[. . . ] TC-TP1 Net Probe Amplified Inductor and Tone Probe User's Guide WARNING !Never connect this Probe to a live wire from a non-compatible telephone/network system. The Probe can also accept a 2. 5mm earphone to help the operator listening to the tone in a noisy environment. [. . . ] Connect a fresh 9V DC battery t the connector and slide the cover back to close the compartment. 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. 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. 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. 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. Connect the RJ-45 modular jack on the Net Probe to a wall jack using the jumper cable. 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. It indicates the telephone line carries proper voltage and has correct polarity. [. . . ] Low battery indicator When the battery power is low, the "LOW BATT" LED will light red. Battery Replacement (1) The Net Probe requires one standard Alkaline DC 9 volts or compatible battery. (2) Slide back the battery cover to replace the old battery with new one. SS112102 2 [. . . ]
