Sharp Atomic Clock SPC373: The Ultimate User Guide and Troubleshooting Manual
The Sharp Atomic Clock SPC373 is a popular choice for those who value precision and a sleek design. Because it synchronizes with the National Institute of Standards and Technology (NIST) radio signal in Fort Collins, Colorado, it is technically one of the most accurate timekeepers you can own.
However, losing the physical manual is common. This guide serves as your comprehensive digital user manual to help you set up, customize, and troubleshoot your SPC373. 1. Initial Setup: Getting Started
Before you begin, place the clock near a window facing Colorado for the best signal reception during the initial sync.
Insert Batteries: Open the battery compartment on the back and insert 2 AA alkaline batteries (not included).
The Search Begins: Once the batteries are in, the clock will automatically begin searching for the Atomic Signal (RCC). You will see the "Tower" icon flashing.
Wait for Sync: It can take anywhere from 2 to 24 hours for the clock to find the signal. It is best to let it sit overnight, as radio interference is lowest in the dark. 2. Manual Time and Date Settings
If you live in an area with poor reception or don’t want to wait for the atomic sync, you can set the clock manually. Table of Contents
Enter Set Mode: Press and hold the SET button for 2 seconds.
Adjust Values: Use the UP or DOWN buttons to change the flashing digits.
Confirm and Move On: Press the SET button again to cycle through the following sequence: Month/Date Format 12/24 Hour Format
Finish: Once you’ve set the minutes, press SET one last time to return to the main display. 3. Selecting Your Time Zone
The clock won't show the correct time if the Time Zone isn't selected, even if it syncs with the atomic signal.
Press the TIME ZONE button (often labeled with specific zones like PST, MST, CST, EST).
Keep pressing until the correct indicator appears on the screen.
Daylight Savings (DST): The SPC373 features an Auto DST function. Ensure the DST switch on the back is set to "ON" if you want the clock to adjust itself twice a year. 4. Setting the Alarm
Access Alarm Mode: Press the ALARM button once to view the alarm time.
Set Time: While the alarm time is showing, hold the ALARM button until the hours flash. Use UP/DOWN to adjust, then press ALARM to switch to minutes.
Activate: Use the ALARM ON/OFF switch or button to ensure the alarm icon (usually a small bell) appears on the display.
Snooze: When the alarm sounds, press the SNOOZE/LIGHT button on top for a 5-minute delay. 5. Troubleshooting Common Issues The "Tower" Icon is Gone
This means the clock failed to receive the signal last night. This can happen due to weather or electronic interference. Try moving the clock away from computers, TVs, or microwaves. The Time is Exactly One Hour Off
This is almost always a Time Zone or DST setting issue. Toggle through the time zones until the hour aligns with your local time. The Display is Faint
Atomic clocks require a consistent voltage to maintain the radio receiver. If the screen is dimming or the clock keeps resetting, replace the batteries with fresh brand-name alkaline batteries. Avoid rechargeable batteries as they typically have a lower voltage (1.2V vs 1.5V). 6. Maintenance Tips
Location: For best results, keep the clock away from large metal surfaces which can block radio waves.
Cleaning: Use a soft, dry cloth. Avoid harsh chemicals or water, as the unit is not waterproof.
By following these steps, your Sharp SPC373 should provide years of maintenance-free, split-second accuracy.

The Last Manual
Arthur’s fingers trembled as he unfolded the worn trifold paper. It wasn’t just any paper. It was the Sharp SPC373 Atomic Clock User Manual, and it was the last one on Earth.
The clock itself—a bland, grey plastic rectangle—sat on his dust-covered coffee table, its LCD screen blank. For three years, since the Great Signal Collapse, no one had cared about atomic time. Without the WWVB radio signal from Fort Collins, the “atomic” feature was a lie. People threw their “smart” clocks into landfills. They’d gone back to sundials and wristwatches.
But Arthur was a restorer. He was also desperately lonely.
He squinted at Section 4: Manual Setting (When Atomic Signal is Unavailable).
“Step 1: Press and hold the ‘SET’ button for 3 seconds,” he read aloud, his voice cracking from disuse.
He pressed. The seconds display began to blink. Hope, a tiny green shoot, broke through the concrete of his despair.
He followed the manual like a sacred text. Step 4: Use the ‘UP’ button to set the year. He set it to 2026, though everyone else called it “Year 4 of the Drift.” Step 7: Set the DST to ‘OFF’ permanently.
It took him an hour to fumble through the time, the date, the 12/24-hour format. The manual’s diagrams were cryptic—little icons of suns and moons that seemed to mock him. But on page two, a footnote saved him: Note: When the battery is low, the display will show a flashing ‘BAT’ icon.
He replaced the AA batteries. Suddenly, the second hand (a phantom on the digital readout) began to tick.
He held the clock to his ear. Tick. Tick. Tick. adjust with UP/DOWN
It was the only metronome in a silent world. He placed it back on the table, and for the first time in years, he knew what time it was: 4:17 PM.
He wasn't just measuring hours. He was measuring his survival.
Then, a miracle. At precisely 2:00 AM, as promised on page 3, the clock attempted a signal sync. The antenna icon flickered. Arthur held his breath. The world’s atomic clocks had long been silent… or so he thought.
The icon stopped flickering. The clock displayed 12:00 AM—the signal was dead.
But the manual had a final instruction, hidden in the safety warnings: Do not expose to extreme temperatures, direct sunlight, or despair.
Arthur smiled. He didn't need Fort Collins. He had the manual. He had the buttons. He had the small, stubborn power of setting time himself.
He set the clock to 6:00 AM—a new beginning. Then he stepped outside, the Sharp SPC373 tucked under his arm, to teach his neighbors how to wind their broken watches again.
Maintenance and care
- Replace batteries once per year or when low-battery indicator appears.
- Clean case and display with a soft, dry cloth; avoid solvents and water ingress.
- Keep away from extreme temperatures, humidity, and direct sunlight to protect electronics and display.
Final Verdict & Tips for Success
The Sharp Atomic Clock SPC373 is a "set it and forget it" device—once it locks onto the signal. Your success hinges on the first 24 hours.
Pro Tip: On the first night, place the clock directly next to a west-facing window (toward Colorado) and turn off all Wi-Fi routers and phone chargers within 6 feet. By morning, the tower icon should be solid and your time will be perfect to the second.
