Personal Safety

• Assemble and operate the treadmill on a solid, level surface. Locate the treadmill at least 4 feet from walls or furniture. Keep the area behind the treadmill clear.

• Check the M9.21i or M9.21si treadmill before each use. Completely assemble the treadmill before using it.

• Turn OFF (O) and unplug the treadmill when adjusting or working near the rear roller. Do not adjust the running belt when someone is standing on the unit.

• Keep all electrical components, such as the motor, power cord, and ON/OFF (I/O) switch, away from water or other liquids to prevent shock. Do not set anything on the handrail, electronic console, or hood. Never place liquids on any part of the unit.

• Always attach the safety clip to your clothing at waist level prior to beginning your workout. The safety clip is connected by a cord to the magnetic safety key in the electronic console. If you encounter difficulties, you can stop the running belt by pulling on the cord to disengage the magnetic safety key from inside the console. To resume operation, the magnetic safety key must be replaced.

• When the treadmill is not being used, remove the magnetic safety key and store it in a safe place to prevent unauthorized use.

• Wear proper exercise clothing and shoes for your workout—no loose clothing. Do not wear shoes with heels or leather soles. Check the soles of your shoes and remove any dirt and embedded stones. Tie long hair back.

• Keep all loose clothing and towels away from the running surface. The running belt will not stop immediately if an object becomes caught in the belt or rollers.

• Use care when getting on or off the treadmill. Use the handrails whenever possible. Step onto the running belt when the speed is at or below 1 mile per hour (1.6 kilometers per hour). Never step off the treadmill while the running belt is moving.

• Before the running belt begins moving (prior to your workout), and after it stops (at the end of your workout), straddle the belt by placing your feet firmly on the right and left side platforms.

• Never turn ON the treadmill when someone is standing on the machine.

• Keep your body and head facing forward. Never attempt to turn around on the treadmill when the running belt is moving.

• Do not rock the unit. Do not stand on the handrails, electronic console, or hood.

• Do not attempt to service the treadmill yourself other than the assembly and maintenance instructions found in this manual.

• Do not overexert yourself or work to exhaustion.

• Stop your workout immediately if you feel any pain or abnormal symptoms, and consult your physician

Precor Heart Rate Option—Safety Guidelines

The Precor Heart Rate Option was created and designed exclusively for Precor products. The equipment is extremely sensitive—you should use the heart rate option with this in mind and take time to read the following guidelines:

• Handle the Precor Heart Rate Option with care. Do not drop the equipment. It might damage the transmitter and you could void the manufacturer’s limited warranty.

• Do not use the chest strap near strong electromagnetic radiation sources. Television sets, electric motors, radios, and high voltage power lines can interfere with the heart rate signal that is being transmitted to the receiver and might affect the heart rate readings that appear on the electronic console.

page 3

• Use only one chest strap at a time inside the range of the receiver. If the receiver tries to process several signals simultaneously, an incorrect heart rate reading could result. Be sure to keep any other transmitters at least 5 feet (1.5 meters) away from the receiver on your M9.21i or M9.21si treadmill.

• Keep the equipment dry. Although the chest strap should not be immersed in water, wetting the electrodes and your chest will improve the initial performance. Note that perspiration on the chest strap during workouts is normal and actually enhances the signal being sent from the chest strap’s transmitter.

• To conduct the electrical impulses from your heart, the chest strap’s electrodes require a certain percentage of salts and minerals in the water used to wet them. The electrodes continue to transmit your heart rate reading as long as they are in contact with your skin and your skin is providing enough moisture through your perspiration to keep the electrodes wet. However, if the concentration of salts in your perspiration is not high enough to conduct electrical impulses and send them to the receiver, your heart rate reading will appear erratic or not appear at all. Some people cannot use the heart rate feature because they do not have the proper body chemistry.

• Do not use the chest strap if you are taking any medication or have a cardiac pacemaker. Inaccurate heart rate readings can occur due to medication or electrical impulses from the cardiac pacemaker.

• Stretching or bending the electrode strips on the chest strap may cause the strips to lose their conductivity. Handle the chest strap with care.

• After extensive use, the chest strap (transmitter) may wear out, causing inaccurate heart rate readings. With every use, check the strap for excessive wear and replace it if necessary. See

in the maintenance section of this manual.

