Maintenance
Warning
• Turn off the Toner or Probe and disconnect all test leads before replacing the battery.
Caution
• To avoid damaging the case, do not use solvents or abrasive cleansers.
• Clean the case with a soft cloth dampened with water or a mild soap solution.
Trouble shooting
• If the MT-7068 Probe volume is too low when using the 1KHz signal to validate and isolate electric wires:
1. Check to see that the Probe rotary switch is properly positioned and that there is no low battery
indication.
2. Turn the Probe volume to Maximum.
3. Check to ensure the Toner rotary switch is properly positioned and that there is no low battery
indication.
4. Check if the Toner black alligator clip is connected to the ground and the red alligator clip is properly
connected to the testing wire, the adapter or the patch panel.
• If the light displays incorrectly when using the CABLE MAP to test:
1. Re-check that the Toner and Probe rotary switches are properly positioned and that there is no low
battery indication.
2. Use the RJ-45(8Pin) to RJ-45(8Pin) patch cord that provided with the package to run a simulated test.
3. Connect the testing wire with both end connectors and then reconnect it properly.
