Setup Guide
Follow these steps to set up your MASHI Digital Wall Clock:
- Install Backup Batteries (Optional but Recommended): Open the battery compartment on the back of the clock. Insert 2 AAA batteries (not included). These batteries serve as a memory function to retain time settings during power outages and do not power the clock for normal operation.

- Initial Time Setting: The clock should power on automatically. Use the remote control to set the correct time, date, and other preferences. Refer to the "Operating Instructions" section for detailed steps on setting time and other features.

Troubleshooting
