INTRODUCTION
Your new PSR-216 Programmable Scanner lets you in on all
the action! This scanner gives you direct access to over
35,000 frequencies. You can store frequencies in your
scanner's 200 channels, and you can change your selec-
tions at any time.
It incorporates a custom-designed microprocessor — a tiny,
built-in computer which gives your scanner these special
features:
Ten Preprogrammed Search Bands – let you search for
transmissions within preset frequency ranges, so you can
find interesting frequencies more quickly.
Ten Channel-Storage Banks – lets you group your stored
frequencies so you can easily identify calls.
Duplicate Frequency Check – automatically warns you if
you try to store a frequency you’ve already stored, to help
you use the scanner’s memory more efficiently.
Liquid Crystal Display – shows the selected channel and
frequency.
Two Second Scan Delay – helps prevent the loss of replies
on a channel while you are scanning.
Memory Backup – keeps the channel frequencies stored in
your scanner's memory for up to 1 hour without the battery.
Lockout Function – makes your scanner skip over speci-
fied channels.
Priority Channel – helps keep you from missing important
calls on the selected priority channel.
Monitor Memories – let you save up to 20 channels located
during a frequency search.
Flexible Antenna with BNC Connector – provides excel-
lent reception. The BNC connector makes it easy to attach
and remove the antenna or a variety of optional antennas.
Your PSR-216 covers the following bands:
68–88 MHz
108–174 MHz
380–512 MHz
806–960 MHz

PREPARATION
POWER SOURCES
You can power your scanner from any of four sources:
•Internal batteries (not supplied) with the provided battery
holder
•A rechargeable scanner battery pack (not supplied)
•Standard AC power (using an optional AC adapter)
•Vehicle battery power (using an optional DC cigarette-
lighter adapter)
You can power your scanner from six AA batteries. For the
longest operation and best performance, we recommend
alkaline batteries. You can also power the scanner using a
rechargeable scanner battery pack or rechargeable nickel-
cadmium batteries, and recharge it as you use the scanner.
Caution: Do not mix old and new batteries, different types of
batteries (standard, alkaline, or rechargeable), or recharge-
able batteries of different capacities.
Notes:
•The POWER jack lets you connect an external AC or DC
adapter to operate the scanner. Connecting an adapter
to POWER disconnects the internal batteries. You can use
the POWER jack with either non-rechargeable or recharge-
able nickel-cadmium batteries installed.
•The CHARGE jack lets you connect an external AC or DC
adapter to operate the scanner. The internal batteries re-
main connected when you connect an adapter to
CHARGE, and get recharged when you connect a charger.
Warning: Never use the CHARGE jack with non-recharge-
able batteries! If you try to recharge non-rechargeable bat-
teries, they could get very hot and explode.
Battery Install
1. Press down on the battery compartment cover on the bot-
tom of the scanner and slide the cover in the direction of
the arrow to remove it.
2. Slide the battery holder out of the battery compartment.
3. If you are installing individual batteries, insert six AA bat-
teries in the battery holder as indicated by the polarity
PSR216OM.p65 2004/04/08, 16:49Page 4 AdobePageMaker6.5J/Win

5
symbols (+ and –) marked on the battery holder.
4. Slide the battery holder or battery pack into the compart-
ment.
Caution: The battery holder or battery pack fits only one
way inside the battery compartment. Do not force it.
5. Replace the cover.
When battery power is low, BATT flashes and the scanner
beeps about every 3 seconds. Immediately replace all six
non-rechargeable batteries or recharge the rechargeable
batteries or battery pack.
Caution: Always dispose of old batteries promptly and prop-
erly. Do not bury or burn them.
Using Standard AC Power
To power the scanner from AC power, you need an AC
adapter.
Cautions:
•You must use an AC adapter that supplies 9 volts and
delivers at least 300 milliamps. Its center tip must be set
to negative, and its barrel plug must correctly fit the
scanner's POWER/CHARGE jack. The recommended
adapter meets these specifications. Using an adapter that
does not meet these specifications could damage the
scanner or the adapter.
•When you finish using the AC adapter, disconnect it from
the AC outlet first. Then disconnect it from the scanner.
Plug the adapter's barrel plug into the scanner's POWER
jack. Then plug the adapter's power module into a standard
AC outlet.
Using Vehicle Battery Power
To power the scanner from your vehicle's cigarette-lighter
socket, you need a DC adapter.
Cautions:
•You must use a DC adapter that supplies 9 volts and de-
livers at least 300 milliamps. Its center tip must be set to
negative, and its plug must correctly fit the scanner's
POWER/CHARGE jack. The recommended adapter
meets these specifications. Using an adapter that does
not meet these specifications could damage the scanner
or the adapter.
PSR216OM.p65 2004/04/08, 16:49Page 5 AdobePageMaker6.5J/Win

