CONNECTING POWER
Using Standard AC Power
It is possible to power the scanner from a standard AC outlet using the
supplies AC adapter.
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: The supplied AC adapter supplies 12 volts and delivers 500
milliamps. Its center tip is set to positive, and its plug
properly fits the scanner's DC 12V jack. Using an AC adapter
that does not meet these specifications could damage the scanner
or the adapter. The scanner's display dims and the scanner
sounds a tone every 15 - 30 seconds if the AC adapter used does
not provide the required 12 volts DC.
Be sure to connect the AC adapter to the scanner before
connecting it to a standard AC outlet. Then disconnect the
adapter from the AC outlet before disconnecting it from the
scanner.
If there is difficulty inserting the AC adapter's polarized
plug, do not force it. Turn it over and reinsert it.
1. Insert the supplied AC adapter's barrel plug into the scanner's DC
12V jack.
2. Plug the adapter's power module into a standard AC outlet.
Memory Backup
If a power failure occurs or if the power cord is disconnected, the
scanner's memory backup circuit keeps information in memory for up to 3
days.
NOTE: The memory backup circuit begins to protect the contents in
memory within a few minutes after the scanner is plugged in.
Using Vehicle Battery Power
To power the scanner from a vehicle's battery power, a DC adapter (such as
a Radio Shack Cat.No.270-1562) is required.
CAUTIONS: The vehicle must have a 12-volt DC, negative-ground electrical
system.
The recommended DC adapter supplies 12 volts and delivers at
least 500 milliamps. Its center tip must be set to positive,
and its plug properly fits the scanner's DC 12V jack. Using a
DC adapter that does not meet these specifications could damage
the scanner or the adapter. The scanner's display dims and the
scanner sounds a tone every 15 -30 seconds if the DC adapter
used does not provide the required 12 volts DC.
Be sure to connect the DC adapter to the scanner before
connecting it to the vehicle's cigarette-lighter plug. Then
disconnect the adapter from the vehicle's cigarette-lighter plug
before disconnecting it from the scanner.
Follow these steps to use vehicle battery power:
1. Set the adapter's voltage switch to 12V.
2. Connect the Adaptaplug's blue barrel, right-angle plug to the adapter's
cable with the tip set to + (positive).
3. Insert the barrel plug into the scanner's DC 12V jack.
4. Plug the other end of the adapter into the vehicle's cigarette-lighter
socket.
NOTE: If the scanner does not operate properly when using a DC adapter,
unplug the adapter from the lighter socket and clean the socket to
remove ashes and other debris.
CONNECTING AN ANTENNA
Either the supplied telescoping antenna or an optional antenna can be
connected.
Telescoping Antenna
To attach the telescoping antenna, simply screw it into the hole on top of
the scanner.
The antenna's length controls its sensitivity. Adjust the length of the
telescoping antenna as follows for best reception.
29 - 54 MHz Extend all 3 segments
108 - 174 MHz Extend only 2 segments
406 - 956 MHz Collapse Fully (only 1 segment extended)
Optional Outdoor Antenna
The supplied antenna is usually adequate for strong, local signals.
However, for the best results in receiving weaker, more distant signals on
all bands, attach an optional outdoor antenna (not supplied), such as a
mobile, telescoping, multi-band, or outdoor base antenna.
WARNING: When installing or removing an outdoor antenna, follow all
cautions and warnings included with the antenna.
NOTES: This scanner uses a BNC antenna connector. If the coaxial cable's
connector does not fit the ANT jack, an adapter might also be
needed. Local Radio Shack stores sell a complete line of outdoor
antennas, adapters, BNC connectors, and mounting hardware.
Always use 50-Ohm coaxial cable to connect an outdoor antenna. For
lengths under 50 feet, use RG58 (Cat.No. 278-1314) or RG8/M
(Cat.No.278-1313). For lengths over 50 feet, use RG-8, low-loss
coaxial cable (Cat.No.278-1312).
For the best performance, consider the following when deciding on an
outdoor base antenna and its location:
The location of the external antenna should be as high as possible.
The external antenna and antenna cable should be as far away as
possible from sources of electrical noise (appliances, other radios,
and so on).
The external antenna should be vertical.
Mount the antenna following the instructions supplied with the antenna and
its mounting hardware, then follow these steps to connect an external
antenna.
1. Route the antenna cable to the scanner and connect it to the ANT jack
on the back of the scanner.
CAUTION: Do not route the cable over sharp edges or moving objects.
2. Remove the supplied antenna from the top of the scanner.
RESETTING THE SCANNER'S DISPLAY
If the scanner's display locks up after connecting a power source, follow
these steps to reset it.
1. If the scanner is off, press POWER to turn it on.
2. Using a pointed object, such as a straightened paper clip, press RESET
on the back of the scanner. The display resets, and the scanner turns
off.
3. Press POWER to turn on the scanner again.
INITIALIZING THE SCANNER
If the scanner or its display does not work properly even after resetting
it, follow these steps to initialize the scanner.
CAUTION: Initializing the scanner clears all the channels stored in
memory. Initialize the scanner only when it is certain the unit
is not working properly.
1. If the scanner is off, press POWER to turn it on.
2. Press and hold ./CLEAR, then press RESET on the back of the scanner
using a pointed object, such as a straightened paper clip. The display
resets, and the scanner turns off.
3. Press POWER to turn on the scanner.
CONNECTING AN EARPHONE/HEADPHONES/EXTERNAL SPEAKER
The 1/8-inch EXT SP jack on the back of the scanner provides for connection
of an earphone, headphones, or an external speaker.
For private listening, connect an earphone (Cat.No.33-175).
For more comfortable private listening, connect monaural headphones
(Cat.No.20-210).
For listening from a remote area or in a noisy area, connect an
extension speaker (Cat.No.21-549).
NOTE: Connecting any external device to the EXT SP jack automatically
disconnects the internal speaker.
Listening Safely
To protect hearing, follow these guidelines when using an earphone or
headphones.
Do not listen at extremely high volume levels. Extended high-volume
listening can lead to permanent hearing loss.
Set the volume to the lowest setting before beginning to listen.
After listening is begun, adjust the volume to a comfortable level.
Once the volume is set, do not increase it. Over time, human ears
adapt to the volume level, so a volume level that does not cause
discomfort might still damage a user's hearing.
Traffic Safety
Do not wear an earphone or headphones while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and is illegal in some
areas.
Even though some earphones are designed to let outside sounds in when
listening at normal volume levels, they still present a traffic hazard.

UNDERSTANDING THE SCANNER'S MEMORY
Up to 110 frequencies can be stored in the scanner's memory. Each
frequency is stored into either a memory called a channel, or a temporary
memory called a monitor. This scanner has 100 channel memories and 10
monitor memories.
Channel-Storage Banks
To make it easier to identify and select the channels a user wants to
listen to, channels are divided into 10 channel-storage banks of 10
channel search. Use each channel-storage bank to group frequencies, such
as the police department, fire department, ambulance services, or aircraft.
For example, the police department might use four frequencies, one for each
side of town. Police frequencies could be programmed starting with Channel
1 (the first channel in Bank 1) and the fire department could be programmed
starting with Channel 11 (the first channel in Bank 2).
Monitor Memories
The scanner has 10 monitor memories. These memories can be used to
temporarily store frequencies while deciding whether or not to store them
into channels. This is handy for quickly storing an active frequency when
searching through an entire band. These memories can be manually selected,
but they cannot be scanned. See "Searching For and Temporarily Storing
Active Frequencies".
When in the monitor mode, one of the memory numbers (1 - 10) appears to the
right of the MON indicator. The number indicates the current monitor
memory.
