Displaying the servo error history 1. Enter the test mode. 2. Select the menu group M in the menu screen. 3. Move the cursor to ServoErr and press ENTER key. Note) Servo error data is stored in the SERVO PCBs EEPROM mem- ory. As the power is unstable immediately after being turned ON, data written to the EEPROM at this time will be incorrect. To ensure accuracy, the DA-98HR prohibits data from being written to the EEPROM for 10 seconds after POWER ON. If an error occurs just 10 seconds, the error data is not stored in mem- ory. As a result, the servo error history stored in the memory may differ from actual phenomena. 8 2-8. KEY PCB 1. PLAYSTOPF FWDREW押 電源ON入。 、LED全灯。 2.
