Problem I'm getting all the hazard alerts, not just the ones for my area. I can't make Group DSC calls. Where can I find my radio's serial number? The radio won't let me enter my User MMSI. What do I do? Things to Try Check to make sure the FIPS codes in your radio were entered correctly (see Using FIPS codes for weather alerts on page 17). Sometimes the Weather Alert Watch may catch a hazard alert in the middle of the broadcast and miss which FIPS codes are affected. For your safety, the radio triggers the alert tone and switches to the weather channel when this happens. Make sure the Group MMSI was entered correctly. Look on the right side of the radio (the side with the microphone cord), behind the mounting bracket. Contact customer service. ENGINE NOISE SUPPRESSION Interference from the noise generated by the electrical systems of engines is sometimes a problem with radios. Your radio has been designed to be essentially impervious to ignition noise and alternator noise. However, in some installations it may be necessary to take measures to further reduce the effect of noise interference. Your radio's DC battery wires, antenna lead, and accessory cables should be routed away from the engine and engine compartment, and from power cabling carrying high currents. In severe cases of noise interference, it may be necessary to install a noise suppression kit. Contact the dealer where you purchased the radio for more information. 34
