Initial Power-On
Upon inserting batteries, the clock should power on automatically. The display will show default time, date, and temperature settings. You may need to adjust these to your local time and preferences.

- Press SET again to move to the next setting (e.g., hours to minutes, month to day).
- Once all settings are adjusted, press MODE to exit the setting mode.
12/24 Hour Format Selection
In time setting mode, when adjusting the hour, you can toggle between 12-hour (with AM/PM indicator) and 24-hour formats using the UP or DOWN buttons.

LED Color Change
The pyramid alarm clock features a colorful LED backlight with 7 different colors. The backlight can change colors automatically or be set to a specific color.


To activate or change the LED backlight, typically a short press of the 'UP' button or a dedicated light button (if present) will cycle through colors or activate the color-changing mode. Refer to the product's specific button functions for precise control.
Maintenance
Cleaning
- Wipe the clock with a soft, dry cloth.
- Do not use abrasive cleaners or solvents, as they may damage the surface.
Battery Replacement
- When the display dims or functions become erratic, it's time to replace the batteries.
- Follow the battery installation steps in the Setup section.
- Dispose of used batteries responsibly according to local regulations.
Troubleshooting
- Clock not turning on or display is dim:
- Ensure batteries are correctly installed with proper polarity. Replace with fresh AAA batteries.
- Alarm not sounding:
- Verify that the alarm time is set correctly and the alarm function is activated. Check battery level.
- LED light not changing colors or staying on:
- The LED backlight is designed to change colors. If you wish for the light to stay on continuously, this model may not support that specific function, as its primary design is for dynamic color changes or as a temporary night light. Check battery level as low power can affect light intensity.
- Incorrect temperature reading:
- Ensure the clock is not placed in direct sunlight or near heat sources, which can affect the sensor. Verify the correct temperature unit (Celsius/Fahrenheit) is selected.
