4. Operating Instructions
The PRO-652 uses object-oriented programming, which organizes frequencies and system parameters into "objects" for efficient management.
4.1. Basic Scanning
- Power On: Ensure the scanner is powered on.
- Select Scan Mode: Press the SCAN button to initiate scanning of programmed objects.
- Hold/Resume: Press HOLD to pause scanning on a specific frequency or object. Press SCAN again to resume.
- Volume and Squelch: Adjust the VOLUME knob for audio output and the SQUELCH knob to eliminate static noise between transmissions.
4.2. Programming Objects
Programming can be done manually via the scanner's menu or through computer software (sold separately).
- Access Menu: Press the MENU button to navigate the programming options.
- Create New Object: Select the option to create a new object (e.g., conventional channel, trunked system talkgroup).
- Enter Parameters: Input the frequency, mode (AM/FM/Digital), and other relevant parameters for the object.
- Assign to Scanlist/Folder: Organize objects into scanlists or V-scanner folders for efficient scanning.
- Save: Ensure all changes are saved before exiting the programming menu.
For detailed programming instructions, refer to the full user guide available on the RadioShack support website. Computer programming software and cable are recommended for advanced users.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the scanner. Do not use liquid cleaners or solvents.

- Storage: When not in use for extended periods, store the scanner in a cool, dry place, away from direct sunlight and extreme temperatures.
- Power Supply: Only use the supplied AC adapter or a compatible replacement.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | No power connection or faulty adapter. | Check AC adapter connection to scanner and wall outlet. Ensure outlet is functional. |
| No audio or weak audio. | Volume too low, squelch too high, or no active transmissions. | Increase volume. Decrease squelch. Verify programmed frequencies are active. |
| Poor reception or static. | Antenna issue, interference, or weak signal. | Check antenna connection. Relocate scanner away from interference sources. Consider an external antenna. |
| Difficulty programming channels. | Incorrect programming steps or unfamiliarity with object-oriented system. | Review the operating instructions for programming. Consider using computer software for easier programming. |
