RHOTHETA Page 8 of 18 User Manual Direction Finder RHOTHETA RT-400 4 General Description The RHOTHETA direction finder system RT-400 is designed to receive and locate emergency signals and special application signals on the international distress and application specific frequencies in the VHF / UHF frequency range. The system consists of an RT-400 Antenna Unit (AU), which is designed light and robust for typical portable use, a RT-400 Carrying Frame, a RT-400 Power Pack, and the control software RT-400 DF Scout. The Power Pack can be charged using the RT-400 Battery Charger. The Antenna Unit can be installed on the optionally available RT-400 Car Mounting Kit. Besides the standard RT-400 Carrying Frame, the RT-400 Carrying Frame with lift can be used in cases where an easy reconfiguration from transport position to operational position is desired. The control software RT-400 DF Scout operates under Android operating systems on a tablet computer, which is connected to the Antenna Unit through a Wi-Fi connection. The RT-400 DF Scout is described in a separate User Manual. The RT-400 is a modern precision direction finder intended for professional SAR (search and rescue) purposes. It receives and locates signals on all international VHF-UHF emergency frequencies, including marine channel 16 and all COSPAS-SARSAT channels. The excellent performance of the RT-400 is possible due to our revolutionary patented wide band antenna and its sophisticated bearing analyzing algorithms, which deliver quick and steady information. Note In general, the RT-400 system is optimized for mobile and portable operation, where the heading of the control tablet computer and the antenna are identical. If the antenna is to be used in a fixed installation, make sure that the direction / north marking (marking on the Antenna Unit) points towards north. Refer to the DF Scout manual for setting up the software to operate without GPS and compass correction of the bearing rose. 5 Back Pack Operation without lift option 5.1 Installation in Transport Position For easy back pack transportation, the Antenna Unit may be installed upside-down on the carrying frame. The antenna is fixed using two quick clamps, with the antenna casing itself being resting on the padded platform. This carrying position, due to its low center of gravity, allows easier back-packed transportation of the system. The Power Pack is to be installed on the carrying frame. 5.2 Installation in Operating Position Place the Antenna Unit in Top-Up position. Make sure the direction marking (marking on the Antenna Unit) points into forward direction. The Antenna Unit should be placed as high as possible, or at least as high as needed so that the bottom part of the antenna cylinder is higher than the head of the person carrying the system. RHOTHETA Page 9 of 18 User Manual Direction Finder RHOTHETA RT-400 Connect the power cable from the Power Pack rack of the carrying frame to the connector at the bottom of the antenna mast. 5.3 Activation and use of the Antenna Unit The system is activated by toggling the POWER switch on the Power Pack to the ON position. Details on how to use the Tablet Software (RT-400 DF Scout) can be found in the RT-400 DF Scout User Manual. 5.4 Deactivation of the Antenna Unit The system is deactivated by toggling the POWER switch on the Power Pack to the OFF position. 6 Back Pack Operation with lift option 6.1 Installation Place the Antenna Unit in the Top-Up position and as low as possible (antenna part just above the padded ring, foot of the mast pressed in the lower ring) and fix it using the quick clamp. Make sure the direction marking (marking on the Antenna Unit) points into forward direction. Connect the power cable from the Power Pack rack of the carrying frame to the connector at the bottom of the antenna mast. Note Upside-down mounting of the Antenna Unit is only possible in the version without the lift option, and it is not possible in the lift version of the RT-400. 6.2 Activation and use of the Antenna Unit Drive the antenna to its operating position using the Up/Down switch on the Power Pack. The lift automatically stops when the maximum height is reached. The Antenna Unit should be placed as high as possible, or at least as high as needed so that the bottom part of the antenna cylinder is higher than the head of the person carrying the system. The system is activated by toggling the POWER switch on the Power Pack to the ON position. Details on how to use the Tablet Software (RT-400 DF Scout) can be found in the DF Scout User Manual. 6.3 Deactivation of the Antenna Unit The system is deactivated by toggling the POWER switch on the Power Pack to the OFF position. The Antenna Unit can be driven back to the transport position by pushing the Up / Down switch on the Power Pack DOWN. The lift automatically stops when the minimum height is reached. RHOTHETA Page 10 of 18 User Manual Direction Finder RHOTHETA RT-400 7 Mobile Use 7.1 Car Installation and Transport Position of the Antenna Unit The optional RT-400 Car Mounting Kit must be installed on the roof railing of the car first. The car mounting kit is prepared to be attached on standard roof luggage racks using tapped T-
