5.5 Setting the Alarm Time
Set the alarm time by pressing the black function button on the left side
momentarily. When pressed, the right most colon will be flashing, and the
hours digits will flash on and off once a second.
5.5.1
Enabling the Alarm
The alarm function is enabled by putting the Alarm Enable Switch (SW3) in
the ON position.
When this switch is OFF, the alarm time will be ignored. Also, if an alarm is
present, turning the switch OFF will cancel the alarm.
When the time equals the alarm time, the alarm output will go on for 30
seconds, unless canceled by the Alarm Enable Switch.
5.5.2
Set Alarm time mode
When the clock is in the set time mode, the current alarm time will be
displayed with the hours (2 leftmost digits) blinking and the right
most colon will be flashing.
To cancel setting the alarm time value at any point, press and hold the
red mode button until the display goes blank. This will cancel setting
the alarm time. When the mode button is released, the clock will go
back to the normal display. The old alarm time value will be used.
