31 Rev.1.1 Troubleshooting Symptom Cause/solution No reception Does the POWER LED light? >> Check the connection between the receiver and the amplifier. Check the power of the amplifier is turned on Is the power of the microphone turned on (Is a battery loaded)? >> Turn on the power of the microphone (load a battery) to put it into the transmissible state. No sound generated Does the reception LED indicator MIC1 or MIC2 light? >> If the microphone is not normally receivable, the reception LED indicator does not light. The audio output of LINE IN is not provided. >> Is audio output of the device connected to LINE IN ready to be provided? No audio output of the microphone or LINE IN is provided. >> Is n’t the page mute signal input provided to this unit? If the page mute signal input is provided, the audio output from this unit is muted. The 3 LEDs of this unit light yellow while the page mute function is activated. Is the volume setting equipped in this unit set to the lowest level? >> The volume of the microphones MIC1 and MIC2 and LINE IN equipped in this unit can be adjusted by K-STD14 and through external communication control. The volume of the mixing output fluctuates. >> When the microphone override function is active, an audio input to the microphone (MIC1 or MIC2) attenuates the audio level provided to LINE IN. Audio interrupted Is n’t the feedback blocker activated? Adjust the speaker output to the lower level so as to avoid the feedback. LINK indicator ( red ) System Error >>Please ask an administrator. LINK indicator ( yellow blink ) The receiver is maintenance mode. >>Please ask an administrator.
