SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
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.
LASER RADIATION
Do not stare into beam or view directly with optical instruments, class 3A laser product.

µCOM UPDATE
With the DN-D4500 and BU4500, the system µcom and DSP can be updated from a disc.
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 µcom and DSP
(1) 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.
(2) 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. (1).
Depending on the problem that occurred, it may happen that no other operations can be performed.
If this happens, 00D GU-3674 : IC302 must be replaced. Software must be pre-recorded on the IC302.
(When ordering the IC302, order the more recent system microprocessor version number (00D GEN 6951).)
(3) When updating is completed, "Complete!" is displayed and the disc holder is opened.
