2. Perform this adjustment in an ambient temperature of 22 

°

C to

28 

°

C.  Perform it immediately after the power is turned on

when the internal temperature of the unit is the same as the
ambient temperature of 22 

°

C to 28 

°

C.

3. When D101 has been replaced, perform this adjustment after

the temperature of this part has become the ambient tempera-
ture.

Adjusting Method:
1. Press the  

= 0 button or ) + button and display
