Setup
1. Power Connection
Connect the provided 9.8-foot power cable to the clock and then plug the 5V/2A power adapter into a standard wall outlet. The clock requires continuous power to operate.

- Wall Mounting: Use the integrated hang holes on the back of the clock. A measuring rod, hook wall stickers, and wall screws are provided to assist with installation. Mark the desired position on the wall, drill pilot holes if necessary, and secure the clock using the appropriate hardware.
Operating Instructions
The clock can be operated using the buttons on the device or the included remote control. For most functions, the remote control offers greater convenience.

1. Time Setting
Use the remote control to access time setting mode. Follow the on-screen prompts to adjust hours, minutes, and 12/24-hour format. Confirm settings to save.
2. Alarm Setting
The clock supports two independent alarms. Use the remote to enter alarm setting mode. Set the desired alarm time for Alarm 1 and Alarm 2. You can also select alarm frequency (e.g., Mon-Fri, Mon-Sun). The snooze function can be activated after an alarm sounds.

Cleaning
To clean the clock, gently wipe the display and casing with a soft, dry, or slightly damp cloth. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the surface.
