Basic Countermeasures Equipment
2065 - RF DETECTOR (UNDER DESK MOUNTED)
The 2065 detects radio frequency (RF) transmitters which have been worn or carried to the vicinity of the desk. Covers the RF spectrum from 10 to over 1,000 MHZ. Meter indicates relative signal strength while a light emitting diode (LED) signals when the preset level has been exceeded. Unit is powered by a single 9-volt battery (Alkaline always preferred). System is supplied with detector and meter module, antenna, mounting screws and instructions. A matching tape recorder bias oscillator detector, the 2059D, is also available.
The 2065 is a sensitive, broad-band (1 to 2,000+ MHz) RF field strength indicator designed for under desk mounting. The unit is powered by a single 9 volt battery (Alkaline preferred) which provides a minimum of 500 hours of "ON" time. The 2065 system is supplied with detector module, wire antenna and mounting hardware.
INSTALLATION: Hold the 2065 in a position that can be viewed from the back of the desk and mark the location of the mounting hole with a pencil. Set the unit aside and insert the mounting screw in the place marked. Remove the screw and use it to mount the unit. Insert the antenna into the jack on the back of the unit.
Run the coaxial cable to the front edge of the desk and fasten the mounting bracket approximately 2 inches back from the edge. Roll out 3 to 4 feet of the fine wire antenna and tape it parallel to and about 1 inch back from the underneath front edge of the desk-top. Cut off the excess wire. Use a length of masking or carpet tape to hold the antenna wire in place.
The antenna is designed for use on wooden desks. If a metal desk is encountered it is necessary to fasten (using double sided sticky tape) a 1" by 1" by 3 to 4 foot length of wood under the front edge of the desk and then tape the antenna to it.
OPERATION: Test the battery by momentarily pressing the YELLOW switch downward to the BATTERY position. A reading of .8 or greater indicates a good battery. Place the switch in the DETECT position and rotate the GAIN control fully clockwise. The unit is now ready for use.
NOTE: If a very high RF environment is encountered it may be necessary to reduce the GAIN slightly to keep the meter at less than one quarter full scale. Bear in mind that the 2065 is a broad-band detector and will therefore indicate the presence of CB, taxi, or aircraft, transmitters. These types of transmitters can be identified by the fact that they are turned on and off fairly quickly. A surveillance device, on the other hand, emits a continuous signal. The small RED alert light will light when the meter reaches full scale.
ALWAYS TURN THE 2065 OFF WHEN NOT IN USE.
Note the initial mounting position of the battery before changing.
