2. Activating/Deactivating the Alarm

Slide the switch to "ALARM ON" to activate the alarm. An alarm indicator (e.g., a bell icon or "ON") will appear on the display.
Slide the switch to "ALARM OFF" to deactivate the alarm. The alarm indicator will disappear.

3. Using the Snooze/Light Function

The large button on the top of the clock serves two primary functions:

Snooze: When the alarm sounds, press the top button to temporarily stop the alarm. The alarm will sound again after a few minutes (typically 5-10 minutes, depending on the model). The "SNZ" indicator will flash on the display.
Light: Press the top button at any time to illuminate the display for a few seconds, allowing you to read the time in low-light conditions.

Your clock may allow you to switch between 12-hour (with AM/PM indicator) and 24-hour (military time) formats.

While in "TIME SET" mode, repeatedly press the HR button. The display will cycle through 12-hour and 24-hour formats. Stop when your preferred format is shown.
Alternatively, some models have a dedicated switch for this function, usually labeled "12/24H" or similar.
