3. Safety Precautions 
Please observe the following precautions to ensure patient and operator safety when using 
this system.   
DANGER:  Do not use flammable gasses such as anesthetic gas, oxygen or 
hydrogen, or flammable liquids such as ethanol, near the system, 
because there is danger of explosion.   
WARNING: 
 1. Do connect the plugs of the system and peripherals connected to 
the system to the wall receptacle meeting the ratings indicated on 
the rating nameplate. Using adapter or multi-functional receptacle 
may affect the system’s grounding performance and thus cause 
leakage current exceeding safety requirement.   
 
Be sure to connect the video printer to the designated AC outlet on 
the system with the provided cable. Using other cables may cause 
electric shock. 
 2. Be sure to connect the potential-equalization lead wire before 
inserting the system power plug into the receptacle and be sure to 
remove the system power plug from the receptacle before 
disconnecting the wire, in order to avoid electric shock. 
 3. Connect the earth conductor only before turning ON the system.   
Disconnect the grounding cable only after turning OFF the system.   
Otherwise, electric shock may result. 
 4. For the connection of power and grounding, follow the appropriate 
procedures described in the operation manual. Otherwise, there is 
risk of electric shock. Do not connect the grounding cable to a gas 
pipe or water pipe, otherwise functional grounding may not be 
effective or there may be risk of a gas explosion. 
 5. Before cleaning the system, be sure to disconnect the power cable 
to avoid electric shock.
