Specifications FREQUENCY RANGE The COBRA 25 LTD ST transceiver represents one of the most advanced AM two- way radios ever designed for use as a Class D station in the Citizens Radio Service. This unit features advanced Phase Lock Loop (PLL) circuitry providing complete coverage of all 40 channels as shown below.
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.
The unit requires very little current and therefore will not significantly discharge the vehicle battery. Even though the COBRA 25 LTD ST has an automatic noise limiter, in some instal- lations ignition interference may be high enough to make good communications impossible.

Maintenance and Adjustment The COBRA CB transceiver is specifically designed for the environment encoun- tered in mobile installations.
