If your Cobra Marine Radio is not responding when you press a button, it might be because the Key Lock is activated. To solve this, simply press the Backlight/Key Lock button to deactivate the Key Lock feature.
Why is there no sound from my Cobra Marine Radio speaker?
If you're experiencing no sound from the speaker of your Cobra Marine Radio, the volume level might be too low, or the squelch level might be set too deep. Try re-adjusting both the volume and squelch settings to resolve this issue.
Why will my Cobra MR HH300 VP transmit at one watt, but not at five watts?
If your Cobra Marine Radio transmits at one watt but not at five watts, the batteries may be low. Replacing the batteries should solve this. Alternatively, the selected channel might be limited to one watt. Try switching to another channel.
What to do if my Cobra MR HH300 VP Marine Radio will not transmit?
If your Cobra Marine Radio will not transmit, it might be because the selected channel is limited to receive only. Try switching to another channel.
Why is there no answer to calls on my Cobra MR HH300 VP?
If you are not getting any answers to your calls on the Cobra Marine Radio, it could be that you are out of range of the other station. Try switching to five watts or moving closer. Also, the signal could be blocked by terrain. Move until you have a 'line-of-sight' to the other station.
How to fix no display on my Cobra MR HH300 VP Marine Radio LCD?