6
•To protect your vehicle's electrical system, always plug
the adapter into the scanner before you plug it into your
vehicle's cigarette-lighter socket. Always unplug the
adapter from the vehicle's cigarette-lighter socket before
you unplug it from the scanner.
Plug the adapter's barrel plug into the scanner's POWER
jack. Then plug the adapter's power module into your vehicle's
cigarette-lighter socket.
Charging a Rechargeable Battery Pack/
Rechargeable Batteries
Your scanner has a built-in charging circuit that lets you
charge a rechargeable battery pack or rechargeable nickel-
cadmium batteries while it is in the scanner. To charge it,
simply connect an AC or DC adapter to the scanner's
CHARGE jack.
It takes about 14–16 hours to recharge a battery pack (or
nickel-cadmium rechargeable batteries) that is fully dis-
charged. You can operate the scanner while recharging the
battery pack (rechargeable batteries), but charging takes
longer.
Note: A rechargeable battery pack (rechargeable batteries)
lasts longer if you let it fully discharge once a month. To do
this, simply use the scanner until BATT flashes and the scan-
ner beeps about every 3 seconds. Then fully charge it.
CONNECTING THE ANTENNA
Follow these steps to attach the supplied flexible antenna to
your scanner.
1. Align the slots around the scanner's connector with the
tabs on the ANT jack.
2. Press the antenna down over the jack and turn the
antenna's base clockwise until it locks into place.
Connecting an Optional Antenna
The ANT jack on the top of the scanner makes it easy to use
the scanner with a variety of antennas. Instead of the sup-
plied antenna, you can attach a different one, such as an
external mobile antenna or outdoor base station antenna.
Follow the installation instructions supplied with the antenna,
route the antenna cable to the scanner, then connect it to the
ANT jack.
PSR216OM.p65 2004/04/08, 16:49Page 6 AdobePageMaker6.5J/Win

7
Warning: Use extreme caution when installing or removing
an outdoor base station antenna. If the antenna starts to fall,
let it go! It could contact overhead power lines, if the an-
tenna 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.
USING THE BELT CLIP
You can use the belt clip for hands-free carrying when you
are on the go. Simply slide the belt clip over your belt or
waistband.
CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or mono
headphones with a 3.5 mm plug into the PHONE jack on top
of your scanner. This disconnects the internal speaker.
Caution: To protect your hearing, follow these guidelines
when you use an earphone or headphones:
•Do not listen at extremely high volume levels. Extended
high-volume listening can lead to permanent hearing loss.
•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.
Warning: Do not use an earphone or headphones with your
scanner when operating a motor vehicle or riding a bicycle,
in or near traffic. Doing so can create a traffic hazard and
could be illegal in some areas.
CONNECTING AN EXTENSION SPEAKER
In a noisy area, an amplified speaker might provide more
comfortable listening.
Plug the speaker cable's 3.5 mm plug into your scanner's
PHONE jack.

UNDERSTANDING BANK/BANDS/MONITOR
MEMORY
Channel Storage banks
To make it easier to identify and select the channels you want
to listen to, channels are divided into 10 banks of 20 chan-
nels each. Use each channel-storage bank to group frequen-
cies, such as those used by the fire department, ambulance
services, or aircraft.
PSR216OM.p65 2004/04/08, 16:50Page 10 AdobePageMaker6.5J/Win

11
For example, the fire department might use four frequen-
cies, one for each side of town. You could program the fire
frequencies starting with Channel 1 (the first channel in bank
1) and program the aircraft frequencies starting with chan-
nel 21 (the first channel in bank 2).
Search Bands
Your scanner can tune over 35,000 different frequencies.
Many of these frequencies are grouped within permanent
memory locations called search bands.
Band Displayed Search Range Freq. Coverage (MHz)
1 68–78 68.000 to 78.000
2 78–88 78.000 to 88.000
3 108–137 108.000 to 136.9875
4 137–144 137.000 to 143.995
5 144–146 144.000 to 146.000
6 146–174 146.005 to 174.000
7 380–450 380.000 to 450.000
8 450–512 450.000 to 512.000
9 806–880 806.000 to 880.000
0 880–960 880.000 to 960.000
You can search these bands to quickly find active frequen-
cies you might want to store into the scanner's channels.
Note: The frequencies in the scanner's search bands are
preset. You cannot change them.
Monitor Memory
The scanner also has a monitor memory that you can use to
temporarily store a frequency while you decide whether to
save it into a channel. This is handy for quickly storing an
active frequency when you are searching through an entire
band using direct search.

hear a hissing sound.
3. Turn the SQUELCH knob clockwise until the hissing sound
stops.
Notes:
•If the scanner picks up unwanted, partial, or very weak
transmissions, turn SQUELCH clockwise to decrease the
scanner's sensitivity to these signals. If you want to listen
to a weak or distant station, turn SQUELCH counterclock-
wise.
•If SQUELCH is adjusted so you always hear a hissing
sound, the scanner does not scan properly.
•If you have not stored frequencies into any channels, the
scanner does not scan.
PROGRAMMING FREQUENCIES
Your scanner is capable of storing up to 200 frequencies.
You can program the frequencies randomly or match chan-
nel numbers with car numbers, TV and radio call numbers,
etc.
To program frequencies:
1. Press PROG. PROG appears.
2. To select the channel where you want to store the fre-
quency, use the number keys to enter the channel num-
ber, then press PROG.
3. Using the number keys and •/DELAY, enter the frequency
you want to store into that channel.
4. Press ENT to store the frequency.
Notes:
•If you entered an invalid frequency in Step 3, the scanner
beeps and displays the channel number and Error. Sim-
ply repeat Steps 3 and 4.

