WARNING 
  Do not rely exclusively on the nurse call system for alarm notification. Remember 
that the most reliable alarm notification combines audible and visual alarm 
indications with the patient’s clinical condition. 
  Use the specified nurse call cable when connecting with the hospital’s nurse call 
system through the nurse call connection port. Failure to do so may burn the 
machine and produce electric shock hazard.