Precor treadmills are designed for the enjoyment of the serious runner as well as the dedicated walker. By following the above precautions and using good common sense, you will have many safe and pleasurable hours of healthful exercise with your Precor treadmill.

Information Regarding Use in the U.S.A. and Canada

Federal Communications Commission, Part 15 The M9.21i or M9.21si treadmill 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 protection against harmful interference in a residential installation. The M9.21i or M9.21si treadmill generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the owner’s manual instructions, may cause harmful interference to radio communications.

Before You Begin

This manual explains how to assemble, use, and maintain the M9.21i or M9.21si Low Impact Treadmill. The following conventions are used in this manual:

“Note:” Contains additional information that applies to the preceding text.

“Important:” Indicates information to which you should pay special attention.

“CAUTION:” Indicates steps or information necessary to prevent harm to yourself or damage to the equipment.

“WARNING:” Provides instructions to prevent electrical damage to the equipment and prevent injuries to yourself or others.

“DANGER:” Indicates steps you must take to

Thank you for purchasing the Precor M9.21i or M9.21si Low Impact Treadmill which feature several sophisticated and beneficial technologies:

Technology, Smart Rate®

Ground Effects allows the treadmill’s running bed to “float” on specially formulated elastomeric springs which cushion impact and control lateral motion without diminishing the bed’s lively, responsive feel. Because it’s fully suspended, the bed provides optimum shock absorption anywhere your feet land, not just in the center of the running area.

Integrated Footplant Technology (IFT) is a microprocessor-regulated motor control system. This patented technology collects motor and belt speed data, using it to monitor your workout and enhance your safety and comfort. It replicates the natural walking and running motion of your feet. By allowing slight, natural speed variations throughout your stride, Precor treadmills reduce shock and pounding to your body.

The console’s display offers varying selections that provide motivating feedback about your workout. The display also incorporates the latest in cardiac monitoring to provide Smart Rate® — a visual aid that lets you, the user, see your heart rate with a glance. On the M9.21i or M9.21si, the optional Precor receiver must be installed and the Precor Heart Rate Option chest strap worn, before the graph on the display can light up with colored cells to indicate your exercise intensity.

The M9.21i Low Impact Treadmill offers an easy-to-understand electronic console that gives motivating feedback about your workout. Professionally designed exercise options incorporate the latest in exercise science. Three different modes enhance your workout capabilities: Manual, Interval, Weight Loss, Random, and Heart Rate Control course which requires the Precor Heart Rate Option kit. The Heart Rate Course monitors your heart rate within a target zone (usually 85% of your maximum heart rate) and automatically changes the incline to keep your heart rate in that zone when you wear the chest strap during your workout.

page 20

(Cool down)

Note: Always allow yourself a cool-down period of a few minutes before bringing the running belt to a complete stop. Cooling down after your workout helps reduce muscle stiffness and soreness by transporting excess lactic acid out of the working muscles. It also helps your heart rate return to its normal (non-exercising) state. You can access the manual mode (MAN’L) from any program by tapping STOP twice in quick succession. Manual mode enables you to change the speed and incline and adapt a cool-down period into your workout.

11. If desired, after reviewing the displays, reset them to zero by pressing HOLD TO RESET for several seconds.

12. Detach the safety clip from your clothing and remove the magnetic safety key from the electronic console. Turn OFF the treadmill.

13. To prevent unauthorized use, store the safety key in a safe place.

Using the QUICK START™ Feature

CAUTION: Hold onto the handrails when you

press QUICK START. The running belt starts automatically at 1 mph after the display scrolls the message “Belt Starting 3, 2, 1,..”

The words “quick start” imply that you can start your workout immediately. Once you insert the magnetic safety key and attach the safety clip to your clothing, the QUICK START feature on the M9.21i or M9.21si treadmill allows you to bypass the setup prompts and access manual mode. The weight setting defaults to 150 pounds (68 kg) so all calorie calculations and their associated displays are based on a body weight of 150 pounds (68 kg). The Smart Rate display will not work when you use the QUICK START key.

Note: Any prompts that appear after the “SELECT COURSE” prompt require your input before you can proceed. You can press QUICK START at any prompt and access manual mode features. However, QUICK START is disabled once you enter a program and begin your workout.

