The following settings govern the operation of the MNU IS in QuickMode:
• QuickMode (Holding Register 40421) sets the number of samples to be averaged.
• QuickMode Delay (Holding Register 40422) determines the length of delay after sensor power up
before the first sample is taken.
• When a non-zero number is written to QuickMode Resample Instruction (Holding Register 40187), a
sensor in waiting status initiates QuickMode operation.
For multiple sensors on the same network, or redundant sensors in close proximity with one another,
use QuickMode Delay (Holding Register 40422) to sequence each sensor’s sampling to prevent unwanted
acoustical crosstalk.

NOTE : Cycling the power of your MNU IS will not affect its QuickMode settings. Only
changing Holding Register 40421 to or from 0 will initiate or exit QuickMode.
