NOTE

 

(1)  When power supply switch is ON, replacing lamp is forbidden.   

(2)  After  turning  off  the  power  supply,  wait  until  lamp  cool.  Then 

replace the lamp.   

(3)  When installing new lamp, use clean gloves, cloth and paper to 

hold lamp to avoid any fingerprint left on lamp.   

(4)  After  lamp  has  been  replaced,  when  confirming  the  lamp  ON, 

please  close  the  cover  of  lamp  source  compartment  to  avoid  eye 

iInjury caused by lamp.
