Trouble Shooting
All Embedded Display Products perform a self-test at the beginning of every workout. If a problem is detected, a mes-
sage displays before or after the workout, depending on the nature of the problem. Star Trac recommends that you refer
your questions about your STAR TRAC PRODUCTS operation and suspected malfunctions to Star Trac’s Service Hot-
line at (800) 503-1221, or USA 1-714-669-1660.
The following messages are displayed at the beginning of a workout if the associated problem is detected during self-test
(codes used in the FIT_ERROR and DISP_ERROR commands). For Treadmills xCB is the Translator Board and For
Bikes, TBTs and Steppers it is the LCB Board.
