In what environment does my radio-controlled watch/clock receive standard electric wave?

Does my radio-controlled watch/clock keep receiving standard electric wave all day?

Your radio-controlled watch/clock does not keep receiving the radio wave all day but passively receives the radio wave at fixed times in a day.

Will my radio-controlled watch/clock stop when it fails to receive standard electric wave?

Your radio-controlled watch/clock will not stop because it does not run via radio waves but is battery-operated or solar-powered. In a poor reception area or outside the service area, such as overseas, it can be used with accuracy of a regular quartz watch/clock.

What are good reception environments and poor reception environments?

Good reception environments

• From midnight to morning
  
• Wooden house
  
• Near a window
  
• Antenna aimed at standard radio wave transmitting station(*)
  * Since the antenna position varies with products, check the instruction manual, etc.
  
• Place with a fine view where there is no tall building in the neighborhood
  
• Fine day
  

Poor reception environments (reference)

The followings are places where the radio wave cannot be received easily.
Select a good reception environment to use your radio-controlled watch/clock.
Even at the same place, the radio wave may not be able to be received in bad weather, like a thunderstorm, or depending on the time, season, etc.

1) Near home electrical appliances or OA equipments (TV, speaker, fax, PC, etc.)	2) Near a construction site or airport, heavy traffic area, etc.	3) In a vehicle(car, train, airplane, etc.)
4) In and around a ferroconcrete or steel-frame building, such as a condominium * However, it becomes easier to receive the radio wave when your radio-controlled watch/clock is placed near a window.	5) Near high-voltage cables or overhead wires	6) On a metal plate, behind a mountain, etc.

Avoid the above places for reception. If the reception is still poor, change the direction or place.

A radio-controlled watch may experience poor reception while it is being worn. In such a case, take it off, and allow it to receive the radio wave without moving it in a good reception environment.
