User's Manual

Wearing headphones while operating a motor vehicle or riding a bicycle is very dangerous
and illegal. Do not operate any vehicle while listening to iSCAN with headphones or
earphones.
Connecting an Optional External Antenna
The BNC antenna connector on iSCAN makes it easy to use the scanner with a variety of
antennas, such as an external mobile antenna or outdoor base station antenna.
Always use 50-ohm coaxial cable, such as RG-58 or RG-8 low-loss dielectric coaxial cable.
If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter.
Follow the installation instructions supplied with the antenna, route the antenna cable to the
scanner, then connect it to the antenna jack.
WARNING: Use extreme caution when installing or removing an outdoor antenna. If the
antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches
a power line, touching the antenna, mast, cable, or guy wires can cause electrocution and
death. Call the power company to remove the antenna. DO NOT attempt to do so yourself.
Connecting an Earphone or Headphones
For private listening, you can plug an 1/8-inch (3.5 mm) mini-plug earphone or headphones
(not supplied) in the HEADPHONE jack on top of iSCAN. This automatically disconnects
the internal speaker.
Connecting an External Speaker
In a noisy area, an amplified speaker (not supplied) might provide more comfortable
listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini-plug into iSCAN’s HEADPHONE
jack.
Using AC Power
You can power the scanner using an optional AC USB power adaptor (RadioShack Catalog
Number 273-114) and the supplied USB power/data cable.
