5. Initialization (Differs according to destination) After executing the test mode, be sure to perform initialization. � For J/SP/AEP Version (Use this procedure) While pressing the AC-3 RF button and DIGITAL3 buttons simultaneously, press the POWER button. When the VOLUME LED starts blinking, release the buttons. �initialized (J/SP/AEP)� will be displayed on the fluorescent display tube, and all internal settings will be returned to the initial values. � For U/CA version (Do not use this procedure) While pressing the AC-3 RF button and DIGITAL4 buttons simultaneously, press the POWER button. When the VOLUME LED starts blinking, release the buttons. �initialized (U/CA)� will be displayed on the fluorescent display tube, and all internal settings will be returned to the initial values. NOTE: As all histories of abnormal DSP operations will be erased, note down the contents of the history beforehand. 6. Check of Pressing of Unintended Button � This check is always performed when the power is turned ON. Therefore when an error occurs, it can be known without setting the test mode because the VOLUME LED blinks and the fluorescent display tube stops displaying. � When an unintended button is pressed during the test mode or initialization, the VOLUME LED also blinks, and the fluorescent display tube stops displaying, preventing no mode to be set. 7. Other Functions In the personal use of the unit at home, if no sounds are produced due to DSP problems, the DSP will be rebooted automatically to attempt recovery. If no sounds are still produced after five retries, �Turn POWER SW off!� will be displayed on the fluorescent display tube. If this problem occurs, it indicates that the DSP is faulty or the user�s setting environment may be unsuitable. Refer to �3. SelfDiagnosis Mode for Servicing/Display of History of DSP Errors� on page 13 to identify the problems.
