FAQ

Why does my audio quality change after a few seconds on some HD Radio 

stations and on some other stations skip when I fi rst tune in?

HD Radio stations blend analog signals to digital HD Radio. The blend is typically 
smooth, but in some cases, the audio quality can take a few seconds to reach 
enhanced digital levels. This is not an issue with your HD Radio. This is an HD 
Radio broadcaster’s implementation issue, which the station should correct over 
time.

What can I do if I my audio is unclear or I don’t hear any audio?

If your radio audio is unclear or you don’t hear any audio, you may be 
experiencing one of the following conditions:

• 

Is the radio muted? If so, unmute the radio or turn up the volume.

• 

Is the radio in AUX mode? If so, your auxiliary device may not be sending 
audio signals or may not be correctly connected.

• 

Is anything plugged into the headphone jack? If so, unplug it.

• 

Check all connections, including power and antenna.

• 

Is the signal too weak? If so, tune to a stronger station or reposition your 
radio and/or antenna. 

• 

If you are using an antenna other than the one supplied, make sure the 
antenna supports FM reception. If the antenna uses an FM trap, make 
sure the FM trap is off.

Note:

  If you are using an amplifi ed antenna with adjustable gain, turn down 

the gain all the way and adjust slowly upward.
