TROUBLESHOOTING Problem DSP parameters and some other settings on this unit cannot be changed. "INPUT DATA ERR" appears on the display and no sound is heard. The sound field cannot be recorded. This unit does not operate properly. A source cannot be recorded by a tape deck or VCR connected to this unit. Noise from nearby TV or tuner. The sound is degraded when listening with the headphones connected to the compact disc player or tape deck that is connected with this unit. Cause The function "6. MEMORY GUARD" in the SET MENU mode is set to the "ON" position. A nonstandardized source is played back, or the unit playing back a source is misoperating. It is not possible to record the sound field on a tape deck connected to this unit's TAPE/MD OUT terminals. The internal microcomputer has been frozen by an external electric shock (lightning, excessive static electricity, etc.) or power supply with low voltage. The source unit is connected to this unit between digital terminals only. This unit is too close to the affected equipment. This unit is in the standby mode. What to Do Set to the "OFF" position. Check the source, or turn off the unit playing back the source and then turn on again. Unplug the AC power cord from the wall AC outlet, and then plug in again after about one minute. Make additional connection between analog terminals. Move the unit further away from the affected equipment. Turn the power to this unit on. Remote controller Problem The remote controller does not work. The remote controller does not function properly. Learning cannot be made successfully. (The TRANSMIT/LEARN indicator does not light up or flash.) Continuous functions such as volume are learned, but operate only for a moment before stopping. Cause The batteries of this remote controller are weak. The internal microcomputer "freezes". Wrong distance or angle. Direct sunlight or lighting (of an inverter type of fluorescent lamp etc.) is striking the remote control sensor of the main unit. The internal microcomputer "freezes". The batteries of this remote controller and/or the other remote controller are weak. The distance between the two remote controllers is too far or short. The signal coding or modulation of the other remote controller is not compatible with this remote controller. Memory capacity is full. The internal microcomputer "freezes". Learning process incomplete. What to Do Replace the batteries with new ones and press the RESET button on the remote controller. Press the RESET button on the remote controller. The remote controller will function from a maximum range of 6 meters, no more than 30 degrees off-axis from the front panel. Change position of the main unit. Press the RESET button on the remote controller. Replace the batteries (and press the RESET button for this remote controller). Place the remote controllers at the proper distance. Learning is not possible. Further learning is not possible without deleting unnecessary commands. Press the RESET button on the remote controller. Be sure to press and hold the function key on the other remote controller until the TRANSMIT/LEARN indicator begins flashing slowly. 72
