C846 SELF-POWERED FEATURES
The power source for the C846 is the user. When a person works out on the C846
and moves the foot pedals at a pedal speed above 20 revolutions per minute
(RPM), the power that is generated allows the C846 to function properly.
Informational displays appear when the battery is low or when the user has stopped
pedaling during a workout. The display provides minimal instructions to let you
know what to do to retain power. If the messages are ignored, the C846 will begin
shutdown procedures to maintain the charge of the battery. Refer to page 23,
Informational Displays Prior to Shutdown.
An optional battery recharger can be purchased and provides sustained power to
the C846. If you plan to customize your unit (refer to Club Settings section), the
optional battery recharger is highly recommended. To purchase the optional battery
recharger, check with your dealer.

page 13

SUPPLYING POWER TO THE C846
The C846 does not require an electrical power connection. It has an internal
battery that is recharged every time a user works out for a reasonable period of
time. A pedaling speed above 20 revolutions per minute must be maintained for
several seconds before the Precor banner appears on the display. Once the banner appears, the user can press QUICKSTART or ENTER to begin working out.
For more information, refer to page 29, Exercising on the C846.

TESTING THE HEART RATE DISPLAY
Verify that the heart rate display is operational before customers begin using the
machine.
1. Begin pedaling and maintain a pedaling speed above 20 revolutions per minute.
The Precor banner will appear on the display.
2. Grab both metal grips on the handlebars. See Diagram 8. A user must grasp both
handlebar grips before the receiver in the display acquires the heart rate signal.

Diagram 8

Hand placement on
the handrail grips.

Heart rate grip
C846 Recumbent

Note: To conduct electrical impulses from a user’s heart, the electrode strips
(handlebar grips) must be in contact with the user’s skin. Usually, the concentration of salts in a person’s perspiration provides enough conductivity to
transmit a signal to the receiver in the display console. However some people,
because of body chemistry or erratic heartbeats, cannot use the heart rate
touch-sensitive feature on the C846. A POLAR® chest strap may provide
better results. Refer to Obtaining Service on page 7.
3. Wait five to ten seconds. A number indicating your heart rate (beats per minute)
should appear in the small upper right display. Refer to Diagram 9 on page 16.
4. If the heart rate display appears, the cables are properly connected and the
heart rate feature can be a viable part of a user’s workout.
5. If the heart rate display does not appear, stop pedaling. Ask someone else to
try steps 2 and 3. If no heart rate number appears, refer to the Maintenance
section, Heart Rate Troubleshooting Tips for more information.
page 14

Club Information

CHANGING THE UNITS OF MEASURE
Two different units of measure can be selected, Metric or U.S. Standard. Make your
selection using the ▼▲ keys. Press ENTER once the correct unit is displayed.

SETTING A WORKOUT TIME LIMIT
You can limit how long a user works out by setting a duration between 1 and 240
minutes. You can also choose NO LIMIT, which allows the user to select a course
and work out indefinitely. (Note that the user must enter a workout time of “0”
using the numeric keys at the Enter Time prompt before he or she can workout
indefinitely.)
Important: If the club setting is NO LIMIT and the user enters “0” at the Enter
Time prompt, then the Remaining Time display does not appear when a user
works out. (An exception to this rule is the Weight Loss Course.)
Note: The workout time of any course accessed by pressing QUICKSTART, is
set at the Club limit. Refer to QUICKSTARTTM on page 28.
Use the ▼▲ keys to select a workout time limit. For example, if you set the workout
time limit to 20 minutes, the C846 allows users to specify a workout between 1 and
20 minutes. Users would not be allowed to specify a time longer than 20 minutes.
Take into account that the user will get an additional five-minute, cool-down period
appended to his or her workout, so adjust the time limit accordingly.

SETTING A PAUSE TIME LIMIT
Use the ▼▲ keys to set a Pause time limit between 1 and 120 seconds (two
minutes). Note that changes to the Pause time become effective only when the
power source for the C846 is the optional battery recharger. If no battery recharger
is connected and the pedal speed drops below 20 revolutions per minute, the
C846 moves into a thirty second shut down mode. Refer to page 23.
page 17

LIMITING THE RESISTANCE RANGE
After pressing ENTER to accept the Pause time limit, you have the option to
change the resistance range. The resistance range does not affect the number of
resistance settings (1 through 25) that are available to the user. It determines how
much resistance is felt at each resistance setting, and how big the step in resistance is from one resistance setting to the next.
The default resistant range is HIGH. It provides the full resistance available from
the cycle. When the resistance range is set to HIGH and a user chooses the highend resistance levels using the arrow keys, the cycle provides enough resistance
to simulate sprinting or hill climbing for users wishing to stand on an upright cycle.
It also provides enough resistance for elite riders that are capable of spinning at
high speed with high resistance.
The MEDIUM resistance range provides approximately two thirds of the resistance
that is available with the HIGH setting. The maximum resistance available (a user
chooses a resistance setting of 25) is reduced and the change, in resistance from
one resistance setting to the next, is reduced. Clubs may want to select the
MEDIUM range for recumbent cycles. Since users cannot stand on a recumbent
cycle, less resistance is needed by the average (non-elite) rider. The MEDIUM
range allows an average user more comfort. It allows them to use more of the
available resistance settings and make resistance changes in the preprogrammed
courses (Hill Climb and Cross Country) easier.
The LOW resistance range provides approximately one third of the resistance
that is available with the HIGH setting. The LOW range may be appropriate in
special situations where deconditioned users are anticipated, but the LOW range
is not recommended for the normal club environment.

