12 Operating and Maintaining the P20 Console

Chapter 1

Getting Started

The P20 console offers administrators and members the
ability to set defaults that meet their specific needs.

Activating the Console for Self-Powered
Equipment

Precor equipment is either self-powered or externally
powered using an optional power adapter. Self-powered
equipment requires the user exercise to initialize the console.
This section provides more detail about powering equipment.

Activating the Console for Self-Powered Equipment

On self-powered equipment, when a user starts exercising,
the console initializes and displays the Welcome banner. A
minimum rate of motion must be maintained for the
Welcome banner to appear. The words PEDAL FASTER (or
the equivalent message depending on the equipment type)
appear in the display when the rate of motion drops below the
minimum requirements.

The equipment saves its battery charge by moving into a
shutdown mode. If the user does not maintain the minimum
rate of motion, a 30-second shutdown process begins.

In this mode, the console displays a countdown indicator and
ignores all keypresses. If no movement is detected or the rate
of motion remains below the minimum, the indicator changes
as the countdown continues.

Note: The user can resume exercising before the countdown
period elapses and the program will continue from the point
at which it was paused.

14 Operating and Maintaining the P20 Console

Optional Use of the Power Adapter

An optional AC power adapter provides sustained power to
the equipment. This adapter allows you to change settings
without having to pedal the equipment. To purchase the
power adapter, contact your dealer.

If you purchase the optional power adapter, you must also
purchase the internal cable kit. The kit supplies the cable,
bracket, and fasteners that connect the power adapter to the
lower electronics board.

CAUTION: The internal cable kit must be installed by authorized
service personnel. Do not attempt installation on your own as you
could void the Precor Limited Warranty. For more information,
refer to Obtaining Service.

Important: If this equipment includes a P80 console, the optional
power adapter and the internal cable kit must still be installed to
provide continuous power to the base unit and support its internal
battery.

Once the internal cable kit is installed, you can plug the
optional power adapter into the equipment. Plug the opposite
end into the appropriate power source for your equipment
(120 V or 240 V). Review the safety instructions found at the
beginning of this manual before using the power adapter.

CAUTION: When the optional power adapter is in use, make sure
that the power supply cord does not create a safety hazard. Keep
it out of the way of traffic and moving parts. If the power supply
cord or power conversion module is damaged, it must be replaced.

The control console functions differently when the power
adapter is connected. Because the power adapter provides a
constant source of power, a user can pause for brief periods
without initiating shutdown procedures. When the pause time
limit expires and the user has not resumed exercising, the
console returns to the Welcome screen. The default pause
time is 30 seconds for all fitness equipment. Refer to the
manual for your control console for instructions on setting or
changing the pause time limit.

Chapter 2

Setting Up the Console

Use the System mode to configure settings in ways that
benefit your users and your facility. The System menu is
visible only to administrators and registered service
technicians. Changes made to these settings are saved to the
fitness equipment.

The system settings are:

 Odometer Settings
 Club Settings

 Important Safety Instructions
 Getting Started
 Using the Safety Clip (for treadmill only)

Using the Touch Heart Rate Feature

Note: Touch heart rate performance may vary based on a
user’s physiology, fitness level, age, and other factors. You
may experience an erratic readout if your hands are dry, dirty,
or oily, or if the skin on your palms is especially thick. Wearing
hand lotion can also cause an erratic readout. In addition,
make sure that the sensors are clean to ensure proper contact
can be maintained.

28 Operating and Maintaining the P20 Console

To use the touch heart rate feature, place the palm of your
hands directly on the metal heart rate sensors on the
equipment’s handlebars. To ensure a more accurate heart
rate readout, make sure you follow these tips:

 Both hands must grip the sensors for your heart rate to

register.

 It takes a number of consecutive heart beats (15-20

seconds) for your heart rate to register.

 When gripping the sensors, do not grip tightly. Keep a

loose, cupping hold. Holding the grips tightly can affect
the reading.

 As you work out, your perspiration will help transmit your

heart rate signal. If you have difficulty using the handheld
grips to determine your heart rate, try the sensors again
later in the workout to see if you can obtain a heart rate
signal.

 If the touch heart rate feature does not work for you,

Precor recommends that you use a chest transmitter
strap.

Figure 5: Heart rate target zones

CAUTION: Your heart rate should never exceed 85% of your
maximum aerobic heart rate. Your maximum heart rate is equal to
220 minus your age.

Introducing Users to the P20 Console 29

Using a Chest Strap Transmitter

WARNING

Signals used by the Chest Strap Transmitter
(or heart rate strap) may interfere with
pacemakers or other implanted devices.
Consult your physician and the manufacturers
of your Chest Strap Transmitter and
implanted device before using a Chest Strap
Transmitter.

Wearing a chest strap transmitter during your workout
provides steady heart rate information. For the equipment to
detect your heart rate, you must grip the touch heart rate
sensors or wear a chest strap transmitter while exercising. In
the presence of both touch and wireless data, the touch data
takes precedence and will display.

Note: To receive an accurate reading, the strap needs to be in
direct contact with the skin on the lower sternum (just below
the bust line for women).

To use a chest strap transmitter:

1. Carefully dampen the back of the strap with tap water.

Important: Do not use deionized water. It does not have the
proper minerals and salts to conduct electrical impulses.

2. Adjust the strap and fasten it around your chest. The
strap should feel snug, not restrictive.

3. Make sure that the chest strap is right-side-up, lies
horizontally across, and is centered in the middle of your
chest.

4. Test the chest strap placement by checking the heart rate
function on the equipment. If a heart rate is registering,
your chest strap placement is correct. If the equipment
does not register a heart rate, readjust the strap and
recheck the heart rate function.

