Carefully follow these safety requirements before servicing the USB 
DynaKey. 
Warning: 
The DynaKey LCD contains hazardous voltages and 
should only be serviced by qualified service personnel. 
Warning: 
Before servicing the equipment plug your safety strap 
into a proper grounding outlet. Failure to do so could damage the 
equipment. 
Caution: 
Before servicing the USB DynaKey, power down the 
terminal or PC and disconnect the terminal AC power cord. Disconnect 
the cables from the workstation. 
Caution: 
To protect the internal circuitry from damage, unplug the 
AC power cord and then momentarily press the power switch ON to 
drain the power supply capacitance.

The power supply cord is used as the main disconnect 
device. Ensure that the socket outlet is located/installed near the 
equipment and is easily accessible.
