- Close to electronic appliances like TVs, refrigerators, air conditioners, air purifiers, computers, or fax machines.
- In vehicles (cars, trains, airplanes).
- Au-dessus ou à proximité de meubles métalliques comme des bureaux en acier.
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.
