Your activity info is available at a glance without turning your wrist, pressing buttons, or breaking stride. Strap your FS-1 to your wrist with the buttons pointing up from the top of your wrist. 2 WATCH BUTTONS Button functions listed in normal font (MODE, SELECT, LIGHT, SPLIT, START/STOP) are performed by pressing and releasing the button. BUTTON FUNCTIONS MODE Cycles through the seven main modes. If you stay in any mode for more than three seconds, the title screen will disappear and the mode content screen will appear. The next press of the MODE button will return you to TIME mode. SELECT Toggles between "pace display" and "speed display" in SPED mode. Toggles between track and treadmill calibration in CALB mode. Accepts selected values and advances to next field while setting. LIGHT Turns on the light for 3 seconds. Holding LIGHT for 3 seconds turns on Night Mode. In Night Mode, pressing any button will turn on the light for 5 seconds. Holding LIGHT for 3 seconds turns off Night Mode. SPLIT In SPED mode, with the chronograph running, SPLIT freezes the screen and records a manual split in the daily chart. Holding for 3 seconds in TIME mode launches COMM mode. 3 The FS-1 foot pod may be placed on either your right or left foot. The stride characteristics of your right leg may be different from those of your left leg. Always keep the foot pod on the same foot. START Starts and stops the chronograph in SPED mode. /STOP Button functions listed in reverse font (SET , RESET) are performed by pressing and holding the button for 3 seconds. SET Hold SET in TIME mode to change time. Hold SET in SPED mode to set weight, view alert interval and toggle Pace Zones ON and OFF. Hold SET in ALRM mode to change alarm settings. RESET Hold RESET in SPED mode to store activity in your log and clear the display. Hold RESET in SPED mode when the chronograph is zeroed to enter the LOG clear menu. Hold RESET in the LOG clear menu to clear chart data and log data. Hold RESET in ODOM mode to zero the odometer. (+) BUTTON Increments values while setting. (-) BUTTON Decrements values while setting. FOOT POD 4 VIEW FROM ABOVE TOE SIDE VIEW Loosen your shoelaces. Place the rungee cord beneath 2 or 3 lace crossings. Snap the rungee cord into the slot at the front of the pod. Tighten your laces and tie your shoes comfortably. The foot pod should be firmly attached with the narrow end of the pod facing your toe. If the pod is loose, place the cord beneath another lace crossing. The pod may remain attached to your shoe between activities. Also, the cord may be laced into the shoe and remain there for convenience and added security. FOOT POD BUTTONS The foot pod has three states (ON, OFF and COMM LEARN) that are controlled by pressing the rubber button. Unique sounds confirm the state you have entered. PRESSES WHAT THEY DO ONE Turns pod ON. When the pod is off, push and hold the button until you hear a beep. On button release, you will hear a single confirmation beep. The pod is now ready for your activity. When the foot pod is communicating with the watch, the foot icon on the watch display will be lit. TWO Turns pod OFF. Pressing the button twice in quick succession turns the pod off. A descending tone confirms that the foot pod is off. THREE Allows a watch to learn a foot pod ID. Pressing the button three times in quick succession resets the COMM Address. Three beeps confirms that the foot pod is in COMM LEARN mode. Now any FS-1 watch can lear…

Circuit Description of Link unitFCC ID O9DLA (referring to Block Diagram) The Link is designed to be attached to the RS-232 serial port of a personal computer (“PC”), and its purpose is to receive and transmit data via a 915 MHz radio link to a control and display unit worn on a person’s wrist (“Wrist unit”). It is part of the FitSense Technology model FS-1 system. The entire Link circuit is built on a single printed circuit board and is connected to a PC serial port through an attached cable terminated with a DB-9 female connector. The unit is powered from the RS-232 RTS and DTR lines from the PC, through the linear Voltage Regulator. A battery of two AA cells and a switched-capacitor type DC-DC converter IC will turn on and power the Link if the Voltage Regulator output is insufficient. An RS- 232 Transceiver IC converts the serial signal levels between the RS-232 standard and the Link’s 3.3 volt signal levels. The UART circuit is a microprocessor programmed to operate as a UART and buffer for the RS-232 serial data to and from the PC. It communicates directly with the main Microprocessor. The Microprocessor interprets and formats the serial data stream from both the PC and the 915 MHz Transceiver. The bit stream is formatted to conform to the FS-1 network protocol and applied to the transmitter input of the 915 MHz Transceiver. The Microprocessor also receives data from the 915 MHz Transceiver through a receive bit stream. In addition, the Microprocessor monitors the battery and operates a blue LED status indicator. The 915 MHz Transceiver is a RF Monolithics TR1000, with its necessary passive parts. It is a SAW-based device using an ASH (Amplifier Sequenced Hybrid) receiver with no local oscillator. The Transceiver operates in A1 mode (OOK), with a transmission data rate of approximately 9600 Bauds. The antenna is printed on the Link’s circuit board that contains the Transceiver and other circuits. There are no adjustable parts in the Link, and no tune-up procedure.

Radiated testing was performed at an antenna to EUT distance of 3 meters below 1 GHz, and at a distance of 3 or 1 meter(s) above 1 GHz. The actual test distance used is noted in the test data sheets. The device’s performance was investigated to 10GHz. The EUT was powered by two Duracell Ultra AA batteries for all tests. Fresh batteries were used for all testing. Since the NetLink can be operated in any orientation, the emissions were maximized in each of the three orthogonal axes and the maximum reading was recorded. The integrated antenna cannot be maximized separately. All other performance tests were made in accordance with the procedures outlined in Part 15 of CFR 47. The applicable sections provided under Part 15 are provided in the measurement section of this report. Discussion of CFR47 Part 15.249 Testing Procedure The FS-1 NetLink is part of a system involving four separate units. The NetLink receives data from the FS-1 Watch (a separate part of the FS-1 system) and downloads the data to a PC. During the download cycle, the NetLink performs a handshaking operation with the Watch, thereby utilizing a transmitter. The duration of the download cycle varies between approximately 20 to 30 seconds, thereafter the download must be reactivated. The download cycle was continuously reactivated and peak readings were taken during that time.
