  1. To set the time of day:
    1. Push the Run/Set (lower) switch to the right (TIME-SET position).

      2. Note: When the hour setting is for a time between noon and midnight, the small letters PM will appear in the lower left corner of the display; no PM display indicates an AM setting.

    2. Advance the hour setting to the correct number by pushing and releasing the hour button as many times as needed. Or if the button is pressed and held in for longer than 2 seconds, the numbers will continue to advance until the button is released.
    3. Advance the minute setting by repeatedly pushing, or pushing and holding the minute button as needed.
    4. Push the Run/Set switch to the middle (RUN) position.
  2. To set the alarm time:
    1. Push the Run/Set switch to the left (ALARM-SET position).
    2. Set the alarm time by using the same procedure used to set the time of day; remember to set the hour for AM (no letters in the corner of the display), or PM as desired.
    3. Return the Run/Set switch to the middle (RUN) position; the readout will return to the time-of-day setting.
  3. To operate the alarm:
    1. With the alarm time set, push the alarm (upper) switch to the left. An alarm "wave" symbol and the letters AL will appear in the upper left corner of the display when the alarm is on.
    2. When the displayed time of day coincides with the alarm time, the alarm will sound. If the SNOOZ button is not pushed or the alarm switch is not moved, the alarm will automatically stop sounding after 1 minute and will not sound again for 24 hours.
    3. If desired, press the SNOOZ button while the alarm is sounding to shut the alarm off for 3 minutes. The alarm symbol will flash in the display when the button is pushed and will continue to flash until the alarm switch is moved or the alarm has sounded for one minute. The snooze procedure can be done as many times as desired.
    4. Move the alarm switch to the right when you wish to shut off or cancel the alarm; the alarm symbol will disappear.