page 18

CUSTOMIZING A COURSE
After pressing ENTER to accept the Resistance Range, the display prompts you
to customize the course profile that appears on the display. The blinking segment
or column indicates the portion of the course that you can change. The resistance
LED is lit and a number, indicating the resistance level, appears beneath the
course profile.
Note: If you wish to create a custom course for your club members, continue with
the instructions below. If you prefer to exit the Club Custom Mode, press ENTER,

The C846 Display
The C846 is designed so users can work out with minimal instruction or training.
The directions on the console and the prompts on the display will guide a user
through the entire workout session. Before the C846 is used, however, we recommend that you familiarize yourself with it so you can instruct your customers to
use it safely and effectively. This section provides an overview of the features
provided on the display console

FEATURES ON THE DISPLAY CONSOLE
Indicator lights show which feature is being displayed. When a user works out, the
display presents Time, Distance, RPM (revolutions per minute), and Calories.
Users can change what features appear on the display by pressing the CHANGE
keys.

Important: Because the C846 is self-powered, the displays do not appear until
the user maintains a pedal speed above 20 revolutions per minute. Note that
there is an exception to this rule. If power is being supplied through the optional
battery recharger, then pedaling is not required for the Precor banner to appear.
Refer to page 6, C846 Self-powered Features.
As a user exercises, the display console provides motivation by presenting
constant feedback about his or her progress. A brief explanation of each feature
on the display console appears in Diagram 11. Look on the next pages for a more
thorough explanation. If an error message should appear, call a Precor qualified
service technician or service center. Refer to Obtaining Service, on page 7.

SMARTRATE® DISPLAY
SmartRate®: A user must enter an age, during the course Setup prompts and wear
a POLAR® chest strap (or hold onto the Heart Rate grips on the handlebars), while
in a course program, before the blinking segment in the bar graph can show the
zone that his or her heart rate is in, either: Weight Loss or Cardiovascular. Refer to
page 37, The SmartRate® Feature.

Important: During a course, the pedal speed must be above 20 revolutions per
minute and a user’s heart rate must be above 40 beats per minute before the
SmartRate® segment begins to blink. A user must grasp both handlebars or wear
a POLAR chest strap.
HEART RATE: The heart rate display lets a user monitor his or her heart rate.
When a heart beat is detected, the number appears in the small upper right
display (refer to Diagram 11). See the Important note above and refer to The
Heart Rate Feature and Target Zones on page 36.

UPPER DISPLAY
The Precor banner and course profiles appear in the large center display (LED matrix).
Always start a workout at the Precor banner. During workouts, the course profile
appears in the center display and corresponds to the course that the user selects. As
a user proceeds through a workout, a blinking column indicates his or her position.

INFORMATIONAL DISPLAYS PRIOR TO SHUTDOWN
The C846 saves its battery charge by moving into a shutdown mode. Whenever
PEDAL FASTER appears on the display, the heart rate, SmartRate® and course
indicators turn off. If the user does not maintain a pedal speed of 20 revolutions
per minute, then a thirty-second shut down process begins.
When twenty-eight seconds remain, the upper display appears blank and all key
presses are ignored except RESET. The touch-sensitive heart rate features are
also ignored. If no pedaling occurs in the next eight seconds, a row of dots (that
correspond to the number of seconds remaining before the C846 shuts off)
appears in the upper display.
If the C846 is connected to a CSAFE master device, a slightly different scenario
occurs. When the number of seconds remaining before the C846 shuts off equals
ten seconds (instead of eight), the workout session ends. RESETTING appears
in the lower display while the C846 disconnects from the CSAFE master device.
All key presses are ignored. Pedaling has no effect on the display.

page 23

If the battery voltage is low or needs recharging, the words WARNING - LOW
BATTERY appear after the PRECOR banner. The C846 continues to function
even with a low battery, but user and course information is lost once the user
stops pedaling. Note that the Pause feature does not work.
When the battery voltage is low, changes to the resistance are ignored. When a
user attempts to change the resistance, LOW BATTERY appears on the display.
The course profile and calories calculations are not affected by the low battery
and continue to show the programmed changes as if the changes to the resistance
actually occurred.
Note: A sustained workout at the current resistance will help recharge the battery.
Or, plug in the optional battery recharger. Refer to the Maintenance section.

