Setting the time on your Sharp SPC569 Atomic Digital Alarm Clock is straightforward. Here's a step-by-step guide:
- Plug in the Clock: First, connect the AC adapter to a 120V AC ~ 60Hz power outlet.
- Set Your Time Zone: The display will show flashing TIME ZONE digits. Use the + or - buttons to choose your time zone (HAWAII, ALASKA, PACIFIC, MOUNTAIN, CENTRAL, EASTERN). Press the TIME ZONE button to confirm your selection. The default time zone is EASTERN.
- Enter the Year: The YEAR digits will flash. Use the + or - buttons to set the correct year. Then, press the CALENDAR button to confirm.
- Set the Month: The month digits will flash. Use the + or - buttons to select the correct month and press the CALENDAR button to confirm.
- Enter the Date: The date digits will flash. Use the + or - buttons to set the correct date and press the CALENDAR button again to save and exit the calendar settings.
- Initiate Atomic Signal Search: Press and hold the WAVE button for 3 seconds. The clock will begin searching for the WWVB signal, which can take 2-10 minutes per attempt. If the signal isn't found, the hour digits will flash, allowing for manual time setting.
- Manual Time Setting (if needed): If the atomic signal isn't found, use the + or - buttons to set the correct hour and then press the TIME button to confirm. The minute digits will then flash, allowing you to set the correct minutes with the + or - buttons. Press the TIME button again to save and exit the manual time setting.
- Automatic Updates: Once the Atomic signal is found, the clock will automatically update. This process may take between 24 and 48 hours to complete.
