Battery Back Up for Date and Time
The touchscreen does have an internal battery for
back-up of the date and time settings.
The battery is a CR2032 'coin type' battery and
has an expected service life of 6 years. If the battery
needs to be replaced, there is a battery cover on the
back of the touchscreen display and it can be easily
reached when the panel that the Touchscreen is
mounted to, is pulled forward.
