WARNING WARNING
Take proper precautions when making the following system checks.
Hazardous voltages and amperage are present. The front door of the
Smart Trac AC1 must be open and power applied to the unit while
testing. Electrical shock or damage to the equipment may result if
precautions are not taken while testing the power supply. Failure to
comply may result in personal injury or death.
