antenna or outdoor base station antenna.
Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to
connect an outdoor antenna. If the antenna is over 15 m from
the scanner, use RG-213/U or "air cell" type low loss coaxial
cable. You can get a BNC adapter at your local electronics
store.

Connecting an Earphone/ ext. Speaker

For private listening, you can plug a 3.5 mm mini plug earphone
or mono or stereo headphones (not supplied) into the
headphone jack on top of your scanner. This automatically
disconnects the internal speaker.

Connecting an Extension Speaker

In a noisy area, an optional extension speaker, positioned in the
right place, might provide more comfortable listening. Plug the
speaker cable's 3.5- mm mini-plug into your scanner's jack. For
larger audio power, active speakers (like used for PC's) are
recommended.
WARNING!
If you connect an external speaker to the scanner's headphone
jack, never connect one of the audio output wires to a power
supply and /or ground. This might damage the scanner.

About Your Scanner

We use a few simple terms in this manual to explain the features
of the scanner. Familiarize yourself with these terms and the
scanner's features, and you can put the scanner to work for you
right away. Simply determine the type of communications you
want to receive, then set the scanner to scan those
communications.
A frequency, expressed in kHz or MHz, is the tuning location of a
station. To find active frequencies, you use the search function
or refer to a frequency reference.
Besides searching within factory pre-programmed frequency
ranges, you can also program Your own frequency ranges and
search there. The factory pre-programmed ranges are preset to
groups of commonly used frequencies depending on the type of
services.
When you search and find a desired frequency, you can store it
into a programmable memory location called a channel.
