CONTENT
When the weekly timer is operated at the default value of the OFF time, the power supply
may cut itself off after it has been left for five minutes. This error has been caused due to
setting of 0:00 as the default value of the OFF time. As a countermeasure, the default value
of the OFF time has been changed to 24:00 from November at the factory.

Be sure to check that the setting of the days of the week for which the power supply should
be switched ON is not set at ON: 0:00/OFF: 0:00 in the weekly timer. If the weekly timer is
used in this setting, the power supply for that the same day may be cut off after it has been
left for five minutes.
