Use the Down and Up switches to scroll
through the parameter values. Pressing and
releasing the switches will change the
value by just one incremental value. Press-
ing and holding the switches will scroll at a
faster speed.

When you reach a value that matches the
sticker’s value, stop scrolling and press Set.
The LED Time Code Display will return to
showing time code numbers. Your USD is
now properly calibrated.
The next time you press Set, the LED Time
Code Display will again show O5C CAL. If
you then press the Down switch, you’ll dis-
engage the Oscillator Calibration parame-
ter name. To change the setting once again,
you’ll need to repeat steps 1 through 6.
Restoring Factory Settings
The USD can be reset to its default factory
settings. See “USD Defaults” on page 65 for
default values.
To reset all parameters to default settings:
1
Switch off power to the USD and wait at
least 10 seconds.
2
Hold down the Up and Down front panel
switches and switch on power to the USD—
do not release the Up and Down switches
until the display reads FAC-CFG.

Resetting factory settings does not reset
the USD oscillator. See “Calibrating the USD
Oscillator” on page 64 for information.
