What to do if Usl Recording Equipment sound system does not work and no LEDs are lit on the Front Panel?
If the Usl Recording Equipment sound system does not work and no LEDs are lit on the front panel, reset the circuit breaker or replace the fuse. Ensure the power cord is firmly seated. Replace the fuse with a SLO BLO 500 mA, 250 V fuse.
What to do if no sound in one or more front channels of Usl Recording Equipment?
If there's no sound in one or more front channels of your Usl Recording Equipment, and the channel or channels are still dead, the issue likely lies with an amplifier, speaker, or wiring. If all front channels work, the problem is in the JSD unit. Check different formats to see if the problem is isolated to one format. Refer to later section in TROUBLESHOOTING.
What to do if all the format button LEDs flash and numbers appear in the main fader display of Usl Recording Equipment?
If all the format button LEDs flash and numbers appear in the main fader display on your Usl Recording Equipment, make a note of the numbers displayed. Put the unit into BYPASS to prevent possible loudspeaker damage. The flashing LEDs indicate detected software corruption. A “91,” “92,” or “93” signifies a software fault in the Input Module (JSDA80), while a “61,” “62,” or “63” indicates a software fault in the Output Module (JSDO80). Have a technician replace the defective module and follow the System Restore procedure in Section 10.4.
