it will show an arrow and that will scroll from temperature and humidity. When pressed
again then it will stay on temperature.
•When replacing batteries for the remote sensor, remember to clear the corresponding
channel of the main unit in this way: Select the respective channel by pressing the
CHANNEL button then by holding the CHANNEL button for 3 seconds to clear the
registration.
*Note: The “TX” and the “C/F” are hidden inside the protective backing to ensure weather
resistance of this unit that is intended for outdoors. The remote sensor(s) are not “waterproof”
meaning able to submerse, but rather water resistant or weather resistant. Prolonged exposure
to cold weather may cause damage to the LCD panel and in addition can drain your batteries.
Extreme heat can cause your batteries to drain and more importantly, explode and corrode in the
compartment. Battery corrosion will harm the unit. Although these units are intended for
outdoor use, placing them in a protected are will preserve the life of the unit.
About the Atomic Clock:
The National Institute of Standard and Technology (NIST) in Fort Collins, Colorado broadcasts
the time signal (WWVB at 60kHz radio signal) with an accuracy of one second per every 3,000
years. The signal covers a distance up to 2,000 miles from the source.
Selecting the Ideal Location:
Like a typical AM radio, the atomic clock will not receive the WWVB signal in places surrounded
by heavy concrete or metal panels. For best reception, please install the home receiver near a
window. The tie signal reception is also greatly affected by electrical or electronic interference.
If the home receiver location you selected does not work, change to a location in another part of
the room or building.
Radio Controlled (R/C) Time Reception Set Up:
The clock attempts to synchronize with the Atomic time signal automatically right after the first
remote sensor is registered. The unit starts synchronizing the clock after registering the remote
sensor thermometer reading. The clock will not respond to any manual settings while attempting
to receive the Radio Control Time signal. This reception cycle will last from 2 to 5 minutes. The
tower icon in the right hand corner of the screen appears fixed when reception is successful. It
can take the main unit 24 to 72 hours to receive the atomic time signal. To turn the reception
off and to enable manual settings, press the SET button.
Entering the Time Zone:
Press and hold the “-C/F(zone)” button for 3 seconds the letter P will appear where the seconds
are, then press and release the “-C/F(zone)” button until the correct letter for your time zone
appears. The four time zones are P is Pacific, M is Mountain, C is Central, and E is Eastern.
Press the SET button to confirm or leave the setting to confirm and exit automatically.
How to Manually Synchronize your Atomic Clock:
Press the SET button to trigger a manual synchronization. The tower will flash regularly during
synchronization. Signal strength level is indicated in this way below:
1. Very Weak or no signal (1 icon)
2. Weak (2 icons)
3. Good (full icon)
4. Icon appears fixed and does not blink (reception successful)
5. Icon does not show (no signal received)
