SECTION 3 TEST MODE HCD-SH2000 PANEL TEST MODE This mode is used to check the fluorescent indicator tube, LEDs, keys, [MASTER VOLUME] jog, model, destination and software version. Procedure: 1. Press [SEARCH] button and [OPTIONS] button simultane- ously and hold 3 seconds. 2. All LEDs and segments in fluorescent indicator tube will light up. 3. When you want to enter to the software version display mode, press [FLANGER] button. The model information appears on the fluorescent indicator tube. Press [FLANGER] button again to view the destination information. 4. During the destination information display, press [FLANGER] button. Each time [FLANGER] button is pressed, the fluorescent indicator tube shows the version of each category software in the following sequence: SC, MTK (DMB Board firmware version), UI, PF, SYS, CD, CDMA, CDMB, ST, TA, TAS, TM and return back to model information display. 5. When [SEARCH] button is pressed while the version numbers are being displayed except model and destination, the date of the software creation appears. When [SEARCH] button is pressed again, the display returns to the software version display. 6. Press [ISOLATOR] button, the key check mode is activated. 7. In the key check mode, the fluorescent indicator tube displays "K 0 V0". Each time a button is pressed, "K" value increases. However, once a button has been pressed, it is no longer taken into account. "V" value increases in the manner of 0, 1, 2, 3 ... if [MASTER VOLUME] knob is turned clockwise, or it decreases in the manner of 0, 9, 8, 7 ... if [MASTER VOLUME] knob is turned counterclockwise. 8. When [SOUND FLASH] button is pressed after all LEDs and segments in fluorescent indicator tube light up, alternate segments in fluorescent indicator tube and LEDs would light up. If you press [SOUND FLASH] button again, another half of alternate segments in fluorescent indicator tube and LEDs would light up. Pressing [SOUND FLASH] button again would cause all segments in fluorescent indicator tube and LEDs light OFF. Pressing [SOUND FLASH] button again would cause all segments in fluorescent indicator tube and all LEDs light up. 9. To release from this mode, press the [SEARCH] button and [OPTIONS] button in the same manner as step 1, or disconnect the power cord.

This mode is not available for Saudi Arabian, European and Russian models. Procedure: 1. Press @/1 button to turn on the system. 2. Press [FUNCTION] button repeatedly to select the "AM". 3. Press @/1 button to turn off the system. 4. Press [ENTER] button and @/1 button simultaneously. The system turns on automatically. The message "AM 9K STEP" or "AM 10K STEP" appears on the fluorescent indicator tube and thus the channel step is changed. CD SHIP MODE (WITH MEMORY CLEAR) This mode moves the optical pick-up to the position durable to vibration and clears all data including preset data stored in the data flash to initial conditions during the next AC-In. Use this mode when returning the set to the customer after repair. Procedure: 1. Press @/1 button to turn on the system. 2. Select CD function and without dics inserted. 3. Press [EJECT] button and @/1 button simultaneously for 3 seconds. The system turns off automatically. 4. A message "MECHA LOCK" is displayed on the fluorescent indicator tube and the CD ship mode is set. CD SHIP MODE (WITHOUT MEMORY CLEAR) This mode moves the optical pick-up to the position durable to vibration. Use this mode when returning the set to the customer after repair. Procedure: 5. Press @/1 button to turn on the system. 6. Select CD function and without dics inserted. 7. Press [CD] button and @/1 button simultaneously. The system turns off automatically. 8.
