The Basics

Listening Safely

To protect your hearing, follow these guidelines:

•  Do not connect an earphone or headphones to the 

scanner. The warning alert volume is not adjustable, and 
damage to your hearing might result if a warning alert 
sounds while an earphone or headphones is connected.

•  Do not listen at extremely high volume levels. Extended 

high-volume listening can lead to permanent hearing loss.

•  Set the volume to the lowest setting before you begin 

listening. After you begin listening, adjust the volume to a 
comfortable level.

•  Once you set the volume, do not increase it. Over time, 

your ears adapt to the volume level, so a volume level 
that does not cause discomfort might still damage your 
hearing.
