• 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. 

 

Traffic Safety 

 

Do not wear an earphone or headphones with your scanner when operating a motor vehicle 

or riding a bicycle 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 while riding a bicycle, be very 

careful. Do not listen to a continuous broadcast. Even though some earphones and 

headphones let you hear some outside sounds when you listen at normal levels, they still 

can present a traffic hazard. 

 

CONNECTING AN EXTENSION SPEAKER

comfortable listening. Plug the speaker cable’s 1/8 inch (3.5 mm) mini-plug into your 

scanner’s (headphone symbol mark) jack. 

 

Note: You must use an amplified speaker with this scanner. Non-amplified speakers do not 

provide sufficient volume for comfortable listening. 

 

USING THE BELT CLIP 

 

You can use the belt clip attached to the back of the scanner for hands-free carrying when 

you are on the go. Slide the belt clip over your belt or waistband.

type of communications you want to receive, then set the scanner to scan them. 

 

A frequency is the receiving signal location (expressed in kHz or MHz). To find active
