PSW-SS2001Bite indicator for fishing

PROGRAMMING YOUR SYSTEM Open the battery compart- ments on the pager and transmitters. Locate the digital code panel (DIP switch) in each unit. Carefully slide the 8 switches up or down to form a pattern which will be your own personal code. (Example: 4 up and 4 down). NOTE: Be sure to code your pager and all your trans- mitters with the same pattern. ATTACHING THE TRANSMITTER Attach one of the enclosed velcro strips to the bottom of the transmitter. Place the other velcro strip on the tip-up and attach the transmitter to it. Refer to the illustrations (below left) for the proper position in which to place the velcro for each style tip-up used. Surfaces must be room temperature and dry. Tie one end of the string to the metal clip (included). Attach the metal clip to your tip-up flag while in the set position. Leaving a small amount of slack in the string, measure and tie the other end to the transmitter trip key. BASIC USE Attach the transmitter to a set tip-up. Insert the trip key into the slot on the top of the transmitter and clip the other end to the flag. Switch the transmitter “ON” and extend the antenna. Switch the pager unit “ON” and press “RESET”. Your system is now active. TESTING THE PAGER BATTERY The pager is equipped with a battery tester. To test, press and hold the “RESET” button. A sharp, continuous “BEEEEP” indicates a good battery. A weak, intermittent “beep, beep, beep” indicates a weak battery which should be replaced. To prolong battery life, be sure units are turned off when not in use. EFFECTIVE RANGE AND TRANSMISSION DISTANCE Strike Sensor works on a powerful FM radio signal that has worked in tests up to 650 feet. Your reception distance will vary depending upon atmos- pheric conditions. For optimal range, the area between the pager and transmitters should be unobstructed and in a direct line of sight. The pager antenna wire must be straight up.Carry the pager with the antenna outside your clothing in a chest pocket or as high as possible. The higher the pager is elevated from the transmitters, the better the reception.When fishing from a metal shanty or lake cot- tage, place the pager in a window facing the transmitters. Precipitation can reduce range. NOTE: Avoid condensation in the units. After each outing, bring units indoors. Clean well, and store in a dry place. FCC COMPLIANCE This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable pro- tection against harmful interference in residential installation. This equip- ment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna • Increase the separation between the equipment and receiver • Connect the equipment to an outlet on a circuit different from that to which the receiver is connected • Consult the dealer or an experienced radio/TV technician for help Changes or modifications not expressly approved by SensorTronics, Inc., can void the user’s authority to operate the equipment. BATTERY INSTALLATION Install a 9 volt battery in the pager and transmitters as the diagram in the battery compartments illustrate. Be sure all battery connections fit tightly. In the transmitter, coil excess wire immediately in front of the battery, making sure there is no wire above or below the battery itself. Wire from the battery to the DIP switch compartment should be tucked into the crack along side the compartment divider. Note: For optimum cold weather operation, always use alkaline or lithium batteries. The pager can also be powered using an optional AC or DC adapter. The AC/DC adapter plugs into the jack on the side of the pager. These adapters will override an installed battery and are readily available in the electronics department of most stores. Adapters with an output of 9V DC 500mA are recommended. Any number of transmitters can be coded to activate a single pager.

The trigger mechanism, when actuated, turns on the power to the transmitter. As the transmitter is triggered, it begins transmission of the coded packets. The receiver, carried by the user, then activates the light and sound indicators, in a latched fashion. The user, at this point, deactivates the transmitter, which will shut off within 25 milliseconds of deactivation by the user. The transmitter also has a watchdog timer that will time-out before 5 seconds, and stop transmission via the transmit-enable pin. This limits the total transmission to less than the allowed 5 seconds. The receiver will continuously run the light and sound alarm indicators to alert the user. The light and sound indicators on the receiver can only be reset after the transmitter is deactivated. After the transmitter is deactivated, the receiver can be restored into normal operation with the alarm reset switch. Multiple transmitters may be used with one receiver. Each transmitter has an on-board light indicator, that can easily identify which of the transmitters have been activated in the multi-transmitter setting. The user, ice fishermen, would typically be in close proximity, within 300 feet of the activated transmitter, and can quickly attend to the transmitter. The environment of use would typically be on a frozen lake. L.S. Research Inc. W66 N220 Commerce Court Cedarburg, WI 53012 Phone 414.375.4400 Fax 414.375.4248