Retrieving the Previous Workout Program

To retrieve the previous workout program, simply tap the ENTER key successively three times while the prompt “ENTER WEIGHT” is being displayed. Note that if someone else has exercised on the treadmill after your workout, whatever program he or she used will be the one that is restored from memory.

Pausing Your Workout

You can pause at any time during your workout. Use this feature to rest or take a short break. To pause while working out, press the STOP key. The running belt stops. Remove the safety key clip and straddle the running belt so that you can safely step off the treadmill. Your workout statistics freeze and remain displayed on the console until you resume your workout.

Do not rely on the Pause feature as a way to end your workout. If you wish to end your workout, follow the instructions in

Ending Your Workout

To resume your workout, straddle the running belt, attach the safety key clip to your clothing, press the SPEED ▲ key to start the running belt, hold the handrail, and step onto the running belt while the speed is at or below 1 mph. Your workout statistics continue from where you left off. Continue to press the SPEED ▲ key, to increase the speed to a comfortable level. Once you are comfortable with the walking or running speed, you can remove your hands from the handrail.

Cooling Down After a Workout

Cooling down after your workout is important because it helps reduce muscle stiffness and soreness by transporting excess lactic acid out of the working muscles. Cooling down for at least 3 minutes helps provide a smooth transition that allows your heart rate to return to its normal (non-exercising) state.

You can cool down after a workout by accessing Manual mode (MAN’L). Tapping STOP twice in quick succession accesses MAN’L mode from the preprogrammed courses (M9.21si only).

Ending Your Workout

To end your workout, take the following steps:

1. Hold onto the handrail and press the STOP key or press the SPEED ▼ key until the running belt slows to a gradual stop. The displays on the console freeze which lets you review your workout statistics.

2. Continue to press STOP (HOLD TO RESET) for a few more seconds to add your workout statistics to the cumulative totals and return to the Precor banner.

3. Straddle the running belt and step off the treadmill.

4. To prevent unauthorized use, remove the magnetic safety key from inside the electronic console and store it in a safe place. Turn OFF the treadmill.

Changing the Interval Course Profile

Interval training provides numerous benefits. Since interval training segments the workout into smaller components, a 20- or 30-minute workout seems to pass more quickly. In addition, studies have shown that it is a more efficient method for achieving aerobic benefits—you start seeing improved cardiovascular fitness much sooner with less effort. Studies also show that people who interval train are more likely to stick with their fitness program.

The interval course on the M9.21i or M9.21si treadmill lets you set the course intervals according to your training regimen. It alternates between 60 seconds of “Rest” and 60 seconds of “Work.” During the Rest interval, you can walk or jog slowly; during the Work interval, you can stride quickly or run. You set the speed and incline for the first rest and work interval and the software takes over from there, repeating the intervals throughout the course until you press the STOP key.

At any point during the workout, you can change the speed and incline of the current interval. For example, if 8 mph is a little faster than you prefer during a Work interval, simply use the SPEED ▼ key to reduce speed. The software remembers the new speed for the next Work interval.

If you have purchased the Precor Heart Rate Option and installed the heart rate receiver, you can monitor your workout using the Smart Rate and HEART RATE displays.

Note: If you pause your workout during an Interval mode, you must reset the speed of the mode you were in when you paused your workout. For example, if you paused your workout during the Rest interval, you must reset the speed for that interval. In this example, you would not need to reset the speed for the Work interval since it is stilled stored in memory.

Below are some suggestions that may help you incorporate the Interval mode into your workout:

• If you are starting an exercise program, the Interval mode option can help you increase your workload gradually. For example, in the beginning, you may simply want to specify the same speed and incline for both Work and Rest intervals. Then, to increase your effort level, change to a higher speed and/or incline for your Work interval.

• If you are training with the goal of maintaining a constant pace when on level ground or grade, specify the same speed for both Work and Rest intervals. Then, gradually increase the incline during the Work interval until you can maintain a constant pace.

To use the interval course, follow the steps in At the “SELECT COURSE” prompt, use the ▼▲ keys to display “INTV,” and press ENTER.

