27.175 27.185 27.205 The COBRA 29 WX ST has a vastly superior receiver which includes noise blanker circuitry and an automatic noise limiter. The receiver also features increased protection against cross modulation and strong adjacent channel signals. To obtain maximum performance please read carefully the descriptions and operating instructions in this manual.
Installation Location Plan the location of the transceiver and microphone bracket before starting the installation. Select a location that is convenient for operation and does not inter- fere with the driver or passengers in the vehicle. In automobiles, the transceiver is usually mounted to the underneath of the dash panel, with the microphone bracket beside it.
Even though the COBRA 29 WX ST has an automatic noise limiter, in some in- stallations ignition interference may be high enough to make good communica- tions impossible. The electrical noise may come from several sources. Many pos- sibilities exist and variations between vehicles require different solutions to reduce the noise.
