause a hard reset, but that's not what happened.

How do I make my radio work again?


The solution was to remove the battery from the battery compartment at the bottom of the radio. This turned off the radio. After turning the radio on, it's responsive again.

Mind that for this to work, the radio mustn't be connected to another power source with a USB cable. Meaning you should unplug the radio before removing the battery so it actually turns off.

This trick is not described in the part of the manual that talks about software upgrades.

    @CharlieBrumbaugh: Yeah I know :-D But I was assuming that removing the battery would not turn that thing off due to its solar panel. Also, when the radio is charging using a USB cable, removing the battery doesn't in fact turn the radio off, so how to turn the device off is actually the core of my answer^^. – Matthias Braun Nov 1 '18 at 14:38