To set the interval for the course, take the following steps:

1. When you see “ENTER REST SPEED & INCLINE” scroll across the display, stand on the running belt with one hand on the handrail, prepared to start walking. With your other hand, press the SPEED ▲ key until you reach a comfortable rest speed, either running or walking. Press the INCLINE▼ or ▲ key to specify an appropriate incline. When the desired speed and incline are displayed, simply continue working out—you do not need to press ENTER.

Once you reach your desired rest speed and incline, the treadmill returns to it at the beginning of each rest interval, until you change the speed or incline, or end your workout.

2. When “ENTER WORK SPEED & INCLINE” scrolls across the display, specify your work speed (up to 10 mph). With one hand on the handrail, use the other hand to press the SPEED ▼ or ▲ keys until the desired work speed is shown. Use the INCLINE▼ or ▲ key to set the incline. When you are comfortable with the rest and work speeds and inclines, you can let go of the handrail.

Each rest and work interval lasts 60 seconds. The display automatically counts down to the next interval. When the count reaches 30 seconds, the display changes and gives information about distance travelled, time elapsed, speed, calories burned, and percent of incline.

When the treadmill changes intervals, it informs you by scrolling “GOING TO REST SPEED” or “GOING TO WORK SPEED” across the display.

Working Out on Your M9.21i or M9.21si Treadmill

page 22

Using the interval course mode, you can cool down before ending your workout by pressing STOP twice in quick succession. The treadmill enters Manual Mode, letting you specify the speed of your cool-down period.

Using the Weight Loss Program

The Precor Weight Loss Program incorporates the latest findings on fat-burning and weight loss through exercise. It is based on research at the world-renowned Cooper Institute for Aerobics Research.

CAUTION: Before beginning any fitness program, you should obtain a complete physical examination from your personal physician.

CAUTION: The treadmill may automatically change incline when you enter a program. Stay clear of the lift mechanism and hood area until the treadmill has completed the recalibration process.

Table 1

Speed calculated in mph & kph

The Weight Loss Program is similar to the interval course program on your M9.21i or M9.21si treadmill. The Weight Loss Program provides a 28-minute workout with inclines preset to a minimum level for the 4-minute rest interval and a maximum level for the 4-minute work interval.

You can adjust the incline during any interval segment. However,

The speed remains constant and the preset 4-minute rest and work intervals continue to repeat until you press the STOP key. If you want to adjust the speed, press the SPEED▼ or ▲ key until the desired speed appears in the display.

Always monitor your pulse during and at the end of your workout. If you purchased the Precor Heart Rate Option and have installed the receiver and are wearing chest strap, you can monitor your heart rate through the Smart Rate and HEART RATE displays. For the ideal “weight loss” range, your heart rate should be between 55% and 70% of your maximum aerobic heart rate. It should never exceed 80% of your maximum aerobic heart rate or go above your training zone. Refer to Diagram 15 in

Getting the Most Out of Your Workout

for your appropriate training zone.

Important: If you use the Precor Heart Rate Option, you can adjust the rest or work intervals if your heart rate is above or below the recommended zones for your age. For the Weight Loss course, try to maintain your heart rate at the lower end (55% of maximum heart rate) while in the “rest” intervals and keep it at 70% of maximum heart rate while in the “work” intervals.

Using the Manual Course Program

CAUTION: Hold onto the handrails when you

press QUICK START. The running belt starts automatically at 1 mph after the display scrolls the message “Belt Starting 3, 2, 1,..”.

Manual mode lets you use the M9.21i or M9.21si treadmill for an indefinite period of time while controlling the speed and incline.

You can choose the Manual course program in two different ways:

• pressing QUICK START at the Precor banner or any set-up prompt displays the manual course profile. The weight setting defaults to 150 pounds (68 kg) so all calorie calculations and their associated displays are based on a body weight of 150 pounds (68 kg). The Smart Rate displays do not work when you use QUICK START. For more information, refer to

QUICK START Feature

• entering your weight and selecting the “MAN’L” course. At your next workout (if no one else has used the treadmill), rapidly tap ENTER three times to access this same program.

When you choose the Manual program, the program’s course profile appears in the display and shows a flat constant course. The INCLINE▼ or ▲ keys change the incline and the SPEED▼ or ▲ keys affect the speed of the running belt.

