3.2 Initial Time Setting (Radio Wave Reception)

The clock is designed to automatically receive standard radio waves to set the correct time. For optimal reception:

• Place the clock near a window where it can easily receive radio signals.
• Avoid locations that generate strong radio interference, such as:
  • Inside buildings, deep within rooms, or basements.
  • Fast hochvoltage power lines, TV towers, or train tracks.
  • Close to electronic appliances like TVs, refrigerators, air conditioners, air purifiers, computers, or fax machines.
  • In vehicles (cars, trains, airplanes).
  • Over or near metal furniture like steel desks.

If radio waves are not received, the clock will operate with standard quartz accuracy. Manual time adjustment may be necessary in areas with poor reception.
