10M/MX Calibration
The Pure2 can be calibrated periodically in order to calibrate the accuracy of the internal
clock by connecting it to the Antelope Audio 10M/MX Atomic Clock. This is not something
that necessarily needs to be done very often, but if desired, please follow these
instructions:
• Connect a 10M/MX unit to Pure2 via the dedicated 10M input.
• Power on the 10M and wait until it reaches operating temperature.
• With the Pure2 powered up, press and hold the Power button.
• Turn the Rotary control to navigate to the ‘10M Calibration’ option.
• Confirm the selection by pressing the Rotary control.
• The Calibration screen appears showing the Oven Temperature and AC Lock
status.
• Wait for the sign Locked. Error value will now be displayed at the bottom of the
screen.
• Wait for the calibration to take place.
• When the Err. Number becomes stable, press the Rotary control (7) again to end
the calibration.
• You will see “DONE” displayed on the LCD screen. You may exit the menu pressing
the Volume Select button.
