Model(s): CVSO-A, CVSOD-A FCC ID: SK9AMI-1A IC: 864G-AMI1A

General Information:
Applicant: Itron Electricity Metering Inc.
ACS Project: 07-0272
FCC ID: SK9AMI-1A
Device Category: Mobile
Environment: General Population/Uncontrolled Exposure
Exposure Conditions: Greater than 20 centimeters
Simultaneous Tx: No

Technical Information:

Radio 900 MHz LAN 2.4GHz Zigbee
Antenna Type single-band patch half wavelength slot
Antenna Gain 3dBi 1dBi
Conducted Power 21.92dBm 18.71dBm
Maximum EIRP 0.310W 0.094W
Maximum ERP 0.189W 0.057W

Power Density
The Power Density (mW/cm2) is calculated as follows:

PG
S=
4πR 2
Where:
S = power density (in appropriate units, e.g. mW/cm2)
P = power input to the antenna (in appropriate units, e.g., mW)
G = power gain of the antenna in the direction of interest relative to an isotropic radiator
R = distance to the center of radiation of the antenna (appropriate units, e.g., cm)

Installation Guidelines:
The installation manual shall contain text similar to the following advising how to install the equipment to
maintain compliance with the FCC RF exposure requirements:

“RF Exposure (Intentional Radiators Only)
In accordance with FCC requirements of human exposure to radiofrequency fields, the radiating element
shall be installed such that a minimum separation distance of 20cm is maintained from the general
population.”

Conclusion:
This device complies with the MPE requirements by providing adequate separation between the device,
any radiating structure and the general population.
