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.
