defective and should be replaced.

7. Full resistance at all levels

a . I ncorrect watt m ultiplier setting - C heck t his s etting in " Set-Up M ode" f unction (SEE " Watt Scalar"
c ategory). If t he s etting is not 1, reset i t t o 1 a nd t est t he m achine by e ntering a w orkout pr ogram. I f
still no resistance, proceed to b.
b . Test f or de fective controller board by di sconnecting the br ake c ables connected to J P1 a nd J P4 on
t he P C boa rd. C rank t he m achine while t he c ables are di sconnected, and not e t he r esistance level. If
machine has a normal level of resistance, the controller board should be replaced.

8. High starting resistance

a . I f a n AC a daptor i s a vailable, connect the m achine to AC pow er. C rank t he m achine and
not e t he r esistance. If t he s tarting resistance is now a t a nor mal l evel, the ba ttery may be ve ry l ow or
de fective. Leave the AC a daptor connected for a t l east 2 hour s, t hen w ith t he a daptor di sconnected,
t est t he s tarting resistance. I f t he s tarting resistance is s till high, c heck the ba ttery voltage by
pl acing the c onsole i n t est m ode. I f t he ba ttery reads l ower t han 1 1.5 vol ts, i t s hould be r eplaced.
Else, proceed to b.
b . Test f or de fective controller board by di sconnecting the br ake c ables connected to J P1 a nd J P4 on
t he P C boa rd. C rank t he m achine while t he c ables are di sconnected, and not e t he r esistance level.
If the machine has a normal level of resistance, the controller board should be replaced.
9. Display shuts off immediately when user stop exercising
a . Th e c o n s o l e fi rmware m ay b e i n " Sh i p p i n g M o d e ". B eg i n a w o r k o u t p r o g r am f o r a s h o r t
period of time, then stop the program. This will disengage the "Shipping Mode". Else, proceed to b.
b. C rank t he m achine to s tart i t, a nd c heck the ba ttery voltage by pl acing the c onsole i n
" Test M ode" s creen, w hile s till cranking. Once i n " Test M ode", c rank t he m achine slower w hile not ing
t he ba ttery voltage. If t he ba ttery reads l ower t han 1 1.5 vol ts, i t s hould b e r eplaced. Else, t he c ontroller
board should be replaced.

10. Fit-Key port does not work

a. Check that the USB drive has the proper "Fitkey.bin" file by plugging it
into a computer and looking at the contents of the USB drive's root
directory. This will also ensure that the drive works properly. If the drive
works, and the file is present, the console should be replaced.
