This method requires a small Philips head screwdriver. After removing the back panel of the clock, you should see a lithium battery. If the battery is missing, damaged, or the contacts are dirty, you will need to replace it. To do this, remove the old battery and replace it with a new CR2032 battery. Make sure that the positive and negative ends are correctly aligned before reinstalling the back panel of your Atomic Clock.

Some Tips and Suggestions:

1. If you must handle the clock, touch only its back.

2. Keep the clock away from any electronic appliance that may cause interference or harmonic frequencies that affect your clock’s time-keeping capability.

3. To handle the display portion carefully, use a clean, dry cloth with mild pressure to wipe off any grime on its surface.

4. If you are using an AC adapter, make sure it is certified by the manufacturer of your clock.

5. Avoid exposing your clock to direct sunlight or excessive heat.

6. If the time on your atomic clock becomes irregular, it is recommended that you reset it.

Five Common Mistakes to Avoid When Resetting a Sharp Atomic Clock:

1. Resetting Time Zone:

If you still think that the atomic clock adjusts itself to the time zone setting, you will be surprised by your being wrong. Contrary to most people’s belief, this is hardly true with an atomic clock. Atomic clocks know the right time and do not need adjustments for a different time zone. Of course, you can reset the time zone on your clock, but it is unnecessary and will have no impact on the clock’s time-keeping abilities.

2. Resetting Daylight Saving Time:

Similarly, resetting daylight saving time (DST) on your atomic clock is also unnecessary. The clocks automatically adjust themselves for the change in DST. If you are having trouble with your clock after the time change, something else is likely causing the issue.

3. Removing Batteries:

Some people believe that removing the batteries from an atomic clock will reset it. This is not true. Doing this could damage the clock. The best way to reset an atomic clock is to leave the batteries inside the clock but remove them from their compartment. This drains all power from the clock’s built-in battery backup. Once this is done, the internal clock takes about 10 minutes to develop enough ability to acquire its radio signal and reset itself with the correct time.

4. Resetting Before Updating Time:

Some people also mistakenly believe that they need to reset their atomic clock before updating the time. This is not necessary either. The clock will update itself automatically when it receives the new time signal.

5. Turning Off Clock:

Another common mistake people make is turning off their atomic clock when they reset it. This is not necessary and can damage the clock. The best way to reset an atomic clock is to leave it on and unplug it from the wall.


The atomic clock has reset, but what does that mean for you? If your Sharp atomic clock is set to the time zone of Eastern Standard Time, Central Daylight Savings Time, or Pacific Standard Time, then it will automatically update itself. So you don’t need to do anything other than making sure the date and time are correct on your device.

However, if your Sharp atomic clock is set to a different time zone, such as GMT+0, you should manually adjust it by turning off daylight savings mode before setting up the new year’s date and hour. Now that we’ve answered all of your questions about how to reset a sharp atomic clock, this will ensure your alarm is set for when you need it most.
