intended to alert the user to uninsulated “dangerous voltage” within the device’s enclosure. The international 
symbol of an exclamation point inside a triangle is intended to alert the user to the presence of important 
operating, maintenance and servicing information in the manual accompanying the device.

device. 
14) Damage Requiring Service—The device should be serviced by licensed technicians when: • The plug or 
power supply cord has been damaged. • Objects have fallen or liquid spilled inside of the device. • The 
device has been exposed to moisture. • The device does not appear to be operating properly or exhibits a 
marked change in performance. • The device has been dropped or the cabinet becomes damaged. 
15) Service—The device should always be serviced by licensed technicians. Only replacement parts 
specified by the manufacturer should be used. The use of unauthorized substitutions may result in fire, 
shock, or other hazards.
