match that of the board that has not been replaced. Event codes 78 and 79 are used to display warnings to
the user screen concerning belt replacement.

Event 71:

This event is used to report that a virgin lower board has been installed and that the upper board's odometer
information should be written to the virgin lower board. The write operation occurs at the start of a workout.
Event 72 & 73:
This event is used to report that an odometer write operation had failed. The unit responds by re-writing the
odometer record.
Events 74 – 77:
These events are used to report that an upper or a lower board has been replaced. Through the use of
complex software algorithms the system determines which board is the replacement and makes the
odometer reading of the replacement board match that of the board that has not been replaced. The write
operation for these events will occur during the workout summary, and the workout summary will always
occur 20 seconds after the pedals stop moving.
WARNING: If you are troubleshooting by swapping boards, you must remember to unplug the data cable
from one board within that 20 second window before the workout summary, or the odometer will be
overwritten. This could potentially cause all the units at the club to have incorrect odometer information, and
all accurate belt replacement tracking would be lost.
Event 78:
This event is used to report that the odometer has reached 90 million strides since the last belt replacement.
The system will display "Replace Belts Soon" at the banner screen.
Event 79:
This event is used to report that the odometer has reached 100 million strides since the last belt
replacement. The system will display "Replace Belts now" at the banner screen and lock out all user controls.

Troubleshooting Heart Rate Issues:

Hand Held Heart Rate Does Not Work

1. Place your hands on the HHHR (Hand Held Heart Rate) contacts, making full contact with both
top and bottom contacts for at least 15 seconds.
If the unit displays a heart rate, no problem exists.
If the unit does not display a heart rate value within this time, continue to step 2.
2. Set the on/off switch to the off position, wait 10 seconds, then set the on/off switch to the on
position and repeat step 1.
a. If the HHHR functions correctly, then the processor on the HR board was in a "latched-up"
condition, and cycling the power cleared the condition.
