TCM-03 is a sophisticated and operationally flexible cable checking system used to test room cables and wiring for evidence of bugging devices.

TCM-03 combines the following features:

• Highly sensitive audio frequency amplifier

• Tuneable low frequency radio receiver

• Digital display meter

• Integral tone generator

• Isolated DC power output.

These provide an armoury of tools for assisting in detection of microphone and other bugging signals at levels from microvolts to volts on all types of cable including AC and DC power cables and telephone lines.
