1. Error Signal Check Steps And Sol tions
1.1. 【LS】：Can not receive signal from speed sensor over 8 seconds while workout, all
windows display will off, all output will stop, and show 【LS】 on TIME window.
※If this is a all new product that just finished assemble, there are more possibly in
assemble problems, maybe connect wire not well or wire damaged while assemble.

If calibrate normally and return to idle
mode, please check the SPEED para
meter on
CALORIES window when calibrate speed at
max speed 2 km/h(± .1).
In normal condition, the SPEED parameter
shall be between 34 ~35 .
If calibrate abnormal, open motor cover
and check speed sensor connected well.
If speed sensor connected well, please
replace the sensor and check again.
Refer to 2.3『Speed Sensor』
I
f still show error signal, have to check
the console wire, damage or connect

13 If all function are normal and no error
signal after reset power, it maybe cause
by power core, maybe power core connect not
well, please check the power core.
If all function are normal and no error
signal after reset power, maybe the
loading is too heavy and inverter to start
the over current protect mode. I
f loading
is too heavy the motor noise will more
louder over 12km/h and running belt speed
will decreased or slippery while loading
.
P
lease maintenance or replace the running
belt and running deck.

On the AC power and check the fan where on
the inverter operate normal, otherwise the
inverter will over heating and to start