LOWER DISPLAY
Prompts appear in this display prior to a workout. A user addresses each prompt
using the numeric or keypad keys. Once the user begins pedaling and maintains
a pedal speed above 20 revolutions per minute, lights appear in the columns
below the window indicating which information is being displayed. A user can
highlight a particular feature by pressing the appropriate CHANGE key.
The following describes the information that can appear in the lower display.
TIME: During a workout, a time (0:00) display appears. Time appears in minutes
and seconds. However, should a user exceed 60 minutes (during a single workout), the Time display converts to hours and minutes. The Time display shows
how long a user has been working out. Even when a user enters the cool-down
period, the Time display provides the cumulative duration of the workout.
DISTANCE: The distance that you have traveled appears (00.00) once you begin
a workout. The distance is related to the user’s current speed. Distance appears
in 100th mile increments until you reach 99.99 miles in a single workout, then
miles increment by 10ths (100.0). Distance can appear in miles or kilometers. If
you wish to change the display, follow the instructions found in Changing the
Units of Measure.
RPM: Indicates the number of revolutions that the pedal completes per minute.
The value can range between 20 and 150.

Important: The self-powered C846 requires that a user maintain a pedal speed
above 20 revolutions per minute to function properly. PEDAL FASTER appears on
the display as a warning that the C846 is entering shutdown mode. Refer to
Informational Displays Prior to Shutdown.
CALORIES: Provides the cumulative number of calories being burned.

page 24

REMAINING TIME : Indicates the amount of time, in minutes and seconds (mm:ss),
that remain in the course. When a user enters a cool down period, the Remaining
Time resets to five minutes and begins counting down from there.
Note: If the club has set the Workout Time Limit as NO LIMIT and the user
inputs 0 using the numeric keys at the time prompt, then no information appears
in the Remaining Time field. See Setting a Workout Time Limit on page 17.
SPEED: The displayed value is an estimate of “linear speed” even though the
cycle is stationary. The value is determined by converting the user’s current RPM
and resistance settings into an estimate for miles per hour (or kilometers per
hour). Refer to Changing the Units of Measure.
METS: Displays the metabolic equivalents of the user’s current energy expenditure level. A MET’s level of 1 represents the body at rest. Note that when a user
reduces pedaling intensity, the MET’s value begins to drop toward zero because
the displayed information no longer corresponds to the user’s MET’s level.
WATTS: Indicates the amount of energy the C846 is currently generating and is
derived from the current resistance and pedaling speed.
SEGMENT TIME: In the Manual or preprogrammed courses, this display indicates the amount of time, in minutes and seconds (mm:ss) that remains in the
highlighted column (or segment) of the course profile before the next column
begins blinking. If the course being used is Interval or Weight Loss, then the
number appearing in this display indicates the amount of time that remains in the
current interval.
RESISTANCE: Displays the amount of resistance being applied to the pedals.
The RESISTANCE ▼ and ▲ keys let the user set a resistance between 1 and 25
which affects the amount of resistance applied by the brake. Once a course is
begun, a user can also use the numeric keys to designate the resistance. Refer
to Numeric Keys on page 27.
Note: A user can check the resistance (when it is not the chosen display) any time
during a workout by lightly pressing either RESISTANCE ▼ or ▲ key for less than
two seconds. Pressing the RESISTANCE ▼ or ▲ key for more than two seconds
causes the resistance level to change.
AVERAGE SPEED: The estimated “mid-point” in linear speed at which the user is
traveling even though the cycle is stationary. The displayed value relates to the
total workout time divided by the total accumulated distance. The average speed only
appears when a user selects it by pressing the appropriate CHANGE key.
CALORIES PER MINUTE: Indicates the approximate number of calories being
burned per minute.

page 25

KEYS ON THE DISPLAY CONSOLE
The C846 has an easy-to-use keypad that is activated by the slightest touch.
Remind users that they only need to apply gentle pressure to these keys.
Each key on the display console’s keypad provides specific functions. Numeric
keys (numbered 1, 2, 3,... through 0) let the user enter data in answer to the
display prompts and change the course profile or resistance level during a workout. The standard keys, CHANGE, RESET, COURSE CHANGE ▲▼,
QUICKSTART, RESISTANCE ▼▲, and ENTER, let the user enter data as well as
control his or her workout.
The following information explains the different uses of the keys from left to right.

If the optional battery recharger is not connected, the user needs to maintain
a pedal speed above 20 revolutions per minute before keypad entries can
occur. Refer to Informational Displays Prior to Shutdown on page 23.

•

The Setup prompts need to be answered using the numeric keys or by pressing
the ▼ or ▲ keys. Accurate entries are required or features such as
SmartRate® will not work properly.

•

Pressing ENTER selects the information being displayed.

•

Pressing QUICKSTART bypasses further selections and prompts the user
to workout in Manual mode. Default values apply (see QUICKSTART on
page 28). The SmartRate® display does not appear.

•

Pressing RESET returns to the Precor banner.

