The receiver unit has a clear, easy-to-read display that shows indoor temperature and humidity, outdoor temperature,
time, month, date, day. The remote sensor transmits the outdoor temperature. To receive the outdoor temperature,
place the sensor anywhere within 30 meters; the 433.92MHz technology means no wire installation is required.
The Atomic Clock will always be accurate to within one second as it receives daily WWVB updates. Daylight Saving
Time also automatically updates so there is no need to re-set the clock manually!
IMPORTANT: If the Atomic Clock does not receive the WWVB signal immediately, wait overnight and it will be
set in the morning.
The clock has a built in receiver that automatically synchronizes itself with the WWVB radio signal broadcast by the
US Government's National Institute of Standards & Technology (NIST) in Fort Collins, Colorado.
signal daily broadcast ensures that the atomic clock will always display the most accurate date and time.
. QA Clock:
- Before insert the battery, select the time zone and DST mode. Once battery is inserted, the second hand will run
and stop at zero position (12:00), and then the minute and hour hands will start running and stop at zero position.
Then, the clock begins to receive the Atomic time signal automatically and it will take 3 - 10 minutes. If successfully
receive the signal, the hands will find their correct time and work normally.
1. The unit will automatically search for the time signal at 2:16am, 4:16am, 2:16pm, 4:16pm.
2. Closed area such as airport, basement, tower block or factory is not recommended.
3. While the atomic signal is flashing, the control panel is inactive.
2. LCD DISPLAY:
- Displays indoor/outdoor temperature; and current weather condition.
3. BATTERY COMPARTMENT AND DOOR:
- Use 2 x AA size batteries
4. ℃/℉ BUTTON:
- In normal mode, press the button to switch temperature unit ℃/℉.
