Emergency Stop Switch Verification

Verify that the emergency stop switch is installed and connected. The emergency stop
switch (ESTOP) must be installed for the T2100 Treadmill to operate. If the ESTOP is not
installed, the T2100 Treadmill will not operate.

ON/OFF Switch

When turning the T2100 Treadmill ON/OFF switch to the OFF position, there is a period
of approximately 1 second when the remaining power cycles through the system. The
T2100 Treadmill will not power up until all remaining power has cycled through the
system. After turning OFF the T2100 Treadmill, wait approximately 1 second before
turning the ON/OFF switch back ON.

Burn-In Mode

Burn-in mode is a repetitive cycle of elevation calibration and walking belt
revolutions. It can be helpful when attempting to replicate an intermittent problem
for troubleshooting.
