Delay

Many agencies use a two-way radio system that might have a period of 2 or
more seconds between a query and a reply. To keep from missing a reply, you
can program a 2-second delay into any channel or frequency. The scanner
continues to monitor the frequency for 2 seconds after the transmission
stops before resuming scanning or searching.

To program a 2-second delay:

  If the scanner is scanning channel-storage banks and stops on an active
  channel where you want to store a delay, quickly press DELAY before
  scanning resumes.  DELAY appears.

  If the desired channel is not selected, manually select the channel, then
  press DELAY.  DELAY appears.

  If the scanner is searching, press DELAY.  DELAY appears and the scanner
  automatically adds a 2-second delay to every transmission it stops on in
  that band or limit range.

  To turn off the 2-second delay, press DELAY while the scanner is
  monitoring the channel or searching service banks or limit ranges. DELAY
  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 30 channels in that bank.

While scanning, press the number key that corresponds to the bank you want
to turn on or off.  If the bank number is on, the bank is turned on and the
scanner scans all channels within that bank that are not locked out. If the
bank number is off, the scanner does not scan any of the channels within
that 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 is always active.

Locking Out Channels and Frequencies

You can scan existing channels or search frequencies faster by locking out
channels or frequencies that have a continuous transmission, such as a
weather channel.

Note: If you just want to skip over a lengthy transmission (such as a modem
      signal), see "Skipping Data Signals" below.

Locking Out Channels

To lock out a channel while scanning, press L/O when the scanner stops on
the channel.  To lock out a channel manually, select the channel and press
L/O until L/O appears.

Note:  You can still manually select locked-out channels.

To remove the lockout from a channel select the channel and press L/O until
L/O disappears.

To remove the lockout from all channels in the channel-storage banks that
are turned on, press MANUAL to stop scanning, then hold down L/O until the
scanner beeps twice.

Locking Out Frequencies

To lock out a frequency during a limit search or service bank search, press
L/O when the scanner stops on the frequency. The scanner locks out the
frequency, then continues searching.  To lock out a frequency manually,
select the frequency and press L/O until L/O appears.

Notes: The scanner does not display locked-out frequencies during a search.

       L/O appears when you select a locked-out frequency.

       You can lock out up to 50 frequencies during a limit search and 20
       during a service bank search.  If you try to lock out more
       frequencies, the first locked-out frequency is automatically
       unlocked.

To remove the lockout from a frequency select the frequency then press L/O.
L/O disappears.

To remove the lockout from all frequencies while searching, press HOLD then
hold down L/O until the scanner beeps twice (about 2 seconds).

Priority

The priority feature lets you scan through channels and still not miss
important or interesting calls on specific channels.  You can program one
stored channel in each bank as a priority channel (for up to a total of 10
stored channels).  As the scanner scans the bank, if the priority feature
is turned on, the scanner checks the priority channel for activity every 2
seconds.

The scanner automatically designates each bank's first channel as its
priority channel. Follow these steps to select a different channel as the
priority channel for a bank.

1.  Press MANUAL.

2.  Enter the channel number you want to select as the priority channel,
    then press MANUAL again.

3.  Hold down PRIORITY until the scanner beeps twice.  [P] appears to the
    right of the channel number.

4.  Repeat Steps 2-3 for the channel in each bank you want to program as a
    priority channel.

To turn on the priority feature press PRIORITY during scanning. PRI appears.
As you scan the bank, the scanner checks the bank's priority channel every
2 seconds in each bank that is turned on, starting from the lowest to the
highest-numbered priority channel.

To turn off the priority feature, press PRIORITY.  PRI disappears.

Notes: The priority feature must be turned off to use the data skip feature
       (see "Skipping Data Signals" below).

       You can lock out priority channels.  If you lock out all priority
       channels, [P] CH Loc Out appears when you turn on the priority.

Turning The Key Tone ON and OFF

To turn the key tone off, turn off the scanner.  Then, while holding down
L/O/SKIP, turn on the scanner, oN bEEP appears.

To turn the key tone back on, repeat the above procedure, oN bEEP appears.

Changing Search Speeds

The PRO-2050 has two search speeds for a limit search.

    Normal Search                   HyperSearch

  100 steps/second                300 steps/second

To switch between the normal and HyperSearch speeds, during a limit search,
press SPEED.  SEARCH flashes during HyperSearch.

Note:  You can use HyperSearch only in the 5 kHz step bands (29-54 MHz and
       137-174 MHz).

Skipping Data Signals

You can set the scanner so it skips nonmodulated or data signals (such as
modem transmissions) during a scan or search.

Note:  Since data signals are not generally found in the air band, this
       feature does not work in the air service bank.

       To turn on the data skip feature, be sure the priority feature is
       turned off (see "Priority" above), then press DATA.  DATA appears.
       To turn off the feature, press DATA again.  DATA disappears.
