TE-4200 Telephone Line Analyzer

The TE-4200 single line telephone analyzer incorporates many features to monitor the integrity of your phone line. This unit includes 3 visual status indicating L.E.D.s, a large easy to read 4.5 digit LCD display with low battery indicator icon, dual-tone alarm, 3 user function switches, and 2 threshold adjustment controls, and automatic mute circuitry.

The TE-4200 tests your phone line for slight voltage and current variations caused by possible parasitic R.F. radio transmitting devices, telephone repair line powered handsets, off hook extensions, or tampering of your phone line in your absence. This unit will digitally display your phone line voltage readings numerically both on and off hook, giving you a constant means of checking line integrity. In addition to the digital display, the Line Alert feature will monitor the phone line voltage when the phone is in use. If it detects changes, it will alarm you by lighting a red L.E.D. and alert tone.

The TE-4200 also contains a complete Near-field R.F. transmitter detection system capable of monitoring your phone line for possible illegal radio transmitting devices up to 1,000 feet from the source. It has a detection bandwidth of 1.495 Ghz and will detect transmitting devices from 5 Mhz to 1.5 Ghz. When it detects a transmitter, it will alarm you with a flashing L.E.D. and pulsing alert tone. The TE-4200 has a 3-way alert tone which allows you to distinguish the following types of alarm: R.F. only; Line Alert changes; the combination of both.

The TE-4200 safeguards your conversation with automatic mute circuitry if your line becomes compromised by an external line change. Only the phone plugged into the TE-4200 will go dead, preventing you from communicating any further until the line returns to normal. While you're away from the phone, the Monitor-mode will check your phone line for the tampering of wiring changes, open circuits, or a polarity reversal. When changes occur, the green L.E.D. indicator will turn on and flash indicating possible tampering and must be manually reset when you return.
