NOTES ABOUT THE REMOTE CONTROL TRANSMITTER Battery installation Remote control transmitter operation range 1 3 Remote control sensor 2 Battery replacement If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes q Use only AA, R6, UM-3 batteries for replacement. q Be sure the polarities are correct. (See the illustration inside the battery compartment.) q Remove the batteries if the remote control transmitter will not be used for an extended period of time. q If batteries leak, dispose of them immediately. Avoid touching the leaked material or letting it come in contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries. Within approximately 7 m (23 feet) 30° 30° Notes q There should be no large obstacles between the remote control transmitter and the main unit. q If the remote control sensor is directly illuminated by strong lighting (especially an inverter type of fluorescent lamp etc.), it might cause the remote control transmitter not to work correctly. In this case, reposition the main unit to avoid direct lighting. TROUBLESHOOTING If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help. SYMPTOM Power is not supplied even though the POWER switch is ON. No sound . Sound level is too low. The remote control transmitter does not work. The distance or range within which the remote control transmitter can be used decreases. 12 CAUSE The power plug is not securely connected. The VOLUME control is set to 0. The OUTPUT switch is OFF. Speaker cables are not connected securely. Speaker cables are connected incorrectly. Setting of the PHASE switch is not proper. A source sound with few bass frequencies is played. It is influenced by the standing waves. Direct sunlight or lighting (of an inverter type of flourescent lamp etc.) is striking the remote control sensor of the main unit. The batteries of this remote control transmitter are too weak. REMEDY Connect it securely. Turn the VOLUME control to right. Press the OUTPUT switch so that the OUTPUT indicator on the front panel illuminates. Connect them securely. Connect them correctly, that is to say L (left) to L, R (right) to R, "+" to "+" and "-" to "-". Set the switch to the other position. Play a source sound with bass frequencies. Set the HIGH-CUT control to a higher position. (Turn the knob to right.) Break up the parallel surface by placing bookshelves etc. along the walls. Change position of the main unit. Replace the batteries with new ones.
