The following details are struck me:
Built in very small power supply unit consumes 0.1W at idle (2,7VA) and can therefore easily for less than a year in electricity costs EUR constantly dwell in the socket. In operation the unit in DAB mode 1.5W (4,2VA) needs, at maximum volume more. It would be convenient if here a micro-USB power adapter would fit, as found in smartphones.
The manual indicates that the battery life is the FM and DAB mode at 25 hours. In a weekly useful life of 5 x 0.5 = 2.5 hours so you'd have ten weeks replace the batteries.
I come to the DAB scan at 21 stations.
If you switch the radio on a sensitive edge (in front of the power supply) that it "remembers" it is pleasant as the last station. However, it forgets what information was adjusted via button INFO / MENU. Had So the clock display selected, the first available information is displayed after power depending on the broadcaster.
After turning on the radio needs about five seconds to the first tone.
To turn to use the volume knob, so you have to adjust the volume each. As a push button would be more practical.
In addition to the accompanying multilingual leaflet in format A2 there is on the Internet very well-crafted documents to AE5020.
The user in the German language has 17 pages and leaves no question unanswered. In general, the technical specifications are comprehensive.
If I had a half a meter anschalte the AE5020 next to my PC, it has no DAB reception.
This can / will be up to radio interference of my PC.
Low tones listen to the AE5020 to my mind better, if you positioned the rear sound hole that can be reflected back sound emitted by furniture or window.
