If you suspect your premises are bugged, for your own peace of mind, check it out. The TD-53 can be used to detect, verify and locate hidden transmitters in your home, office or car. P-02 INFRARED (IR) PROBE
Use the TD-53 to perform a professional RF sweep of your premises, including your telephone system. Similar in operation to a Geiger counter, the sensitive antenna system can be used to probe all areas of a room. As the antenna approaches the hidden transmitter, the audible tone clicks faster and faster while the ten step solid-state meter indicates the signal strength.
At this point, switch modes from Detect to Verify to differentiate a bug from a regular radio or TV transmission. If a bugging device is present, a continuous squealing tone is generated by the TD-53. By sweeping the probe, this tone can lead you directly to the bug. The switch selectable SENSITIVITY level improves detection capabilities of the unit in high signal strength areas. For private (non-alerting) listening, an earphone jack is provided.
Included with the TD-53 is the P-01 wideband active probe which covers 5 MHz to 2,500 MHz. The P-01 can be positioned up to 25 feet away from the TD-53 by using an extension cable. For example, the probe could be discreetly placed in a target room while the TD-53 is monitored in another room. Several other plug-in probes are available which will extend the usefulness of your TD-53 (see the next two pages). The unit measures 5.8" x 3.4" x 2" (with cover closed) and weights 9 oz. It is powered by one 9 volt alkaline battery (included). Also included is an illustrated instruction manual.
OPTIONAL TD-53 ACCESSORY PROBES (These Probes must be used with a TD-53)
Light beams, especially lasers, provide an excellent method for carrying audio intelligence and are not detectable by RF (radio frequency) detectors. The P-02 is a special probe which allows you to search for sources of infrared (IR) transmissions. In the case of amplitude modulated or pulse frequency modulated sources, you can actually listen and determine if the IR beam is carrying voice or other intelligence.
P-03 LINE DRIVER
The P-03 Line Driver Probe lets you use the TD-53 for checking wire pairs for hidden microphones. One of the two LEDs on the P-03 alerts you to the presence of voltage on a wire pair. The other LED alerts you to current flow in a wire pair when the Line Driver switch is operated.
The Line Driver switch applies a voltage to the wire pair under test to turn on voltage activated microphones. The A/B switch reverses the polarity of the voltage for detecting polarity sensitive devices. You can also monitor the wire pair through the TD-53 amplifier and speaker to determine if room audio is present on the pair. Any of the above conditions can indicate a microphone attached to the wire pair under test.
P-04 CARRIER CURRENT/VIDEO CAMERA PROBE
The P-04 is used in conjunction with the TD-53 for detecting carrier current transmitters and concealed video cameras. Examples of carrier current transmitters are the wireless intercoms and room monitors sold in many electronics stores and catalogs. Carrier current eavesdropping devices can be connected to power lines, phone lines or other wire pairs. The probe covers from 10 KHz to 600 KHz in two ranges. It uses a directional pickup loop and no connection to the power lines or other wires under test is necessary. Any demodulated audio is fed to the TD-53 for monitoring and verification purposes.
Please call for optional probes.
