WHAT IS AN ATOMIC CLOCK?
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.
BASIC SETUP
-
Battery Installation – BEGIN WITH THE OUTDOOR WIRELESS SENSO
-
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 -
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 (s) 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 & Temperature Range:
extended periods of extremely 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 the 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.
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 or both of
the units. If most or all 4 of the bars are present, wireless reception is
good and no action is required.
SETTING THE CLOCK MANUALLY
-
SETTING YOUR TIME ZONE
a) Press and HOLD the SET button until you see the selection of seven time zones Then RELEASE.
b) Press the UP ( ) ARROW repeatedly until you reach your time zone, then press SET and release. -
TURNING ATOMIC CLOCK FEATURE ON/OFF
NOTE: You do NOT need to turn off the atomic clock to set the time manually. Once the clock receives the signal, it will adjust the clock accordingly. However, you may choose to deactivate the atomic clock feature completely if you prefer to manually control the clock or if you live in a remote area that does not readily receive the atomic signal. As long as the atomic clock is ON, it will automatically adjust itself to the correct time, overriding your manual setting.
Press the UP ( ) ARROW to or DOWN ( ) ARROW buttons to turn OFF the Atomic signal. This will stop the clock from searching for the Atomic radio signal. -

TROUBLESHOOTING
PROBLEM POSSIBLE SOLUTIONS
Poor Atomic Clock Reception — (No bars)| Relocate or reposition the clock,
making sure the backside of the unit is facing in a direction toward Colorado
from your location.
Heavy stone or metal walls can obstruct the signal and disrupt reception.
Place the clock at least 3 feet (0.91 m) from other electronic devices (i.e.
N’s, microwaves, computers, etc.) that can interfere with wireless signals.
Poor Outdoor Sensor Reception (No bars) | You may be experiencing interference
from other wireless devices using the same radio frequency channel. Relocate
the main unit and/or the wireless sensor. Both units must be within 100 feet
(30m) of each other. Make sure units are placed at least 3 feet from other
electronic devices or appliances that may interfere with the wireless
communication(i.e. N’s, microwaves, computers, etc.)
You may need to reset both units by removing and re-Installing the
batteries.
Bad temperature Reception (blank or flashing temperature)| Relocate the main
unit and/or the wireless sensor. Both units must be within 100 feet (30m) of
each other. Make sure units are placed at least 3 feet from other electronic
devices or appliances that may interfere with the wireless communication (i.e.
N’s, microwaves, computers, etc.)
You may need to reset both units by removing and re-Installing the
batteries.
Display Not Working| Check to make sure the batteries are installed correctly.
Use only fresh STANDARD “AA” batteries, not generic or extra strength. Make
certain that the batteries are FRESH If the expiration date on your batteries
is less than 6 years away, they may not contain a full charge and can be weak.
