  First, ensure that all connecting cords are correctly inserted into the input/output jacks of the receiver, speakers, and equipment. Then, verify that both the receiver and all connected equipment are powered on. Check that the MASTER VOLUME is not set to “VOL MIN”. Also, press MUTING on the remote to deactivate the muting function. Try selecting your equipment by pressing the input button on the remote or turning the INPUT SELECTOR on the receiver.
