Sharp Atomic Clock Daylight Savings

My Sharp Atomic Clock doesn't seem to want to change for Daylight Savings. My other Atomic Clock changes just fine so I know I'm getting a signal. Any Idea how I can do this manually? I can't seem to find it by going through all the buttons on the back.

    We just experienced the same thing: clock apparently not aware of recent changes to daylight savings schedule, instruction manual gone missing. As with any modern electronic gizmo, the first step is to try removing and reinstalling the batteries (a "cold boot", in computerese). No luck this time. So I tried again, this time pressing the little MT button on the back for mountain time, instead of PT for pacific time. Now the clock has advanced an hour. Its a work-around, and if the clock later decides to make the daylight time adjustment, we will have to revert to pacific time. If you are in the eastern time zone, I can't help ya.

    Sharp atomic clock won't reset to daylight savings, took out battery and now it isn't running at all!

  • abuyer2 Mar 13, 2009

    The Sharp Atomic clock resets only using the old time savings schedule. You'll see that in two or three weeks it will change time. The only way to fix this is by updating whatever "programming" the clock has inside. The clock is probably too cheap for Sharp to bother making any change available.

    Exactly the same as the previous one. My Sharp WWVB seems to have no way to turn daylight savings time on or off. On the back there are 4 time zone buttons, a smaller button with no markings and a 'reset' button.

    I have a somewhat large clock, and it also has the 3 buttons for time zones in the back. I had no idea what the leverage button was until someone described it to me. Seems if you depress it slightly, the second hand moves, and if firmer (all the way in) the minute hand spins. Had I know this life would have been a lot easier. but my wife bought the clock and no one knew where the directions were. thanks so much to the original person who answered how to get this things working again.

    Bless you!

    I have read the posts. We're past ALL day light saving's times dates. I tried the reset button. Our clock went to 12:00 for a few minutes and then started running at the update signal and went to standard time again. Clearly, the satellite hasn't been updated. So, what are we to do? The last time that time changed, we only had to wait for the original time change, and our clock corrected itself as someone else said it would, but this time, we have no such luck. Any suggestions?

I have the Sharp digital atomic clock, model SPC373. I bought it at a thrift store for a few bucks and don't have the manual. This morning (11/1/2009) it was still reading DST and hadn't set itself back an hour, so I pushed the "receive" button on the back. The little satellite dish icon did its animation thing (like it's receiving a signal) and after a couple of minutes, it reset itself to the correct time. In my opinion, DST is ridiculous and causes more trouble than it's worth! Half the world doesn't even bother with DST! Now that we have this "atomic clock" technology, maybe the worldwide department of standards can come up with a clock that just drops or adds a couple of minutes throughout the year to achieve the same effect as DST without drastically disrupting our circadian rhythm twice a year! (Similar to what they did in ancient times.) Or maybe we can just live with the fact that the sunrise and sunset, shifts throughout the year and not make such a big deal over it! The "developed world" only just started doing this DST thing in the beginning of the 20th century, it's really a new invention by historical standards. There is an interesting Wikipedia article about DST...check it out. (And good luck with your "modern technology" clock!)

I put fresh battery in and the clock set itself to 12:00, I didn't touch anything, and it stayed in that mode until it set itself by radio signal during the night.

The following morning the clock appeared to be set for Pacific Time, I pushed the "E T" button on the back, and the clock set itself to eastern daylight savings time by itself.

c7y_badge_rn_1._v47060296_.gif I called Sharp Electronics (about the failure of the clock to detect the new 2007 daylight savings time), and it turns out Sharp Electronics is a different company then Sharp who sell/support the atomic clock. I got the number for this company and these are the instructions for updating the clock's time (should work in any time zone).
1) Pull the batteries and wait a few minutes.
2) Put batteries back in - time will set to 8:00 (or possibly something different).
3) Press the "leverage button" (just above an to the left of the time zone buttons) and the clock hands will spin.
4) Release the leverage button when the correct time is reached.
5) Supposedly, this new time will track correctly and keep accurate time.
I asked what would happen next fall, and they said if if didn't track correct, steps 1 and 2 above should be sufficient.
Hope this helps - not the greatest time piece to be sure.

The carseat has obviously not been correctly installed using the seatbelt as it cannot be removed without undoing the seatbelt if it has been correctly installed. Contact your retailer for a demonstration on correct fitting.

How do I get the outdoor temperature to work on my Sharp Atomic clock, have replaced batteries in both clock and transmitter and reset numerous times

Hello jdb..... The outdoor transmitter needs to undergo a wee bit of maintenance. Remove those new batteries and clean the battery contacts with the eraser on the end of a common pencil. Then replace the batteries. IF you notice that the batteries slide in easily, use a small flat blade screwdriver to gently lift the battery contacts to increase the contact when you do slide the new batteries in. Joe

I changed the batteries in my atomic wireless thermo clock and now it wont give me out temp

The easiest way to fix this is to either take the battery out of the clock, which will reset the clock, or use a paper clip to press the reset button on the back of the clock.

My clock wont find the time.

I had to press receive on the back of mine until the satellite icon appeared on the top right. It's keeping time correctly now.'s the wrong time zone. We tossed the manual the other day so I'm stuck in Pacific Time instead of Eastern. Hope the top part of this helps. Tom Cassidy

Sharp Atomic Clock Model Number SPC 374T

I had the same problem last year and called the number on the back of the clock 718-610-2717 - it was busy forever - finally I got through and they gave me another number to call - I did get the problem fixed I just can't remember how exactly to fix it again. I think I had to manually reset...I have been trying the original number again - but it has been busy for the 4 days I have been trying. I will keep trying...

Resetting the atomic clock to the correct time zone, and outside temp to work.

For the Sharp SPC374T Atomic Clock - Time Zone setting- Press the 'Time' button once, the time zone will show where 'Day' usually is, use the Up or Down buttong to adjust.

For the outdoor Thermo, credit to my neighbor for this one. Remove battery from main unit, wait 2-3 minutes. Reload batteries. Once you get a reading from the outdoor sensor, hit the reset on the main unit. You will have to reset the time zone as described above, but this worked for me after 10 months of no outside temp showing up!

Good luck,
