WARNING: This voice terminal is NOT for residential use. It is for business 
systems applications ONLY. Use in a residential environment could result in an 
electrical short circuit when the telephone wiring is set up to provide other 
applications, for example, for appliance control or power transformers. The AC 
power used in these applications may create a safety hazard by placing a direct short 
circuit across the telephone wiring.
