To clean, wipe the case with a damp cloth and detergent (do not use
abrasives or solvents).
When the power LED does not light when the unit is switched on, you need to replace
the battery. The terminator does not use a battery.

The tester is powered by a single standard or alkaline 9V battery. Use the
following procedure to replace the battery.
1. Disconnect the cables from the tester.
2. Open the battery cover, carefully remove the old battery, and replace
with a new battery.
3. Reinsert the battery into the case, dressing the battery leads so that

OPERATION INSTRUCTIONS
Warning:
1. Caution: Do not connect the cable tester to live circuits as it may be
damaged by over voltage.
2. Turn on the TCT-355. If the power light ( O ) does not light, please
replace the 9V battery with a new one.
3. When testing communication cable with RJ11 connectors, use only
the RJ11 jacks on the tester and remote.
How to Use the TCT-355:
1. Turn on the power switch, the power light will flash (“S” for low speed
test).
2. To test communication cable, connect an end of the cable to the tester
and the other end of the cable to the remote.
3. The LED’s will light in sequence 1 - G on the tester. Check that the
correct corresponding LED lights on the remote unit per your wiring
configuration. A short is indicated by no LED’s lighting on the remote.
An open wire/shield by no LED’s lighting on the tester and remote.
4. To test a coaxial cable, connect one end of the coaxial cable to the
connector on the tester and connect a terminator to the other end. If
the cable is good, the TCT-355 indicator light “B” will be lit green and
the terminator LED will be lit. If the light does not turn on, the cable
has an open connection or short.
CAUTION
DO NOT test cable connected to electric power. To avoid electric
shock, disconnect the power to the cable under test. Connection to
an active power cable can result in injury or even death.