Numeric Keys (0 - 9): During a workout, a user can press the numeric keys to
change the resistance levels (1 to 25). Remember, if the numeric keys are used to
alter the resistance, the user needs to designate, within three seconds, whether he
or she is increasing (by pressing the RESISTANCE ▲ key) or decreasing (by
pressing the RESISTANCE ▼ key), the corresponding resistance level.
Note: When the user presses the numeric keys to change the resistance, the actual
setting appears on the display while the brake is being applied. If the user wishes to
halt the change, the appropriate RESISTANCE ▼ or ▲ key must be pressed. The
brake stops and the display shows the current level.
During the Setup prompts, a user can also use the numeric keys to type in a
course number (1 through 14), workout time, weight, and age. Note that he or she
must press ENTER to process the selection.
CHANGE: During a workout, the CHANGE key lets a user choose which feature
appears on the display.
RESET: While answering the Setup prompts or during a workout, a user can cancel
the course program, clear the display, and return to the banner by pressing RESET.
COURSE CHANGE ▲▼
▲▼: During a workout, the COURSE CHANGE ▲▼ keys let
the user switch to a different course. When a user taps a COURSE CHANGE ▲▼
key, the course number and name appearing on the display corresponds to the
current course selection. When a user presses and holds a COURSE CHANGE
▲or ▼ key for a few seconds, the course number and profile changes. The user
can also choose a new course using the numeric keys. For more information,
refer to Selecting a New Course During a Workout on page 34.

Important: The COURSE CHANGE keys are disabled in the Weight Loss course
and Fitness Test. If a user starts working out and selects the Weight Loss course
or the Fitness Test, he or she cannot “change” to another course. The opposite is
also true. The C846 does not allow any mid-course changes to or from the Fitness
Test or Weight Loss course.
RESISTANCE ▼▲
▼▲: During a workout, the RESISTANCE ▼▲ keys let the user
decrease or increase the force applied against his or her pedaling. The display
can show a range from 1 to 25. Setting 1 provides the least resistance.
When a user changes the resistance by pressing the RESISTANCE ▼ or ▲ key,
the number that appears on the display shows the target resistance (not necessarily, the present resistance being applied) because the display can change quicker
than the brake application.
Another feature of the RESISTANCE ▼▲ keys lets the user review the C846
resistance any time during a workout. If RESISTANCE is not one of the chosen
features being displayed, a user can view the actual resistance by lightly touching
either RESISTANCE ▼ or ▲ key. The user can opt to change the resistance if the
key is held down or touched again within two seconds. Note that the numeric keys
can also be used to adjust the resistance.

Continue pedaling. Adjust
resistance by touching
RESISTANCE ▼or ▲.
Pause

To pause during your workout session, stop pedaling for a
few seconds. Be aware that if the optional battery recharger
is not attached, you have only thirty seconds before the
C846 shuts off. See Pause, Cool Down and Exit Features.

Complete the course
and cool down.

5. When you have completed a course that has a limited duration, a five-minute, cool-down period automatically begins.
Note: During cool down, if you wish to continue working out,
touch a COURSE CHANGE ▲▼ key and select a new course.
Your workout statistics carry forward to the new course.

Continue pedaling while
reviewing the final
workout statistics.

6. When the cool-down period ends, the WORKOUT SUMMARY banner appears. If you wore a POLAR® chest strap or
held onto the handlebar grips during your workout, a heart
rate analysis follows the banner and displays:
• the average heart rate during your workout
• the maximum heart rate during your workout
• the duration that your heart rate was in the Weight
Loss or Cardiovascular zones.
Workout statistics except TIME, DISTANCE and CALORIES
reset to zero. (TIME shows the accumulated workout time
including warm-up and cool-down periods.)

Stop pedaling.

7. Stop pedaling to end your workout.
page 31

COOLING DOWN AFTER A WORKOUT
Cooling down is an important aspect of your workout because it helps reduce
muscle stiffness and soreness by transporting excess lactic acid out of the working muscles. Cooling down for at least three minutes helps provide a smooth
transition that allows your heart rate to return to its normal (non-exercising) state.
The C846 automatically initiates a five minute, cool-down period once you complete a course that has a specified time duration. A prompt appears, indicating
that you are in cool down.
During your cool down, the workout statistics continue to appear. The TIME display
shows the accumulated time which includes warm-up and cool-down periods. When
you complete the five minute cool down, a WORKOUT SUMMARY appears. See
the information below.

Important: To activate a cool-down period, a course must “end.” The course ends
when the workout time (entered during the Setup prompts) expires. If no workout
time entry occurred or the time entered was zero, then (from a software perspective) no time limit exists, so a cool-down period is not appended to the course.
(Note that club time limits do apply whether or not a workout time was entered.)

PAUSE, COOL DOWN AND EXIT FEATURES
Pausing, cooling down, and exiting are integral parts of your workout. The C846
goes through several prerequisites before actually exiting a course. The following
tables explain the various situations. Since the C846 is self-powered, pedal movement must be continuous to avoid shutdown mode. For more information, refer to
page 23.
Note: If the optional battery recharger is supplying power to the C846, the factory
setting for Pause mode is two minutes (120 seconds). The club has the option to
change the setting. A duration can be set between 1 and 120 seconds and limits
how long a user can pause his or her workout. Refer to Setting a Pause Time Limit
on page 17.

