Why Cobra MARINE HH500 has no sound from speaker?
If there's no sound coming from the speaker of your Cobra Marine Radio, it might be because the volume level is too low or the squelch level is set too high. Try readjusting both the volume and squelch settings to resolve this issue.
What to do if my Cobra Marine Radio will transmit at one (1) or three (3) watts, but not at six (6) watts?
If your Cobra Marine Radio transmits at lower power levels but not at six watts, the batteries may be low, so you should recharge or replace them. Alternatively, the selected channel might be limited to one watt, in which case you should switch to another channel.
What to do if Cobra Marine Radio has no display on LCD when radio is turned on?
If the LCD on your Cobra Marine Radio doesn't display anything when you turn it on, the batteries may be exhausted; try recharging or replacing them. Another possibility is that the batteries aren't installed correctly. Remove them and reinstall them, making sure to follow the polarity markings.
Why Cobra MARINE HH500 has no answer to calls?
If your Cobra Marine Radio gets no response to calls, you might be out of range of the other station. Try switching to three or six watts or moving closer. Also, the signal could be blocked by terrain, so move until you have a line of sight to the other station.
What to do if Cobra MARINE HH500 batteries run down quickly?
If the batteries in your Cobra Marine Radio are draining quickly, it's likely they are at the end of their life. Replace them with new batteries.
What to do if my Cobra MARINE HH500 will not transmit?
If your Cobra Marine Radio won't transmit, the selected channel might be receive-only. Try switching to another channel.
How to unlock Cobra MARINE HH500 if there is no response to button press?
If your Cobra Marine Radio isn't responding to button presses, the button lock might be activated. Press the Backlight/Key Lock button to deactivate it.
