GENERAL
This menu item is used to tell the 5601MSC how many power supplies are
installed in the chassis. This menu item must be set correctly when first
installing the 5601MSC and when adding or removing a power supply from
the chassis, otherwise power supply monitoring will not work properly.
Select
One Power Suppl

power supply with the other module being a 5601FM fan module.
Select
Dual Pwr Supply

GENERAL
This menu item can be used to reset the GPS receiver connected to the

stuck in a bad state. It can also be used to confirm that the GPS receiver is
programmed with the correct settings as provided by the Evertz factory.

4.5.10. Setting the Daylight Saving Time Rules
Daylight Saving Time (DST) or Summer Time, as it is called in many countries, is a way of getting more
daylight out of the summer days by advancing the clocks by one hour during the summer. Then, the
sun will appear to rise one hour later in the morning when people are usually asleep anyway, at the
benefit of one hour longer evenings when awake. The sunset and sunrise are one hour later than
during normal time.
To make DST work, the clocks have to be adjusted one hour ahead when DST begins, and adjusted
back one hour to standard time when DST ends. There are many countries that observe DST, and
many who do not.
During the months of March/April to September/October, the countries in the Northern Hemisphere are
having their summer and may observe DST, while the countries in the Southern Hemisphere are having
winter. During the rest of the year (September/October to March/April) the countries in the Southern
Hemisphere are having their summer and may observe DST, while the countries in the Northern
Hemisphere are having winter.
Daylight Saving Time is difficult to predict, as many countries change the transition days/principles
every year because of special happenings or conditions that have happened or will happen.
