① The battery remainder time
This piece of battery information indicates the battery module's remaining life time (see the
asterisked (*) note on the next page). Where the battery module is not connected to the
CMU module, the text "Battery unconnection" is displayed in place of the remaining life.
If you want to replace the battery module, follow the procedure described under "6.3
Replacing the Battery Module."
If you want to replace the CMU module, follow the procedure described under "6.4
Replacing the CMU Module."
② The battery remainder time indicator bar graph
This bar graph shows the battery module' remaining life time in percent (%) of the maximum
possible life time. This piece of battery information is not displayed where the battery
module is not connected to the CMU module.
③ The last battery exchange date
This piece of battery information indicates the date and time the battery module was replaced
last time. It is read from the CMU module and displayed on screen.
The time of pushing the CMU module's BATT.SET switch is recorded in the CMU module's
internal memory. If no such information is recorded in the CMU module, the text "The
exchange date is not set" is displayed instead.
If the CMU module is replaced before the battery module is replaced, enter the date and time
of the replacement and click the Change button to correct the current date and time.
