In early FL8300 production units, the Digital Output level was 240 mV ±10% peak to peak. Based on our research, we found that some D/A converters require more than 240 mV for intermittent free operation. In the event you receive a FL8300 from a consumer with the a complaint "Intermittent Sound from External D/A converter", check the serial number in the table below. If the FL8300 has a serial number higher than indicated in the table below, connect a properly working D/A converter to the Digital Output and verify interruption free operation. Also confirm the Digital Output level of the FL8300 is 500 mV ±10% Peak to Peak. If the FL8300 passes these two tests, advise the customer to have their external D/A converter and connecting cables checked. If the FL8300 has a serial number lower than indicated in the table below, perform the following modification: 1) With the unit plugged in and turned on, push the "open/close" button to extend the drawer fully; then turn the unit off and unplug it. 2) Open the top cover (6 screws). 3) Remove output board PCB3 from the rear panel (4 screws). This board can be pulled back and modified without completely removing it from the chassis. 4) Locate resistor R901, it may be a 680 ohm resistor or a jumper wire; replace in eith
