Connecting a Speaker or Headphones
You can plug an amplified speaker or headphones
(not supplied) with Çinch (3.5 mm) mini-plug into the
HEADPHONE jack on the back of the scanner. This
automatically disconnects the internal speaker.
Note: Use an amplified speaker with this scanner.
Non-amplified speakers do not provide sufficient
volume for comfortable listening.
