No display/partial display/unit will not turn on
BASIC TROUBLESHOOTING
1. Problem:
Solution:
A. Make sure unit is plugged into a functioning wall
outlet.
B. Check power connection at front (recumbent) or rear
(upright) of the unit. Connection should be secure and
undamaged. Replace adapter or connection at unit if
either are damaged.
C. Check data cable integrity. All wires in cable should
be intact. If any are visibly crimped or cut, replace
cable.
D. Check data cable connections/orientation. Insure
cable is connected securely and oriented properly.
Small latch on connector should line up and snap into
place.
E. Check console display for damage. Check for visual
sign that console display is cracked or otherwise
damaged. Replace console if damaged.
F. Check console display. If console only has partial
display and all connections are OK, replace computer.
Advanced Troubleshooting
If above steps do not resolve proceed to advanced
troubleshooting, problem A1.

TROUBLESHOOTING
Unit operates but Contact HR not displayed
BASIC TROUBLESHOOTING
2. Problem:
Solution:
Note: Sensors may have difficulty with dried out or
calloused hands. A conductive electrode cream such as
“Signa Crème” or “Buh-Bump” can help make better
conduct. These are available on the web or at medical
or some larger fitness stores.
A. Ensure hands are centered on HR sensors. Hands
must be kept still with relatively equal pressure applied
to each side.
B. Check HR cable connection at console. Ensure cable
is connected securely to console.
C. Check HR cable box connection. Ensure cables
from handlebars and cable to console are secure and
undamaged. Some models may require seat back be
raised to access cable box.
If the above tests reveal no problems, replace
the handlebars.

Unit operates but Telemetric (if equipped) HR not dis-
played
BASIC TROUBLESHOOTING
3. Problem:
Solution:
A. Verify you are working with a model that features
telemetric HR. Most models do not have this feature.
B. Check chest strap. Strap should be “Polar”
compatible. Make sure strap is directly against skin and
contact area is moist.
C. Check for interference. Try moving unit away from
sources of interference (TV, Microwave, etc.). If
interference is eliminated and HR still does not function,
replace strap and console.
Console displays “E2” error code
4. Problem:
Solution:
A. Check data cable integrity. All wires in cable should
be intact. If any are crimped or cut, replace cable.
B. Check data cable connections/orientation. Insure
cable is connected securely and oriented properly.
Small latch on connector should line up and snap into
place.
If the above tests reveal no problems, replace
the DC Motor.

TROUBLESHOOTING
No speed/RPM reading
BASIC TROUBLESHOOTING
5. Problem:
Solution:
A. Check data cable integrity. All wires in cable should
be intact. If any are crimped or cut, replace cable.
B. Check data cable connections/orientation. Ensure
cable is connected securely and oriented properly.
Small latch on connector should line up and snap into
place.
C. Check magnet position (requires shroud removal).
Magnet should be in place on flywheel. If no magnet
present, replace flywheel or entire base unit if customer
unable to replace flywheel.
D. Check RPM Sensor (requires shroud removal). RPM
sensor should be aligned with magnet and connected
to data cable. Re-align sensor if necessary; replace if
any damage to sensor or connecting wire.

Console shuts off (enters sleep mode) while in use
BASIC TROUBLESHOOTING
6. Problem:
Solution:
A. Check data cable integrity. All wires in cable should
be intact. If any are crimped or cut, replace cable.
B. Check data cable connections/orientation. Insure
cable is connected securely and oriented properly.
Small latch on connector should line up and snap into
place.
C. Reset Machine (if equipped with reset button).
Unplug unit from electrical outlet for 3 minutes.
Reconnect to outlet and after console powers up press
“reset”.
D. Check magnet position (requires shroud removal).
Magnet should be in place on flywheel. If no magnet
present, replace flywheel or entire base unit.
E. Check RPM Sensor (requires shroud removal). RPM
sensor should be aligned with magnet and connected
to data cable. Re-align sensor if necessary, replace if
any damage to sensor or connecting wire.

TROUBLESHOOTING
Unit rocks/does not sit level
BASIC TROUBLESHOOTING
7. Problem:
Solution:
A. Check leveler adjustment. Leveling feet may be
turned in or out to level bike.
B. Check surface under unit. Adjustment may not be
able to compensate for extremely uneven surfaces.
Move bike to level area.
Pedals loose/unit difficult to pedal
8. Problem:
Solution:
A. Check pedal to crank connection. Pedal should be
tightened securely to crank. Insure connection is not
cross-threaded.
B. Check crank to axle connection. Crank should
be tightened securely to axle. Be sure cranks are
connected at 180 degrees from each other.
Seat post feels loose
9. Problem:
Solution:
A. Insure adjustment pin is locked into one of the seat
post adjustment holes.
B. Insure knob is securely tightened.

ADVANCED TROUBLESHOOTING
No display/Unit will not turn on
A1. Problem:
Solution:
A. Check A/C adapter. Using a volt meter check the
voltage output from the adapter. With positive lead
on inside of connector and negative lead on outside,
voltage should be within 9-14VDC. If voltage is outside
this range, replace adapter. If voltage is OK, check
computer.
B. Disconnect upper wiring harness from back of
computer, and while power is supplied to machine, use
a volt meter to check that voltage is reaching computer.
Voltage between pins 1 (purple) and 3 (pink), (Figure A),
should be within 9-14VDC. If voltage is within range,
replace computer. If not, check upper wiring harness.
C. Remove console mast and disconnect upper wiring
harness from lower wiring harness. Test output voltage
at lower harness using pins 1 and 3, as above. If
voltage is now present between 9-14VDC, replace
upper wiring harness. If not, check power plug wire.
D. Remove the shroud half that has the power plug
mounted into it. Disconnect power plug wire from
resistance motor wiring harness. Test voltage output of
power plug wire. If no voltage present, replace power
plug wire. If voltage is within 9-14VDC, replace DC
MOTOR (includes lower wiring).

ADVANCED TROUBLESHOOTING
Resistance does not change (assumes unit powers up
and otherwise functions normally)
A2. Problem:
Solution:
A. Check computer wire connections and continuity.
Replace any damaged wires. If wire is OK, check servo
motor.
B. Check servo motor. Remove shrouds. Test voltage
at servo motor red and black wires, (Figure B). Voltage
should be approximately 2.5VDC while either the UP
or DOWN console resistance buttons are pressed. If
voltage is correct but motor does not turn, replace
DC MOTOR (includes lower wiring). If motor turns
but magnet arm assembly does not move, check and
secure the mechanical components. Replace any
damaged components.
