CLOCK
The CLOCK display shows the current day, time, and
date. Pressing the CLOCK key will show the current
day, time, and date.
It is important that the date and time be correct, otherwise the
daily schedule will not function as desired if programmed.
In addition, for ease of troubleshooting via the History print-
outs, the day, time, and date should be correct.
To change the day, time, and date press the CLOCK
key. The display will show something similar to the
following:

2 5 j A N 0 2
The line under the F is the cursor. If the day is correct,
press the ENTER/ADV key. The cursor will move under
the 0 in 08 hours. If the day is incorrect, press the UP
or DOWN
arrow keys until the desired day is displayed
and then press the ENTER/ADV key at which time the
day will be accepted and the cursor will move under
the first digit of the “2 digit hour”. In a similar manner,
the hour, minute, meridian, month, day, and year may
be programmed, whenever the cursor is under the first
letter/numeral of the item. Press the UP or DOWN ar-
row keys until the desired hour, minute, meridian, day,
