4.3 RJ45 Network Test

  1. Extract the RJ45 remote unit as described in Section 3.2.
  2. Connect one end of the RJ45 cable to the main unit's RJ45 port and the other end to the remote unit's RJ45 port.
  3. Press the dB/RJ45 button (⑤) to enter network test mode.
  4. The display will show the wiring status (1-8 indicators) for continuity and correct pairing.

4.4 VFL (Visual Fault Locator)

The VFL function emits a visible red laser to help locate breaks, bends, or faulty connectors in fiber optic cables.

  1. Ensure the optical port is clean and connect the fiber to be tested.
  2. Press the VFL/LED button (②) to activate the VFL.
  3. Observe the fiber for red light leakage, which indicates a fault.

4.5 LED Lighting

For working in low-light conditions, the device includes an LED light.

  1. Press the VFL/LED button (②) to toggle the LED light on/off.
