PROGRAMMING THE PRO-2005 SCANNER
1. Select a channel to program by pressing [MANUAL], and entering the
channel number you want to program. Then, press [PROGRAM]. "PROGRAM"
appears in the display to indicate that your scanner is in the
programming mode.
2. Enter a frequency. A good reference for active frequencies is Radio
Shack's "Police Call Guide Including Fire and Emergency Services,".
We update these directories every year, so be sure to get a current
copy.
3. Press [ENTER]. This stores the frequency. If you make a mistake in
Step 2, "ERROR" appears on the display and three beeps sound. Press
[CLEAR] and proceed again from Step 2.
4. Press [DELAY]. If you want your scanner to pause after each
transmission before scanning to the next channel, press [DELAY].
"DELAY" appears in the display. If you do not want your scanner to
pause, press [DELAY] again. "DELAY" disappears from the display.
5. Repeat Steps 1-4 to program more channels.
NOTE: If you want to program the next channel in sequence, just press
[PROGRAM} and proceed to Step 2.
SEARCHING FOR ACTIVE FREQUENCIES
Use these procedures to search for a transmission. This is helpful if you
do not have a reference to frequencies in your area. Also see "A Guide to
the Action Bands" in this manual.
LIMIT SEARCH
The limit search procedure allows you to search within a range of
frequencies. You can store up to ten limit search ranges in the search
banks.
1. Press [PROGRAM], and the search bank number in which you wish to store
the limit search range. Press [0] for bank number 10.
2. Press [LIMIT]. "L" and the search bank number appears in the display.
3. Enter the lower limit of the frequency range. Then, press [ENTER].
4. Press [LIMIT]. "L" changes to "H" in the display.
5. Enter the upper limit of the frequency range. Then, press [ENTER].
6. Repeat steps 1-5 to store the limit search range into the search
banks. You can store up to 10 limit-search ranges.
7. To recall a limit-search range, press the appropriate bank number.
8. Press [UP-ARROW] to search from upward starting from the lower
limit. Or, press [DOWN-ARROW] to search from the upper limit to the
lower limit.
9. When the scanner stops on a transmission, press [MONITOR] to store the
frequency in the current monitor memory. The memory number flashing on
the display indicates the current monitor memory.
10. Press [UP-ARROW] or [DOWN-ARROW] to continue the search.
NOTES: Press [SPEED] to speed up or slow down the search.
Press [DELAY] to make the scanner pause 2 seconds after a
transmission, before proceeding to the next frequency.
LIMIT-SEARCH MEMORY
When you change your scanner's mode from limit search to manual, program,
scan, direct search, and so on, your scanner retains the last frequency
before you change the mode. Your scanner resumes the search from that
frequency when you change the mode to limit search again.
NOTE: You can change the upper or lower limit frequency without affecting
the memorized frequency if the frequency is within the new limit
range. If the frequency is out of the new limit range, the search
starts from the new upper or lower limit frequency.
DIRECT SEARCH
When you are in program or manual mode, you can search up or down from
the current frequency.
1. Select a currently programmed channel by pressing [MANUAL], and the
channel number. Then, press either [MANUAL] or [PROGRAM].
2. Press [DIRECT]. The step frequency appears in the display.
3. Press [UP-ARROW] to search through higher frequencies or press [DOWN-
ARROW] to search through lower frequencies.
4. When the search stops on a transmission, you can store that frequency
into a monitor memory by pressing [MONITOR]. The memory number
flashing on the display indicates the current memory number. To
continue the search, press [DOWN-ARROW] or [UP-ARROW].
NOTES: When you press [DIRECT] during limit, your scanner enters direct
search mode.
When you press a numeric key during a direct search, your scanner
changes to limit search mode. The key you press corresponds with
the limit-search bank number.
MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL
As you store frequencies in monitor memories, the memory number flashing on
the display shows the current monitor memory. You can listen to monitor
memories by press [MANUAL], [MONITOR], then the number of the monitor
memory you wish to listen to.
