Problem No sound is coming from the subwoofer. (The indicator on the subwoofer flashes or the STANDBY indicator on the subwoofer glows.) Though the indicator on the subwoofer glows, little or no sound is coming from the subwoofer. The volume decreases when the unit is turned on. Cause The center unit and subwoofer are not connected due to a bad wireless communication status. The center unit and subwoofer are not paired. The volume is too low. The front side of the subwoofer is blocked. The playback source does not contain low-frequency signals. The automatic volume adjustment function is activated. To prevent excessive loudness, the unit automatically controls its volume within a certain level when the unit is turned on. Remedy Move the subwoofer closer to the center unit. If the issue is not resolved, move the subwoofer to a location that supports better communication (one in which the indicator glows). If the communication between the center unit and subwoofer is obstructed by a metallic object or another object, change the position of the center unit and subwoofer or change the installation location of the subwoofer. If there is a device (microwave oven, wireless LAN, etc.) that emits radio frequency signals, move the center unit and subwoofer away from the device. Pair the center unit and subwoofer manually (p. 42). If a wireless connection is not established, the unit may be malfunctioning. Unplug the power cables from the AC wall outlets and contact the nearest authorized Yamaha dealer or service center. Turn up the volume of the subwoofer (p. 28). Clear the area around the front side and the bass reflex port of the subwoofer. Play back a sound source containing low-frequency signals, and confirm that the sound is output from the subwoofer. Turn up the volume as required (p. 28). En 39
