Adjustment Function
TOP PREVIOUS NEXT
This unit has an error code display function, so that if the unit operates incorrectly, the fault is displayed
using an error code on the FL display of the Tuner/Amplifier (SA-EH570). It also has a servo adjustment
function for displayingthe status of servo system functions (Focus, Tracking, CLV servo) on the FL
display of the Tuner/Amplifier. The system control IC and FL display are part of the Tuner/Amplifier so
make sure the system has been connected properly beforeusing these functions. Use these two functions
for guidance during fault diagnosis and repair.
Note:
Check beforehand for scratching or soiling of the test disc (SZZP1054C), and soiling or other problems
with the pickup lens.
