The big left knob adjusts the volume (practice), the right selection of the source (less practical). The CD loading is done from above, I think it is better than per drawer since the lens is available for possible cleaning. 40 programmable stations (20 FM and 20 MW), there are no numeric keys thereby selection is through the [up and down arrow]. The auto mode automatically searches and the program stations with a long press (not that much actually) Prog. Please note if you press on through inadvertently all previously stored stations are erased, it happened to me twice what is particularly annoying having to start over. He found me 7 when I have programmed in 15 manual. The USB (ID3 tag on CD and USB) .is really a more even with the navigation faults due to USB. The USB port and the on / off button is located right next to the bass boost button, headphone jack and input IN the left side (a Jack / Jack 3.5 cable is supplied) No clock and alarm function but a sleep timer. It runs on batteries (8 X LR 20 not included) and sector, remote control with button battery CR 2025 (included). The manual looks more like a road map to a notice, inconvenient but we did not read every day. It is written to prefer an external FM antenna but no decision of this type on the device, the limit! I find the sound pretty good and powerful enough to listen to music in the living room, perhaps just for a bit into the club, though ... In short, overall a good device but I liked better sensitivity tuner (since I live in the countryside) and the RDS. Rest reliability, the first I received the USB did not work '.
