The M5 computer is a powerful teaching and programming tool. The computer can
assist both the instructor and participant by providing immediate feedback as well
as tracking on-going improvement. By experiencing objective Cadence, Power
Output, Gears and Heart Rate, the participant benefits from a better overall and more
effective workout. The computer can also be used as a motivating tool to engage
participants in their workouts. The more participants understand the components of
a proper workout, the further they can fine tune their performance. The goal is to work
more effectively and efficiently, and achieve better results.
Line 1 RPM (Cadence) -
The RPM displays the participants speed or Revolutions
Per Minute of the Strider’s footpad. RPM is also known as Cadence and is roughly the
speed at which the participant is striding. At above 140 RPM the computer will not
read and the word “STOP” will appear to indicate that the participant is striding faster
than he or she needs to be.
Line 2 Power -
The Power Output is displayed in Watts (currently generating)
and Kilocalories (total value for the workout). The computer toggles back and forth
between Watts (displayed for eight seconds) and Kilocalories (displayed for two
seconds) throughout the ride.
Line 3 Heart Rate -
If there is no Heart Rate signal, a steady heart symbol and
a zero will be displayed. If a participant is wearing a Heart Rate strap, once the
computer locks onto the signal, the heart symbol will blink and display the heart rate.
Please note that the Heart Rate strap must be Polar™ compatible and coded.
Line 4 Elapsed Time -
The number shown reports the total time spent striding
and will reset to zero after 60 seconds of inactivity or if computer is reset using the
gear shifter.
Line 5 Odometer/Trip Distance and Gear -
For the first eight seconds when
the computer is first activated, the Odometer will display the total distance the Strider
has been ridden. This feature is for service and maintenance purposes only. After
eight seconds, the Odometer will display Trip Distance and Gears from 1 - 24.

Average Calculations
To view averages: RPM (Cadence), Power, and Heart Rate at any point in the workout,
stop striding for three seconds. This will flash your averages until you start moving
again or until the computer goes to sleep after 60 seconds.
Resetting Ride Averages, Elapsed Time and Distance
To reset your averages during the workout, stop striding for three seconds and the
averages will start to flash, while they are flashing move the gear shifter from bottom
to top two times quickly. This will reset your workout information back to zero.
Computer Calibration
1. The computer display must be blank. If the display is not
blank wait about 50 seconds until it is blank.
2. Activate the display by rotating the Strider footpad. As soon
as it is active stop the footpad movement.
3. Move the shifter from full retract (lowest resistance) to full
advanced (highest resistance) at least five times. These five
retractions must be done within five seconds.
4. Computer will indicate it is calibrated by showing “55:55”. If
you do not see the “55:55” start over from step # 1.
5. Retract shifter (lowest resistance) and computer should
show gear “1”. Advance shifter (increase resistance) and
computer should show Gears changing “1” through “24”.
6. Continue beyond Gear “24” and “88” will flash. This is the
emergency brake area, where the end of the shifter is about
1” to 1 ¼” off the top of the handlebar. If you do not see the
flashing “88” start over from step # 1.

M5 COMPUTER OVERVIEW
The Keiser M5 Strider is a revolutionary new way to exercise, with a focus on Power
Output. The understanding of the M5 resistance system can best be described in the
explanation of eddy current resistance and the formula for Power:
(Power = Force x Velocity).
Understanding Eddy Current Resistance
An eddy current is an electrical current in a conducting material that results from
induction by a moving or varying magnetic field. On the M5, this is generated by
the wheel passing through two opposing magnets. The flywheel (a conductor)
passes through the magnetic field generated by the two powerful magnets. By varying
how much of the magnetic field comes into contact with the flywheel, the amount of
resistance will increase or decrease for the user. This resistance system also allows
the participant a smoother, quieter, and more predictable workout.
Another major factor that plays a role in resistance is speed. The faster the flywheel
turns, the more energy is generated, and thus the more resistance is created.
Power = Force X Velocity
Power (amount of work being done in a given amount of time by the participant) =
Force (the amount of resistance) x Velocity (the Cadence the user is striding). This is
the same formula that occurs naturally. By moving faster the difficultly increases as
the resistance increases. The same applies to the M5, at a set Gear the resistance can
be increased or decreased by adjusting the participants speed.
In this way the M5 is very similar to natural movement. The higher the Gear, the higher
the Cadence the more Power produced.

If the flywheel is in less contact with the magnetic field, it is easier to operate. The
more of the flywheel that comes in contact with the magnetic field (the higher the
energy that is being generated with each turn) the more difficult it becomes to oper-
ate.
Computer Battery Replacement
To test the computer batteries rotate the crank arm until the computer “wakes up”.
If the battery is low, a “LO-BA” will display in the Odometer (ODO) display at the
bottom of the computer. To replace the batteries unscrew the back of the computer
housing and remove old AA batteries and replace with a set of two new AA
batteries. If you have multiple machines, we suggest all computer batteries be
changed at the same time.