Important: To end a workout in Manual mode, you need to press STOP or press the SPEED ▼ key until the running belt stops. Press HOLD TO RESET for a few seconds to clear the display.

Using the

Using the Random Course

Choosing a random course provides variable course profiles. Each course profile is “randomly” selected by the M9.21i or M9.21si software. Every time the Random course is selected, a different course profile appears.

CAUTION: If this is the first time you have operated this treadmill, DO NOT STAND on the running belt until you become familiar with treadmill’s operation. Be sure to read and follow the general guidelines found in “Working Out on Your M9.21 or M9.21s Treadmill” prior to using the treadmill.

CAUTION: The treadmill may automatically change incline when you enter a program. Stay clear of the lift mechanism and hood area until the treadmill has completed its recalibration.

Using a Preprogrammed Course on the M9.21si

To use a preprogrammed course, follow the instructions below. Remember, when you use the electronic console, hold onto the handrail to maintain your balance. You should also use the handrail whenever you speed up, slow down, or stop the treadmill.

The M9.21si is equipped with six preprogrammed courses and two custom courses that vary in distance, time, and incline. Refer to the label on the electronic console for a representation of the course profiles.

To use the preprogrammed courses, follow the steps in

Low Impact Treadmill

1. At the “SELECT COURSE” prompt, enter a program name “WALK” or “RUN.” The WALK courses combine .05-mile segments with a set series of inclines. The RUN courses

combines .1 mile segments. The percent of incline and the frequency with which inclines are encountered indicate the difficulty of the course. For example, WALK EASY takes the user through inclines ranging from 0 to 3 percent grade, while RUN ADV uses inclines in the minimum to maximum range on a more frequent basis. The software simply repeats the segments until the distance or time limit you set is reached, or you press the STOP key.

Note: If you do not press ENTER to select a course, after 10 seconds the prompt “PRESS ENTER TO BEGIN” appears. This prompt continues to scroll across the display every few

seconds until ENTER is pressed.

2. At the “SELECT MILES (kilometers)” prompt specify the length of your course. Press the ▼ or ▲ keys to choose distance. Press ENTER when the desired distance appears.

Note: You can change the “SELECT MILES” prompt to “SELECT TIME” if you prefer to measure your workout by distance. Follow the procedure in

Creating Custom Courses on the M9.21si

You can program the M9.21si and create your own course profiles using the two custom courses (“CUST1” and “CUST2”). Programming a custom course is easy. You just create the custom courses as you work out by determining the speed and incline for each 0.1 mile segment along the 8-mile maximum course length. Speed and incline settings are saved once every .1 of a mile which equals 10 dots on the display. Once you complete your workout, the course is stored in memory and can be automatically recalled using the same program number.

CAUTION: After pressing ENTER, clear an existing custom course profile by simulta-

▼▲

neously pressing both the INCLINE

keys for at least 3 seconds. The course profile reverts to a blinking line at 0% incline. Be cautious about performing this procedure. Once you clear an existing course profile, you cannot retrieve it.

To create a custom course, follow the steps in

Impact Treadmill

1. At the “SELECT COURSE” prompt, choose your custom course: either “CUST 1” or “CUST 2.” Press the ▼ or ▲ keys until you see the desired course, then press ENTER.

Note: After pressing ENTER, a prompt scrolls across the display warning you that the custom course contains set speed and inclines. You are not to use the course if you are not familiar with it.

Using the Precor Heart Rate Option

The Precor Heart Rate Interactive System has many unique features. When you use the Precor Heart Rate Option and have the optional heart rate receiver installed in the electronic console, your heart rate can appear on the display. The Smart Rate and Heart Rate displays simplify the correlation between heart rate and exercise. You don’t have to stop concentrating on your workout to find your pulse anymore. It is displayed right in front of you. When you use the Heart Rate Course, the software monitors and maintains your heart rate in the target zone best suited for your specific needs.