If there is a frequency you wish to transfer to a channel, follow these
steps to move it from a monitor memory
1. Press [MANUAL]. Enter the channel number you want to store the
monitor frequency in. Then press [PROGRAM].
2. Press [MONITOR] and the monitor memory number you want to move.
3. Press [ENTER]. The scanner stores the monitor frequency in the
channel.
If you want to return to a limit search after this procedure, press
[LIMIT], and the search bank number. Then, press either [UP-ARROW] or
[DOWN-ARROW] to continue searching.
UNDERSTANDING BAND MODES AND FREQUENCY STEPS
We designed your scanner to adjust itself for the band modes and frequency
steps for each frequency range. Default settings are shown below:
FREQUENCY VS. MODE AND STEP
FREQUENCY (MHz) MODE STEP (kHz)
25.000 - 29.995 AM 5
30.000 - 87.495 NFM 5
87.500 - 107.995 WFM 50
108.000 - 135.995 AM 12.5
136.000 - 224.995 NFM 5
225.000 - 520.000 NFM 12.5
760.000 - 1300.000 NFM 12.5
WFM: Wideband FM for normal FM broadcasts or TV sound
NFM: Narrowband FM for action radio bands, police, fire, ambulance,
ham radio and so on.
AM: For aircraft band, CB and so on.
Normally, the preset mode/step works within each band as shown above
However, for some of the ham radio, military aircraft (225-400 MHz), and
TV audio (WFM) bands, you must change the mode or step manually. To change
the band mode, press [MODE] when your scanner is in manual mode. To change
the frequency step, press [STEP] in search mode. Note that when you change
the preset modes/steps, the corresponding indicator flashes to show you
that you have changed the default setting.
When you want to return to the default setting, press [RESET]. The display
stops flashing.
Keep in mind that improperly setting the modes or steps can cause poor
reception. When you listen to an FM broadcast or TV sound in the NFM mode,
the sound is very distorted. If you monitor police band in WFM mode, the
sound is masked by the noise. Or if you use 5 kHz or 12.5kHz steps to
search for FM broadcasts or TV sound, the search might stop on the sideband
of the frequency. In that case, press [Up-Arrow] or [Down-Arrow] to get
the center frequency. If you use 50 kHz steps for NFM band, you might miss
the frequencies between the 50 kHz steps.
USING THE RESTART SWITCH
The scanner's display might lock up the first time you plug in and turn on
your scanner, or if the battery is left out for an extended period of time.
If the display locks, use a pointed object, like a paper clip, to press and
release the restart switch while power is on.
To clear all the memories, be sure the scanner is turned on and:
1. Press and hold [CLEAR].
2. Using a pointed object, press and release the restart switch.
3. After confirming that the display goes blank, release [CLEAR].
SETTING THE VOLUME AND SQUELCH
Turn VOLUME clockwise and SQUELCH counterclockwise until you hear a
hissing sound. Then slowly turn SQUELCH clockwise until the noise stops.
Leave VOLUME set to a comfortable listening level.
If the scanner picks up unwanted weak transmissions, turn SQUELCH clockwise
to decrease the scanner's sensitivity to these signals.
USING THE SOUND SQUELCH SWITCH
If the scanner stops at a transmission during scan, search, or priority
modes, the [SOUND SQUELCH] switch lets the scanner start scanning again if
the transmission contains no sound (carrier only without modulated
signals).
If your scanner stops at a frequency that has no sound, press [SOUND
SQUELCH]. The indicator lights. If the scanner detects no sound within
0.5 seconds, it goes to the next transmission.
When the scanner receives a frequency that contains sound, it halts at the
frequency. If the sound ceases, the scanner stays on the frequency for 5
seconds, and resumes scanning. If the carrier stops, the scanner begins to
scan immediately if the delay function is off, or after 2 seconds if the
delay function is on.
To cancel sound squelch, press [SOUND SQUELCH] again. The indicator goes
off.
