Before you begin, please note:

Calibration is only required under one (or both) of the following conditions:
1. The computer has been replaced;
2. The magnet assembly has been disassembled for any reason.
This calibration procedure applies to computer software version U406 and above. This includes production models build after mid-September, 2009. Learn how to check your software version, and your manufacture date.
To check your software version, remove the batteries for 20 seconds, then reinstall the batteries. Observe the computer display during start-up and look for “U###”.
To find your manufacture date, check the date code in your product's serial number.
This process requires a special tool, supplied by Keiser (Red Calibration Tool, PN 555089).
The following steps must be completed within 30 seconds. After 30 seconds, the computer will exit calibration mode and must be allowed to sleep before attempting calibration again.

STEP 3 through STEP 6 must be completed within 30 seconds.

Begin with the Computer off. Then, push the Resistance Lever to the lowest position.
Pedal 1 full revolution. The following “Time Row” value will be displayed:
- M5i = “1”
- M5 = “0:00”
Position the Calibration Tool (Cal Tool):
- Place the Cal Tool onto the Flywheel as shown above.
- Slide the Cal Tool up until the Cal Tool comes to a hard stop beneath the magnet holder.
Engage the Magnets into the Cal Tool:
- Turn the Magnet Cover counter-clocwise until the Magnets stop against the cutouts in the Cal Tool.
- Release the Magnet Cover and allow it to return to its rest position.

Move the Resistance Lever from stop to stop 6 times.

Make sure the Resistance Lever makes the complete travel from stop to stop all six times. Failure to do so may force an error.
