The CMS-15 Countermeasures Set consists of the following instruments and
accessories:
1) TD-53 Advanced Transmitter Detector
2) P-01 Wideband RF Probe
3) P-02 Infrared Probe
4) P-03 Line Driver
5) P-04 Carrier Current/Video Camera Probe
6) TT-46 Advanced Wiretap Detector
7) Headphones
8) Various cords, adaptors and Padded Carrying Case
Size: 3.75" x 5.5" x 2"
Weight: 10 oz.
Battery: 9 volt alkaline- Use only alkaline batteries- carbon/zinc batteries will not give
satisfactory performance.
Current: 25 mA average.
Audio Output: Up to 100 mW, internal speaker or headphones.
Indicators:
METER – 10 step LED – Each step represents a 3 dB change in signal strength.
AUDIO – In the DETECT mode, an audible "click" will be heard. The clicking rate will
increase as the signal strength increases. In the VERIFY mode, audio picked up by
the bug may be heard. As the bug is approached, a high pitched squealing tone will
be heard.
Controls:
VOLUME – In addition to acting as the on/off switch, this control is used to change
the audio output level.
SENSITIVITY – Normally left in HIGH. The LOW position reduces the sensitivity by
12 dB.
MODE – In the DETECT position, a "clicking sound" will be heard in the speaker. In
VERIFY position, a squeal is heard if the probe is near a transmitting bug.
EARPHONE JACK – For non-alerting listening, use with 4 to 2,000 Ohm
headphones.

Summary of Contents for Eddy Wireless CMS-15

  • Page 1 CMS-15 COUNTERMEASURES SET INSTRUCTION MANUAL The CMS-15 Countermeasures Set consists of the following instruments and accessories: 1) TD-53 Advanced Transmitter Detector 2) P-01 Wideband RF Probe 3) P-02 Infrared Probe 4) P-03 Line Driver 5) P-04 Carrier Current/Video Camera Probe...
  • Page 2 Probes: Several probes are available for the TD-53 that allows it to be used to locate several different types of bugs. Currently available probes are: P-01 - RF Probe, covers 5 MHz to 2.5 GHz. P-02 - Infrared Probe, detects IR and laser bugs. P-03 - Line Driver, detects hardwired microphones.
  • Page 3 In using the TD-53 to find a planted transmitter, turn the unit on and set the VOLUME so that you can hear the “clicks”. If you are in an area of high ambient RF (from radio or TV transmitters), you may have to set the SENSITIVITY switch to “LOW”. Walk slowly around the room while sweeping the probe (antenna) slowly up and down from ceiling to floor.
  • Page 4 Then, sweep around the phone and its lines while watching the meter and listening to the click rate. If these increase, hang up the phone. If they then decrease, you’ve got a pretty good clue that you need to do some more checking. At this point, you would conduct a physical search of the phone and phone line.
  • Page 5 a transmitter inside a refrigerator or metal file cabinet. All that steel would cut down the radiated signal. Just tape down the transmit button, turn the unit on and have someone hide it. Then practice finding the transmitter using both the DETECT and VERIFY modes. One disadvantage of the TD-53 is that the clicking (in the DETECT mode) or the squeal (in the VERIFY mode) can alert the eavesdropper that you’re on to him.
  • Page 6 When sweeping for IR transmitters pay particular attention to window openings – remember that light travels in a straight line. An unmodulated beam will cause the LED meter to read upscale and (in the Verify mode) a rushing noise will be heard in the speaker or headphone.
  • Page 7 GETTING STARTED On the P-03, set the LINE DRIVER/OFF switch to OFF. The A/B switch can be in either position. Plug the P-03 into the probe jack on the top end of the TD-53. Plug the headphones into the headphone jack on the side of the TD-53. FINDING MICROPHONES Detection of a concealed microphone and the L.P.
  • Page 8 working with the wire pair. CAUTION: If either an AC or DC voltage is indicated, DO NOT operate the DRIVER switch to the “LINE DRIVER” position. Turn up the TD-53 Volume control to a comfortable level and listen for room audio.
  • Page 9 Tune – Tunes through both of the above ranges from low to high. THEORY Carrier Current Transmitters, marketed as “wireless intercoms” and “wireless room monitors”, consist of a transmitter and sensitive microphone which intercepts room conversations and sends them along the power lines to a receiver. Very little signal radiates away from the power line.
  • Page 10 If you hear the sound source through the TD-53 in either of the above steps, there is a carrier current device operating on the line and you should try to locate it. To do so, try unplugging appliances and lamps one at a time. If the sound goes away once the cord is pulled on an item, you have located the transmitter.
  • Page 11 FINDING VIDEO CAMERAS To locate hidden video cameras with the P-04 use the following steps: Turn on the TD-53, set the MODE switch to “Verify” and the SENSITIVITY switch to “High”. Ignore any readings on the TD-53 LED meter. Set the P-04 RANGE switch to “10-130”...

  • Page 12: General Information

    Video cameras can be concealed in any number of places by using a pinhole lens. These cameras are very small and can be hidden almost anywhere and in almost anything. TT-46 GENERAL INFORMATION he TT-46 can detect both serie s and parallel wiretaps that are atta ched directly to the on premises telephone line.
  • Page 13 The following is a description of the functions of the switches and indicators on the TT-46. Please refer to your unit for their locations. MODE: Selects the type of test to be performed from the four below. PARALLEL: Checks for taps and bugs wired across the pair. Can detect resistances of 65 megohms or less.
  • Page 14 PARALLEL LED: Glows red if the Parallel test detects 65 megohms or less. Glows green if the test is OK. SERIES LED: Glows red if the Series test detects 10 ohms or more. Glows green if the test is OK. PUSH TO TEST: Use to apply the test to a wire pair in the Parallel, Series and Driver tests.
  • Page 15 WIRE PAIR VERIFY TEST In this test mode you will check the inside wiring for room audio that could be present if a microphone is attached to one of the wire pairs. Technically, this would not be a wiretap, but a bug. However, the result is the same – your confidential information is passed on to a listening post.
  • Page 16 3. At each connection point, push and release the PTT switch for each position on the Pair switch. Before leaving one connection point for the next, repeat the tests with the Test switch in the Test 2 position. 4. For each pair, the Series LED should glow green when the PTT switch is pressed.
  • Page 17 3. Press the PTT switch while lightly tapping the phone housing with a pen or pencil. If you hear the tapping in the TT-46 speaker, it is an indication that the phone is “hot on hook”. Release the PTT switch. 4.
  • Page 18 The hookswitch bypass can also be found by examination of the phone. The bypass will consist of one or more resistors, capacitors or diodes, usually connected to either the hookswitch assembly or network. Look for anything in the phone that doesn’t “fit in” or that seems out of place. Since phones are relatively inexpensive, you may want to replace a suspicious phone with a new one.
