3.25.3 Press the up- or down-arrow key to scroll between the choices. When the display shows
the desired choice press "FUNC/ENTR" to enter your choice.
3.25.4 The display and all other time outputs indicate UTC without any DST adjustment if a
time-zone offset of 00:00 is selected. Regardless of the time-zone offset there will be no
DST adjustment if "Off" is selected for the DST function. Some local jurisdictions enter
and leave DST at times other than those set by U.S. federal law. Therefore, TrueTime
has included a "Manual" choice which allows the user to override the times of entry into
and exit from DST by selecting his own. If "Manual" is selected for the DST function, the
display will show:
Enter dst: 02:00
1st Sun in Apr
or some other entry time and date. Press the right- or left-arrow keys to position the
cursor beneath the character that you wish to change. Press the up- or down-arrow keys
to scroll through the possible choices. Alternatively, directly enter the numbers using the
keypad. The cursor will automatically advance to the next position. The hours may
range from 0 to 23. The week may be "1st", "2nd", "3rd", "4th", or "Last". Any day of the
week or month may be selected. The above display means that Daylight Savings Time
will start at 2 a.m. local time on the first Sunday in April each year. DST transitions may
be set to occur at any hour of the day, any day of the week or any month of the year with
the following restriction: If either transition is less than 24 hours from the start or end of a
year, the transition may not occur at the desired time.
