The clock features a large LED display on the front. Controls are located on the top, sides, and back of the unit.
Setup
- Power Connection: Connect the provided USB charging cable to the clock's power input port. Plug the other end into a standard USB power adapter (not included) or a powered USB port. The clock requires continuous power to operate.
- Memory Function: The clock has a built-in memory function. In case of a power outage, it will retain your time and alarm settings. You will not need to reset them once power is restored. Note that the internal battery only supports memory function and cannot power the clock for normal operation.
Operating Instructions
1. Time Display (12/24 Hour Format)
- In normal time display mode, press the 'SET' button to switch between 12-hour and 24-hour formats.
2. Setting Alarms
- The clock supports two independent alarm settings. Refer to the specific buttons on the back or side of the clock for 'Alarm 1' and 'Alarm 2' settings.
- Once an alarm is set, the corresponding alarm symbol will illuminate on the display.
3. Snooze Function
- When an alarm sounds, gently tap the top of the alarm clock to activate the snooze mode. This will provide an additional 5 minutes of sleep.
