Setup
1. Unpacking
Carefully remove all components from the packaging. Ensure you have the projection alarm clock, a USB cable, and this English manual.

3. Battery Installation (Backup)
The clock includes a built-in 2032 button battery. This battery serves as a backup to retain time and settings during a power outage, preventing the need for re-setting after power is restored. No user installation is typically required for this backup battery.
4. Initial Time Setting
Upon initial power-up, the clock may display a default time. Refer to the 'Operating' section for detailed instructions on how to set the correct time and date.
Operating Instructions
1. Time and Display Settings
Locate the 'SET' button on the top or back of the clock. Press and hold 'SET' to enter time setting mode. Use the '+' and '-' buttons (often labeled 'VOL' and 'AL' or similar) to adjust hours, minutes, and other settings. Press 'SET' again to confirm each step and move to the next setting.
2. Display Brightness Adjustment
The large LED screen brightness can be adjusted manually or automatically. There are typically four manual brightness levels: off, slightly bright, medium, and bright. To adjust manually, press the dedicated brightness button (often labeled with a sun icon or 'DIMMER'). The clock also features an automatic light detection function. When activated, the display brightness will adjust automatically based on the ambient light conditions in the room.

3. Alarm Setting
The alarm mode allows you to set a traditional beep alarm or use the FM radio as your alarm sound. To set an alarm:
- Press the 'AL' (Alarm) button to enter alarm setting mode.
- Use the '+' and '-' buttons to set the desired alarm time.
- Press 'AL' again to confirm the time.
- Select the alarm sound: traditional beep or FM radio. Use the '+' or '-' buttons to toggle between options.
- Press 'AL' one more time to activate the alarm. An alarm icon will appear on the display.
4. FM Radio Operation
To turn on the FM radio, press the 'RADIO' button. Use the 'VOL' (Volume) buttons to adjust the sound level. To scan for stations, press and hold the 'RADIO' button or a dedicated 'SCAN' button. The radio can be set to automatically turn off after a specified period (5 to 90 minutes). Refer to the manual for specific button functions for setting the auto-off timer.
5. Projection Feature
The clock features a high-definition projection that can display the time onto a wall or ceiling. The projection lens can rotate 180 degrees, allowing you to adjust the projection angle. The effective projection distance is up to 5 meters. To activate or deactivate the projection, press the dedicated 'PROJECTION' button (often located near the lens).
Maintenance
1. Cleaning
To clean the clock, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the finish or internal components. Ensure the device is unplugged before cleaning.
2. Battery Replacement
The built-in 2032 button battery is primarily for backup purposes. If the clock consistently loses time or settings after a power outage, the backup battery may need replacement. This procedure typically requires opening the device and should ideally be performed by a qualified technician to avoid damage.
