TURNING MEMORY BANKS ON AND OFF

You can turn each memory bank on and off.  When you turn off a bank, the
scanner does not scan any of the 10 channels in that bank.

While scanning, press the number key that corresponds to the bank you want
to turn on or off.  When BANK appears, 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 so L/O appears.  You can
still manually select locked out channels.

To remove the lockout from a channel, manually select the channel and
press L-OUT so L/O disappears from the display.

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
channel in each bank as a priority channel (for up to a total of 10
priority channels).  If the priority feature is turned on, as the scanner
scans a bank, the scanner 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 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 1-2 for the channel in each bank you want to program as a
    priority channel.

To confirm all priority channel numbers, press PROG, then repeatedly press
PRIORITY to step through the priority channels.

To turn on the priority feature, press PRIORITY during scanning.  PRI
appears.

To turn off the priority feature, press PRIORITY again.  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, LOC OUt and P appear when you turn on the priority
        feature.

USING THE KEYLOCK

Once you set up and store channels into your scanner, you can protect it
from accidental changes by turning on the keylock feature.  When locked,
the only controls that operate are SCAN, MAN, KEYLOCK/(light symbol),
VOLUME, and SQUELCH.

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

CHANGING SEARCH SPEEDS

The PRO-74 has two search speeds.

      Normal Search                  Hypersearch

    100 steps/second               300 steps/second

To switch between normal and Hypersearch speeds, during a service bank or
direct search, press H/S.  HYPER appears during Hypersearch.

Notes:  You can use Hypersearch, only in the 5 kHz step bands (29-54 MHz
        and 137-174 MHz.

        Since the marine service bank is not in one of the 5 kHz step
        bands, you cannot use Hypersearch in the marine service bank.

TURNING THE KEY TONE OFF/ON

Your scanner comes set so each time you press a key, you hear a tone.  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
    for about 3 seconds.

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

TURNING THE BATTERY SAVE FUNCTION OFF/ON

To save battery power when a channel is manually selected or when you are
programming the scanner, the scanner has a battery save function which
automatically sets the scanner to a standby mode if no button is pressed
for 5 seconds when no signal is detected, and sets the scanner back to
full power mode when it detects a button press or receives a signal.  The
battery save function is set to on at the factory, but you can change it.
(S) appears when the function is active.

Note:  If priority is turned on, the battery save function does not work
       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/H/S and turn on the scanner.  OFF SAVE or on SAVE
briefly appears.

SKIPPING DATA SIGNALS

You can set the scanner so it skips nonmodulated or data signals (such as
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, press DATA.  DATA appears.  To turn off
the feature, press DATA again.  DATA disappears.
