November 2005

Hans wonder if an inexpensive wireless door bell transmitter might disturb modern wireless car locks. The answer is yes! The transmitter in this unit sends a broad signal blocking the ordinary key when it uses the public frequency 433 MHz.

He buys a wireless door bell set for only 99 SEK at Rusta. The set includes both the door bell and the transmitter, including its 12 V battery.
