GC TEST MODE
# This mode is used to check the fluorescent indicator tube, LEDs, keys, JOG, VOLUME jog, model, destination and software version.
Procedure:
1. Press [FORWARD ] (iPod) button, [TUNING MODE] button and [DISC 2] button simultaneously.
2. All segments in fluorescent indicator tube and the LEDs are lighted up.
3. When you want to enter to the model version and destination display mode, press [DISC 1] button. The model information appears on the fluorescent indicator tube.
4. Each time [DISC 1] button is pressed, the display changes to display software version of the software creation. The sequence is MC, GC, SYS, CD, CDDM, CDMA, CDMB, BDA, BDB, ST, TA, TM, and iPod in this order, and returns to the MC version display.
5. When [DISC 3] button is pressed while the software version is being displayed, the date of the software creation appears. When [DISC 3] button is pressed again, the display returns to the software version display. When [DISC 1] button is pressed while the date of the software creation is being displayed, the date of the software creation is displayed in the same order of software version display.
6. Press [DISC 2] button, the key check mode is activated.
7. In the key check mode, the fluorescent indicator tube displays “K 0 J0 V0”.
Turn the [JOG] clockwise; “J” value increases by one. Turn the [JOG] counterclockwise; “J” value decreases by one. Each time a button is pressed, “K” value increases. Press their keys on main unit to check whether the key is detected. 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 [VOLUME] knob is turned clockwise, or it decreases in the manner of 0, 9, 8, 7 ... if [VOLUME] knob is turned counterclockwise.
8. When [EX-CHANGE] button is pressed after all segments in fluorescent indicator tube and the LEDs light up, alternate segments in fluorescent indicator tube would light up. If you press [EX-CHANGE] button again, another half of alternate segments in fluorescent indicator tube would light up. Press [EX-CHANGE] button again would cause all segments lights up.
9. To release from this mode, press three buttons in the same manner as step 1, or disconnect the power cord.

Diagnostic procedure
1. Unplug the AC power cord.
2. Replace R599 on the PNLB Assy with R569.
3. Plug the AC power cord.
4. Turn the unit ON and check each voltage.
Unplug the AC power cord after several seconds, because power will be forcibly supplied even if any voltage is abnormal.
(If abnormal voltage continues, the defective point may produce heat, which may be dangerous.)
5. If the voltage at any power IC is abnormal, the circuit that is connected to the power IC or the power IC itself may be defective.
6. Repair the detective part.
7. Replace R569 on the PNLB Assy with R599 (return R599 to its original position).

Player operation mode command
Play(Trace) / Pause
If it is in a stop state, it will set up and play. Moreover, if it is in a play state, whenever it will push a button, a pause and a play are carried out by turns.
Display a playing address in FL at present.
Note: In this mode, even if it inserts a disc, an automatic setup is not carried out.
Moreover, a play is not carrying out audio reproduction, but is tracing the signal side of a disc.
Trace a disc by a turn of four times speed in the play. The sound is not output.
Track Search F/R
Search a track displayed by a FWD / REV direction and do pause.
Error Rate Count
I measure an error rate from a present position doing a play/pause for about 10 seconds and display a measurement result in FL. Usually, a track to measure is made to search and this button is inputted from a pause state.
For example, it is displayed as "3.56E-4 O.K." etc.
If an error rate is less than 3.00E-3, it will be displayed as OK. If an error rate is larger than 3.00E-3, it will be displayed as NG.
Measurement with the managed disc at the time of factory shipments is a premise.
The product does not judge whether they are inferior goods at the time of service.

be updated to the latest version by using the corresponding update method.
Updating the main microprocessor firmware - Main microprocessor (IC428, DSP P.C.B.), MAIN P.C.B.
Updating the DSP1 FLASH ROM firmware - DSP1 FLASH ROM (IC9, DSP P.C.B.), MAIN P.C.B.
Updating the Wireless Module Firmware and the AirWired microprocessor Firmware - AW-CARD P.C.B.
* The main microprocessor firmware and the DSP1
FLASH ROM firmware also can be updated by using the Firmware CD.
FLASH ROM firmware also can be updated by using the Firmware CD.
Confirmation of firmware version and checksum
Before and after updating the firmware, check the firmware version and checksum by using the selfdiagnostic function menu.
Start up the self-diagnostic function and select “18.ROM VER/SUM” menu.
Using the sub-menu, have the firmware version and checksum displayed, and note down them.
(See “SELF-DIAGNOSTIC FUNCTION”)
* When the firmware version is different from written one after updating, perform the updating procedure again from the beginning.
