PRO-2050 VHF/UHF/Air/800 MHz 300-Channel Trunk Tracker Home Scanner
(200-0430A)                Operation                  Faxback Doc. # 61192

Turning On The Scanner and Setting Squelch

1.  Turn SQUELCH and VOLUME fully counterclockwise.

2.  Turn VOLUME back clockwise until you hear a hissing sound.

3.  Turn SQUELCH clockwise, then leave it set to a point just after the
    hissing sound stops.

Notes: If the scanner will not scan, turn SQUELCH further clockwise.

       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 counterclockwise.

       If SQUELCH is adjusted so you always hear a hissing sound, the
       scanner does not scan properly.

Storing Known Frequencies Into Channels

Good references for active frequencies are the RadioShack "Police Call
Guide including Fire and Emergency Services," "Official Aeronautical
Frequency Directory," and "Maritime Frequency Directory." We update these
directories every year, so be sure to get a current copy.

Note: To store trunking system frequencies, see "Programming Trunked
      Frequencies" on Faxback Doc. # 61195.

Follow these steps to store frequencies into channels.

1.  Press MANUAL, enter the channel number (1-300) where you want to store
    a frequency, then press MANUAL again.  The channel number appears.

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

3.  Press E to store the frequency into the channel.

    Notes: If you made a mistake in Step 2, Error appears and the scanner
           beeps when you press E.  Simply start again from Step 2.

           Your scanner automatically rounds the entered frequency to the
           nearest valid frequency.  For example, if you enter a frequency
           of 151.473, your scanner accepts it as 151.475.

           If you entered a frequency that is already stored in another 
           channel, the scanner beeps three times and displays the lowest 
           channel number where the frequency is already stored.  If you
           want to store the frequency anyway, press E again.

           Press DELAY if you want the scanner to pause 2 seconds on this
           channel after a transmission ends before it proceeds to the
           next channel (see "Delay" on Faxback Doc. # 61193). The scanner
           also stores this setting in the channel.

4.  If you want to program the next channel in sequence, press MANUAL and
    repeat Steps 2 and 3.

Searching Service Banks

You can search for public service, police, fire/emergency, aircraft, and
weather transmissions even if you do not know the specific frequencies 
that are used in your area.  And, you can store any of the frequencies you 
find into channels.

Your scanner has the following preprogrammed service banks.

  PUBLIC - contains 140 public service frequencies.

  POLICE - contains 2,392 police frequencies.

  FIRE/EMG - contains 197 fire and emergency service frequencies.

  AIR - contains 2,319 aircraft and air service frequencies.

  WX - contains 7 weather frequencies.

To select a service bank, press SVC.  A service bank's name (PUB, POLICE,
FIRE/EMG, AIR or WX) and one of the preset public service frequencies
appear.  After a 2-second delay, searching begins.

To select another service bank, repeatedly press SVC until the scanner
displays the name of the bank you want to use.

Notes: To skip data signals (such as modem signals), press DATA.  See
       "Skipping Data Signals" on Faxback Doc. # 61193.

       Because frequencies are not always assigned to the same services
       everywhere, you might hear transmissions from one service in
       another service group.

Press SEARCH to start searching immediately or to continue searching if 
you want to skip a frequency.

During service-search, you can press HOLD to pause the searching.  HOLD
appears.  Press /\ or \/ to move up or down one step, or press SEARCH to
resume searching.

Follow these steps to store frequencies into channels.

1.  Press MANUAL.

2.  Use the number keys to enter the channel number (1-300) where you want
    to store the frequency, then press MANUAL.

3.  Press SVC then SEARCH to select a service bank and begin searching.

4.  When the scanner stops on a transmission, press HOLD.  The frequency
    appears.

5.  Press E to store the frequency into the channel.

Limit Search

If you do not know a frequency to store, you can search for transmissions
within a range of frequencies you select, called the limit search range.
Then you can store any interesting frequencies you find into channels.

1.  Press MANUAL, enter the channel number where you want to store a
    frequency, then press MANUAL again.  The channel number appears.

2.  Use the number keys and (.) to enter the frequency that is the lower
    limit of the range you want to search.

3.  Press LIMIT.

4.  Use the number keys and (.) to enter the frequency that is the upper
    limit of the range you want to search.

5.  Press LIMIT, then press SEARCH.  The scanner begins to search from the
    lower limit to the upper limit.

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

      E to store the displayed frequency into the channel.  The scanner
      stores the frequency.

      /\ or \/ to stop searching so you can listen to the transmission.
      HOLD appears.

      To release hold and continue searching, press SEARCH.

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

       If you tune to a search skip frequency, L/O appears.  See "Locking
       Out Channels and Frequencies" on Faxback Doc. # 61193.

       To skip data signals (such as modem signals), press DATA.  See
       "Skipping Data Signals" on Faxback Doc. # 61193.

Scanning The Stored Channels

To begin scanning channels, press SCAN.  The scanner scans through all
non-locked channels in all banks that are turned on, then stops on the 
first transmission it finds.  When the transmission ends, the scanner 
resumes scanning.

Notes: Channels with no frequencies are automatically locked out during
       scanning.

       To scan in the trunk tracking mode, see "Scanning a Trunked Bank"
       on Faxback Doc. # 61195.

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.

Follow these steps to manually select a channel.

1.  Press MANUAL.

2.  Enter the channel number.

3.  Press MANUAL again.

Or, if your scanner is scanning and stops at the desired channel, press
MANUAL one time.  (Pressing MANUAL additional times causes your scanner to
step through the channels.)

To resume scanning, press SCAN.

Clearing A Frequency From A Channel

1.  Press MANUAL.

2.  Use the number keys to enter the channel number containing the
    frequency you want to delete.  Then press MANUAL again.

3.  Press O, then E.  The frequency is deleted.
