1. Slide the SETTING switch to TIME SET or CALENDAR SET to set the time or calendar.. 2. Press the UP and DOWN button to change the value and press ENTER button to confirm the setting.

If it is necessary to set the clock manually, press and hold the SET button for 3+ seconds to activate the manual mode. Once the clock is in manual mode, there are two ways to move the minute hand forward. Hold the SET button down to move the minute hand forward consistently.

Test and replace the battery in the clock, if required. Low batteries are often the cause for weak reception. Relocate the clock. It is possible the clock is in an area with a lot of wireless interference.

Press and hold the ALARM button for 2 seconds to enter the alarm set mode. Press + or – to adjust, then press ALARM to confirm and move to next feature. ZONE / DST ON / OFF Press to select the current time zone: PST, MST, CST or EST. Hold the ZONE button for 2 seconds to switch from DST ON to DST OFF.

It will start receiving the Atomic time signal within 10 minutes. Once received the signal successfully, the clock hands will found the correct time and run normally. Otherwise, it will return to the time before Force Receiving. If the Atomic signal is not received wait over night and it will be set in the morning.

MANUAL TIME SETTING If your clock does not automatically set itself within 24 hours after inserting the battery, it is probably due to poor signal reception. Your clock may need to be moved to another location where there is better signal reception.

The WAVE button can be used to force signal reception. To activate, hold the WAVE button down for 3+ seconds. Once the WAVE feature is activated, the hands will automatically reset to the 12:00 position and the movement will attempt to receive the WWVB signal from Fort Collins, CO.

La Crosse Technology atomic clocks set their time automatically by synchronizing to a radio signal called WWVB that the National Institute of Standards and Technology (NIST) broadcasts continuously from Fort Collins, Colorado.

Windows: Right-click the system clock in the lower right-hand corner of the display and click on the “sync now” button. Your system will contact a time server and adjust the system clock, if needed.

Luckily, the atomic clocks on GPS satellites, due to their incredible stability and regular synchronization, maintain an error of less than 1 billionth of a second. Today, the best clocks scientists are working on can do even better -- more than a million times better by some measures.

To create a clock, cesium is first heated so that atoms boil off and pass down a tube maintained at a high vacuum. First they pass through a magnetic field that selects atoms of the right energy state; then they pass through an intense microwave field.

1. Hold the SET button to enter time set mode. 2. Press the WAVE/+ or DST/- buttons to adjust values.

Windows: Right-click the system clock in the lower right-hand corner of the display and click on the “sync now” button. Your system will contact a time server and adjust the system clock, if needed.
