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.

Note
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.