heads Note Mounting technology might vary for some roof luggage racks. In the next step, fix the RT-400 Antenna Unit using the quick clamp. Make sure the direction marking (marking on the Antenna Unit) points towards the front side of the car. Pull the detent pin and move the antenna to the horizontal transport position and fix it with the included hook-and-loop tape. For non-operational road transport, the antenna should always be in this position. Connect the antenna to the power supply. The antenna may be powered through the external DC power cable connected to a car DC outlet (e.g. cigarette lighter connection). If using the DC power cable and feeding it through a door or window into the car, make sure not to crush the cable. The Tablet computer may be installed on the windshield using a car windshield tablet mount, or on any other position the operator finds appropriate. Connection to the Antenna Unit is through Wi-Fi, so no cable is needed. Warning Make sure the drivers visibility through the cars windshield and windows, and their access to control elements, are not obstructed. Note If using a car DC outlet to supply the Antenna Unit, depending on your vehicles electrical circuitry, the DC outlet might be interrupted under different conditions (ignition deactivated, etc.). Every interruption of the DC outlet will interrupt the operation of the Antenna Unit including the embedded Wi-Fi module. A later Wi-Fi reconnect to your Tablet computer might be delayed up to one minute or more, which is a normal behavior of Android operating systems. 7.2 Mobile Operation For bringing the Antenna to the operational position and operating the system while mounted on a car, release the hook-and-loop tape, pull the detent pin, and reposition the antenna unit vertically. Make sure that the detent pin has snapped in. Also, make sure that the NORTH marking on the antenna points towards the front of your car, otherwise, wrong bearings will be indicated in your RT-400 DF Scout application. Switch the power ON (Power switch on the RT-400 Power Pack or connecting the DC cable to the car DC outlet). Details on how to use the Tablet Software (RT-400 DF Scout) can be found in the DF Scout User Manual. RHOTHETA Page 11 of 18 User Manual Direction Finder RHOTHETA RT-400 8 Service and Maintenance of the RT-400 Power Pack 8.1 Installation of the Power Pack The power pack can be plugged into, and removed from, the power pack rack of the carrying frame. The power pack must be plugged into its rack as shown in the pictures above. As soon as the power pack is locked by the locking spring, it is automatically connected to the backward connector on the carrying frame and ready for use. To remove the power pack, pull the locking spring and unplug the power pack by pulling it forward. 8.2 Battery / Accumulator Replacement and Protection The Power Pack operates with an internal 14,4 V NiMH accumulator package. Use a Torx (size TX10) screw driver to remove the two screws on the back side of the Power Pack. The whole Battery Pack board can be removed from the housing and the accumulator may be replaced. All input- and output connections are fused: Charge Input (CHARGE, 4 A slow-blow), Antenna Unit Output (AU, 1 A slow-blow) and Lift Output (LIFT, 0,5 A slow-blow). Additionally, spare fuses are provided. RHOTHETA Page 12 of 18 User Manual Direction Finder RHOTHETA RT-400 8.3 Charging Accumulators Connecting the RT-400 Battery Charger directly to the Power Pack, instead of the Antenna Unit using the Power Cable, allows charging the accumulators. Charging is done automatically, so no further user interaction is required.

The information for which confidential treatment is sought is kept confidential by RHOTHETA International Inc. and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties:
To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure:
This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers Page 2 of 2

[Rev 1.00]
47CFR 15.121 Compliance Statement Coverage 1 This statement is valid for RHOTHETA receiver models designed in compliance to 47CFR Part 15 15.121, applying the same technological means of compliance, independent of their use in systems to be certified for marketing in the United States of America. Systems where these receivers are used are:
RT-400 RT-500-M RT-600 A RT-600 L RT-600 Light RT-800 RT-1000 A RT-1000 C RT-1000 Multichannel Compliance Statement 2 The equipment under application herein incorporates a scanning receiver, so 47CFR 15.121 applies. The equipment is incapable of operating (tuning) or being readily altered by the operator to operate within the frequency bands allocated to cellular radiotelephone service frequency bands (824 to 849 and 869 to 894 MHz). The equipment is also incapable of converting digital cellular transmissions to analog voice audio. Multi-stage frontend filters in SMD technology, including low-pass filters, high-pass filters and varactor-tuned band-pass filters under microcontroller control and with limited electrical tuning range cannot be altered to enable the receiver to scan the cellular radiotelephone service bands, especially not by means of clipping the leads of or installing diodes, resistors, jumpers or wires, or other simple component. The local oscillator circuitry, including low-pass filters, is under microcontroller control and cannot be altered to enable the receiver to scan the cellular radiotelephone service bands, especially not by means of clipping the leads of or installing diodes, resistors, jumpers or wires, or other simple component. Basic rejection of the cellular radiotelephone service bands by input filters is beyond the required measure of 38 dB (typical >80 dB for both filter stages). This is ensured by the physical design of filters. No plug-in semiconductor chips can be replaced, since no such chips are used. User entrance of receive frequencies in cellular radiotelephone service frequency bands is rejected by the firmware. No means are incorporated in the firmware to calculate internal receiver settings (filter, oscillator, etc.) for receive frequencies in the cellular radiotelephone service frequency bands. The microprocessor information is not accessible to the user. Without knowledge of processor information and circuitry, any attempt to modify the circuitry would render the equipment inoperable. Measurements according to industrial standards for AM and FM voice communication equipment under application of the 12 dB SINAD criteria with standard modulation (30% AM, 1 kHz and 3 kHz FM deviation, 1 kHz tone) as well as additional signal strength indication based measurement show spurious response rejections above 100 dB within cellular radiotelephone service frequency bands. In view of the above, the receiver complies with 15.121 of the Commission rules.
