    Why Onwa KV-290 Transceiver does not turn ON?

      Your Onwa Transceiver might not be turning on due to several reasons: * The power cable may not be correctly connected. Ensure the red (+) and black (-) cables are properly connected. * The power cable fuse could be broken. Find the cause of the blown fuse and replace it with a new 15A fuse. * The operating voltage might be outside the acceptable range (more than 17V or less than 9V). Adjust the power supply to 13.8V.

The volume could be too low. Rotate the [VOL] knob to increase the volume. 3. Water penetration in the speaker grill might be the issue. Activate the Vibration function to help drain the water.