While the new course selection appears on the display, you have two options:
press QUICKSTARTTM or press ENTER.
Option 1: Press QUICKSTARTTM if you wish to continue your workout without
any further prompts appearing on the display. All the aspects from the previous
course (workout time, statistics, weight, age, etc.) are carried forward. SmartRate®
will be active as long as it appeared during your initial workout. The workout time
may be limited per the overall club time limit.
Option 2: Press ENTER if you wish to continue your workout, but want to add
aspects that may not have been part of your initial course such as, weight and
age. The C846 reacts as if you are starting a new workout and Setup prompts
appear requesting information. Once the Setup prompts are answered, workout statistics, from the previous course, are carried forward. If your age is
entered, SmartRate® will be active. As with QuickStart, the workout time may
be limited per the overall club time limit. Refer to Club Information on page 15.

Once the user reaches the club time limit in the second course selection, the COURSE
CHANGE keys are disabled. Note that users cannot use the COURSE CHANGE
keys to select a different course if one minute or less remains before the club time
limit expires.

COURSE FEATURES
•

If the club allows it, you can work out indefinitely in any course (except
Weight Loss). At the workout time prompt, select INFINITE by pressing the
zero on the numeric keypad.

Important: The automatic cool-down period is not appended to courses where
the duration is INFINITE.
•

Place a time limit on any course during the Setup prompts. At the workout
time prompt, indicate the duration of your workout. When you complete the
course, the automatic cool-down period begins.

•

Determine the pedal resistance as you move through the course.

•

SELECT preprogrammed courses that provide preset resistance levels. In
several courses, the resistance levels automatically change as you progress
through the course profile. You can override the resistance using the RESISTANCE ▲ or ▼ keys for each upcoming segment in the course profile. The
profile changes accordingly and the resistance position is saved until a different course is used. When you complete a preprogrammed course, the automatic cool-down period begins.

•

The progress that you make during a course is tracked by a blinking cursor.
If the column is several segments high, the entire column blinks.

•

Access heart rate and SmartRate® capabilities when the user wears a POLAR®
chest strap or holds onto the handlebar grips during a workout. Note that
the SmartRate® indicator lights do not appear if QUICKSTART is pressed at the
PRECOR banner.

The different course names appear on the following pages along with a description of the course features. Refer to Diagram 16 on page 38.

page 35

THE HEART RATE FEATURE AND TARGET ZONES
To use the heart rate features, you must wear a POLAR® chest strap or grasp
both grips on the handlebars while working out. A transmitter sends your heart
rate signal to the receiver installed in the display console. The signal appears as
your pulse rate on the display. During your workout, the heart rate indicator lights,
begins blinking and then, displays your heart rate. This lets you see what your
heart rate is doing even when the display is presenting other workout statistics.

YOUR AGE
Diagram 15 illustrates the ideal target zones for your age. Use the chart as a
guideline. Always check with your physician and verify what your appropriate
heart rate target zone should be for your age, height, weight and physical fitness.
Note: The SmartRate® display does not appear if you use the QUICKSTART key
to access a course. Refer to QUICKSTARTTM on page 28.
Important: The POLAR® chest strap is optional equipment and can be purchased
through your dealer. The grips on the handlebars are factory installed.

page 36

THE SMARTRATE® FEATURE
Add the benefit of SmartRate® to every course on the C846. Using SmartRate® as
a visual cue helps you adjust your exercise routine to suit specific needs.
SmartRate® simplifies the correlation between heart rate and exercise. You don’t
have to stop concentrating on your workout to find your pulse. It is displayed right
in front of you along with the SmartRate® zone. Once you begin a course, a
blinking segment in the bar graph appears on the left of the display (if you entered
your age during the Setup prompts). The blinking segment indicates the zone that
your heart rate is in: Weight Loss or Cardiovascular.

Important: Access to SmartRate® is only available when the person exercising
wears a POLAR® chest strap or uses the grips on the handlebars. (The POLAR®
chest strap is a separate purchase option.) The SmartRate® indicator lights do
not appear when QUICKSTART is used to select a course.
However, if SmartRate® is active during your workout then it remains active even
though your course selection may change. For example, during a workout you
decide to select another course by touching the COURSE CHANGE ▲▼ keys.
You press QUICKSTART (instead of ENTER) to continue your work out in the new
course. If SmartRate® was active during the initial course selection, it continues to
appear on the display.
Weight Loss Zone
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 85% of your maximum aerobic heart rate or go above your training zone. Refer to Diagram 15 for
your appropriate target zone.
Cardiovascular Zone
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. Maintaining your heart rate in either zone (weight loss or cardiovascular) for 30 minutes or more on a regular basis (minimum three times a week)
provides the greatest benefits.

page 37

Diagram 16 C846 Courses.

MANUAL MODE AND THE QUICKSTARTTM KEY
Manual mode lets you set the resistance level. As with other courses, when you
complete the time limit set for the course, the automatic cool-down period begins.
Note: If a user is allowed to choose “INFINITE”, then no time limit is set and no
automatic cool-down period exists.
You can choose Manual mode in two different ways:
•

pressing the QUICKSTART key at the Precor banner. QUICKSTART bypasses the remaining selections and starts the Manual course. Default values includes the club’s time limit, a weight value of 150 lbs. (68 kg.) and an
age of 0. The SmartRate® display is inactive.

