Interference:  

 

Consider items in the signal path between the remote sensor and the atomic 

clock.  

 

Sometimes a simple relocation of the remote sensor or the atomic clock will 

correct the interference. 

 

Windows can reflect the radio signal.  

 

Metal will absorb the RF (radio frequency) signal. 

 

Stucco has a metal mesh that absorbs signal. 

 

Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports, 

military bases, etc.) 

 

Electrical wires (utilities, cable, etc.) 

 

Vegetation is full of moisture and reduces signal. 

 

It is difficult for RF (radio frequency) signal to travel through a hill. 

 

Atomic clock 

Power Requirements 

 

 

2-AA alkaline batteries may be used. 

 

12-Hour time format 

 

 

Time can display in 12-hour only  

 

Fahrenheit/Celsius 

 

 

  Use th

program menu 

to switch between Fahrenheit and Celsius. 

 

Moon Phase 

 

The moon phase is based on the lunar calendar and the year, month and date set. 

Most Internet moon phase calculations are based on the lunar calendar.

  

 

 

Waxing indicates growing or expanding illumination and happens after a new 

moon. 

 

Waning indicates decreasing illumination and occurs after a full moon. 

 

Crescent refers to the moon being less than half illuminated. Crescents can be 

waning or waxing. 

 

Gibbous describes a moon phase when more than half is illuminated. Gibbous 

can be waxing or waning. 

 

New Moon occurs when the moon is between the earth and sun, so the 

illuminated portion of the moon is on the back side facing the sun and we cannot 

see it. After a new moon, the illuminated portion will increase or wax until the 

full moon occurs. 

 

Full Moon occurs when the earth, moon and sun are in approximate alignment, 

with the moon and the sun on opposite sides of the earth. The illuminated 

portion of the moon faces the earth, giving us complete visibility of one side of 

the entire moon. After a full moon, the illuminated portion will decrease or wane 

until the new moon occurs.
