START-UP SERVICE MESSAGES
The following messages are displayed at the beginning of a workout if the associated problem is detected during self-test.
NO STOP - This error generally occurs when the Stop Switch is not connected tightly to the circuit board of the Display
Control Panel. It may also happen if the circuitry associated with the switch develops a fault. When you see NO STOP:
• Set the ON/OFF switch to OFF; wait 2 seconds.
• Set the ON/OFF switch to ON. Notify Star Trac if additional assistance is needed.
KEY DOWN - This error generally occurs when a key is held pressed while the ON/OFF switch is moved to ON. It may also
happen if a key becomes stuck. When you see KEY DOWN:
• Set the ON/OFF switch to OFF; wait 2 seconds.