When you maintain your heart rate between 70% and 85% of your maximum aerobic heart rate, you are improving your overall cardiovascular/cardiorespiratory fitness level. If you maintain your heart rate between 55% and 70% of your maximum aerobic heart rate, you are burning enough calories that, when continued on a regular basis for 30 minutes or more, provides the greatest fat-burning (weight loss) benefits. Before you use the chest strap transmitter, Heart Rate Course, or Weight Loss program, please study this section thoroughly. Included in this section are the following:

• wearing the chest strap transmitter • using the Heart Rate Course

• utilizing the heart rate interactive system • correcting inconsistent heart rate readings Important: If you do not use the Precor Heart Rate Option and the optional heart rate receiver

according to the guidelines found in this manual, you could jeopardize the accuracy of your heart rate readings or void the Precor limited warranty.

Wearing the Chest Strap Transmitter

The Precor Heart Rate Option is a completely wireless system. A built-in receiver displays continual feedback about your heart rate when you wear the transmitter strap around your chest. No bulky wires or cables interfere with your movements.

The wireless chest strap contains the electrodes that transmit your heart rate (pulse) to the receiver. To get an accurate reading, the electrodes need to be your skin.

Take the following steps to put on the chest strap:

With the proper adjustment of the chest strap, you are ready to begin using the Precor Heart Rate Option.

Be sure to wear the chest strap underneath your clothing

1. Determine the length of the strap by wrapping it around your chest. Without stretching the strap, check the distance between the two ends of the strap. For a snug fit, the ends of the strap should be about 6 inches (15 cm)

apart. See Diagram 11. Adjust the tightness of the chest strap by sliding the buckle along the strap.

2. Remove the strap from around your chest and dampen the electrode strips with tap water as shown in Diagram 12 or use the Precor spray. Do not use deionized water. To function properly, the electrodes need the salts and minerals found in non-purified water. Once you begin your workout, your perspiration keeps the electrodes moist.

3. Buckle the strap around your chest. The strap should feel snug, not restrictive. Make sure that the transmitter lies horizontally across your chest and is centered in the middle of your chest. See Diagram 13.

Note: The chest strap transmitter has a one-year warranty. Some units contain a replaceable battery. To change the battery, refer to page 32.

Utilizing the Heart Rate Interactive Capabilities

You can make each program on the treadmill a heart rate interactive course by monitoring and maintaining your heart rate in the Smart Rate® zone best suited for your specific needs. You can access Smart Rate only if the optional heart rate receiver is installed in your unit and you wear the Precor chest strap. The Smart Rate indicator lights do not appear when you use QUICK START™.

CAUTION: Keep in mind that the “Heart Rate” or “Training” zones are approximations. Always check with your physician to learn what the appropriate heart rate is for your level of fitness. Do not push yourself beyond the recommended range.

CAUTION: Refer to Precor Heart Rate Option— Safety Guidelines for other important safety tips.

Before using the Heart Rate capabilities on the M9.21i or M9.21si, take time to read the following guidelines.

• Consult with your physician before engaging in any vigorous exercise. Do not use the Heart Rate Course until authorized by your physician.

• Slow down and stop immediately if you experience any pain or abnormal symptoms.

• Gently stretch you lower body and back before and after working out to help prevent stiffness or soreness.

• Know your heart rate (pulse) and your physician-recommended heart rate training zone. Individual heart rates vary according to several physiological factors and may not correspond directly with the tables provided.

• You should not use the Heart Rate capabilities if you are taking any medications that either speed up or slow down your heart rate.

• Always face forward on your treadmill and only use the handrails for balance.

handrails to support your weight

• Keep in mind that you are working with very sensitive equipment and upper body movement should be kept to a minimum.

• After putting on the chest strap, turn the treadmill ON “O” and position yourself on the running belt for a minimum of 15 seconds. This allows the treadmill to acknowledge the presence of the transmitter.

• While using the chest strap, face the electronic console and stay within 3 feet of it. If you move outside the 3-foot range, the receiver may have difficulty picking up your heart rate signal.

Do not use the

CAUTION: Always check with your physician to learn what the appropriate heart rate is for your level of fitness. Do not push yourself beyond the recommended range.

• Remember to incorporate a cool-down period into your workout to help lower your heart rate and minimize muscle stiffness or soreness.

Using the Heart Rate Course

The Heart Rate Course has been designed from research conducted at the world-renowned Cooper Institute for Aerobics Research. The HRC program must be used in conjunction with the Precor Heart Rate Option. You can use the Heart Rate Course to maximize your aerobic workout. Once you start the program, the software automatically adjusts the incline (or prompts you to adjust the speed, if necessary) to keep your heart rate within the cardiovascular heart rate zone.

