SCANNING THE STORED 
CHANNELS
To begin scanning channels, press SCAN. The scanner
scans through all non-locked channels in the activated
banks. (See “Locking Out Channels” on Page 34 and
“Turning Channel-Storage Banks On and Off” on
Page 33). When the scanner finds a transmission, it
stops on it. When the transmission ends, the scanner
resumes scanning.
Notes:
• If you have not stored frequencies into any chan-
nels, the scanner does not scan.
• If the scanner picks up unwanted partial, or very
weak transmissions, turn 
SQUELCH clockwise to
decrease the scanner’s sensitivity to these  sig-
nals. To listen to a weak or distant station, turn
SQUELCH counterclockwise.
• To ensure proper scanning, adjust 
SQUELCH until
the audio mutes.
• To scan in the trunk scanning mode, see “Trunking
Operation” on Page 41.
MANUALLY SELECTING A
CHANNEL
You can continuously monitor a single channel without
scanning. This is useful if you hear an emergency
broadcast on a channel and do not want to miss any
details — even though there might be periods of silence
— or if you want to monitor a specific channel. 
To manually select a channel, press 
MAN, enter the
channel number then press 
MAN again.
Or, if while scanning, the radio stops at a channel you
want to listen to, press 
MAN one time. (Repeatedly
pressing 
MAN at this time causes the scanner to step
through the channels.) Press 
SCAN to resume automat-
ic scanning.

SPECIAL FEATURES
DELAY
Sometimes a user might pause before replying to a
transmission. To avoid missing a reply on a specific
channel, you can program a 2-second delay into any
channel or frequency. The scanner continues to moni-
tor the channel frequency for an additional 2 seconds
after the transmission stops before resuming scanning
or searching.
Depending on how the scanner is operating, follow one
of these steps to program a delay.
• If the scanner is
scanning and stops
on an active channel
where you want to
store a delay, quickly
press 
DELAY before it
continues scanning
again. 
DLY appears.
• If the desired channel is not selected, manually
select the channel, then press 
DELAY. DLY ap-
pears.
• If the scanner is searching, press 
DELAY while the
scanner is searching. 
DLY appears and the scan-
ner automatically adds a 2-second delay to every
frequency it stops on in that band.
To turn off the 2-second delay, press 
DELAY while the
scanner is monitoring a channel, scanning, or search-
ing. 
DLY disappears.
TURNING CHANNEL-STORAGE 
BANKS ON AND OFF
You can turn each channel-storage bank on and off.
When you turn off a bank, the scanner does not scan
any of the 50 channels in that bank.
20-524.fm  Page 33  Tuesday, August 31, 1999  3:55 PM 
						

							34
While scanning, press the number key that corresponds
to the bank you want to turn on or off. Numbers appear
at the top of the display, showing the currently selected
banks.
The scanner scans all the channels within the displayed
banks that are not locked out (see “Locking Out Chan-
nels”). The bank number flashes when the scanner
scans the channel that belongs to the bank.
Notes:
• You can manually select any channel within a
bank, even if that bank is turned off.
• You cannot turn off all banks. One bank must
always be active.
LOCKING OUT CHANNELS
You can increase the scanning speed by locking out
channels that have a continuous transmission, such as
a weather channel. To lock out a channel, manually
select the channel, then press 
L-OUT(S/S).   L/O ap-
pears. 
Note: 
You can still manually select locked-out chan-
nels.
To remove the lockout from a channel, manually select
the channel, then press 
L-OUT(S/S). L/O disappears.
To unlock all channels in the banks that are turned on,
press 
MAN to stop scanning, then hold down L-OUT(S/S)
until the scanner beeps twice.
PRIORITY
The priority feature lets you scan through the channels
and still not miss important or interesting calls on spe-
cific channels. You can program one stored channel in
each bank as a priority channel (10 for the banks in
Group A and 10 for the banks in Group B). If the priority
feature is turned on, as the scanner scans the bank, it
checks that bank’s priority channel for activity every 2
seconds.

