 Precautions upon Equipment Operation  
 
 
DANGER 
 
Never attempt to check or repair the inside of the equipment. 
Checking or repair by an unqualified person may cause a fire or an electric 
shock. 
Contact our head office, or a nearby branch or local office to request 
servicing. 
 
Never remove the cover of this equipment.   
Touching the high-voltage section inside will cause an electric shock.   
 
Do not attempt to disassemble or tamper with this equipment.   
Otherwise, a fire, an electric shock, or a malfunction may occur.   
 
When conducting maintenance, make sure to turn the main power off. 
Failure may result in electric shock. 
 
Turn off all the main powers before cleaning the equipment. Especially when 
an UPS is used, make sure to turn it off since voltage is still outputted from 
the UPS even after the indicator and the Conning display is turned off. Failure 
may result in equipment failure, or death or serious injury due to electric 
shock.
