Headphones and Speakers

You can plug headphones or speaker (neither included) into your scanner.

To use headphones, connect the plug into the headphone jack on the front panel. Headphones automatically mute the scanner’s speaker.

To use external speaker, connect the plug into the EXT SP jack on the rear panel.

Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

To protect your hearing, follow these earphone or headphones guidelines:

•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 listening. Turn on the scanner, and adjust the volume to a comfortable level.

•After 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.

•Do not wear headphones while driving. This can create a traffic hazard and is illegal in some areas.