•

pressing ENTER at the Precor banner. This causes the C846 to display several Setup prompts. When #1 — Manual Time Goal appears on the display,
press ENTER.

The Manual course profile initially appears as a flat line. Use the RESISTANCE
▼▲ keys or the numeric keys to adjust the resistance level. (See page 27 for
more information.) As you proceed with your workout, a blinking column represents your position on the course.

CROSS COUNTRY AND HILL CLIMB COURSES
The Cross Country and Hill Climb courses consist of alternating segments of preset
resistance levels. The course profile is divided into segments. The height of each
segment reflects the changes in resistance levels. Though the resistance is preset,
you can override it during the course, by pressing a RESISTANCE ▲ or ▼ key.
page 38

RANDOM COURSE
Every time a Random course is selected, a different course profile appears. The
segments that appear in the course profile maintain a set resistance that you can
override using the RESISTANCE ▼▲ keys. The resistance is preset to 1 for the first
segment. The maximum change allowed between segments is plus or minus 4 resistance levels. If the club lets you set the workout time at INFINITE (number zero on
the numeric keypad), you need to incorporate a cool down period into your workout.

INTERVAL COURSE
The Interval course is one of the best for conditioning your cardiovascular system.
The course is designed to raise and lower your heart rate in a repeating fashion for a
specified period of time. The three interval courses on the C846 let you select the rest
and work intervals according to your training regimen. In the 1-3 interval course, each
1-minute rest interval is followed by a 3-minute work interval. In the 1-2 interval
course, each 1-minute rest interval is followed by a 2-minute work interval. In the 1-1
interval course, each 1-minute rest interval is followed by a 1-minute work interval.
The resistance levels are preset at 1 for the rest interval and 3 for the work
interval. At any point during the workout, you can change the settings of the
current interval by simply pressing the RESISTANCE ▼▲ or number keys. The
software remembers the new settings and applies it to the appropriate rest or
work interval throughout the remainder of the course.
Each time the C846 changes intervals, it informs you by displaying a message.
When you complete the time limit set for the course, the automatic cool-down
period begins.

Important: If you entered your Age during the Setup prompts and wear the POLAR®
chest strap or utilize the heart rate grips, you can adjust the rest or work intervals to
keep your heart rate in its recommended zone. For the weight loss mode, 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.
See Diagram 15 on page 36.

WATTS CONTROL COURSE
On the C846, watts indicates the amount of energy the C846 is currently generating and is derived from the current resistance and pedaling speed. The Watts
Control course affects the user in that it keeps the level (as measured in watts) of
the user’s expenditure in energy fixed or constant. When a user selects the Watts
Control course, an initial target of 50 watts is preset. As the user pedals, the
pedal resistance changes to keep the energy expenditure stable at a constant 50
watts. The faster the user pedals (higher RPM), the lower the resistance. If a user
pedals slowly, a higher pedal resistance occurs.
A user can change the watts level by touching the RESISTANCE ▼▲ keys or
pressing the numeric keys followed by the appropriate ▼ or ▲ RESISTANCE key.

page 39

HEART RATE CONTROL COURSE
Once you complete the warm-up period and achieve your target heart rate, the
Heart Rate Course monitors your heart rate and automatically maintains it within
a few beats per minute (bpm) of the selected target. Lights on the SmartRate® bar
graph appear to show the “zone” that you are in.
Note: For the C846 to detect a heart rate, you must grasp the handlebar grips or
wear the POLAR® chest strap during a workout.
The handlebar grips or chest strap transmits your heart rate signal to the receiver
that is installed in the display console. During your workout, the heart rate indicator
lights which lets you see what your heart rate is doing even when the display is
presenting other workout statistics.
To use the Heart Rate Course follow the steps found in Quick Steps to Working
Out on page 31 and choose #9 — Heart Rate Control as the course.
Note: If your heart rate moves into the heart rate zone for your age during the three
minute warm-up period, the warm-up period ends and the Heart Rate Course begins.
CAUTION: A warning message will appear if you go above your maximum
recommended heart rate target zone. Heed the warning and get permission
from your personal physician before working out above the maximum
recommended zone for your age and fitness level. See Diagram 15 for the
recommended target zones.

WEIGHT LOSS COURSE
The Precor Weight Loss course 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 and it is designed to help you burn the
most fat during a 28-minute workout, while minimizing the risk of discomfort and
injury. The Weight Loss program is similar to the Interval course, but the intervals
are set at four minutes. If you use the heart rate grips on the handlebar or wear
the POLAR® chest strap, try to keep the rest interval’s target heart rate at 55% of
(220 minus your age), while the work interval should be set to 70% of (220 minus
your age). As in the Interval course, once you set the resistance levels for the
first rest and work interval, the C846 automatically repeats the interval settings
throughout the course.
Note: When you complete the 28-minute time limit set for the course, the automatic cool-down period begins.

