UMEXUS B08CTZ5NH8 Atomic Digital Wall Clock User Manual

Important Information about Atomic Clock:

The atomic clock receives radio signals from NIST radio station WWVB near Fort Collins, Colorado right only at 1:00 am, 2:00 am, 3:00 am, 4:00 am and 5:00 am to set the correct time automatically. Therefore, you may need to set the time manually when you first use the atomic clock.

Set the Time Manually:

First, confirm whether the flickering signal tower icon appears at the top right of the screen, if so,  press the wave button to make the icon disappear, and then go to the next step of the settings, if not, go directly to the next step of the settings.

Step 1. Set the Time Zone: Press and hold the “SET” for 2 seconds to enter setting mode, the Time Zone display will flash. Use the “UP“ or “Down” button to select the correct Time Zone setting from the available able selections below:
PST – Pacific Standard Time
MST – Mountain Standard Time
CST – Central Standard Time
EST – Eastern Standard Time
AST – Atlantic Time
HAT – Hawaii-Aleutian Standard Time
AKT – Alaska Standard Time
Press the “SET” button to confirm.

Step 2. Set 12 or 24 Hour Time Mode: Use the “UP“ or “Down” button to set the time mode to either a 12 or 24 hour clock. Press the “SET” button to confirm.

Step 3. Set “Hour”: Use the “UP“ or “Down” button to set the correct hour. Press the “SET” button to confirm.

Step 4. Set “Minute”: Use the “UP“ or “Down” button to set the correct hour. Press the “SET” button to confirm.

Step 5. Set ”Year/Month/Date”: Use the “UP“ or “Down” button to set the correct date. Press the “SET” button to confirm.

Step 6. Set Daylight Saving Time(DST) ON/OFF: Use the “UP“ or “Down” button to choose. Press the “SET” button to confirm.

Notes:

1. The National Institute of Standards and Technology and WWVB encode a special DST “bit” in the WWVB transmission for DST.
2. This digital clock will read this information (only if “DST” is set to “On”) and automatically advance the time one hour in the spring and back an hour in the fall.
3. Arizona and Indiana: If you live in an area that does not recognize DST you must de-activate Daylight Saving Time by setting “DST” to “OFF”)

Step 7. Set Language: Use the “UP“ or “Down” button to choose. Press the “SET” button to confirm.

Wireless Outdoor Temperature Sensor:

Positioning the Temperature Sensor:
The Sensor is supplied with a holder that may be attached to a wall with screws or a rope.

• Mount in a sheltered place. Avoid direct rain and sunshine.
• Under the eaves of your home is an ideal place.

Notes:

1. Before permanently fixing the Sensor, place all units in the desired locations to check that the outdoor temperature reading is receivable.
2. If the signal is being received, the signal reception icon will be displayed on the Atomic Clock. In event that the signal is not received, relocate the Sensor or move it slightly as this may help the signal reception.
3. To ensure a good connection, there should be no more than 200 feet between the final positions of the Atomic Clock and the Sensor.
4. If the outdoor temperature does not display still, you can press and hold the WAVE button for 3 seconds until the signal reception icon   appear to enter the RF reception manually, which will sync the outdoor thermometer within 1 minute.

About WWVB Radio Signal Reception:

The clock enters WWVB radio signal reception mode automatically each time when the battery is installed. The reception mode can also be entered manually by pressing the WAVE button in the standard clock mode. The clock receives the signal from Collins, Colorado right on 1:00 am, 2:00 am, 3:00 am, 4:00 am, 5:00 am in the morning every day to sync the time, it will stop time syncing in 7 minutes no matter the time is synced or not.

Notes:

• The tower icon will be flashing when the clock is ready for receiving the WWVB radio signal. If the signal is weak or cannot be recognized correctly by the clock, the tower icon keeps flash for 7 minutes and disappear.
• When the signal is been receiving, the tower icon is stationary, and the antenna icon will be flashing. When the signal is successfully received and time synced, the icon will be displayed still.
• When the DST signal is received, the DST icon will be displayed.
• The signal level will be reduced, and the clock might not be able to sync if the clock is near a source of interference (like a computer monitor) or the clock is in a building with a metal roof. Please remove the clock from the interference sources and/or rotate it 90 degrees or mount it on a wall perpendicular to the one it is currently on.
