5. Press ENTER to scan LEDs to verify display functionality
6. After pressing ENTER the TIME window shows “test” and the keypad functionality can be tested (the value displayed changes when a button is being pressed)
7. Press ENTER to enter IO mode (TIME display shows lift motor potentiometer value, SPEED reads speed from speed sensor and DISTANCE shows heart rate pulse)
Press START to test lower board relay (a click sound) and then press ELEVATION UP for 2 seconds to increase the elevation to 8%. Press ELEVATION DOWN to decrease the elevation to minimum percentage 0%
Press SPEED UP to increase speed value and ‘SPEED DOWN’ to decrease speed value.

Lift motor calibration
The lift motor calibration is done manually by following the following steps:
1. Drive the lift motor to 0% from user interface (inclination display must be 0%)
2. Switch off the treadmill and unplug the power cable
3. Remove motor cover
4. Fold up the running deck
5. Loosen two screws (A) attaching the lift motor nut (B) to the incline frame
6. Adjust the lift motor nut (B) so that there is 9 mm gap between the upper end of the nut and the lift motor frame

ERROR CODES
E1
The error will appear if the upper board cannot
receive pulses from the speed sensor for 10 seconds.
Possible reasons:
Speed sensor not properly assembled, the distance between the magnet and the speed sensor should be less than 3mm.
Speed sensor cable disconnected
Meter cable has a poor connection at some point
Magnet missing from the front roller pulley
Front roller not rotating at all due to loose drive belt
Check the distance between the speed sensor and the flywheel and ensure that the speed sensor is properly attached to the motor frame. Check also speed sensor connections.
Error can be reset also by re-inserting the safety key.

E6
The error message appears when voltage is being
supplied to the lift motor but it doesn’t move.
Possible reasons:
Lift motor power cable disconnected
Lift motor electronically damaged preventing the movement
Error can be reset only by disconnecting the power cable.
Lift motor power cable disconnected
Lift motor electronically damaged preventing the movement
Error can be reset only by disconnecting the power cable.
E7
The values the lift motor potentiometer is
sending are not within the preset limits.
If the readout from the potentiometer is 1 the
software is not picking any signal from the potentiometer
Possible reasons:
Lift motor rotation sensor (potentiometer) cable disconnected
Lift motor rotation sensor has poor internal contact thus providing incorrect values
The second connection cable between user interface and lower board disconnected
The potentiometer has lost its calibration and rotated to minimum
Possible reasons:
Lift motor rotation sensor (potentiometer) cable disconnected
Lift motor rotation sensor has poor internal contact thus providing incorrect values
The second connection cable between user interface and lower board disconnected
The potentiometer has lost its calibration and rotated to minimum
If the readout from the potentiometer has lost
its calibration setting and it differs from reference values adjust potentiometer
to obtain correct value.
If the potentiometer has lost its position it
can be lifted up after removing two attachment screws. Turn the potentiometer
shaft to obtain correct setting and place the potentiometer back to the lift
motor. To ensure that potentiometer maintains correct calibration setting a
small amount of glue should be added to shaft before inserting it back to its
counterpart.
Error can be reset also by re-inserting the
safety key.
TROUBLESHOOTING
Treadmill is making knocking noise
The best way to start finding the root cause of the problem is to listen to the frequence of the noise. For example, the running belt seam overlaps a roller twice per revolution, should this be the frequency of the noise, the belt needs to be adjusted or replaced. If the noise has significantly higher frequency it is likely to be caused by a damaged front or rear roller bearing.
Adjust the rear foot to make the treadmill deck even with the floor

Heart rate readings are inaccurate
The motor wires needs to be wrapped through a ferrite ring and twisted around each other in order to prevent possible heart rate reading interference.
Home appliances, e.g. TV and mobile phone, and electric network can generate interference. Try using equipment in different environment.

Circuit breaker (10A) trips repeatedly
Check that the treadmill is running mechanically free
Check belt lubrication
If the wall outlet voltage is lower than normal the required current is higher and might cause the breaker to trip
