What You’ll Need:
(8) AA Batteries


An Atomic clock is a timepiece that maintains accuracy up to one second per million years using the most precise method of time synchronization, radio signals. In North America, the National Institute of Standards and Technologies (NIST) operates an Atomic clock in Fort Collins, Colorado, that transmits the time codes via the radio station WWVB.

This quality TIMEX ® clock includes a built-in receiver that picks up the Atomic radio signal from WWVB. To maintain the best possible reception, place the unit so that the backside faces in the general direction of Colorado. What’s more, the IntelliTime ® technology built into this clock makes for hassle-free automatic setting and resetting for daylight saving time.

PLEASE NOTE: Due to solar radiation in the atmosphere, the atomic clock signal is weaker during the day. Most synchronization will happen at night when there is less interference.


  2. Initial Setup – once the batteries are installed, the clock will power up. The display will appear as follows:
    The clock will initially set itself to the correct time and date, defaulting to EST (Eastern Standard Time). It will also begin displaying the temperatures. The clock will begin searching for the Atomic signal.
    Note: The clock will adjust for daylight saving time, even if it is unable to receive the WWVB signal
    After the clock acquires the Atomic signal (this may take 24-48 hours) the time, date and daylight saving time changes will update automatically, giving you maintenance-free operation and accuracy to the split second
  3. Choosing Your Time Zone
    1. Press and HOLD the SET button until you see the selection of seven time zones flashing on the LCD screen then RELEASE.
    2. Press the UP ARROW repeatedly until you reach your time zone, then press SET

In the event you wish to manually change the clock settings, please use the instructions on page 5.

Battery Choice and Temperature Range:

extended periods of extreme cold temperatures (below -4°f/ -20°c) can cause alkaline batteries to function improperly. this may cause the outdoor wireless sensor to stop transmitting temperature readings. we recommend using lithium batteries in extreme low temperature conditions to ensure continued operation of the outdoor sensor.

For the digital atomic clock we recommend only alkaline batteries.

Placement of the Clock:

Place the clock in an area free of dirt and dust. To help ensure an accurate indoor temperature measurement, be sure to place the main unit out of direct sunlight, and away from any heat sources or vents in your home.

This clock may be hung on a wall using the integrated wall-hanging hole, or you may place the unit on a tabletop or other fat surface using the swing-out stands.

Placement of the Outdoor Sensor:

The wireless temperature sensor MUST BE PLACED OUTDOORS to capture and relay the outdoor temperature to the clock display unit. You may place your wireless temperature sensor outside up to 100 feet (30m) from the clock, as shown.

The sensor is water resistant and is designed for outdoor use. However, to extend the life of the product, place it in an area protected from harsh weather elements. To ensure an accurate temperature reading, be sure the sensor is out of direct sunlight and away from any heat sources.

Future Forecast Icon

The future forecast feature automatically gives you the predicted weather forecast icon for the next 12 to 24 hours based on an advanced algorithm that analyzes barometric pressure changes and temperature. This weather forecaster will provide the most accurate forecast that a single stations instrument can provide.

Weather Trend Icon

The “Weather Trend” directional arrow icon will indicate one of three barometric pressure trend directions. This will give an additional indicatin of future weather conditions

Wireless Signal Reception Icons

The main unit has a signal reception icon near the outdoor temperature display area. If there are a low number of “bars” present, you may experience no temperature display (“–”) or inaccuracy. In either case, you may need to relocate one of both of the units. If most or all 4 of the bars are present, wireless reception is good and no action is required.
