PRO-2044 Programmable 80 Channel Home Scanner 200-0416 Preparation

PRO-2044 Programmable 80-Channel Home Scanner
(200-0416) Preparation Faxback Doc. # 38283

This scanner is primarily designed for use in the home as a base station.
You can place it on a desk, shelf, or table.

Your scanner's front feet fold up or down. Adjust them to give you the best
view of the display.

Connecting an Antenna

Connecting the Supplied Antenna

You must install an antenna before you can operate the scanner.

The supplied telescoping antenna helps your scanner receive strong local
signals. To install the antenna, screw it clockwise into the hole on the
scanner's top.

The scanner's sensitivity depends on the antenna's length and various
environmental conditions. For the best reception of the transmissions you
want to hear, adjust the antenna's length.

Connecting an Outdoor Antenna

Instead of the supplied antenna, you can connect an outdoor base-station or
mobile antenna (not supplied) to your scanner. Your local Radio Shack store
sells a variety of antennas. Choose the one that best meets your needs.

When deciding on a mobile or base-station antenna and its location, con-
sider these points:

The antenna should be as high as possible on a vehicle or the house.

The antenna and its cable should be as far as possible from sources of
electrical noise (appliances, other radios, etc.).

The antenna should be vertical for the best performance.

To connect an optional base-station or mobile antenna, first remove the
supplied antenna from the scanner. Always use 50-Ohm coaxial cable, such as
RG-58 or RG-8, to connect the base-station or mobile antenna. For lengths
over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna
cable's connector does not fit in the ANT. Jack, you might also need a
Motorola-to-BNC antenna plug adapter, such as Radio Shack Cat. No. 278-117.
Your local Radio Shack store carries a wide variety of coaxial antenna cable
and connectors.

Once you choose an antenna, follow the mounting instructions supplied with
the antenna. Then route the antenna's cable to the scanner and connect the
cable to the ANT. Jack on the back of the scanner.

CAUTIONS: Do not run the cable over sharp edges or moving parts that might
damage it.

Do not run the cable next to power cables or other antenna
cables.

WARNING: Use extreme caution when you install or remove an out-door an
tenna. If the antenna starts to fall, let it go! It could contact
overhead power lines. If the antenna touches a power line, contact
with 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 Power

Using AC Power

The scanner's supplied AC adapter lets you power the scanner from a standard
AC outlet. To connect power to the scanner, insert the AC adapter's barrel
plug into the DC 12 V jack on the back of the scanner, then plug the AC
adapter into a standard AC outlet.

WARNING: Do not use the AC adapter's polarized plug with an extension cord
receptacle unless the blades can be fully inserted to prevent
blade exposure.

CAUTIONS: Be sure to connect the AC adapter to the scanner before you
connect it to an AC outlet, and disconnect the AC adapter from
the AC outlet before you disconnect it from the scanner.

The supplied AC adapter supplies 12 bolts DC power and delivers
500 milliamps. Its center tip is set to positive, and its plug
properly fits the scanner's DC 12V jack. Using an adapter that
does not meet these specifications could damage the scanner or
the adapter.

Using Your Vehicle's Battery

If your AC power does not work in an emergency, you can power your scanner
from your vehicle's cigarette lighter socket with an optional DC cigarette
lighter power cable, such as Cat. No. 270-15633 (not supplied).

To connect an optional DC cigarette lighter power cable, insert its barrel
plug into the DC 12V jack on the back of the scanner, then plug the power
cable into your vehicle's cigarette lighter socket.

CAUTIONS: If you use a DC cigarette lighter power cable with the scanner,
it must supply 12 bolts and deliver at least 500 milliamps. Its
center tip must be set to positive, and its plug must correctly
fit the DC 12V jack on the back of the scanner. The recommended
power cable meets these specifications. Using a power cable that
does not meet these specifications could seriously damage the
scanner or the power cable.

If you use a cigarette lighter power cable and your vehicle's engine is
running, you might hear electrical noise from the engine while scanning.
This is normal.

NOTE: Mobile use of this scanner is unlawful or requires a permit in some
areas. Check the laws in your area.

Connecting an External Speaker

You can connect an optional amplified external speaker with a 1/8 inch plug
(such as Cat. No. 21-541) to the scanner.

Insert the speaker's plug into the (symbol) jack on the front of the
scanner.

NOTE: Plugging in an external speaker disconnects the scanner's internal
speaker.

Connecting an Earphone/Headphones

You can connect an optional earphone (such as Cat. No. 33-175) or a pair of
monaural headphones (such as Cat. No. 20-210) with a 1/8-inch plug to the
scanner.

Insert the earphone's or headphones' plug into the (symbol) jack on the
front of the scanner.

NOTE: Plugging in an earphone or headphones disconnects the scanner's
internal speaker.

Listening Safely

To protect your hearing, follow these guidelines when you use an earphone
or headphones.

Set VOLUME to the lowest setting before you begin listening. After you put
on the earphone or headphones, adjust VOLUME to a comfortable level.

Do not listen at extremely high volume levels. Extended high-volume listen-ing can lead to permanent hearing loss.

Once you set 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.
