and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.
To help avoid hearing loss or damage:
D
Adjust the volume control to the lowest setting.
D
Increase volume slowly until you hear comfortably
and clearly.
