(200-0524)                 Operation                  Faxback Doc. # 57985

Turning On The Scanner And Setting Squelch

Note:  Make sure the scanner's antenna is connected before you turn it on.

1.  Turn SQUELCH fully counterclockwise. 

2.  Turn VOLUME/OFF clockwise until it clicks and you hear a hissing 
    sound.

3.  If the PRO-94 is scanning, press MAN (manual) to stop scanning, then 
    turn SQUELCH clockwise until the hissing stops.

Storing Known Frequencies Into Channels

You can locate and store specific frequencies into channels for later use.  
To assist you in locating a desired frequency from the scanner's wide 
range, consider using a frequency guide.  Good references for active 
frequencies are the RadioShack "Police Call Guide including Fire and 
Emergency Services," and "Official Aeronautical Frequency Directory."  We 
update these directories every year, so be sure to get a current copy.

Note:  To store trunked system frequencies, see "Storing Trunked 
       Frequencies" in Faxback Doc. # 57987.

Follow these steps to store frequencies into channels. 

1.  Press MAN and hold down A/B (HOLD) for about 2 seconds to select 
    either main bank group.  Enter the channel number where you want to 
    store a frequency, then press PROG.  The channel number appears.

2.  Use the number keys and (.)(MON/CLR) to enter the frequency (including 
    the decimal point) you want to store. 

3.  Press E (SVC) to store the frequency into the channel.

    Notes:  If you entered an invalid frequency in Step 2, Error appears 
            and the scanner beeps three times.  Enter a valid frequency. 

            The scanner automatically rounds the entered number to the 
            nearest valid frequency.  For example, if you enter 151.473 
            (MHz), your scanner accepts it as 151.475.

            Press DELAY to pause scanning 2 seconds after the end of a 
            transmission before scanning proceeds to the next channel (see 
            "Delay" in Faxback Doc. # 57986).  The scanner stores this
            setting in the channel.

4.  To program the next channel in sequence, press PROG and repeat Steps
    2 and 3.

Searching For And Temporarily Storing Active Frequencies

If you do not have a reference to frequencies in your area, use a limit, 
direct, or service search (except weather service search) to find a 
transmission.  Also see "Guide to the Action Bands" in Faxback Doc. # 
17653.

Note:  While doing a limit, direct, or service bank search, press:

          DELAY if you want the scanner to pause 2 seconds after a 
          transmission ends before it proceeds to the next frequency (see 
          "Delay" in Faxback Doc. # 57986).

          DATA if you want the scanner to skip data signals (such as fax 
          or modem signals) and search only for audio (voice) signals (see 
          "Skipping Data Signals" in Faxback Doc. # 57986).

Limit Search

A limit search lets you search within a specific range of frequencies.
-L- appears during a limit search.

1.  Press PROG, then LIMIT (SRC).  Lo and 29.000 MHz appear.  29.000 MHz
    is the low end of the scanner's range. 

2.  Enter the frequency that is the lower limit of the range you want to 
    search (including the decimal point), then press E.

3.  Press LIMIT.  Hi and 1300.00 MHz appear.  1300.000 MHz is the upper
    limit of the scanner's range.

4.  Enter the frequency that is the upper limit of the range you want to
    search (including the decimal point), then press E (SVC) again.

5.  Press \/ to search from the upper to the lower limit or /\ to search  
    from the lower to the upper limit.

6.  When the scanner stops on a transmission, quickly press either:

      HOLD (A/B) to stop searching to listen to the transmission.  HOLD 
      appears.

      MON/CLR (.) to store the displayed frequency into the current 
      monitor memory.

7.  To release the hold and continue searching, press HOLD (A/B) or hold
    down \/ or /\ for at least 1 second.  Or, if you did not press MON/CLR
    (.), simply press \/ or /\ to continue searching.

Direct Search

You can search up or down from the currently displayed frequency using 
direct search.  -d- appears during searching until the scanner stops.
See Step 4.

