Sniffer Sleuth User’s Manual Introducing Sniffer Sleuth Sleuth is a hand-held signal leakage detection device. When programmed, Sleuth makes active measurements on a chosen frequency and shows the results on a liquid crystal display (LCD). It indicates detected leakage by receiving and processing a modulated carrier.

Sniffer Sleuth User’s Manual Introducing Sniffer Sleuth The Sleuth “panel” is equipped with two keys. The ON / OFF button turns Sleuth on and off. The FUNCTION button switches the Sleuth from its normal, or operating, mode into one of the Setup modes. Repeated presses of the FUNCTION button scroll through each of the different setup functions and then back to the operating mode.
Sniffer Sleuth User’s Manual Setup Function Modes: Mute Sleuth powers up in its operating mode, allowing you to instantly begin to make measurements. There are seven additional “Setup” function modes: Mute, Loudness, Distance, Squelch, Battery, Frequency, and External Antenna, which you can use to change Sleuth’s operating parameters. In each of these modes, Setup is highlighted, as well as the particular setup function;...
Sniffer Sleuth User’s Manual Setup Function Modes: Loudness The Loudness mode allows adjusting of Sleuth’s speaker volume. To access this function, turn Sleuth on; after the self-test, press the FUNCTION button until Loudness is flashing. To change the loudness, press the rocker switch down to decrease loudness; press the rocker switch up to increase loudness.
Sniffer Sleuth User’s Manual Setup Function Modes: Distance The Distance mode allows adjusting of Sleuth’s readout over different operating ranges. A strong reading made at a distance of ten feet would be significantly attenuated if made at 150 feet. When the distance setting is adjusted.
Sniffer Sleuth User’s Manual Setup Function Modes: Squelch The Squelch mode allows adjusting of Sleuth’s squelch threshold. To access this function, turn Sleuth on; after the self-test, press the FUNCTION button until Squelch is flashing. To change the squelch threshold, press the rocker switch down to decrease the threshold level; press the rocker switch up to increase the threshold level.
Sniffer Sleuth User’s Manual Setup Function Modes: Battery The Battery mode displays Sleuth’s battery level. To access this function, turn Sleuth ON; after the self-test, press the FUNCTION button until Battery is flashing. The Relative Indicator remains active in this mode, displaying the relative battery level.
Sniffer Sleuth User’s Manual Setup Function Modes: Frequency Allows adjusting of Sleuth’s target frequency. To access this function, turn Sleuth ON; after the self-test, press the FUNCTION button until Frequency is flashing. The Distance indicator now reads the previously-set target frequency, followed by MHz instead of Ft.

Sniffer Sleuth User’s Manual Setup Function Modes: Frequency Press FUNCTION again to exit the Frequency mode; this will occur automatically after 5 seconds. NOTE: the model’s frequency range limits how far the frequency can be adjusted in any direction. For instance, on a unit already set to 121.2255, pressing down will yield no results, as “111.2255”...
Sniffer Sleuth User’s Manual Setup Function Modes: External Antenna When Sleuth is turned on (and not housed in the Docking Station), it always defaults to using the internal dipole. However, this mode allows switching of the Sleuth’s antenna from the internal dipole to an external hand-held dipole antenna.

Sniffer Sleuth User’s Manual Using Sleuth in the Field Sleuth is in its operating (normal) mode after it’s turned on and performs a brief self-test. Before turning on Sleuth for field use, make sure the battery is fully charged, and make any user-preference changes that aren’t likely to change during field use - e.g., target frequency, mute, and squelch.
Sniffer Sleuth User’s Manual Using Sleuth in the Field On Sleuth’s LCD, the µV/m indicator displays the intensity of the signal it is detecting relative to the distance range selected (see Setup Function Modes: Distance). The relative indicator displays the intensity of the detected signal at ±10 dB from the selected sensitivity reference, which can be...
Sniffer Sleuth User’s Manual Using Sleuth with the Docking Station The Docking Station is designed to allow Sleuth to be easily used in a vehicle. It provides a stable platform for holding Sleuth so that the buttons and LCD can be easily seen, and extends battery time by connecting the Sleuth to the vehicle’s power supply.

Sniffer Sleuth User’s Manual Using Sleuth with an External Antenna Sleuth can also be used with a handheld external dipole antenna by means of an external antenna adapter (part #100892-001). To use, mount the adapter into the antenna port on the front of the Sleuth unit, then attach the external antenna’s cable to the adapter.
Sniffer Sleuth User’s Manual Charging the Battery Sleuth uses a 9.6V nickel-cadmium (NiCad) battery housed within the handle. Everyday use of the battery and recharging will eventually require its replacement. To replace the Sleuth battery, remove the screw (see below) holding the battery compartment door in place.
Sniffer Sleuth User’s Manual Appendix A: Adjusting the Dipole Antenna Optimum antenna lengths for the dipole are given for possible Sleuth frequencies in the table below. Model 100760-001 (80 MHz ~ 120 MHz) Model 100760-002 (120 ~ 150 MHz) Frequency...
