4.0 CALIBRATION AND SERVICE
The PicoDAC is designed to make periodic calibration unnecessary. However, the two
internal 9V batteries will periodically need changing. If for any reason the top cover is
removed, the internal DIP switch settings must not be altered. (All switch positions must
be set to OFF.)
If service is needed, please contact Digital Audio Company for assistance.
4.1 Battery Replacement
The normal running time for the PicoDAC on battery power is approximately 6 hours.
To replace the 9V batteries:
1. First disconnect all cables from the unit (including the DC power cable.)
Ensure that the rear power switch is in the OFF position. Loosen (using a
flathead screwdriver) and remove the thumb screws (use a screwdriver if
necessary) on the rear panel.
Be careful not to damage any of the
components in the PicoDAC by static
electricity. Before opening the unit be sure to
touch a grounded metal object.
