Setting the display ON/OFF times
The clock display can be programmed to turn off and on at a specified
time. Turning the digits off at night can extend the life of the tubes, or it
may be desired to have the clock dark at night. The OFF time setting is
the hours: minute when the display will turn off. The ON time setting is
the hours: minute when the display will turn back on. Note: When the
display is off, and either the red mode button or the black function button
is momentarily pressed, the display will go back on for 1
½
minutes.
If auto ON/OFF option (‘9’, ‘19’, ‘29’ for display brightness option) is
selected, the display will be ON during the ON time, regardless of
ambient light level. During the OFF time, auto display ON/OFF will
control the display. See Section ‘Option 5 – Brightness level’. If OFF/ON
time is disabled (ON and OFF time set to the same time), Auto ON/OFF
will be enabled all the time.
OFF/ON mode is disabled if the hour setting for both OFF and ON are
set to the same value. Example: OFF time = 12:01, ON time = 12:45,
OFF/ON mode disabled.
Note: Default setting is display OFF at 23:00, and display ON at 6:00.

Entering the OFF/ON set time enable
Enter the OFF/ON set time enable by pressing and holding the red
mode button until the display goes blank. When the display is
blank, release the mode button. At this point the display will show
blinking hour digits and the minutes digits for the OFF time. The
clock will now be in the Set OFF/ON times mode, which is
indicated by the current OFF time (initially zero hours, zero
minutes), and the leftmost colon on. Seconds digits will be blank.
