- USB Power: Connect the provided USB power cord to the DC5V port on the back of the clock and plug the other end into a USB power adapter (not included) or a powered USB port.
- Battery Power (Backup): Open the battery compartment on the back of the clock. Insert 4 x AAA batteries (not included), ensuring correct polarity (+/-). Note: Batteries are primarily for backup and may not provide continuous display.
- Memory Battery: The clock also uses a CR2032 button cell battery (usually pre-installed) for "power off memory," which retains time settings even when the main power is disconnected.

Maintenance
- Cleaning: Wipe the clock surface with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the wooden finish or electronic components.
- Battery Replacement: If using AAA batteries for backup, replace them when the display becomes dim or inconsistent, or if the clock fails to retain time during power outages. Ensure correct polarity.
- CR2032 Battery: The CR2032 battery for memory retention typically lasts for several years. If the clock loses time settings after a power disconnection, the CR2032 battery may need replacement.
- Environment: Keep the clock away from direct sunlight, extreme temperatures, high humidity, and strong magnetic fields to prevent damage.
