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 on
a specific channel, you can program a 2-second delay into any channel or
frequency.  The scanner continues to monitor the channel frequency for 2
seconds after the transmission stops before resuming scanning or
searching.

To program a 2-second 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 appears.

  If the scanner is searching, press DELAY while the scanner is searching.
  DLY appears and the scanner 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 searching.  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 30 channels in that bank.

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 Channels").

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.  L/O appears.

Note:  You can still manually select locked out channels.

To remove the lockout from a channel, manually select the channel, then
press 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 until the scanner beeps twice.

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 5
stored channels).  If the priority feature is turned on, as the scanner
scans the bank, it checks that bank's priority channel every 2-seconds for
activity.

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

1.  Press PROG.

2.  Enter the channel number you want to select as the priority channel,
    then press PRIORITY.  P appears to the right of the channel number.

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, 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.  Every 2 seconds the scanner checks the priority channel in each
bank that is turned on.

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 feature.

        You can lock out all priority channels, LOC OUt appears when you
        turn on the priority feature.

USING THE KEYLOCK

Once you program your scanner, you can protect it from accidental program
changes by turning on the keylock feature.  When locked, the only controls
that operate are SCAN, MAN, KEYLOCK, VOLUME/OFF, and SQUELCH.

Note:  The keylock does not prevent the scanner from scanning channels.

To turn on the keylock, hold down KEYLOCK until K/L appears.  To turn it
off, hold down KEYLOCK until K/L disappears.

USING THE DISPLAY BACKLIGHT

You can turn on the display light for easy viewing at night.  Press
(symbol) to turn on the display light for 15 seconds.  To turn off the
light before 15 seconds elapse, press the button again.

CHANGING SEARCH SPEEDS

The PRO-91 has two search speeds.

      Normal Search                    Hypersearch

    100 steps/second                 300 steps/second

To switch between the normal and Hypersearch speeds during limit search or
direct search, press H/S.  HYPER appears during Hypersearch.

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

TURNING THE KEY TONE OFF/ON

To turn off the key tone, follow these steps.

1.  Turn off the scanner.
2.  While holding down L-OUT/S/S, turn on the scanner, OFF bEEP appears.

To turn the key tone back on, repeat these steps.  On bEEP appears.

TURNING THE BATTERY SAVE FUNCTION OFF/ON

To save battery power when a channel is manually selected or while you
program the scanner, the scanner automatically sets itself to a standby
battery (battery save) mode if no button is pressed for more than 5
seconds and no signal is received.  S appears when battery save is set to
on.

While the battery save mode is set to on, the scanner repeatedly turns off
the internal power for 1 second, then turns it back on for about 1/2
second to check for a transmission.

The scanner is preset with the battery save mode set to on, but you can
turn it off or back on.

Note:  The battery save mode does not work if the priority function is on,
       even if a channel is manually selected.

To turn the battery save function off or back on, turn off the scanner,
then hold down PRIORITY and turn on the scanner.

   OFF SAVE briefly appears when battery save has been turned off.

   On SAVE briefly appears when battery save has been turned on.

SKIPPING DATA SIGNALS

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

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

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.
