Headphones And Speakers; Keytones And Brightness - Radio Shack 20-163 User Manual

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.

Keytones and Brightness

Your scanner features a backlit keypad and display for easy viewing
and sounds a tone each time you press a key.
