Preparation
Items to Have Ready• USB memory device that has a capacity less than or equal to16 GB

The PCR-LE2 Series cannot detect a USB memory device whose
capacity is larger than 16 GB. Refer to the PCR-LE2 Series
manual, and whenever possible, use a USB memory device whose
operation has already been confirmed (see the listed manufacturer
name, model number, and capacity information in the PCR-LE2
Series manual).

• Update file (PCRLE2.bin)
Download the update file from the Kikusui Electronics Corporationwebsite.

Use the Windows XP or later operating system. You cannot use anyother operating systems.

If you update a PCR6000LE2 or PCR9000LE2 whose firmware
version is 4.00, the DC output in three-phase AC+DC mode will
not meet the specifications.
