6. Setup

6.1 Battery Installation

1. Locate the battery compartment cover on the back of the main unit.
2. Slide the cover off to open the compartment.
3. Insert one 9V alkaline battery, observing the correct polarity (+/-).
4. Replace the battery compartment cover and ensure it clicks securely into place.

6.2 Connecting the Remote Module

For testing cables where both ends are accessible, the remote module can be attached directly to the main unit. For testing installed cables, detach the remote module by sliding it off the main unit.

7. Operating Instructions

7.1 Performing a Cable Test

1. Ensure the 9V battery is installed.
2. Connect one end of the cable to be tested to the appropriate port on the main unit (RJ45, RJ11, USB Type B, or BNC).
3. Connect the other end of the cable to the corresponding port on the remote module (RJ45, RJ11, USB Type A, or BNC terminator). If testing a BNC cable, use the provided BNC remote jack.
4. Press the 'Test' button located on the main unit.
5. Observe the LED indicators on the display panel to interpret the test results.

7.2 Interpreting LED Indicators

The LED display area provides visual feedback on the cable's condition:

• RJ-45 / RJ-11 / USB Indicators (Pins 1-8, S/C): These LEDs light up sequentially to indicate continuity for each wire.
• SHORT: Indicates a short circuit between two or more wires.
• CONNECTED: Indicates a proper connection for the corresponding wire.
• CROSSOVER: Indicates that wires are crossed, common in crossover Ethernet cables.
• NO CONNECTION: Indicates an open circuit or a broken wire.
• COAXIAL CABLE Indicators:
• SHORT: Short circuit detected in the coaxial cable.
• 25 Ω / 50 Ω: Indicates the impedance of the BNC terminator.
• NO TERMINATOR: No BNC terminator detected.
• BATTERY GOOD (Blue LED): Indicates sufficient battery power.
• BATTERY LOW (Red LED): Indicates that the battery needs replacement.

8. Maintenance

8.1 Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.

8.2 Battery Replacement

When the 'BATTERY LOW' LED illuminates, replace the 9V battery as described in Section 6.1. Remove the battery if the device will not be used for an extended period to prevent leakage.

9. Troubleshooting

• No LEDs light up: Check if the 9V battery is installed correctly and has sufficient charge. Replace the battery if necessary.
• Inconsistent readings: Ensure cables are fully seated in the ports. Check for visible damage to the cable or connectors.
• 'NO CONNECTION' for all wires: Verify that both ends of the cable are connected to the main unit and remote module, respectively. Ensure the cable itself is not severely damaged.
• Incorrect Crossover detection for RJ45: While the tester indicates continuity, it may not always detect swapped pairs (e.g., pins 7 and 8 swapped) as a 'crossover' fault. Visually inspect the wiring standard (T568A/B) if specific pinout verification is critical.
