If your TQ Marine Radio KTX2 shows no sign of power or the screen is blank, here's what to check: 1. Make sure the KTX2 breaker is closed. Check and reset the circuit breaker. 2. Confirm that power and ground are correctly supplied to the KTX2. 3. If the issue persists after checking the breaker and power supply, replacement of the KTX2 may be required.
What to do if the 'BAT LOW' message appears on my TQ Marine Radio KTX2?
If the 'BAT LOW' message appears on the center of the screen of your TQ Marine Radio KTX2, it means the voltage is below 11 VDC. Here’s what you should do: 1. If the engine is running, increase the RPM. 2. If the engine is off, recharge or replace the battery. The KTX2 is designed to operate above 9 VDC, so determine the cause of the low voltage before the next use.
Why does my TQ Marine Radio KTX2 say 'Do System Restart'?
The 'Do System Restart' message on your TQ Marine Radio KTX2 indicates that an error has been detected and the unit should be restarted. To resolve this: 1. Switch the unit off, wait 5 seconds, and then switch it back on. 2. If the error repeats after the restart, further assistance is needed.
What to do if there is no transmission output from my TQ Marine Radio KTX2?
If your TQ Marine Radio KTX2 is not transmitting, indicating a severe failure, follow these steps: 1. Check all connections to ensure they are properly secured. 2. If checking the connections doesn't resolve the issue, further assistance is needed.
What does 'ANT' on the screen of my TQ Marine Radio KTX2 mean?
If 'ANT' appears on the right side of the screen of your TQ Marine Radio KTX2, it indicates a possible L-Band antenna failure. Check the antenna installation, including the cable and connector, and resolve any issues before the next use.
What does 'TRX' on the screen of my TQ Marine Radio KTX2 mean?
If 'TRX' appears on the right side of the screen of your TQ Marine Radio KTX2, it indicates a weak transmitter with limited output power. Check the antenna installation, including the cable and connector. If the problem persists, further assistance is needed.
What causes a 'CRC Failure' on the GNSS Data Page of my TQ Marine Radio KTX2?
A 'CRC Failure' on the GNSS Data Page of your TQ Marine Radio KTX2 is caused by insufficient data from the GPS source. To address this: 1. Ensure that a minimum of 3 GPS satellites are in view. 2. Check the GPS antenna connection. 3. If the problem continues, the GPS source may have failed.
What causes an 'Intern. Comm. Fail' error on my TQ Marine Radio KTX2?
An 'Intern. Comm. Fail' error on your TQ Marine Radio KTX2 indicates a severe internal communications error. To resolve this: 1. Attempt to restart the unit. 2. If the error persists after restarting, further assistance is needed.
What does 'Err FPGA' mean on my TQ Marine Radio KTX2?
The 'Err FPGA' message on your TQ Marine Radio KTX2 indicates a severe error where there is no access to the FPGA. To attempt to resolve this: 1. Restart the unit. 2. If the error persists after restarting, further assistance is needed.