NOTE: If a frequency contains a transmission with low modulation, the
sound squelch circuit might not work properly.
SCANNING THE CHANNELS
To begin scanning the channels, just press [SCAN]. Your scanner scans
through all the channels that you have not locked out of the banks that are
turned on. You must set SQUELCH so that you do not hear hissing sounds
between transmissions. Be sure to read the following sections to get the
full benefits from all of your scanner's special features.
USING THE DELAY FEATURE
Many agencies use two-way radio systems that might have a pause of
several seconds between a query and a reply. To keep from missing a reply,
program a delay on the channels you identify as operating this way. To
program a delay, manually select the channel and press [DELAY]. "DELAY"
appears on the display. Now, when you are scanning through channels, your
scanner pauses for two seconds after the completion of each transmission on
that channel before resuming scanning.
Some radio systems, especially those above 800 MHz, use a special "trunked"
system. In these systems, the transmitter selects an available frequency
each time the operator keys the radio. Therefore, it is possible for the
query to be on one frequency and the reply on another. To ensure the best
possibility of hearing the full reply, you want the scanner to begin
scanning immediately when the first transmission ends. In this case,
select the channel manually and ensure that "DELAY" is not in the display.
If "DELAY" is indicated, press [DELAY] to turn off this feature for that
channel.
SETTING THE SCANNING SPEED
The scanner has 2 different scanning speeds - 8 channels per second and 16
channels per second. To switch between the two scanning speeds, press
[SPEED] during scanning.
LOCKING OUT CHANNELS
You can increase the effective scanning speed by locking out channels that
you have not programmed. Manually select the channel and press [L/OUT] so
that "LOCK OUT" appears on the display. This is also handy for locking out
channels that have a continuous transmission, such as a weather channel.
You can still manually select locked-out channels for listening.
To disable the lock-out function, manually select the channel and press
[L/OUT], Or, press [L/OUT RVW] in manual or program mode to call out
locked-out channels one by one. Then, press [L/OUT] again.
NOTE: You can lock out as many channels as you like. But, there must be
at least one channel that you have not locked out in each bank.
TURNING BANKS ON AND OFF
As explained in "Understanding Channel Storage Banks and Search Banks" your
scanner splits the 400 channels into ten banks of forty channels each. The
small bars under the numbers at the top of the display are the bank
indicators. You can turn each bank on and off, so that all the channels in
a bank are either scanned or locked out. In scan mode, press the number
key for the bank you want to turn on or off. If the bank indicator is on,
you have turned on the bank and the scanner scans all the channels within
that bank that you have not locked out. If the indicator is off, the
scanner does not scan any of the channels within that bank. You can still
manually select any channel in a bank, even if you have turned off the
bank. You cannot turn off all banks - one must be turned on.
USING THE PRIORITY FEATURE
You can scan through the programmed channels, and still not miss an
important or interesting call on a specific channel. Simply program your
desired channel as the priority channel, and turn on the priority feature
by pressing [PRI] during scanning. The scanner now checks the priority
channel every two seconds, and stays on the channel if there is any
activity.
To program a priority channel, simply press [PROGRAM] and the desired
channel number. Then press [PRI]. "P" appears on the display whenever the
scanner is set to the priority channel. You can only program one channel
as the priority channel. If you program a new channel as the priority
channel, the previous channel you chose is automatically cleared.
NOTE: Channel 1 is automatically designated as the priority channel the
first time you turn on your scanner.
MANUALLY SELECTING A CHANNEL
You can continuously monitor a specific 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 channel you have locked-out. To select a channel to
monitor, just press [MANUAL], and enter the channel number. Then, press
[MANUAL] again. Or, if your scanner is scanning and has stopped at the
desired channel, just press [MANUAL] once. Pressing [MANUAL] additional
times causes your scanner to step through the channels one at a time.
DIMMER
Press [DIMMER] to turn the display's backlight down or up.
