PRO-51 200-Channel Direct Entry Programmable Scanner
(200-0308A) Preparation Faxback Doc. # 39013
Power Sources
You can power your scanner from any of three sources:
Internal battery power
Standard AC power (using an optional AC adapter)
Your vehicle's battery power (using an optional DC adapter)
See "Using Other Power Sources" on Faxback Doc. # 39016, to use AC or
vehicle battery power, and for information about using and recharging
nickel cadmium batteries.
Using Batteries
You can operate your scanner from four AA batteries. For longest operation
and best performance, we recommend alkaline batteries (Radio Shack Cat. No.
23-552). Or you can use rechargeable nickel-cadmium batteries (Cat. No. 23-
125).
WARNING: The scanner has a built-in circuit that lets you recharge nickel-
cadmium batteries inside the battery compartment. However, you
must never use this circuit when you have installed non-recharge-
able batteries in the scanner. Be sure to read "Important Infor-
mation about the External Power Jacks" and "Charging Nickel-
Cadmium Batteries" on Faxback Doc. # 39016.
To install batteries in your scanner, follow these steps.
1. Press open the battery compartment cover on the bottom.
2. Remove any old batteries from the compartment and cover.
3. Install two batteries in the compartment and two in the cover as indi-
cated by the polarity symbols (+ and -) marked inside the compartment
and inside the cover.
4. Replace the cover.
Your scanner beeps every 15 seconds when the batteries are low. When this
happens, immediately replace or recharge all four batteries.
Connecting The Antenna
Follow these steps to attach the supplied flexible antenna to the connector
on the top of your scanner.
1. Slip the slot in the antenna's connector over the protrusion on the
jack.
2. Press down and rotate the antenna's base clockwise until it locks into
place.
Connecting an Optional Antenna
The antenna connector on your scanner makes it easy to use your scanner with
a variety of antennas. You can remove the supplied antenna, if you want, and
attach a different one, such as an external mobile antenna or outdoor base
antenna. Your local Radio Shack store sells a variety of antennas.
Use coaxial cable to connect an outdoor antenna. Always use 50-Ohm coaxial
cable, such as RG-58 or RG-8. For lengths over 50 feet, use RG-8 low-loss
dielectric coaxial cable. You will also need a BNC connector (Cat. No. 278-
103 or 278-185) to connect an optional antenna.
WARNING: When installing or removing an outdoor antenna, use extreme
caution. 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 an Earphone/Headphone
For private listening, plug an earphone into the headphone jack on top of
your scanner. This automatically disconnects the speaker. We recommend
Radio Shack's earphone (Cat. No. 33-175) or mono headset (Cat. No. 20-210).
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone/
headphone:
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 you begin listening. After
you begin listening, adjust the volume to a comfortable level.
Once you set the 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.
Traffic Safety
Do not wear headphones or an earphone while you drive a vehicle or ride a bicycle. This can create a traffic hazard and is illegal in some areas.
Even though some headphones and earphones are designed to let you hear some
outside sounds when you listen at normal levels, they still present a
traffic hazard.
Connecting an Extension Speaker
In a noisy area, an extension speaker, such as Radio Shack Cat. No. 21-549,
positioned in the right place, might provide more comfortable listening.
Plug the speaker cable's 1/8 inch mini-plug into the scanner's headphone
jack.
NOTE: Connecting an extension speaker disconnects the scanner's built-in
speaker.
Resetting The Scanner
If the scanner's display locks up or does not work properly after you
connect a power source, you might have to reset the scanner.
CAUTION: This procedure clears all the information you have programmed into
the scanner. Use this procedure only when you are sure your
scanner is not working properly.
1. Turn off the scanner.
2. While you press and hold down the 2 and 9 keys, turn on the scanner.
Using The Belt Clip
You can use the supplied belt clip to make the scanner easier to use when
you are on the go. Use the two supplied screws to attach the belt clip to
the scanner. Then slide the belt clip over your belt or waistband.