The scanner automatically designates each banks first
channel as its priority channel. Follow these steps to
select a different channel in a bank as the priority chan-
nel.
1. Press 
PROG.
2. Enter the channel number you want to select as
the priority channel, then press 
PRIORITY (H/S). 
appears to the right of the selected channel num-
ber.
3. Repeat Steps 1 and 2 for the channel in each bank
you want to program as a priority channel.
To review all priority channels (in ascending order
only), press 
PROG, then repeatedly press PRIORITY to
see the numbers of the priority channels.
To turn on the priority feature, press 
PRIORITY during
scanning. 
PRI appears. Then the scanner checks the
designated priority channel every 2 seconds in each
bank. The bank number appears at the top of the dis-
play.
To turn off the priority feature, press 
PRIORITY. PRI
disappears.
Notes:
• The priority feature must be turned off to listen to
the monitor memories or to use the data skip fea-
ture.
• If you have locked out all priority channels,
 appears when you activate the priority
feature. To unlock any desired priority channels,
see “Locking Out Channels” on Page 34.

SKIPPING DATA SIGNALS
To prevent the scanner from stopping on channels that
consist of nonmodulated or data signals (such as fax or
modem transmissions) during a search or scan, turn on
the data skip feature. When the radio receives a data
signal and data skip is selected, the signal is ignored.
To turn on the data skip feature, turn off the priority fea-
ture if it is on (see “Priority” on Page 34), then press 
DA-
TA
. DATA
 appears. To turn off the data skip feature,
press 
DATA again. DATA disappears.
Note:
 This feature does not apply to the air service
band as data signals are not generally found in this ser-
vice.
RECEIVING NWR-SAME AND 
WEATHER ALERT SIGNALS
In 1994, the National Oceanic and Aerospace Adminis-
tration (NOAA) began broadcasting alerts that include
digitally encoded data. 
Specific Area Message Encod-
ing
 (SAME) includes information which identifies the se-
verity of the alert. The PRO-94 displays this data as
codes corresponding to the levels of severity (L1, L2,
and L3). 
Tu r n i n g  O n  t h e  S A M E
Weather Alert Feature
1. Press SVC (E) and select the weather search
mode. See “Service Bank Search” on Page 29.
2. Press 
ALT (DATA). This mutes the audio until the
scanner receives a SAME coded signal.
20-524.fm  Page 38  Tuesday, August 31, 1999  3:55 PM 
						

							39
When the scanner receives a SAME coded signal,
ALERT flashes and an associated “L” code (which indi-
cates the severity of the alert) appears, as well. The
scanner remains on the weather channel and the audio
turns on so you can hear the  weather broadcast.
The scanner displays one of the following codes to indi-
cate the alert level.
L1: Warning
L2: Watch
L3: Statement
-----: Non-emergency
In addition to weather alerts, the scanner also receives
test and other event information. See “NWR-SAME
Code Detection Tests” on Page 40.
SAME Signal Detection Updating
When the scanner receives a SAME-coded signal, it re-
tains information about the most recent alert until you
turn off the power. Once the scanner detects an alert
code, 
ALERT flashes. To verify the specific alert level
(L1, L2, or L3) press 
SVC (E) to select the weather
search mode. Press 
ALT (DATA) to clear the alert.
20-524.fm  Page 39  Tuesday, August 31, 1999  3:55 PM

NWR-SAME Alert Tone Test
To hear and test the tones for the three alert levels,
press 
SVC (E) to select the weather service, then hold
down 
ALT for about 1 second. The tones sound in the
order L3, L2, then L1, and 
TESt flashes. Each alert
code appears as its tone sounds. Press any key to end
the test sequence.
NWR-SAME Code Detection Tests
The National Weather Service sends out daily, weekly,
and monthly test (and sometimes demonstration) sig-
nals, which let anyone with a receiver (such as the
PRO-94) verify that the equipment is working properly.
To find out the specific test schedule in your area, con-
tact your local NOAA or NWS office. Those offices are
usually listed in the telephone book under 
US Govern-
ment, Department of Commerce
.
When 
ALERT appears, hold down ALT (DATA) for about
1 second. The frequency and 
TESt appear alternately.
When the scanner receives the test code, 
TSt also ap-
pears .
To exit the test mode, press 
ALT (DATA) for about 1 sec-
ond.
Note
: If an actual alert is sent, the scanner sounds the
appropriate tone and displays the corresponding alert
level.
