Troubleshooting: Visual Inspection
A thorough visual inspection of the equipment can save time. Small
things—disconnected cables, foreign debris on circuit boards, missing
hardware, loose component—can frequently cause symptoms and
equipment failures that may appear to be unrelated and difficult to
track.
Take the time to make all of the recommended visual checks (refer to the
visual inspection chart on the next page) before starting any detailed
troubleshooting procedures.
CAUTION
Before performing any maintenance or repair on the
equipment, take precautions against electrostatic
discharge damage. See "Controlling Electrostatic
Discharge" in Chapter 3.
CAUTION
Solder multilayer and surface mount PCB assemblies at
your own risk! Improper repair methods can damage the
PCB assemblies even further. Only qualified service
personnel with the proper equipment should attempt to
repair PCBs.
Set the treadmill's power switch to off (0). Disconnect the power cord