Dear Jim, We have the following issues to resolve on this one. 1. The label is made out of paper. The FCC does not allow paper because their interpretation is that it cannot meet the requirement to "last the expected lifetime of the product". Please provide an alternate material such as mylar. Response - Boyd Stoffel will be contacting his label maker to develop a label out of Mylar type material. 2. I am checking with the FCC to see if fish activation qualifies as "manually activated". Response - The product has now been modified to time out after 4 seconds. This modification now brings the transmitter in compliance with the FCC rules. Please find attached the following: Updated Theory of Operation Updated Schematic with the RC change. Updated photo supporting the modification and updated screen capture showing the time out of the transmitter. 3. Please describe the units method of antenna attachment with regard to the requirements of 15.203. Response - The antenna is attached to the PCB by a screw to lock it down. The only way to access this screw is to disassemble the product and physically remove it. See Photo 6, lower left corner. This is a notched area for the antenna to screwed on to. Also see Photo 5, showing the antenna removed. The end of this antenna is a screw down connection. 4. Please confirm that the label is on a permanent part of the device and not on a removable cover. Response - Please see Photo 1, showing the label attached to the top of the case. The removable battery door is on the bottom of the case. Therefore, the label is located in an area that is permanent. Best regards Barry C.

L. S. COMPLIANCE, Inc. FCC ID: PSW-SS2001 LSC-Strike Sensor 301245 Page 6 of 30 1.5INTRODUCTION On July 25 th , 2001, August 8 th , and 10 th , 2001, a series of radiated emissions tests were performed on one sample model of the Strike Sensor transmitter, a small handheld sensor unit, which is designed to transmit a coded signal used in a wireless application. These tests were performed using the test procedures outlined in ANSI C63.4-2000 for intentional radiators, and in accordance with the limits set forth in FCC Part 15.231b for a periodic transmitter. These tests were performed by Thomas T. Lee, of L. S. Compliance, Inc. and witnessed by Kenneth Boston, PE, of L.S.Compliance, Inc. 1.6PURPOSE The above mentioned tests were performed in order to determine the compliance of the Strike Sensor transmitter with limits contained in various provisions of Title 47 CFR, FCC Part 15, including: 15.10915.231b 15.20515.231c 15.209 All radiated emissions tests were performed to measure the emissions in the frequency bands described by the above sections, and to determine whether said emissions are below the limits established by the above sections. These tests were performed in accordance with the procedure described in the American National Standard for methods of measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (ANSI C63.4-2000). Another document used as reference for the EMI receiver specification was the International Special Committee on Radio Interference (CISPR) number 16-1 (1993). 1.7RADIATED EMISSIONS TEST SETUP The test sample was operated within the 3 meter Semi-Anechoic, FCC listed chamber located at L.S. Compliance in Cedarburg, WI. The sample was placed on an 80cm high wooden pedestal, which was centered on the flush-mounted 2m diameter metal turntable. The test sample was operated on its own [new] internal battery. The battery voltage at the beginning of the tests was measured to be 9 volts. The test sample was configured to run in a continuous transmit mode during the 15.231c and 15.231b measurements. Please refer to Section 1.11 for pictures of the test setup. L. S. COMPLIANCE, Inc. FCC ID: PSW-SS2001 LSC-Strike Sensor 301245 Page 7 of 30 1.8RADIATED EMISSION TEST PROCEDURE The fundamental and spurious (harmonic) emissions of the transmitter was tested for compliance to Title 47 CFR, FCC Part 15.231b limits for periodic devices. For the calculations used to determine the limits applicable for the test sample (at their respective operating frequencies) refer to Appendix A. These limits are expressed in decibels (dB) above 1 microvolt per meter (μV/m). The sample was tested from the lowest frequency generated by the transmitter (without going below 9 kHz) to the 10th harmonic of the fundamental frequency generated by the device. The appropriate limits were also observed when the fundamental or spurious signals were located within any of the restricted bands as described in Part 15.205a. These frequencies, and their associated limits, are referenced in Section 1.10. The sample was placed on a nonconductive (wooden) pedestal in the 3 Meter chamber and the antenna mast was placed such that the antenna was 3m from the test object. A biconical antenna or tuned dipole was used to measure emissions from 30 to 300 MHz, a log periodic or tuned dipole …
