MINOR TROUBLESHOOTING Your IC M80 has been design engineered to provide years of trouble free operation This has been made possible through the use of the most current technology along with ICOM s years of experience in the production of high quality depend able VHF FM equipment Your IC M80 has been specifically designed to withstand years of use in many different extreme environments However as with all marine electronic equipment it is possible that some problems may occur that would interfere with the operation of the set Should such a problem occur it is recommended that your unit be taken directly to your ICOM dealer or authorized ICOM repair service center for qualified service Some problems may occur which may interfere with the operation of the radio that are not directly related to the electronic circuitry within your set Below is a brief descrip tion of common problems outside of your set that may occur and means of identifying them 1 Antenna If it appears that you are having unusual difficulty in trans mitting or receiving properly it is possible that the cause is due to a defective or faulty antenna system The most common problem that occurs with antenna systems include broken or shorted antenna cable runs or corroded or defective connector installation Double check to be sure the connector is soldered to the connector and that it is not shorted Visually inspect these items to help isolate the problem A qualified technician should correct the antenna problem 2 Power loss If in turning your radio to the ON position the display fails to light and no sound is heard from the radio a common problem is low or no power from the battery source in the boat Visually inspect the power cable from the battery for broken or short leads Also inspect the fuses both in the vessel s fuse block as well as the fuse in the power cable on the radio for corrosion or a blown fuse 3 Microphone cable If in transmitting either the voice is not heard or the TX letters is not displayed the problem could be in the micro phone cables Inspect the mic cables for possible breaks or tears that could be the source of the problem If such is the case replace the mic cord 4 Ignition noise Occasionally ignition noise from operation of the vessel s engine and or occasionally refrigeration or power generating equipment may cause static interference with your radio Ignition noise alternator whine and spurious signals from other electrical devices may be found and cured by experi enced technicians using known techniques and noise reduction devices 19
