Then rotate the volume control to move between dimmer ON and OFF.&nbsp; Finally press and hold the select button again to exit the setup.</P><P>Hope this helps.</P></BODY></HTML> Thu, 15 Dec 2011 18:00:53 GMT Drumzman 2011-12-15T18:00:53Z CDX-GT540UI https://community.sony.ba/t5/portable-audio/cdx-gt540ui/m-p/271837#M19 <HTML><HEAD></HEAD><BODY><P><SPAN style="color: #000080; font-size: 12pt; ">Hi There</SPAN></P><P><SPAN style="color: #000080; font-size: 12pt; "><BR /></SPAN></P><P><SPAN style="color: #000080; font-size: 12pt; ">The blue colour of the face is too bright at night, how can it be dimmed, please?</SPAN></P><P><SPAN style="color: #000080; font-size: 12pt; "><BR /></SPAN></P><P><SPAN style="color: #000080; font-size: 12pt; "> <EM>Bruce</EM></SPAN></P></BODY></HTML> Mon, 05 Dec 2011 20:36:24 GMT https://community.sony.ba/t5/portable-audio/cdx-gt540ui/m-p/271837#M19 CATFISH4U 2011-12-05T20:36:24Z CDX-GT540UI https://community.sony.ba/t5/portable-audio/cdx-gt540ui/m-p/271838#M20 <HTML><HEAD></HEAD><BODY><P>Hi Bruce,</P><P></P><P>I think there's a display dimmer function on this unit - press and hold the 'select' button until the setup display appears - then keeping pressing the select button repeatedly to get to the setting you want to adjust (in this case 'DIM' for the dimmer).
