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.
