Retrofitting the C1SR Personality Module
The CENTRON R300 is a one-way radio frequency personality module that transmits
within the unlicensed 910-920 MHz frequency band governed by the US Code of Federal
Regulations (CFR) Title 47, Part 15 Radio Frequency Devices, Sub Part C Paragraph 247
Intentional Radiator. Any device operating within this unlicensed frequency band must
contain an FCC Identification number. Therefore, the FCC ID Label included in the Retrofit
Kits must be placed on the meter as shown below. The retrofit kits for upgrading a meter to
RF capability are only available for energy-only meters.
