Del Ray Suite A Alexandria, VA 22301 ORCA TM (Overboard Recovery Communications Apparatus) is a personal wa- ter-activated man overboard (MOB) alarm system developed by BriarTek Inc. The alarm system includes a signal de vice transmitter (TX100-base model), a receiving station (RX100-base model), and an optional direction finder (RDF). ORCA TM aids in the detection, location and recovery of individuals who be- come separated from the safety of their vessel, and thus exposed to the harsh elements of the sea. When the alarm is activated, ORCA TM transmits an initial FM message from the victim to the victim's shipboard receiver. The onboard alarm sounds upon receipt of a valid message. If the wearer of the transmitter does not disable the alarm within one (1) minute, the ORCA TM will begin transmitting an AM alerting signal th at can be received by standard SAR equipment including most types of RDFs. The ID data will be rebroadcast on average every minute. ORCA thus allows for a locally managed MOB situation ensuring that a victim is recovered quickly so as to minimize ef fects of exposure. Search and rescue (SAR) assets outfitted with direction fi nding equipment are capable of homing in on the 121.5 MHz emergency frequency to aid in a recovery effort. ORCA TM Special Features : • Capable of communicating with rescue authorities and other ships in the immediate area. • Uses patented technology to commun icate with the ship in an emer- gency. • Provides unique identification. • The RX100 can be used to determine how many sailors are in the water and in need of rescue. • Enables the user to signal “All Clear” to all receivers in the event of an inadvertent activation . • The TX100 has very low current consumption for longer battery life. • The TX100 uses standard 9 volt alkaline batteries. 1 WARRANTY INFORMATION WARRANTY INFORMATION Please detach and complete the following warranty information and mail to BriarTek Inc. at the address listed below.

Manual Activation/Test Button (ON)- Depress for test purposes to confirm the operability of ORCA ™ TX 100. B. Reset Button (OFF) - Depress to reset ORCA ™ from ‘Transmit Mode’ to ‘Armed Mode’. C. Water Sensors - Detects the presence of water in a man overboard situation. Keep clear of debris! D. LED/Antenna - Flashing LED confirms the transmission of emergency signal during a man overboard situation or during operational testing. Activation - Insert an alkaline 9-volt battery into the rear panel of ORCA  (all ORCA TM TX100s are shipped from the factory with new batteries in- stalled). This will automatically arm ORCA TM until activated through a man overboard situation or by depressing the ON button for manual activation or operational tests. Once activated, the LED will begin blinking to indicate it is transmitting an emergency signal. The emergency signal contains identifica-tion data tones to be decoded by the matc hing receiver, in addition to an ex- tended RDF transmission to aid in the location and recovery of the sailor over-board. Once the device is activated, the LED will flash on and off for approximately 10 seconds. Once the unit begins to transmit an alert it will turn on and stay on for at least a minute as th e unit transmits the alert and ID code to the receiver using FM mode. Once the ID codes have been sent the unit will transmit an audible tone in AM mode to allow RDF equipment an opportunity to locate the device. When the unit is transmitting in AM mode the LED will flash, and when the unit is transmitting in FM mode the LED will remain illuminated. 2 D ACB Figure 1. ORCA TM TX100 Deactivation - The OFF button should generally be used if the transmitter was unintentionally activated. DO NOT DEPRESS THE OFF BUTTON IF YOU HAVE FALLEN IN THE WATER. To deactivate ORCA TM , simply depress the OFF button for approximately one second. Continue depressing the OFF button until the LED powers off. NOTE - Deactivation resets ORCA TM to its armed mode until activated to …

INTRODUCTION The BriarTek, Inc. “ORCA” is a low-power Personal Locator Beacon intended to be attached to a Personal Flotation Device and used as an automatic alert of a man-overboard-occurrence and to locate personnel swept overboard in the event that he/she can no longer be tracked visually. The device is to be used to rescue personnel in close proximity of a vessel quickly; it is water-activated and signals a receiver installation on the vessel’s bridge to allow local search and rescue. The FCC granted a waiver for the ORCA (See Appendix A) that waives the requirements of 47 C.F.R. Para. 80.1053(a)(4) through (7), (a)(a4), (e) and 80.1055(a)(3), 80.1055(a)(4) and 80.1055(a)(3)(4). The ORCA transmits on 121.5 MHz with a rated ERP (dipole) of a nominal 5 milliwatts using FM modulation to transmit a time and unit identifier. Data on ERP(d), spurious emissions (Table 1) and occupied bandwidth (Figure 1) follow. PROCEDURES The field strength of the radiated emissions from the test sample was measured following ANSI 63.4 (1992) at a distance of 3 meters to the third harmonic at which time the horn antennas were moved to 1 meter. The spectrum was scanned from 30 MHz to the tenth harmonic using a Tektronix 494P spectrum analyzer. Measurement procedure included recording the worst-case field strength for receiving test antenna polarization, test antenna height variation from 1 meter to 3 meters and test sample rotation, and test sample antenna in both vertical and horizontal plane. The test sample was placed on a rotatable 80 cm high wooden stand. The receiving antenna, placed 3 meters from the test sample, were Compliance Design dipoles or EMCO 3115 Horns. RBW used on the TEK 494P was 100 kHz to 1 GHz; 1 MHz > 1 GHz. Peak responding detector, VBW = > than RBW. The device was operated from a battery supply enclosed in the EUT. The spectrum was checked from 30 to the tenth harmonic. All emissions not reported were less than 50 uV/m @ 3m or in system noise. Tabulation of the measurements are shown in Table 1.
