While we provide some guidance here, you should always consult your physician before beginning or modifying an exercise program. 3 to warm up and prepare to work in your target exercise zones. For example, you can “warm up” in the Light Exercise zone, spend the majority of your exercise in the Weight Management zone, and then even spend a bit of time in the Aerobic Base Building Zone. The intensity of Zones 4 and 5 is demanding enough that exercise in these zones should be done for limited intervals of a workout and with the guidance of a qualified medical or coaching professional.

To program your Timex Digital Heart Rate Monitor to put you in your Ideal Weight Management Zone, use the Target Heart Rate Zone Chart. Timex and the Ironman® Institute® Take the Guesswork Out of Fitness Improved fitness and athletic performance are as simple as setting a realistic fitness objective and using the Timex Digital Heart Rate Monitor as a personal trainer. Here is how it works. First, Select a Fitness Objective That’s Right for You • Improve Your Fitness • Lose Weight and Burn Fat • Increase Stamina and Aerobic Base • Improve Your Fitness Condition • Achieve Peak Athletic Performance Second, Select a Heart Rate Exercise Zone That’s Right for You Heart Rate Zone Exercise is the methodology widely used by fitness and sports training professionals for achieving the above fitness objectives. The new Timex Digital Heart Rate Monitor will automatically show you when you are in the Exercise Zone you choose, and signal when you are not. It functions as a personal trainer to help keep your body exercising at an intensity level that can help you achieve your desired Fitness Objective without over- or under-exercising. The Ironman Institute Offers the Following Guidelines for Selecting Your Heart Rate Exercise Zone There are five basic heart rate exercise zones. Simply select a zone that is the fitness goal you want to achieve during a particular exercise. When you begin your exercise, always start out at a lower zone and allow your body 2 5 Why Heart Zone Exercise is Widely Used by Fitness/Sports Training Experts. Regular exercise can help keep the heart, lungs and muscles “in shape.” The heart supplies the lungs and muscles with the oxygenated blood sup- ply needed to exercise. Heart Rate represents the effects of exercise on all parts of the body. Heart Zone Exercise systematically conditions the heart, lungs, and muscles to perform at higher levels so the body can stay in shape. Optimal Conditioning is Simply a Higher Training Habit You do not have to be an athlete to get into optimal shape. Anyone at any age can do this by using exercise to reach your optimal condition. Follow these guidelines: • Pick the exercise activities you enjoy or the ones you need for a training program. • Train at the appropriate Target Heart Rate for 30 to 60 minutes 3-4 times a week. • You will approach optimal condition when you can sustain a com- plete exercise session without “burnout” or excessive fatigue or excessive soreness. Your Timex Digital Heart Rate Monitor is Your Electronic Fitness Coach. You can walk, run, bike, use exercises machines, or do any aerobic exercise with the Timex Digital Heart Rate Monitor. The key to achieving and maintaining your desired Fitness Objective is to exercise in your Ideal Heart Rate Zone . Select which level of condition represents your current physical condition and locate the Lower and Upper Heart Rate Zones for your age from the Target Heart Rate Zone chart. See Operating the Digital Sportswatch to program your Lower and Upper Heart Rate Zone into your Timex Digital Heart Rate Monitor. The latest findings on fitness show anyone at any age can get fit/stay fit without being fanatic. For the “moderate” exerciser, staying fit can be as simple as: • Exercise 3 Times a Week • Exercise 30-45 Minutes Each Time • Exercise in Your Appropriate Target Heart Rate Zone You are ready for higher levels of physical activity when you can work out for this amount of time and heart rate without breathing hard and with minimal soreness. 4 7 How To Set Time of Day & Calendar A.

Technical Description of the Timex Corporation Wireless Heart Rate Monitor Transmitter and Watch Receiver Principle of Operation The heart rate monitor is composed of two units; a transmitter (M515) chest strap and a receiver (M818, M838, M846, M516) watch. The transmitter measures the weak electrical signal generated on the surface of the user’s skin by the beating of the heart, transforms this information into a digital format, and transmits the data to the receiver watch. A special auto power-on circuit ensures that the transmitter is only active while it is placed on a chest, so as to conserve battery power. The receiver watch receives the transmitted radio signal, decodes it, and displays the measured heart rate value on the LCD screen of the watch. The watch also functions as a full feature digital time piece. The system uses an FSK (Frequency Shift Keying) based simplex data communication scheme. The data communications rate is 1024 baud. The transmitter is operating with a carrier frequency of 139.25 KHz with a mark frequency of 137.5 KHz and a space frequency of 141.0 KHz, and the transmitting antenna is a loop type with a ferrite core. Distance and Angles The system is specified to work up to a maximum distance of 120 cm between chest strap and the watch receiver in air. The range, however, is dependant on the relative orientation between the receiver and the transmitter. Overview The M515 transmitter uses a standard EOC6008 Epson 4-bit microcontroller to measure the heartbeat, encode this information, and transmit it to the receiver. An ECG sensor circuit senses each heartbeat by measuring the voltage potential across the user’s chest. A so called auto power-on circuit allows the M515 device to conserve power by ensuring that it is only powered up when the device is placed on a chest. Three back-end circuits allow the microcontroller to transmit information to the receiver - a modulator circuit modulates the information to generate the required FSK signal; a pulse shaper circuit prepares the signal for transmission; and an antenna driver circuit handles the actual transmission. The heart rate chest strap transmitter obtains power from an internal 3.0 Vdc coin cell battery, and the receiver watch obtains power from its own internal 3.0 Vdc coin cell battery. Overall Operation of the Transmitter At the beginning of the exercise session the strap is placed on the chest. The auto power-on circuit senses this and sends a signal to the microcontroller (SENSOR_EN goes high). This signal also enables the ECG Sensor circuitry which allows heart beat pulses to be read into the microcontroller. For as long as SENSOR_EN is high, the ECG Sensor circuit will continue to send a signal to the microcontroller whenever it senses a heartbeat from the user’s chest. Each heartbeat is signaled with a positive pulse – PULSE_IN is pulsed high. For the duration of the exercise session, the microcontroller will transmit a digital data packet over the air to the watch receiver every 2 seconds. This data packet contains ID information as well as the user’s heartbeat rate. A packet transmission takes places as follows: the transmitter is first powered up by the microcontroller pulling RF_EN high, then the data line is activated by pulling DATA_OUT high, after which actual transmission commences by pulling FSK_EN high. The microcontroller may now transmit the data packet by toggling DATA_OUT high and low. After each transmission , FSK_EN is pulled low followed by DATA_OUT and lastly RF_EN. At the end of the exercise session the strap is removed and SENSOR_EN again goes low. The ECG Sensor circuitry is immediately powered down, and after the microcontroller senses the change on the SENSOR_EN line all transmitting is terminated.
