5.7 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 pressed,
the display will go back on. It will stay on until the next OFF time is
reached.
5.7.1
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. Then release the mode
button. The clock will now be in the set OFF/ON times. This is
indicated by the current OFF time (initially zero hours, zero minutes),
and the leftmost colon will be on. Seconds digits will be blank.
