TO INSTALL AND REPLACE BATTERIES IN THE ATOMIC CLOCK The atomic clock uses 3 x AA, 1.5V batteries. To install and replace the batteries, please follow the steps below: Pull down on the tab at the top of the battery cover and lift up to remove the cover.
: To activate the snooze function during alarm ATOMIC CLOCK LCD SCREEN DESCRIPTIONS The atomic clock's LCD is divided into 2 sections and once the batteries are inserted, all the segments will light up briefly before displaying the information for time, date, indoor temperature, indoor humidity, and second.
After completion of the above described procedures in “Setting up” the manual setting modes can be entered by pressing and holding the SET key for 5 seconds. The following settings can now be programmed: • LCD contrast setting • Time zone setting •...
Press and release the + key to select the desired time zone. Press and release the SET key to confirm the time zone setting and continue to the DST (Daylight Saving Time) setting. Note: The time zones from –4 to –10 hours will be displayed with 3 characters abbreviations: •...
In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the time can be manually set. The clock will then work as a normal Quartz clock. The hour digits will start flashing in the upper LCD.
When the time signal is received for example at 1:00 am, the atomic clock will not attempt to receive the WWVB signal for the remaining hours until 6:00 am. Therefore, the next signal attempt will take place between 12:00 am and 6:00 am the next day.
To return to the normal display mode from anywhere in manual setting mode simply press the ALM key at anytime. • If no keys are pressed for at least 15 seconds in setting mode, the atomic clock will automatically switch back to normal display mode. ALARM SETTING To enter into the alarm setting mode: Hold the ALM key for 5 seconds.
Cesium 133 atom in a vacuum. This atomic clock regulates the WWVB transmitter. The WWVB tower icon in the clock display will start flashing in the top center of the LCD. This indicates that the clock has detected a radio signal and is trying to receive it. When the time code is received, the WWVB tower becomes permanently lit and the time will be displayed.
Gibbous POSITIONING Before permanently mounting ensure that the atomic clock is able to receive WWVB signals from the desired location. Also, extreme and sudden changes in temperature will decrease the accuracy of the atomic clock, and changes in elevation will result with inaccurate temperatures readings for the next 12 to 24 hours.
Problem: No reception of WWVB signal Solution: 1) It may help reception to face the front of the atomic clock in the general direction of Ft. Collins, Colorado. 2) Wait overnight for signal. 3) Be sure the atomic clock is at least 6 feet (2 meters) from any electrical devices, i.e.
• When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or scouring agents. • Do not submerge the unit into water. • Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended size.
