The sound of my wireless speakers suddenly is distorted

There could be various reasons that could cause sound distortion to your wireless speakers and they are as follows: * Make sure Bluetooth transmission (example: bluetooth file sending from phone to phone) is not performed within the area of the Home Theater System as it will cause interruption to the wireless signals. * Change the channel on the HTS to see if the problem persists: 1. Press OPTIONS. [ General Setup ] menu is displayed. 2. Press down to select [ Audio Setup ], then press right. 3. Select [ Wireless], then press OK. 4. Select [ Switch Channel ], then select the channel you wish to change into.
