Chapter 6. MAINTENANCE AND INSPECTION
CAUTION
Do not throw used batteries into fire or discard. If you discard them at your
site, follow regulations and rules stipulated by your local self-governing body.
Do not short-circuit the batteries as they may over heart or catch fire, also do
not expose them to water.
When replacing the battery, please note the followings:
• Clock data, user touch switch adjustment data and user contrast
adjustment data will be initialized during battery replacement. In this case,
please reconfigure the settings.
• The trend data will be lost during battery replacement.
• The changes that have been made to the recipe data using the EST will be
lost during battery replacement.
In case of the EST’s system program of F/W (firmware) version R0021 or
later, the changes are automatically written to the EST’s memory during the
application upload function of the AP Editor. In case of the F/W version
R0020 and earlier, the changes are written into the memory by using the
“Recipe data write” switch in the system menu.
