Try relocation the clock or the transmitter if the clock does not display the outdoor temperature after 6
minutes.
The RF Temperature signal indicator in the clock's outdoor temperature window will show the following:
Atomic Clock Reception
Your atomic clock receives the offical US time signal from the US Atomic clock in Ft. Collins,
Colorado.Successful reception will activate the WAVE OK icon. If the clock fails to receive the "WAVE"
signal in the first reception sequence after power up, it will repeat a 10-minute reception sequence every
30 minutes. This operation stops once the WAVE is received. The clock automatically refreshes the
WAVE each night.
You can start reception of the time signal anytime by pressing the TIME WAVE button.
Note: Frequent use of this feature may affect battery life.
Interference
Signals from other household devices, such as entry controls, door bells and home security systems, may
temporarily interfere the Atomic Clock and cause reception failure. This is normal and does not affect the
general performance of the product. The transmission and reception of temperature reading will resume
once the interference has stopped.
Manual clock setting
If 20 minutes after power up your clock has not successfully received the time signal, you may set the
clock manually or the clock will continue an automatic search each 30 minutes until the signal is received.
Best reception of the WAVE is during the nighttime when the atmosphere allows a stronger signal to travel
farther from the Colorado transmitter. It is strongly recommended that you allow the atomic clock one
or two evenings to automatically catch the WAVE and set itself.
If you decide to manually set the clock make sure the time zone and DST switches are properly set (see
getting started). Then follow these easy steps:
1.Slide the switch to TIME SET and the time will flash on the display. Press the HR and MIN  
 buttons until you reach the desired time.
2.Slide the switch to calendar and the year and date will flash on the display. Press the YEAR,  
 MONTH and DATE buttons until you reach the desired calendar setting.
3.Slide the Switch to the LOCK Position.
4.Press the 12HR/24HR button to choose the desired display format. "AM"and "PM" display only  
 in the 12HR format.
5.Press the C/F button to choose the Centigrade or Fahrenheit scale. Both the indoor and outdoor  
 temperature will display in the chosen scale. Note: the display on the remote unit can also show  
 Centigrade or Fahrenheit independent of the temperature scale chosen for the clock display.
Losing Synchronization of the wireless thermometer and the clock:
If the clock displayed a proper outdoor temperature in the past but now displays blank "--", the wireless
transmitter and clock may have lost synchronization. If this occurs, press the TEMP FINDER button
behind the flip over stand of the clock. The clock will attempt outdoor temperature reception for another 6
minutes and reinitiate synchronization with the wireless transmitter. If the remote temperature cannot be
received, check:
1.The distance of the Atomic Clock or Wireless Transmitter should be at least 3-4 feet away from any  
interfering sources such as computer monitors or TV sets.
2.Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3.Using other electrical products such as headphones or speakers operating on the same signal frequency 
(433MHz) may prevent correct signal transmission and reception.
4.Neighbors using electrical devices operation on the 433MHz signal frequency can also cause interference.
Note: When the 433MHz signal is received correctly, do not re-open the battery cover of either the wireless
transmitter or the clock, as the batteries may spring free from the contacts and force a false reset. Should
this happen accidentally then reset both units (see Getting Started above) otherwise transmission problems
may occur.
The maximum transmission range is 100 feet from the wireless transmitter to the atomic clock (in open
space). However, this depends on the surrounding environment and interference levels. If no receipt is
possible despite the observation of these factors, all system units have to be reset (see Getting Started).
Wall Mounting or Using the Stand
The main unit has a built in stand you can flip open to support the main unit on a flat surface. You can close
the flip and mount the unit on a wall. Drive a screw into the wall until the head extends about 1/8 inch from
the wall, then locate the keyhole slot over the screw head and slide the Atomic Clock down to make it
secure.
Trouble - Shooting
•Press the "Reset" button when the clock is displaying irrelevant time even when the tower icon shows.
This may happen when the external noise is severe enough to interfere with the time signal.
•Press the "Reset" button on the wireless transmitter if the readout is irrelevant or does not respond.
