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 VERSION UPGRADE

System µcom can be upgraded in the following manner.

Version Upgrade Method

1.Record the version upgrade software on a CD-R or CD-RW disc, only as one file with the format ISO9660 Mode-1.

The file name of the supplied version upgrade software should be used as is and this disc needs to finalize.

2.Hold the disc by the edges and place it on the disc tray. 3.Press the OPEN/CLOSE button to start the version upgrade.

"Version Up"→"Push Play!" "xxxx->XXXX" are displayed. xxxx : current version XXXX : upgrade version

4.Press the PLAY/PAUSE button.

"Now Writing" → "Writing-XXX" are displayed.

XXX : count up from 000 to161 5.When the version upgrade is finished, "Complete!" is indicated. 6.Turn off the power once and turn on again.

Press the OPEN/CLOSE button and remove the disc.

NOTE: When the power is turned off before "Complete!" is displayed, µcom version is not written correctly.
