My dell latitude d820 will not keep eastern standard time. it reverts within 5 minutes of setting the correct time. it is killing my calendar synch with my blackberry enterprise operated handheld

Resetting: 1. Remove batteries from both the outdoor transmitter and the Temperature station. 2. Wait at least 30 seconds and then repeat the procedures specified in Setting up (above). Note: Always wait at least 30 seconds after removing the batteries before reinserting, otherwise start up and transmission problems may occur. Also, remember when insertting, that both units have to reset and to always reinsert the batteries to the transmitter first

Instructions

1. • 1 Insert the batteries into the clock and verify that the clock's display is functioning.
     
   • 2 Set the correct time-zone and Daylight Saving Time (DST) switches. The switches are on the back of the clock. Select EST if you are in Eastern Standard Time, CST if you are in Central Standard Time, MST if you are in Mountain Standard Time, or PST if you are in Pacific Standard Time. The DST selector should be set to "off" or "on" depending on the laws of your state.
     
   • 3 Wait 15 minutes. The clock should synchronize automatically.
     
   • 4 Set the clock manually using the buttons on the back panel if the clock does not catch the radio signal within the first 15 minutes. Push the correct button to advance the month/day/year on the calendar; use the MODE button to set the hour and minute.
     
   • 5 The clock should adjust itself within 48 hours to match the atomic signal. Verify that the clock is receiving the signal by checking the front display. You should see the image of a tower with circular lines at its top.

Hello
To adjust time follow this.

Auto-Set Time and Date Settings

This model is equipped with the Auto-Set feature, meaning that the time and date have been programmed at the factory

and will already be set when you first plug the model in. Auto-Set will automatically adjust the time and date settings for

daylight-saving time and leap years. Auto-Set is programmed for Eastern Standard Time; if you do not live in this time zone,

you can easily switch the setting to one of six other time zones.

1. To change your time zone setting, press and hold the 8 Time Zone Button. The current Auto-Set Time Zone in the

lower-right-hand corner of the display will flash for approximately ten seconds, after which the display will revert to the

standard clock display.

2. While the Auto-Set Time Zone is flashing, press the 1 Reverse and 6 Forward Buttons to select your time zone.

The display will show each zone's current time setting. There are seven zones to choose from:

Auto-Set Time Zones

Z-01 Atlantic Standard Time

Z-02 Eastern Standard Time

Z-03 Central Standard Time

Z-04 Mountain Standard Time

Z-05 Pacific Standard Time

Z-06 Alaskan Standard Time

Z-07 Hawaiian Standard Time

3. Find your time zone, then press the 4 Enter Button or wait about ten seconds for the clock to beep twice and the

setting to lock into place.

Manual Time and Date Settings

1. To change your time setting, press and hold the J Time Set Button so that the clock display begins flashing.

2. While the display flashes, press the 1 Reverse and 6 Forward Buttons to set the time. Hold a button for a few

seconds to set the time rapidly. Be sure to set the correct AM/PM time, shown by the PM Indicator.

3. After setting the time, press the 4 Enter Button or wait about ten seconds for the clock to beep twice and the setting

to lock into place.

4. To change the calendar, press and hold the 9 Date/7-5-2 Button until the display shows the flashing year.

5. Press the 1 Reverse and 6 Forward Buttons to set the current year. When you have selected the year, press the

4 Enter Button, then use the 1 Reverse and 6 Forward Buttons to set the month/day.
6. After you have set the date, press the 4 Enter Button or wait for the display to beep twice and lock into place.

You may need to change the coin cell battery as well, it sits under the memory module cover. It's usually covered in a little blue plastic coating and has a red and black wire coming from it to a small white plug. You should be able to get a replacement for it at your local Radio Shack or electronics store. This battery is what keeps the time and date current on your machine.

Normally, the solution is to replace the keyboard, they run about $20 on ebay and takes about 15 minutes to change.

Duh... I figured out that my PC had the date set a month ahead! Not sure how that happened. The Axim was dutifully synching up w/ the wrong date, and so the November appointments didn't register. Thanks for checking.