RESISTANCE CUSTOM COURSE
A custom course is available on the C846 where the resistance is preset by the club.
Though the resistance is preset, a user can adjust the settings during a workout by
touching the RESISTANCE ▼▲ keys. Once the course ends, it reverts back to the
custom resistance levels set by the club. Refer to Limiting the Resistance Range on
page 18 and Customizing a Course on page 19.
page 40

GOAL-BASED COURSES
These C846 courses (Distance Goal and Calorie Goal) are similar to the Manual
course except that the user’s position and course duration are based on a “distance” or “calorie” goal. You can use the numeric keys or the RESISTANCE ▼▲
keys any time during the course to change the resistance. When you complete
the goal set for the course, the automatic cool-down period begins.
Note: A club time limit may exist for these courses. A prompt appears on the
display if the club time limit is reached before the goal. Refer to Club Information.

FITNESS TEST
The Fitness Test (course number 14) provides a means of determining your fitness score. The algorithm used to create this course was developed by Dr. Neil
Gordon of the Cooper Clinic.
The Fitness Test determines heart rate response to varying levels of exercise. It
measures the maximum amount of oxygen the body can use for energy production
during exercise. The higher the amount of oxygen that your body can use, the greater
your ability to exercise for prolonged periods of time. You can use the results of the
Fitness Test to personalize a weight loss fitness regimen to meet your needs.

FITNESS TEST GUIDELINES
Before selecting the Fitness Test, read the following guidelines:
•

Sit and rest for at least five minutes prior to taking the test. This brings your
heart rate to a resting state.

•

You must wear the POLAR® chest strap and complete at least two of the six
stages of the test before a fitness score can be achieved and presented.

•

The fitness score is affected by your weight and age. Be sure to include this
data during the Setup prompts.

•

Let the test adjust the pedal resistance for you. However, if you need to stop
pedaling to regain control or reduce your heart rate, please do so — you can
retake the Fitness Test later.

•

The RESISTANCE ▼▲ keys are disabled during the test.

•

The number of two-minute stages that you complete is determined by the
cycle’s software and is dependent on your level of fitness. Do not be alarmed
if you do not complete all six stages; this is normal. However, you must
complete at least two stages to receive a fitness score.

•

When you finish the Fitness Test, the pedal resistance is reduced. No automatic
cool-down period is appended to the test.

•

Create your own cooling down period by pressing the RESISTANCE ▼▲ keys
to regulate the brake and return your heart rate to a normal, restful state.

page 41

The Fitness Test ends if any one of the following occurs:
•

you stop pedaling.

•

your heart rate rises and remains for one-minute above the maximum allowable heart rate (220 minus your age). Refer to Diagram 15.

•

your heart rate increases during the first stage and climbs above 85% of the
maximum allowable heart rate (220 minus your age). See Diagram 15.

•

your heart rate remains at or above 80% of the maximum allowable heart
rate (220 minus your age) in any subsequent stages.

•

your heart rate cannot be detected or is no longer being transmitted.

•

you complete all six stages of the test.

FITNESS TEST SCORES
When a valid score is obtained it appears in the display. Tables 1 and 2 show the

Maintenance
The self-powered C846 will continue to run smoothly and efficiently as long as you
maintain it. You are responsible for cleaning and maintaining the unit’s integrity. If
you fail to maintain the C846 as described below, it could affect or void the Precor
Limited Warranty.

DANGER — To reduce the risk of electrical shock, always unplug the
C846 from the optional battery recharger before cleaning or performing any
maintenance tasks.

INSPECTION
Perform a daily inspection of the unit. Look and listen for loose fasteners,
unusual noises, and any other indications that the equipment may be in need of
service. Obtain service should you notice any of the above.

Important: If you determine that the C846 is in need of service, move it away
from the main workout area and place an large “Out of Service” sign on it.
To order parts or to contact a Precor authorized service provider in your area,
refer to Obtaining Service on page 7.

CLEANING THE EQUIPMENT
Most of the working mechanisms are protected inside the casing. However, for
efficient operation, the C846 relies on low friction. To keep the friction low, the
C846 pedals and internal mechanisms must be as clean as possible.
v To clean all exposed surfaces on the C846, it is recommended that you use
a diluted solution of mild soap. Clean the C846 everyday with a soft cloth,
dampened (not dripping wet) in the solution.
CAUTION: Do not use any acidic cleaners. Doing so will weaken the
unit’s coating and void the Precor Limited Warranty. Never pour water
or spray liquids on any part of the C846. Allow the C846 to dry completely
before using.
v Periodically, clean the grooves on the foot pedals using a soft nylon scrub
brush. Vacuum the floor underneath the unit to prevent the accumulation of
dust and dirt.
v The Precor Heart Rate equipment requires little maintenance beyond keeping it dust free. Dampen a sponge or soft cloth in mild soap and water to wipe
the touch-sensitive grips on the handlebar or to clean the POLAR® chest
strap. Dry the surface thoroughly with a clean towel.

