If you have radio equipment, electrical products or fixed installations that interfere with or are interfered with by other electronic products, you should report them to the Federal Network Agency. Dangerous radio equipment can also be reported to the BNetzA.

In principle, the Federal Network Agency randomly checks radio equipment and electrical products from the areas of household appliances and power tools, lighting, IT products, consumer electronics or radio equipment including products with integrated WLAN or Bluetooth. These can be, for example:

• Mixers or drills that interfere with radio reception, for example
• LED lights that interfere with radio reception,
• Radio alarm clocks that cause interference to the radio,
• Radio headphones that cause radio interference or
• Interfering transmitters or jammers that deliberately make mobile phone reception on trains or in cinemas impossible.
• Smartphone or cell phone with dangerous charging cable or power supply unit

During the inspection, the Federal Network Agency checks, for example

• whether the CE mark on the product is present and correct,
• whether the device bears a type, batch or serial number or other information by which it can be identified,
• whether the manufacturer's information or introduction information is correct,
• whether the product is accompanied by German operating instructions with instructions for use and warnings,
• whether a correct declaration of conformity (for radio equipment) is available, which proves that the product complies with the applicable regulations,
• whether the product can cause radio interference or is inadmissibly interfered with by other products,
• whether the radio equipment complies with device safety,
• whether the product violates personal rights, for example because it can transmit sound or images unnoticed.

You can sometimes recognize that a product is dangerous or does not meet European requirements before you buy it. But even if you only notice the defect later, you should report the product.
