4. Operating Instructions

4.1 Navigating the User Interface

The MAX-710B features an intuitive, icon-based graphical user interface (GUI) optimized for its 7-inch touchscreen. Use your finger or the provided stylus (3) to navigate menus, select options, and input data. The 'Home' button (9) allows quick access to the main application screen.

4.2 Performing an OTDR Test

1. Connect Fiber: Clean the fiber optic connector and connect it to the Singlemode OTDR port (1).
2. Select OTDR Application: From the main menu, tap the OTDR application icon.
3. Configure Test Parameters: The OTDR 2.0 environment offers automatic and real-time modes. For most standard tests, the auto mode will configure optimal parameters. You can manually adjust settings such as wavelength (1310nm or 1550nm), pulse width, and range if required.
4. Start Test: Tap the 'Start' button on the screen to initiate the OTDR trace. The Testing LED indicator (2) will illuminate.
5. Analyze Results: Once the test is complete, the OTDR trace will be displayed, showing events, losses, and reflections. The device includes automatic macrobend finders to assist in analysis.
6. Save Results: Save the test results for documentation and reporting.

4.3 Using Integrated Tools

• Visual Fault Locator (VFL): Activate the VFL from the menu to inject a red laser into the fiber for visual identification of breaks or macrobends over short distances.
• Power Meter: Use the integrated power meter (4) to measure optical power levels.
• Ethernet Tester: The device includes an Automated Ethernet Tester for 10/100/1000MB Ethernet network installation and optimization.

5. Maintenance

5.1 Cleaning the Unit

• Screen: Use a soft, lint-free cloth slightly dampened with water or a mild screen cleaner. Do not use abrasive cleaners or solvents.
• Casing: Wipe the exterior with a soft, damp cloth.
• Optical Ports: Always keep optical ports covered when not in use. Use specialized fiber optic cleaning tools (e.g., lint-free wipes, cleaning sticks, compressed air) to clean the OTDR port and VFL/power meter ports. Improper cleaning can damage the optical connectors.

5.2 Battery Care

• For optimal battery life, avoid fully discharging the battery frequently.
• Store the unit in a cool, dry place when not in use for extended periods.
• Use only the original EXFO-approved AC adapter for charging.

5.3 Software Updates

Periodically check the manufacturer's website for software updates to ensure optimal performance and access to new features. Follow the provided instructions for installing updates via USB or Ethernet connection.

6. Troubleshooting

6.1 Common Issues

• Unit does not power on: Ensure the battery is charged. Connect the AC adapter and attempt to power on. If the issue persists, contact support.
• Touchscreen unresponsive: Perform a soft reset by holding the power button for an extended period (e.g., 10-15 seconds) until the unit restarts. Ensure the screen is clean and dry.
• No OTDR trace or inaccurate readings:
  • Verify the fiber connection is clean and secure at the OTDR port.
  • Ensure the correct wavelength (1310nm/1550nm) is selected for the fiber type.
  • Check the fiber under test for severe damage or breaks using the VFL.
  • Ensure the test parameters (pulse width, range) are appropriate for the fiber length.
• Battery not charging: Verify the AC adapter is properly connected and the power outlet is functional. Check the AC adapter for damage.

6.2 Contacting Support

If troubleshooting steps do not resolve the issue, please contact EXFO technical support or your authorized distributor for further assistance. Provide your product model number (MAX-710B-SM1) and a detailed description of the problem.
