Caution when programming
Writing should be done at the defined voltage and timing. In case of EPROM mode, programming
voltage is 12.5V. More than defined voltage can give device so great damage to destroy it.
Before writing you had better ascertain the characteristics of socket and socket adapter of EPROM
writer. It can happen to write error when you touch socket adapter or device. We recommend below
flow to improve reliability after writing.
