This test performs a failure diagnosis on the unit and performs a test to check for battery deterioration.
Use the procedure below to check whether a circuit failure has occurred inside the unit and whether
battery replacement is required.
This test is performed if the “Power” switch is ON or performed automatically (You do not have to per-
form any special operations). The test is performed once every 4 weeks after the AC input is connect-
ed to commercial power and power distribution begins. The test is not performed if the “Power” switch
is OFF.
If the battery is not fully charged, the self-diagnostic test is not executed immediately.
After charging is complete, it is automatically executed.
(1) When the self-diagnostic test is executed, the Battery Mode starts automatically (No beep sounds).
After the test is complete, the normal operation automatically starts.

When the beep is sounding, you can suspend it by pressing
and holding the ESC switch for 0.5 seconds or longer.
