Hello da_redhot_su,

Make sure that the "MUTE" button on the upper left of the volume control is operating properly. Sometimes a button will get stuck.

If that does not work, there's something wrong internally and you need to take the receiver to your audio dealer for repair.

Hope this helps.

How to open mirage island?


There's a man in Pacifidlog Town in the house southeast of the Pokemon Center who will tell you if he can see Mirage Island. If he sees it, it's there. Take each and every one of your Pokemon to this man every single day until he sees Mirage Island. Then go splurge.

Kenwood Car music system Tel Mute problem


Hi,

To my knowledge, some Kenwood head units have a wire specifically for this purpose, to mute the stereo in the event of an incoming mobile call. This would be the brown wire. Normally when not connected to a mobile phone, this wire is shielded/covered. It it was inadvertently exposed and touches any metal part, then it would enable the muting. If the wire is covered and not grounding, then an internal fault exists and most likely the trigger inside where the brown wire leads to.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
