The region of operation is set using the MercuryAPI. Setting the region of operation
configures the regional default settings including:
Loads the Frequency Hop Table with the appropriate table for the selected region.
Sets the PLL Frequency Setting to the first entry in the hop table, even if the RF is off.
Selects the transmit filter, if applicable.
Frequency Setting
The modules have a PLL synthesizer that sets the modulation frequency to the desired
value. Whenever the frequency is changed, the module must first power off the
modulation, change the frequency, and then turn on the modulation again. Since this can

SRRC, MII The PRC specifications defines more channels
than are in the Nanoʼs default hop table. This is
because the regulations limit channels from 920
to 920.5MHz and from 924.5 to 925.0MHz to
transmit levels of 100mW and below. The
default hop table uses only the center channels
which allow 2W ERP, 1W conducted, power out-
put. If the hop table is modified to use the outer,
lower power channels the RF level will be limited
to the outer channels limit, 100mW (+20dBm)

Full power operation restricts the channel range
from 916.8Mhz to 920.8MHz and all default
channels are within this range.
Per the regulations, this region supports Listen-
before-talk at the required level of -74 dBm.
Open Region No regulatory compliance

This region allows the module to be manually
configured within the full capabilities supported
by the hardware, see

Specifications table. The Open region should
be used for laboratory testing only as it does not
meet any regulatory requirements for any one
region.
