End of
battery life
The recommendation time of battery
replacement has come. Since it is
necessary to replace the battery,
contact an agent from which you
purchased the UPS, or a maintenance
company. Although the alarm
(indication and warning beep) can be
stopped by pressing the RESET
switch for 3 seconds, the alarm
(warning beep) is issued again 24
hours later or at the restart. When
only the warning beep is stopped by
pressing the RESET switch 1 second
or more, the alarm (warning beep) of
the end of battery life will be issued
again at the automatic battery check
which is performed every two weeks.
