Introduction
Many organizations, such as police
and fire departments, emergency
response teams, and airports, use
radio communication extensively
every day. Scanning these radio
communications is a great way
to listen to all the exciting events
happening in your area.
Radio communication is also used
to coordinate large events, and
spectators with radio scanners
listen to behind-the-scenes action.
One obstacle to scanning can be
configuring your scanner. The
iScan is designed to simplify this
process and get you started as
quickly and easily as possible.

Setting Bandplan and Clock
To turn on your iScan, press the Power button.
When you turn on your iScan for the first time, use the four-
direction pad and SEL to set your bandplan, date, and time.
Antenna
Your iScan's durable antenna provides
excellent reception. Align its connector
with the iScan antenna post tabs, press
down and turn.
To connect a larger antenna, use a coax-
to-BNC adapter and 50-ohm coaxial cable
(RG-58, RG-8).*
Disconnect any outdoor antenna during
electrical storms to prevent damage.
External Power
Before starting, make sure the scanner is off.
Use the supplied shielded USB cable.
Some USB power adapters can interfere with
the scanner's reception. Using an incompatible
USB cable may damage your scanner.
Batteries
Always set the Battery Type:
• ALK − Alkaline
• NI-MH − Rechargeable, Nickel-
Metal Hydride
Warning:Never install alkaline batteries with the Battery
Type switch set to NI-MH. Alkaline batteries can get hot or
explode if you try to recharge them.
• Use only fresh batteries of the required size and type.
Do not mix old and new batteries, different battery
types (alkaline or rechargeable), or rechargeable
batteries of different capacities.
• Dispose of batteries promptly and properly; do not burn
or bury them.
• For storage of a month or longer, remove the batteries.
Batteries can leak chemicals that can damage
electronic parts.
RecycleRechargeableBatteries
Recycle your old rechargeable batteries at one of the
many collection sites in the U.S. and Canada. To find the
site nearest you, visit www.call2recycle.org or call toll-free
1-877-2-RECYCLE.
*To protect your hearing:
• Set the volume to zero before putting on headphones. With the
headphones on, adjust the volume to a comfortable level.
• Avoid increasing volume. Over time, your sensitivity decreases, so volume
levels that do not cause discomfort might damage your hearing.
• Avoid or limit listening at high-volume levels. Prolonged exposure to high-
volume levels can cause permanent hearing loss.
Wearing headphones while operating a motor vehicle or riding a bicycle
can create a traffic hazard and is illegal in most areas. Even though some
headphones let you hear some outside sounds when listening at normal volume
levels, they still can present a traffic hazard. Exercise extreme caution!

information about the transmission source.
Scanning Legally
Your scanner covers frequencies used by many different groups including
police and fire departments, ambulance services, government agencies,
private companies, amateur radio services, military operations, pager services,
and wireline (telephone and telegraph) service providers. It is legal to listen to
almost every transmission your scanner can receive. However, there are some
transmissions you should never intentionally listen to. These include:
• Telephone conversations (cellular, cordless, or other means of private
telephone signal transmission)
• Paging transmissions
• Any intentionally decoded scrambled or encrypted transmissions
According to the Electronic Communications Privacy Act (ECPA), you are
subject to fines and possible imprisonment for intentionally listening to, using,
or divulging the contents of such a transmission unless you have the consent
of a party to the communication (unless such activity is otherwise illegal). This
scanner has been designed to prevent reception of illegal transmissions. This
is done to comply with the legal requirement that scanners be manufactured
so as to not be easily modifiable to pick up those transmissions.
Do not open your scanner’s case to make any modifications that could
allow it to pick up transmissions that are illegal to monitor. Doing so could
subject you to legal penalties. We encourage responsible, legal scanner use.
In some areas, mobile use of this scanner is unlawful or requires a permit.
Check the laws in your area. It is also illegal in many areas to interfere with
the duties of public safety officials by traveling to the scene of an incident
without authorization.
Warning: Changes or modifications to this unit not expressly approved
by the party responsible for compliance could void the user’s authority to
operate the equipment.
Shielded cables must be used with this unit to ensure compliance with the
Class B FCC limits.

Maintenance
Modifying or tampering with the scanner’s internal
components can cause a malfunction and might invalidate
its warranty and void your FCC authorization to operate it.
• Handle the scanner carefully; do not drop it.
• Keep the scanner dry; if it gets wet, wipe it dry
immediately.
• Use and store the scanner only in normal temperature
environments.
• Keep the scanner free from dust and dirt, and wipe it
with a damp cloth occasionally to keep it looking new.
Birdie Frequencies
Birdies are internal operating frequencies that can cause
interference. All scanners have birdies, but if the interference is
not severe, adjusting the squelch might avoid the birdie, but if
you program one of these frequencies during a search, you will
hear only noise on that frequency.
If you suspect that a programmed frequency is being affected
by a birdie, try removing the antenna. If the noise stops, it is
most likely coming from an external source, and moving the
scanner may reduce the noise or solve the issue. If the noise
on a frequency continues when you remove the antenna, it is
almost certainly the result of a birdie.
Updating the Software Database
RadioReference frequently updates their databases, which
you can use to upload your local database.
Note: Updating the RadioReference database requires an
Internet connection.
Toupdateyourdatabase:
1. Open the iScan software on your PC.
