Why does my Furuno Telephone transceiver blow a fuse when connected to the power supply?
The fuse might blow due to reversed power wires. Check the power cable for DC voltage and ensure the red wire connects to the positive (+) battery post, and the black wire connects to the negative (-) battery post. Also, check the fuse (6A 250V). If the fuse continues to blow after replacement, it is recommended to contact your dealer for advice.
What to do if "HI BATTERY" or "LO BATTERY" appears on my Furuno Telephone?
If you see a “HI BATTERY” or “LO BATTERY” message when you turn on your Furuno Telephone, it indicates that the power supply voltage is either too high or too low. Verify that the connected power supply voltage is not over 17 volts or lower than 10 volts.
What to do if my Furuno Telephone position is not displayed?
If your position is not displayed on your Furuno Telephone, check the accessory cable to ensure it's firmly fastened. Some GPS receivers use the battery ground line for NMEA connection. Also, verify the output signal format of the GPS receiver. This radio requires NMEA0183 format with GLL, RMB, or RMC sentence as an output signal. If the GPS receiver allows setting baud rate and parity, select “4800” and “NONE,” respectively.
What to do if the sound is not emitted from the internal or external speaker of my Furuno Telephone?
If no sound comes from the internal or external speaker of your Furuno Telephone, check if the accessory cable is firmly fastened. You can also short circuit the external speaker cable WHITE/ SHIELD.
How to fix popping or whining noise from the speaker of Furuno Telephone while engine runs?
If you hear popping or whining noises from the Furuno Telephone speaker while the engine is running, it's likely due to engine noise. Try rerouting the DC power cables away from the engine. You can also add a noise suppressor on the power cable or switch to resistive spark plug wires and/or add an alternator whine filter.
What to do if the sound is not emitted from the PA speaker of my Furuno Telephone?
If sound is not emitted from the PA speaker on your Furuno Telephone, make sure the accessory cable is firmly fastened. Short circuit the PA speaker cable RED/ SHIELD to test.
What to do if “PA ERROR” or “FOG ERROR” is shown on Furuno Telephone?
If “PA ERROR” or “FOG ERROR” appears when the PA/FOG mode is activated on your Furuno Telephone, verify that the accessory cable is firmly fastened. Short circuit the PA speaker cable RED/ SHIELD.
Why I cannot power on my Furuno Telephone?
If you cannot power on your Furuno Telephone, it may be due to no DC voltage reaching the transceiver or a blown fuse. Check the battery connections and the fuse. Also, ensure that the PWR switch is pressed and held to turn the radio on.
What to do if receiving station reports low TX power on my Furuno Telephone?
If a receiving station reports low TX power from your Furuno Telephone, even when the transceiver is set to HI power, have the antenna checked or test the transceiver with another antenna. If the problem persists, contact your dealer for advice.
Why can AM broadcasts be heard while in PA or Fog listen-back modes on my Furuno Telephone?
If you hear AM broadcasts while in PA or Fog listen-back modes on your Furuno Telephone, strong AM radio stations are likely being picked up by the speaker wires. Replace the speaker wires with a shielded 2-conductor wire.
