Antitheft System - Interruptions In Radio Operated Systems
Date: September 22, 2010
Order No.: V-B-80.57/01
Group: 80
SUBJECT:

Interruptions in Radio-Operated Vehicle Systems
In the frequency range of the transmitter key or KEYLESS-GO, many other radio-operated systems can also be transmitting and with a stronger
signal. Systems such as, radio frequency headphones, radio thermometer, garage door opener, alarm systems, etc. can prevent or interrupt
unlocking, locking, and engine starting via a KEYLESS-GO.
Fortunately, in parallel with radio remote control, most MB vehicles also have infrared remote control, so that even with radio disturbance, the
transmitter key will unlock and lock at short range. Exceptions are the 903 and the 904 as they do not have additional infrared remote control, but
the mechanical key will always work.
Advise customers that taking a vehicle key is always recommended as it is conceivable that a criminal might use a radio interferer to block the
locking of a vehicle. Locking is ensured by 3-signal flashing.
