User manual TRENDNET TC-TP1

[. . . ] Please observe and follow all safety protocols to avoid injuries. Description The Net Probe is a feature packed tone tracer. It is ergonomically designed to fit in the hand of the operator. The Probe can also accept a 2. 5mm earphone to help the operator listening to the tone in a noisy environment. [. . . ] Set the "TEL/TRACE" selector on the left hand side of the Probe to "TRACE?" position. Point the tip of the Probe to the cables that you are testing and push and hold the "TRACE" button to trace a line. You can also connect a RJ-11 or RJ-45 jumper cable from the Probe's RJ-45 jack to a wall jack to test its polarity. Tracing (for unknown cable path/termination) ­ Adjust gain (volume) control to the desired level and begin tracing from the tone generator location. Adjust the volume (gain) control to maintain a constant tone. Trace over the entire path of the test cable or until the cable end is located. Locating (termination verification/general area of termination) ­ Adjust gain (volume) control to the maximum level. Begin tracing in the general area of the cable termination. Zigzag the Probe slowly and exam the entire area. Avoid any high voltage sources and adjust the gain control when necessary to maintain a constant tone. i. ii. iii. Locating (conductor break/discontinuity) ­ Adjust gain (volume) control to "medium ~ low" level. Begin tracing the cable starting from the tone generator. 1 Continue tracing along the cable and when the tone disappear, the location of the Probe is where the cable break. Adjust the gain control to "high" level to pinpoint isolate the location of the break. Note: The tone is at its loudest when the tip of the probe is near and parallel to the cable carrying the tone signal. C. Line Testing Instruction Use this function on the compatible "Analogue" telecom and network system only. Set the "TEL/TRACE" selector to "?TEL" position. Connect the RJ-45 modular jack on the Net Probe to a wall jack using the jumper cable. Check the LED indicators under "TEL". i. Identifying telephone line polarity and verifying telephone line's function. ­ This LED lights green when the analog telephone patch cable or the outlet is installed properly. [. . . ] Tip Replacement (1) To replace Probe tip, grab the tip with your fingers and twist it counter clockwise until the tip comes off. (2) Replace old tip with a compatible new tip (included) and twist the tip clockwise until snug. Low battery indicator When the battery power is low, the "LOW BATT" LED will light red. Replace the old battery with a fresh one. [. . . ]