Note: You must wear the Precor chest strap to use the Heart Rate Course. To use the course follow the steps in

and choose “HRC” at the “SELECT COURSE” prompt. The following occurs:

1. A prompt asks you to select a workout time. The software defaults to 20 minutes if no previous record exists. You can select a range of time between 5 and 99 minutes in 1-minute increments. Use the▼ or ▲ keys to specify your workout time. Press ENTER.

2. A scrolling prompt appears to query you about your recommended heart rate zones. The upper limit of your target heart rate appears and scrolls across the display. Use the▼ or ▲ keys if you wish to override the recommended heart rate. Press ENTER. A chart showing the recommended heart rate zones can be found in Diagram 15 in

3. Another scrolling prompt appears to ask you to verify your lower heart rate limit. Use the▼ or ▲ keys if you wish to override the recommended heart rate. Press ENTER.

4. The software verifies that it detects the heart rate signal and a prompt appears requesting that you press the SPEED ▲ key to begin your workout.

Important: Hold onto the handrail. If the treadmill is not already at 0% incline, it automatically returns to 0% incline.

5. Use the SPEED▼ or ▲ keys to control the running belt’s speed. The treadmill automatically adjusts the incline to keep your heart rate within the target zone. You can use the INCLINE or SPEED ▼ or ▲ keys any time during the 3-minute warm-up period to get your heart rate into its target zone. The program automatically takes over once your heart rate is in the target zone or the 3 minutes elapse. If, during your workout, your heart rate falls outside of the target range, the treadmill automatically overrides the incline (in 2% increments up to 10%) to bring your heart rate to within the target zone.

Note: If your heart rate cannot be detected or no heart rate is transmitted for more than 3 minutes, the Heart Rate course begins, but its operation is the same as Manual mode. Every 30 seconds the program checks for a heart rate.

6. When you reach the time limit, the treadmill automatically enters Manual mode so you can begin a cool-down period. You can change the speed and incline by pressing the ▼ or ▲ keys.

During your cool down, the displays on the console continue to appear. The TIME display counts up from zero, so you know how long you have been in the cool-down period. It is recommended that you cool down for at least 3 minutes. This helps your heart rate to return to a normal rhythm.

7. Hold onto the handrail and press the STOP key or press the SPEED ▼ key until the running belt slows to a gradual stop. The displays on the console freeze which lets you review your workout statistics. Straddle the running belt and remove the safety clip from your clothing. Step off the treadmill if you have finished your workout and turn it OFF.

8. To prevent unauthorized use, remove the magnetic safety key from inside the electronic console and store it in a safe place.

Correcting Inconsistent Heart Rate Readings

If you have purchased the Precor Heart Rate Option and the treadmill cannot pick up your heart rate signal or messages appear on the display regarding heart rate errors, stop your workout and take the following steps:

Important: Be sure that the optional heart rate receiver is installed in the electronic console. Also, review the information found in the Safety Information,

A workout on the M9.21i or M9.21si Low Impact Treadmill provides excellent and efficient cardiovascular conditioning, while strengthening and toning all the major muscle groups in the lower body. Darkened areas in Diagram 14 indicate the muscles improved.

To get the most out of each workout, a general understanding of the principles behind aerobic training is invaluable. The best source of information is your specialty fitness dealer. In addition to providing information on which exercise equipment is best for your individual needs, your fitness dealer can provide useful advice on training, technique, and exercise physiology. Your dealer can also recommend good books and audio/video tapes on these subjects.

How Hard Should I Exercise?

Studies show that to achieve the benefits of aerobic exercise, it is necessary to work out hard enough to raise your heart rate to a certain minimum level, called the “training zone.” Your training zone depends on your age and level of fitness.

Diagram 15 shows your recommended heart rate training zone, which is calculated using your age and your maximum aerobic heart rate. Your maximum aerobic heart rate is equal to 220 minus your age. The chart is based on a resting heart rate of about 72 for males and 80 for females. Your optimum training zone is between 65% and 80% of your maximum heart rate. For efficient aerobic exercise, work only hard enough to keep your heart rate in this zone. You will obtain the greatest fat-burning benefits when you exercise within the optimum training zone.

longer

, not harder.

