•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 discom- fort might still damage your hearing.

traffic safety

Do not use an earphone or headphones with your scanner when operating a motor vehicle in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas.

If you use an earphone or headphones with your scanner, be very careful. Do not listen to a continuous broadcast. Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

connecting an extension speaker

In a noisy area, an optional extension speaker, posi- tioned in the right place, might provide more com- fortable listening. Plug the speaker cable's 1/8-inch (3.5-mm) mini-plug into your scanner's headphone jack. Your local RadioShack store carries a selection of suitable speakers.

Warning: If you connect an external speaker to the scanner's headphone jack, never connect the audio output line to a power supply and ground. This might damage the scanner.
