1. Four LEDs indicate the status on twisted pair cables. The top LED also
verifies continuity on Coax cables.
2. The "X" LED illuminates when testing a properly wired cross-over cable.
3. The "S" LED illuminates when a shielded data cable is properly connected at
both ends of the cable. It will flash if the shield is shorted to a wire in the cable.
4. The detachable remote is used to terminate the end of the cable being tested.
5. The SPLIT LED illuminates when the tester detects the signal is split between
two or more pairs.
6. The REVERSAL LED illuminates if the connections on a pair are reversed or
if two pairs are reversed with each other at one end of the cable.
7. The MISWIRE LED illuminates if there are misconnections between pairs.
8. The SHORT LED illuminates if two or more wires are shorted to each other.
9. The LOW BATT LED illuminates when the batteries are at the end of their life
cycle. When illuminated, the batteries should be replaced immediately.
Continued operation may result in inaccurate tests.
