6.2. Performing a Cable Test
- Connect the Cable: Plug one end of the network cable (RJ11 or RJ45) into the corresponding port on the Master unit and the other end into the Remote unit.
- Power On: Slide the Power Switch to the ON position. The Power LED will illuminate.
- Select Test Mode:
- Fast Mode: This is the default mode when powered on. LEDs will cycle quickly.
- Slow Mode: Short press the Power button to switch to Slow Mode. LEDs will cycle at a slower pace, allowing for more detailed observation.
- Manual Mode: Long press the Power button to enter Manual Mode. This allows for step-by-step testing.
- Observe Results: The LED indicators (1-8 and G for ground) on both the Master and Remote units will light up sequentially, indicating the status of each wire pair.

6.3. Interpreting LED Indicators
- Sequential Lighting (1-8, G): Indicates proper continuity for each wire.
- No Light: An open circuit (broken wire) for that specific wire.
- Incorrect Sequence/Multiple Lights: Indicates a cross-wire or split pair.
- Lights on both Master and Remote for a single wire: Indicates a short circuit.
6.4. Using the LED Light Assist
The Master unit features an integrated LED light to illuminate your working area, which is particularly useful in dimly lit environments. Activate it using the LED Switch.
