Radio Receiver

Sources Of Disturbance In Radio Remote Control Operation

When operating properly, the remote control has a range of approx. 15 m.

Legal requirements have defined the frequency range for radio remote control operation to be 433.92 MHz or 315 MHz (e.g. USA, Canada, Australia).

A series of radio-based systems operate within this frequency range so that they can mutually interfere with each other under certain physical conditions.

Interference caused by these transmitters can result in a reduction in range or in temporary complete failure of the radio remote control.

Interference sources
The following devices can disrupt operation of the radio remote control:
- Cordless headphones (headset for radio systems)
- Radio-based devices, radio remote controls
- Radio modems
- Telemetry transmitters, e.g. weather stations with external temperature sensors
- Alarm systems with radio monitoring
- Garage door openers (radio systems)
- Remote controlled socket outlets
- Radio-based chime systems
- TV systems

Fault detection
As a rule, an interference transmitter is active if the remote control does not function at all or temporarily in certain locations.

Under certain circumstances, the interference transmitter can be suppressed by holding the key-chain transmitter very close to the antenna (at a distance of approx. 10 cm).

No technical remedy is possible in this case. Vehicle customers should be informed of these technical conditions.