13
•Your scanner automatically rounds the entered frequency
down to the closest valid frequency. For example, if you
try to enter a frequency of 151.473, your scanner accepts
it as 151.470
•If you entered a frequency that is already stored in an-
other channel, the scanner beeps three times and dis-
plays the lowest channel number where the frequency is
already stored, and –dUPL– briefly flashes about three
seconds. If you want to store the frequency anyway, press
ENT again.
5. Repeat Steps 2-4 to store more frequencies into chan-
nels.

play.
Note: You can still manually select locked-out channels.
To remove all lockout from a channels as follows:
1. Press MAN.
2. Press and hold CLEAR then press L/OUT. Lo ALL–CL
appears on the display.
3. Press ENT to clear all lock out. If you do not clear lock-
out, press CLEAR.
USING KEYLOCK
After programming your scanner, you can eliminate accidental
program and/or functional changes by locking the keypad.
To turn the keylock on, press and hold for approxi-
mately 3 seconds, or until the scanner beeps three times
and appears in the display. The only usable keys while
this function is active are , MAN, SCAN, LIGHT,
SQUELCH and VOLUME.
To turn the keylock function off, press and hold for
approximately 3 seconds until the scanner beeps three times
and disappears in the display.
USING DELAY
Many agencies use a two-way radio system that has a pe-
riod of several seconds between a query and a reply. To avoid
missing a reply, you can program a 2-second delay into any
channel or frequency. When your scanner stops on a chan-
nel or frequency with a programmed delay, DLY appears on
the display and the scanner continues to monitor that fre-
quency for 2 seconds after the transmission stops before
resuming scanning.
PSR216OM.p65 2004/04/08, 16:50Page 18 AdobePageMaker6.5J/Win

You can program a 2-second delay in these ways:
•If the scanner is scanning and stops on an active chan-
nel, quickly press •/DELAY before it continues scanning
again.
•If the desired channel is not selected, manually select the
channel, then press •/DELAY.
•If the scanner is in the search mode, press •/DELAY while
the scanner is searching. DLY appears on the display and
the scanner automatically adds a 2-second delay to ev-
ery transmission it stops on.
To turn off the 2-second delay, press •/DELAY while the scan-
ner is monitoring the channel or frequency. DLY disappears
from the display.
TURNING THE KEY TONE ON AND OFF
Each time you press any of the scanner's keys, the scanner
sounds a tone.
Follow these steps to turn the scanner's key tone on or off.
1. If the scanner is on, turn VOLUME counterclockwise until
it clicks to turn it off.
2. While you press and hold down 2and ENT, turn on the
scanner.
3. After a second, release 2and ENT.
BATTERY-SAVING FEATURE
Your scanner has been equipped with a battery-saving cir-
cuit. This feature sends the unit into a standby mode, which
uses only 30 percent of the available power, if no signal is
detected within a 5 second time interval, P.–SA (power save)
appears in the display.

GENERAL GUIDE TO SCANNING
BIRDIE FREQUNCIES
Every scanner has birdie frequencies. Birdies are signals
created inside the scanner's receiver. These operating fre-
quencies might interfere with broadcasts on the same fre-
quencies. If you program one of these frequencies, you hear
only noise on that frequency. If the interference is not se-
vere, you might be able to turn SQUELCH clockwise to cut
out the birdie.
The birdie frequencies on this unit to watch for are:
72.170 80.300 85.775 136.5125
144.550 150.150 152.575 160.605
168.635 385.450 392.925 393.725
401.7625 409.050 415.1875 425.1250
429.050 431.225 441.200 466.050
489.150 497.875 505.900 809.900
811.5625 819.600 825.9375 827.6375
836.700 814.975 843.7125 851.750
859.7875 867.250 891.925 899.9625
908.000 915.4375 924.075 930.1875
940.150 944.050 947.550 956.2125
To find the birdies in your scanner, being by disconnecting
the antenna and moving it away from the scanner. Make sure
that no other nearby radio or TV sets are turned on near the
scanner. Use the search function and scan every frequency
range from its lowest frequency to the highest. Occasionally,
the searching will stop as if it had found a signal, often with-
out any sound. That is a birdie. Make a list of all the birdies in
your scanner for future reference.
SPECIFIED INTERVALS
Frequencies in different bands are accessible only at spe-
cific intervals. For example:
