• A : B+ Line.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
no mark : DVD STOP
• Voltages are taken with a VOM (Input impedance 10 M

).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.

✩ EEPROM (IC103 and IC706) on the DMB14 board
cannot exchange with single. When EEPROM (IC103
and IC706) on the DMB14 board (A-1199-885-A etc.) is
damaged, exchange the entire mounted board.
