Why Onwa KV-290 Transceiver does not turn ON?
- M

  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.

  If you're not getting any sound from your Onwa Transceiver speaker, consider the following: 1. The squelch level might be too high. Try rotating the [SQL] knob to adjust the squelch level. 2. 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.
