HT-X1 Troubleshooting chart (continued) References " Tuner Symptom The radio makes unusual noises continuously. The preset channel cannot be recalled. Possible cause ! Is the system placed near the TV or computer? ! Is the FM antenna or AM loop antenna placed properly? Move the antenna away from the AC power cord if it's located nearby. ! Did you remove the plug from the wall jack, or did a power failure occur? Set the channel again. " Remote control Symptom The remote control does not operate. The system cannot be turned on with the remote control. Possible cause ! Is the battery polarity correct? ! Are the batteries dead? ! Is the distance or angle incorrect? ! Are there any obstructions in front of the main unit? ! Is the remote control sensor exposed to strong light (inverter fluorescent light, direct sunlight, etc.)? ! Is the remote control for another equipment used simultaneously? ! Is the AC power cord of the subwoofer/amplifier unit plugged in? ! Are the batteries inserted? " Condensation Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet (laser pickup, etc.) or on the transmitter on the remote control. Condensation may cause the system to malfunction. If this happens, leave the power on with no disc in the system until normal playback is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before operating the system. " If trouble occurs When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction. If such a problem occurs, do the following: 1 Set the system to the stand-by mode and turn the power on again. 2 If the system is not restored in the previous operation, unplug and plug in the subwoofer/amplifier unit, and then turn the power on. Note: If neither operation above restores the system, clear all the memory by resetting it. " Clearing all the memory (reset) 1 Press the ON/STAND-BY button to enter the power stand-by mode. 2 While pressing down the button and the FUNCTION button, press the ON/STAND-BY button until "SYS RESTORE" appears. Caution: When you reset, all data is deleted and the settings return to the default. (DVD initial settings are retained.) 64
