SECTION 4 TEST MODE

Initialization Mode All preset contents are cleared when this mode is activated. When returning the unit to the customer after completing repairs, perform this operation to clear the unit. Procedure: 1. While pressing two buttons of [TUNER] and [MD/TAPE] simultaneously, press the 1/u button to turn the power ON. 2. The message INITIAL appears and initialization is performed. Fluorescent Indicator Tube Test Mode All fluorescent segments are tested. When this test is activated, all segments turn on at the same time, then each segment turns on one after another. Procedure: 1. While pressing two buttons of [TV/SAT] (US , Canadian and Australian models)* and [DIRECT] simultaneously, press the 1/u button to turn the power ON. 2. All segments turn on at the same time, then each segment and LED turns on one after another. 3. The message FINISH appears when this test is complete. *) Except US, Canadian and Australian models are [TV/LD] AUTO-BETICAL Check Mode (AEP model) To auto-scanning and memories of RDS station. Procedure: 1. While pressing the [MEMORY] button, press the 1/u button to turn the power ON. 2. The message AUTO BET appears and each function is selected one after another. AM Tuning Interval Selection Mode (US, Canadian and E models) Either 9 kHz step or 10 kHz step can be selected for the AM tuning interval. Procedure: 1. Set the FUNCTION to AM. 2. Press the 1/u button to turn the power OFF. 3. While pressing the [TUNING+] or [PRESET+]button, press the 1/u button to turn the power ON. 4. Either the message 10 k STEP or 10k STEP appears. 5. Select the desired step. Software Version Display Mode The software version is displayed. Procedure: 1. While pressing two the buttons of [MD/TAPE] and [DIRECT] simultaneously, press the 1/u button to turn the power ON. 2. The software version is displayed. SOUND FIELD Setting Clear Mode All SOUND FIELD setting are cleared. Procedure: 1. While pressing the [SOUNDFIELDON/OFF] button, press the 1/u button to turn the power ON. 2.
