---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- This tester is a simple yet powerful tool that helps troubleshoot breaks and cross connections in network and telephone cables. The tester consists of a main master unit and a detachable remote unit, each with an RJ11 jack and an RJ45 jack The unit is powered by a 9-volt power supply and comes with a zippered synthetic leather case. The master and remote units each have a series of nine LEDs that indicate the status of each line in the connected cable. The tester supports both fast and slow automatic modes. Streamlined shape and ergonomic design. Drop-proof, light-resistant, suitable for on-site construction. specification Size: Approx. 105x105x26mm / 4.1x4.1x1.0in Weight approx. 200g/7.1oz Power supply: DC9V laminated battery sold separately Testing Methodology 1. For twisted pairs 1, 2, 3, 4, 5, 6, 7, 8, G, test each pair one by one to determine which pair has a wrong line, short circuit, or open circuit. 2. Switch OFF to close, ON to normal test speed, S to slow test speed 3.Twisted pair test Turn on the power supply and connect the network cable plug to the main tester and remote tester respectively. The host indicator light flashes from 1 to G in sequence.

If multiple lines are not connected, some lines will not be bright. If there are less than two lines connected, the light will not be bright. c. If both ends of the network are faulty, examples 2 and 4 fail. Main tester unchanged 1-2-3-4-5-6-7-8-g The remote test terminals are as follows: 1-4-3-2-5-6-7-8-g d. If there are two short circuits in the network line, the main tester display will not light up, and the two line lights indicating the short circuit in the remote test terminal will be slightly bright. If there are three or more, including three, all short circuit lights will be dark. Package List 1 x Cable Tester 1x storage bag