1.  Press MAN.

2.  Enter the frequency you want to start from using the number keys.  
    (Press [.] to enter a decimal point).

    Notes:  To start the search from a frequency already stored in one of 
            your scanner's channels, press MAN or PROG.  Then use the 
            number keys to enter the channel number and then press MAN or 
            PROG again.

            If you enter an invalid frequency, the scanner displays Error.
            Press MON/CLR (.).

3.  Press \/ to search downward or /\ to search upward from the selected 
    frequency.  -d-, SEARCH, and \/ or /\ appear.

4.  When the scanner stops on a transmission, quickly press either:

      HOLD to stop searching and listen to the transmission.  HOLD 
      appears.

      MON/CLR to store the displayed frequency into the current monitor 
      memory.

5.  To release the hold and continue searching, press HOLD or hold down \/
    or /\ for at least 1 second.  Or, if you did not press HOLD, simply
    press \/ or /\ to continue searching.

    Note:  To step through the frequencies while HOLD appears, press 
           \/ or /\.

Service Bank Search

You can search for weather, ham, marine, aircraft, or police (fire/ 
emergency) transmissions without knowing the specific frequencies used in 
your area. The scanner is preprogrammed with all the frequencies allocated 
to these services.  To use this feature, press SVC.  SEARCH appears and
the scanner searches starting with the weather service bank.  To select a
different service bank, repeatedly press SVC.  A bar appears above the
selected bank.

When the scanner stops on a transmission, quickly press either:

  HOLD to stop searching and listen to the transmission.  HOLD appears.

  MON/CLR to store the displayed frequency into the current monitor memory 

To release the hold and continue searching, press HOLD (A/B) or hold down 
\/ or /\ for at least l second.  Or, if you did not press HOLD (A/B), 
simply press \/ or /\ to continue searching. 

Note:  Because there are many different frequencies allocated to fire and 
       police departments, it can take several minutes to search all the 
       service frequencies. 

Search Skip Memory

You can skip up to 20 specified frequencies during a limit or direct 
search and up to 20 specified frequencies during a service bank search.
This lets you avoid unwanted frequencies or those already stored in a 
channel. 

To skip a frequency, press S/S (L-OUT) when the scanner stops on the 
frequency during a limit, direct, or service search.  The scanner stores 
the frequency in memory and automatically resumes the search.

To clear a single frequency from skip memory so the scanner stops on it 
during a limit, direct, or service bank search:

1.  Press HOLD to stop the search.

2.  Press \/ or /\ to select the frequency.  L/O appears.

3.  Press S/S.  L/O disappears. 

To clear all the skip frequencies at once while searching, press HOLD then 
hold down S/S until the scanner beeps twice. 

Notes:  If you selected all frequencies to be skipped within the search 
        range, the scanner beeps 3 times and does not search.

        If you select more than 20 frequencies to skip, each new frequency 
        replaces a frequency previously stored, beginning with the first 
        stored frequency.

        Press \/ or /\ to select a skipped frequency while HOLD appears.
        L/O appears when you select a skipped frequency.

Listening To The Monitor Memories

To listen to the frequency stored in any one of the ten monitor memories, 
press MAN, MON/CLR (.) then the number of the desired monitor memory (0-9)
or repeatedly press MON/CLR (.) to step through the monitor memories.

Note:  To listen to the monitor memories, the priority channel feature 
       must be turned off (see "Priority" in Faxback Doc. # 57986).

Moving A Frequency From A Monitor Memory To A Channel

1.  Press MAN.  MAN appears.

2.  Enter the number of the desired target channel where you want to move 
    the frequency that is stored in the monitor memory, then press PROG.
    PGM appears.

3.  Press MON/CLR (.) then enter the number (0-9) of the monitor memory
    containing the frequency.

4.  Press E. The frequency transfers from the monitor memory into the 
    selected channel.

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" 
and "Turning Channel-Storage Banks On and Off" in Faxback Doc. # 57986).
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 channels, 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 signals.  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" in 
        Faxback Doc. # 57987.

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 automatic 
scanning.
