However, when this happens, not only can I see that it is set to 'OFF' but there is also no loudspeaker icon showing on the screen. I have made a video to illustrate the problem which can be found here: [url]https://youtu.be/NhmiKRZYzSo[/url]. I have found that to reset the device it is not necessary to change the loudspeaker setting - simply to view it. To do this I simply follow this sequence: Enter, Enter, Enter, Back, Back.
