GETTING STARTED

Battery Installation

Loosen the screw on the battery compartment cover, remove it, and snap in a 9-volt battery (Radio Shack recommends 23-553 or equivalent). This battery backs up the scanner's memory during power outages. Replace the battery every six months for best results.

When the memory backup battery is weak or disconnected, the display shows BATT and an alarm beep sounds.

CAUTION: To avoid loss of programmed data, do not unplug the power cable while replacing the battery. Never leave a weak or dead battery in the unit, as it can leak damaging chemicals.

AC Power Operation

Connect the AC power cord to a standard AC outlet.

Car Battery Operation

The PRO-2004 can be operated from a 12-volt, negative ground vehicle battery using an optional DC power cable (Cat. No. 270-1534). Connect the cable to the DC13.8V jack and then to the vehicle's cigarette lighter socket.

Caution: Ensure the power cable does not touch metal parts in the vehicle. Connect the plug to the unit's jack before connecting to the cigarette lighter socket.

Antenna

Attach the telescopic antenna to the ANT connector, aligning the protrusion with the notch and securing it. Antenna length affects sensitivity; adjust as follows:

• 25 MHz – 300 MHz: Extend fully.
• 300 MHz – 520 MHz: Extend 3 segments.
• 760 MHz – 1300 MHz: Collapse fully (one segment only).

For optimal reception, use an external antenna. Radio Shack offers suitable antennas and mounting hardware.

WARNING: Exercise extreme caution when installing or removing outdoor antennas. If an antenna falls, let it go to avoid contact with power lines, which can cause electrocution. Contact the power company to remove a fallen antenna.

RESTART Switch

If the LCD display or any key function becomes erratic, press the RESTART switch with a ball-point pen. This will clear the current frequency and revert the unit to its initial mode, with some functions returning to their default settings (Priority: Channel 1, Monitor: Channel 1, Search Bank: Bank 1, Scan Bank: All on).

OPERATING YOUR PRO-2004

Turn on the PRO-2004 by rotating the OFF/VOLUME control clockwise. Adjust SQUELCH until the background noise stops while scanning resumes.

Understanding the Display and Keyboard

The LCD displays channel number, frequency, function status (delay, locked out), and operation mode. The keyboard is used for all programming and control functions.

TAPE Out

Connect a tape recorder to the TAPE OUT jack to record received signals.

BATT Indicator

When the memory backup battery is low, the [BATT] indicator appears, and an alarm beep sounds. Replace the battery promptly.

• The scanner automatically rounds entered frequencies to the closest valid frequency based on the selected step (5 kHz or 12.5 kHz).
• The tuning range is fixed and cannot be altered.
• To change a stored frequency, simply enter the new frequency over the old one.

Manual Mode

In MANUAL mode, you can manually advance through programmed channels by repeatedly pressing the MANUAL key or directly access a channel by entering its number and pressing MANUAL. Locked-out channels or skipped banks can be accessed in manual mode.

Scanning Frequencies

The PRO-2004 automatically scans programmed channels, stopping when a signal is detected. Ensure SQUELCH is adjusted correctly to prevent continuous noise. Press MANUAL to stop scanning and select a specific channel.

Delay

Press the DELAY key to hold a channel for at least two seconds after a transmission ends, allowing you to hear both sides of a conversation. The DELAY indicator appears on the LCD. Press DELAY again to cancel.

Forced Scan

If scanning stops due to a signal, press SCAN to resume scanning immediately.

Speed Selection

Press the SPEED key to alternate between fast (16 channels/sec) and slow (8 channels/sec) scanning rates.

Locking Out Frequencies (Skipping Frequencies)

To skip channels during scanning:

1. Press MANUAL to stop scanning.
2. Navigate to the channel to be locked out.
3. Press LOCK-OUT. The LOCK-OUT indicator appears.

To cancel lockout, repeat the process or use the LOCK-OUT REVIEW function.

Note: The last channel in a bank cannot be locked out, and each bank must have at least one non-locked-out channel.

Skipping Banks

To skip entire banks during scanning, press the corresponding bank number key (1-10, with '0' for bank 10) while in SCAN mode. The bank number indicator will disappear. Press the key again to restore the bank.

Priority

The PRO-2004 can monitor other channels while automatically switching to a designated priority channel when a signal is detected. Channel 1 is the default priority channel.

Programming the Priority Channel: Press PROGRAM, enter the desired channel number, and press PRI. The 'P' indicator confirms the priority channel. Press PRI again to revert.

Using Priority: Press PRI in scan or manual mode. The PRIORITY indicator appears. The receiver checks the priority channel and switches to it if a signal is present. Press PRI again to cancel.

Note: All settings (delay, lockout, speed, priority, step, skipped banks) are retained when the power is turned off.

SEARCHING WITH YOUR PRO-2004

Limit Search

To search within a specific frequency range:

1. Press PROGRAM.
