6. Operating Instructions
6.1. Display Modes
The clock has two main display modes:

- DP-2: Displays Time continuously.
To switch between DP-1 and DP-2, press the SET button briefly.
6.2. Setting Time and Date
To enter the setting mode, press and hold the SET button for 3 seconds. The display will show the first setting item (YEAR) flashing.
- While an item is flashing, use the UP or DOWN buttons to adjust the value.
- Press the SET button briefly to move to the next setting item.
- The setting sequence is: YEAR → MONTH → DATE → 12/24H Format → HOUR → MINUTE → ALARM 1 (AL1) → ALARM 2 (AL2) → ALARM 3 (AL3).
- After setting the last item (AL3), the clock will exit the setting mode automatically.
6.3. Setting Alarms
The clock supports three independent alarms (AL1, AL2, AL3). Each alarm sounds for 1 minute.
- Enter the setting mode by pressing and holding the SET button for 3 seconds.
- Press SET repeatedly until you reach the AL1, AL2, or AL3 setting.
- When the alarm hour or minute is flashing, use the UP or DOWN buttons to set the desired alarm time.
- Press SET to confirm and move to the next alarm setting or exit.
6.4. Adjusting Brightness
The clock offers three levels of brightness (L1, L2, L3), with L3 being the brightest and L1 the dimmest. Additionally, the display automatically reduces brightness by half between 18:00 (6 PM) and 07:00 (7 AM).
- Press and hold the UP button for 3 seconds to enter brightness adjustment mode. The current brightness level (e.g., "L3") will be displayed.
- Use the UP or DOWN buttons to cycle through the brightness levels (L1, L2, L3).
- Once the desired brightness is set, press and hold the UP button for 3 seconds again to exit brightness adjustment mode.
6.5. Activating Sound Control Mode
Sound control mode (power-saving mode) is recommended when the clock is powered by batteries. In this mode, the display turns off and activates when a sound is detected (e.g., a clap or tap).
To toggle sound control mode:
- Press the DOWN button briefly.
- "ON:SD" indicates sound control is active.
- "--:SD" indicates sound control is off, and the display will remain continuously on (if in DP-2 mode).
