The NVM Link
Before calibrating the speaker circuits or when configuring the micro-DAU always remove the NVM link from
pins 1 and 2 on connector P17 and replace the link after speaker circuit calibration and micro-DAU
configuration.
NVM protect - Enabled
P17
After the micro-DAU
is configured, insert the
NVM link across
pins 1-2 of P17 to
preserve the data at
the unit.
NVM protect - Disabled
P17
When the micro-DAU is
being configured, ensure
the NVM link is NOT
fitted across pins 1-2
of P17.
To calibrate the Speaker circuits at the micro-DAU
Ensure the speaker circuits are connected to the terminals on the micro-DAU, the circuits may be calibrated
by pressing the CAL button.
