  Sometime a simple relocation of the transmitter or the Digital Atomic Clock will correct the 

interference issue. 

  Windows can reflect the radio signal.  

  Metal will absorb the RF (radio frequency) signal. 

  Stucco is held to the wall by a metal mesh. 

  Transmitting antennas (ham radio, emergency dispatch center, airports, military base etc.) 

  Electrical wires (utilities, cable etc.) 

  Vegetation is full of moisture and reduces signal. 

  Dirt: Trying to receive a signal through a hill is difficult.

Digital Atomic Clock 

 
How tall are the Time Numbers? 
 
The time numbers are 2 1/8 inches tall. 
 
Supported Time Zones 
 
This Digital Atomic Clock offers seven time zones: 
 

  AST=Atlantic 

  EST= Eastern 

  CST= Central 

  MST= Mountain 

  PST= Pacific 

  AKT= Alaska 

  HAT=Hawaiian  

The Digital Atomic Clock is designed to work in North America.