STORING THE POLAR® CHEST STRAP
Store the chest strap transmitter in a place where dust and dirt cannot accumulate on it such as, a closet or drawer. Be sure to keep the chest strap protected
from extremes in temperature. Do not store it in an area that may be exposed to
temperatures below 32 degrees Fahrenheit.

page 43

ADJUSTING THE SEAT’S SIDE TO SIDE MOVEMENT ON THE
C846 RECUMBENT.
Periodically check the seat on the C846 Recumbent. Take the following steps to
eliminate any side to side rocking movement:
1. To determine if the seat rocks side to side, straddle the base with your feet
firmly planted on the floor.
2. Sit on the seat and face the display console. Gently, move your upper body
side to side. If the seat rocks side to side with you, you need to “realign” the
center wheels that run underneath the seat. Adjustment bolts are located on
the both sides of the seat rail.
To realign the seat’s center wheels, take the following steps:
1. Obtain a 3/16-inch and 5/16-inch hex key.

Diagram 17 Adjusting the
wheel locks.

Adjustment plate
Loosen
adjustment bolts
Wheel lock
adjustment key

2. Start on one side of the cycle and loosen the two adjustment bolts with the 3/
16-inch hex key as shown in Diagram 17.
3. Using a 5/16-inch hex key, turn the wheel lock adjustment key clockwise
1/4 turn. This thrusts the center wheel up inside the top rail. Continue
holding the hex key in place while you tighten the adjustment bolts with
the 3/16-inch hex key.
4. Remove the hex keys and perform step 3 on the opposite side of the seat.
5. Check that the seat no longer rocks from side to side. If rocking movement
continues, you may need to repeat the process.

page 44

SERVICING THE C846 AND LONG TERM STORAGE
Do not attempt to service the C846 yourself except for the maintenance tasks
described in this manual. The unit does not contain any user-serviceable parts
that require lubrication. For information refer to Obtaining Service on page 7.
When the C846 battery recharger is in use, ensure that the power supply cord does not
create a safety hazard by keeping it out of the way of traffic and moving parts. If the
power supply cord or power conversion module is damaged, it should be replaced.
When the C846 is not in use, ensure that the battery recharger cord is unplugged from
the wall outlet and is positioned so that it will not become damaged or interfere with
other equipment or people. Ensure that is kept free from dirt, moisture, or damage.

USING THE OPTIONAL BATTERY RECHARGER
If no one has used the C846 for an extended period of time, the battery may need
recharging. Symptoms of a low battery include:
• a flickering or erratic display
• no workout statistics appear or accumulate
• changes to the resistance are ignored
Note: The optional battery recharger can be connected or a sustained workout
may help recharge the battery. Refer to page 23, Informational Displays Prior to
Shutdown.
Diagram 18 shows the receptacle for the optional battery recharger. Plug the opposite end into the appropriate power source for your unit (110/120v or 220/240v). You
can use the C846 while the battery recharger is plugged in. The display functions a
bit differently when the battery recharger is used. It returns to the Precor banner
instead of appearing blank when a user stops working out.

HEART RATE TROUBLESHOOTING TIPS
A few easy steps can be taken before you need to call customer support regarding heart rate problems. One of the first things to do is verify the following:
❑

A POLAR® chest strap is being worn properly by the user during a workout.
Or, the user is placing both hands on metal grips found on the handlebars.

❑

The user is pedaling above 20 RPM.

❑

The user is working out in a selected a course. (The Heart Rate feature is
activated when a course profile appears.) Note that if the user presses
QUICKSTART to access a course, the SmartRate and heart rate features will
not appear.

Other aspects of the heart rate option are discussed below:
Detecting a Heart Beat
It may take several seconds for the heart rate receiver to detect a number of valid
heartbeats. Once it does, the user’s heart rate is displayed when the Heart Rate
indicator (LED) is lit during the scanning process.
If “— — —” appears when the Heart Rate indicator (LED) is lit and all the previously discussed steps have been taken, then you need to do the following:
Touch-sensitive heart rate
• to conduct electrical impulses from a user’s heart, both touch-sensitive grips
(metal strips) must be in contact with the user’s skin. Usually, the concentration of salts in a person’s perspiration provides enough conductivity to transmit a signal to the receiver in the display console. However some people,
because of body chemistry or erratic heartbeats, cannot use the heart rate
touch-sensitive feature on the C846. A POLAR® chest strap may provide
better results. Refer to Obtaining Service on page 7.
POLAR chest strap
• Make sure that the electrodes on the chest strap are moist and placed properly against the skin. Sometimes, due to body chemistry, the chest strap
cannot successfully detect and transmit a heart rate. If this occurs, use the
electrolyte spray that accompanies the Precor Heart Rate Option package.
Follow the directions on the bottle. After spraying the electrode strips on the
chest strap, check to be sure that the strap is comfortably tight around the
chest and centered in the middle of the user’s chest.
• Another possibility which can cause erratic readings is that the chest strap’s
battery may be dead. To purchase a new chest strap, refer to Obtaining
Service on page 7.
