## Summary description

LANBERG NT-0401 is a handheld UTP/STP cable tester for verifying RJ-11, RJ-12 and RJ-45 connections up to 250 m. It features LED status indicators, an on/off switch and operates from a single 9 V battery (not included). Compact and lightweight, it is suitable for network installation, troubleshooting and maintenance tasks.

## Long description

The Lanberg NT-0401 network cable tester is a compact multifunctional tool for verifying continuity and correct wiring of ICT cabling. Designed for UTP and STP (FTP, S/FTP) cables with RJ-45 plugs, telephone lines with RJ-11/RJ-12 plugs and coaxial-terminated wiring, the device helps identify shorts, open pairs and incorrect pairings. The kit includes the main tester unit with RJ-45, RJ-12/RJ-11 and coaxial connector LEDs and a separate terminator with RJ-45 and RJ-12/RJ-11 LEDs. Powered by a 9 V battery, the tester is suitable for field and rack-side checks in server rooms, offices and low-voltage installations.
Advantages
The tester provides separate pair-by-pair checking with two selectable speed modes (normal and slow), an automatic RJ-45/RJ-11 validation function and visible signal indication via 9 LEDs. It detects shield continuity when testing shielded cables and supports quick identification of faults in a variety of termination points such as switches, patch panels, sockets and devices. Its compact size and battery operation make it convenient for on-site use.
Suitable for
Testing UTP, FTP, S/FTP network cables terminated with RJ-45
Checking telephone lines terminated with RJ-11/RJ-12
Verifying coaxial connections
Field verification at switches, routers, PCs, patch panels and wall sockets
Low-voltage installations: CCTV, access control, fire alarm and cable TV networks
Key specifications

Power: 9 V battery
Dimensions: 102 x 28 x 105 mm (manufacturer data)
How to use
Connect one part of the tester to one end of the cable and attach the terminator to the opposite end. Select the desired speed mode (normal or slow) and switch on the tester. Observe the LED sequence to verify continuity, pair order and shielding. The device will indicate open wires, short-circuits and crossed or reversed pairs; for shielded cables check that the shield indicator shows correct continuity to the modular plug. For telephone or coaxial checks, use the corresponding connector on the tester and the terminator as required.
Usage recommendations
Use fresh 9 V batteries and ensure both tester parts are securely connected to the cable ends; avoid testing live mains-voltage lines. When diagnosing faults, start with the slow mode for clearer LED indication and verify suspected faulty segments at both ends and at intermediate patch points.