Keep in mind that this zone is an approximation, to be used as a guideline—individual heart rates vary according to several physiological factors. To determine your training zone, find your age on the diagram, and then find the line where they intersect. For example, if you are 35 years old, your training zone is between 114 and 140 beats per minute. Remember this zone—this is the heart rate zone you should try to maintain as you work out.

If you do not have an accurate heart rate monitor, you can determine your heart rate by taking your pulse at a place that you can reach easily and comfortably while you exercise. Typical places for measuring heart rate are directly over the heart on the left side of the chest, on either side of the neck, over the temple, or on the thumb side of either wrist. Wherever you measure your pulse, make sure that you use your index and middle fingers—not your thumb. Your thumb has a strong pulse which can affect your pulse rate reading.

Once you locate your pulse, look at a clock with a second hand, and count the beats for six seconds. Multiply that number by 10 to determine the total number of beats per minute. For example, if you count 14 beats over six seconds, the total number of beats per minute is 140. Compare the total number of beats with your training zone as identified in Diagram 15. If necessary, increase or decrease your activity level to bring your heart rate into your training zone. You can regulate your work level (and heart rate) by changing belt speed and incline. Remember—your

heart rate is the definitive measure of how hard you are working.

Regardless of your fitness level, avoid doing too much too soon. Running or walking too fast or choosing too high of an incline are common errors. Give yourself time to become familiar with your treadmill and to improve your fitness level. Then you can gradually increase speed and incline to make your workouts more challenging.

page 30

How Long Should I Exercise?

The length of each exercise session depends on your fitness level. Exercise physiologists have determined that, to attain cardiovascular benefits from exercise, you should maintain your heart rate in its training zone for at least 15 minutes. This is in addition to your warm-up time, and does not include cool down. You should always allow several minutes to bring your heart rate into the training zone, by starting out slowly and gradually increasing work level. Similarly, use several minutes of light exercise after the workout to bring your heart rate down to near resting level.

The higher your fitness level, the longer you should maintain your heart rate in the training zone (between 20 and 30 minutes). Beginners should always start slowly, and gradually bring their sessions up to 20 minutes or more.

How Often Should I Exercise?

Research indicates that aerobic sessions of 20 minutes or more should be done at least three to five times a week to obtain significant cardiovascular benefits. Most experts agree that sensible eating habits and regular aerobic exercise are the keys to weight control and fitness. A recent study, which tracked several subjects over a period of years, conclusively shows that exercise, not dieting, is the key factor to long-term weight loss.

Maintaining the Low Impact Treadmills

CAUTION: Turn OFF the treadmill and disconnect the power cord before performing most maintenance tasks.

CAUTION: Do not use an abrasive cleaner on the strap. Do not immerse any part of the chest strap. Do not spray or pour liquids on any part of the equipment.

The M9.21i or M9.21si Low Impact Treadmill requires little maintenance to keep it running smoothly and efficiently. However, the customer is responsible for the typical maintenance tasks such as, cleaning the treadmill and adjusting the running belt. If you fail to maintain the treadmill as described below, it could affect or void the limited warranty.

Cleaning the Equipment

Your Precor treadmill relies on low friction for efficient operation. To keep the friction low, the treadmill must be as clean as possible.

Before a workout, use a damp, soft, clean cloth to clean the side platforms and running bed, (refer to Diagram 17 on page 33). This helps to remove any dirt or dust that might affect the smooth operation of the treadmill.

Vacuum the floor underneath the unit every week to prevent the accumulation of dust and dirt on the running belt.

To periodically clean the treadmill’s frame, electronic console, and running belt, use a solution of mild soap and water and dampen a clean cloth. To clean the running belt and the groves on the plastic trim strip, use a soft nylon scrub brush. Never pour water or spray liquids on the electronic console. Allow the treadmill to dry completely before using it.

Manually advance the running belt to clean the opposite side. Do not clean the belt while the running belt is moving. Liquid can splash onto the motor causing damage to the equipment and possibly injuring you.

The Precor Heart Rate Option equipment requires little maintenance beyond keeping it dust free and cleaning the chest strap with mild soap and water. Use a damp sponge or soft cloth to clean the chest strap. Dry the surface thoroughly with a clean towel.
