Traffic Safety
• Do not wear an earphone or headphones while you drive a vehicle or ride a bicycle. This
can create a traffic hazrd and can be illegal in some areas. 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
In a noisy area, an amplified extension speaker (not supplied) available at your local

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.
ABOUT YOUR SCANNER
Once you understand a few simple terms used in this manual and familiarize yourself with
your scanner’s features, you can put the scanner to work for you. You simply determine the

A frequency is the receiving signal location (expressed in kHz or MHz). To find active
frequencies, you can use the search function.
You can also search the One Touch Search Bands, which are preset groups of
frequencies categorized by type of service.
When you find a frequency, you can store it into a programmable memory location called a
channel, which is grouped with other channels in a channel-storage bank. You can then
scan the channel-storage banks to see if there is activity on the frequencies stored there.
Each time the scanner finds an active frequency, it stays on that channel until the