Treadmill Auto Stop™ (Automatic Stop)
Function

Important: The default setting for this feature is ON. An
administrator can turn off this feature in the System Settings;
however, Precor recommends it remain ON.

The Auto Stop™ (Automatic Stop) feature is designed to
bring the treadmill to a gradual stop when it is not in use. This
might occur if a user steps off the treadmill before the end of
a workout and leaves the treadmill running.

Sixty seconds after a treadmill workout starts or resumes, the
equipment begins Auto Stop monitoring. If a user is detected,
then no message appears, and the selected workout
continues.

32 Operating and Maintaining the P20 Console

If no user is detected after an additional 30 seconds, the
console displays the message NO USER DETECTED,
STOPPING IN 10 SECONDS as notification of the pending
stop. During the display of this message, a ten second
countdown begins. If a user does not override the countdown,
the belt comes to a gradual stop after the countdown is
complete.

Note: Users weighing more than 90 pounds (41 kg) are
detected within the speed and position limits of the feature.
Users weighing 50 pounds (22.7 kg) to 89 pounds (40.5 kg)
may not be detected depending on their speed and location.
Always be aware of and follow the console’s instructions for
proper operation.

Using SmartRate®

The Precor SmartRate® technology is a precise, easy-to-read
heart rate monitor that helps users achieve their best
personalized workouts. SmartRate displays actual heart rate
information in relation to the user’s target zone for weight
loss and cardiovascular training. This feature is visible during
all workouts. In addition, some equipment includes a Heart
Rate Control (HRC) workout that automatically adjusts
intensity to keep a user’s heart rate in its target zone. For
more information, refer to Programs.

CAUTION: Before beginning any fitness program, see your
physician for a thorough physical examination. Seek advice from
your physician to learn the target heart rate appropriate for your
fitness level.

To test your heart rate:

1. Begin a workout by pressing QUICK START, or by
selecting a preset workout followed by pressing GO.

2. Grasp the handheld heart rate sensors with both hands.
Depending on the type of equipment, the letters "Hr"
appear, or a blinking heart displays while the equipment
reads your heart rate. After a few moments, your heart
rate displays in beats per minute. The blinking segments
in the SmartRate field indicate the current zone of your
heart rate: Warm Up, Fat Burn, Cardio, or High.

Programs

Preset workouts are a great way to tailor your workouts to
your fitness goals, stay challenged, and add variety to your
sessions. In the following figures, the elevated areas show the
work expenditure for each preset program.

Manual

In this program, resistance and speed changes are completely
under your control. The profile is initially a flat line. Any
increase or decrease made in one program segment will
increase or decrease all remaining portions by the same
amount.

Figure 8: Manual

40 Operating and Maintaining the P20 Console

Interval 1-1 and Interval 1-2

The Interval programs are primarily for conditioning your
cardiovascular system. These programs are designed to raise
and lower your heart rate in a repeating fashion for a
user-defined period of time by alternating rest and work
intervals. Program intensity is adjustable.

Figure 9: Interval 1-1

Figure 10: 1-2 Interval

Weight Loss

The program time is fixed at 28 minutes. The program
consists of four intervals, each lasting eight minutes. You can
change the resistance at any time during the work interval.

Figure 11: Weight Loss

Programs 41

Basic Heart Rate Control

This program computes your target heart rate based on the
calculation, 60% of 220 minus your age. The equipment
adjusts resistance and/or incline to maintain your target heart
rate while you work out.

When a heart rate signal is not received, a heart shape with a
question mark appears in the upper text display. Recheck your
hand grip on the handheld sensors or the placement of your
chest strap.

Figure 12: Basic HRC

Note: For the unit to detect your heart rate, you must grip the

handheld heart rate sensors or wear a chest strap while
exercising. In the presence of both handheld and wireless
data, the handheld data takes precedence and displays.

Hill Climb

This preset program simulates hill climbing. The program is
fixed at 30 minutes on most equipment, and the resistance is
predetermined. Any increase or decrease made in one
program segment will increase or decrease all remaining
portions by the same amount.

Figure 13: Hill Climb

42 Operating and Maintaining the P20 Console

Cross Country

The purpose of the preset program is to simulate an outdoor
running experience. In this case, you can change the overall
profile or intensity of the program (resistance) at any time;
however, you cannot change the shape of the preset "hills"
and "valleys" you see depicted on the display.

Figure 14: Cross Country

Random

Every time this program is selected, a different program
profile appears. The one-minute segments that appear in the
program profile maintain a set resistance that you can
override. The Random program has a default time limit, or you
can press STOP to complete your program sooner.

Aerobic

This program is similar to an Interval program. You can set a
length of time for your fitness session and you can specify the
speed and the incline or resistance.

Breaking in the Equipment

Precor equipment does not require an actual break-in period.
However, moving components such as belts, gears, and
bearings can settle while the equipment is being stored or
shipped. This can cause the equipment to operate with a
small amount of roughness or noise when it starts up for the
first time.

The equipment usually returns to smooth operation after a
day or two of normal use. If it does not, contact your dealer
for assistance. For more information, refer to Obtaining
Service.

Chapter 2

Installing the Console

To make installation easier, all Precor Experience Series
consoles use the same mounting hardware and connector
locations whenever possible. The installation sequence for
any of them is as follows:

 Threading the cable assembly
 Connecting cables
 Completing the installation (tightening the mounting

screws and attaching the back cover)

The following sections describe how to perform these tasks.

Threading the Cable Assembly (P80)

Earlier in the installation, you threaded the necessary cables
through the frame of the base unit and out the passthrough
opening in the console mount. As you line up the back plate
on the console with the console mount, you must make sure
that the cable assembly passes correctly through the
openings in both components.

34 Assembling and Maintaining Elliptical Fitness Crosstrainers: EFX 883 / 833 / 823
