resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

4. �com update
The system �com and DSP can be updated from a disc.
The �com should be updated to the latest version, when GU-3689(MAIN PWB UNIT) or IC102(Flash ROM) is replaced.
(1) Creating the update disc
Use the procedure described below to create the disc for updating the system microprocessor and DSP.
Store the update file on a CD-R or CD-RW disc in ISO9660 Mode 1 format, then finalize the disc.
Write the distributed update files using the "DISC AT ONCE" CD writing software and finalize.
Do not record any other software or data on the disc containing the update software.
Do not change the file names - use the file names as distributed.

(2) Updating the system �com and DSP
Turn on the power and load the disc created in (1) above.
When the update disc is detected, "Version Up" is displayed. And "xxxx yyyyy" and "Push Play!" are displayed by turns.
xxxx : Old Version No., yyyy : New Version No.
Press the PLAY/PAUSE button. "NowLoading" is displayed and the updating procedure starts.
As updating proceeds, the playback position indicator lights in order from left to right.
NOTE: In some extremely rare cases, the updating procedure is not completed. If the updating procedure has not finished after
three minutes, there could be a problem. Turn off the power and repeat the operation from step (2) .
Depending on the problem that occurred, it may happen that no other operations can be performed. If this happens, GU-
3689 IC102 must be replaced. Software must be pre-recorded on the IC102. (When ordering the IC102, order the more
recent system microprocessor version number (GEN number).)
When updating is completed, "Complete!" is displayed and the disc is ejected.

ADJUSTMENT
When the motor (FG-3500) is replaced, platter rotation speed adjustment is necessary.
(1) Start the Platter Rotation Speed Fine Adjust mode in the test mode. (Refer to page 9)
The actual revolution number is indicated on the lower part of the Character display. (Standard is 33rpm)
The difference from the standard revolution number is indicated on the upper part of the Character display.
(2) Turn the parameter knob. And the "D_**"(left side) of the lower part of the Character display is set to "D_77".
Then check the difference from the standard revolution number.
a) The difference from the standard number is -5% ~ +1% :
Turn the parameter knob to set "-2%". And push the parameter knob to complete the adjustment.
b) The difference from the standard number is outside of -5% ~ +1% :
Start the platter revolution check mode in the test mode. (Refer to page 9)
Present revolution number is indicated on the lower part of character display. (Standard is 33rpm)
Difference from the standard revolution number is indicated on the upper part of character display.
Make adjustment by turning VR701 on the power unit GU-3690 so that difference from the standard revolution number
indicated on the upper part of character display becomes -2%.
