6-4-3  Initialization of FVR value 

 

Press and hold the thin body key (one of the body thickness 
correction keys) until “cancel” is displayed (for approximately 
3 seconds).

  

 

 

NOTE

   

The FVR value can be initialized in initialization of 
the NEXSC PCB.  In this case, however, other 
data (such as APR) is initialized at the same time.

6-5  Replacement of Collimator Lamp

・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・

 

Replace the collimator lamp using the following procedure.

 

 

 

CAUTION

 

  Never touch directly the collimator lamp.    If dirt is adhered on the lamp, the illuminance may 

be deteriorated. 

 

 

NOTE

 

 

After the power of the system has been OFF for a while or after a while after the key switch was 
set to OFF (that is, after the collimator lamp is cooled down), replace the collimator lamp. 

 

1.    Remove the lamp outer cover of the collimator.

 

2.    Remove the lamp cover.

 

3.  Replace the lamp 

(P/N 062-65003-02 halogen lamp)

.
