Hi, Tom. Sorry I left out that key detail. This is inductive coupled communication (and charging).
Charlie Blackman sent me a lead on RTTE guidance from CEPT. I am fairly certain this device can be considered Class 1, sub-class 74 under RTTE. The mag field for the communications is quite small. The field for charging is higher, but I assume it can be ignored (inductive charging is not covered by RTTE).

Hi Lauren Is this over the air 1700 kHz transmission or conducted over wire or AC mains? best regards Tom Cokenias On Apr 10, 2013, at 4:00 PM, Crane, Lauren wrote: I am looking for advice on how to determine the EU RTTE class of a product. The product has a base station and a sensor. The battery powered sensor can be taken out of the base station and used elsewhere to do its sensing thing, and then be brought back to the base station for charging and uploading of the sensed data. The nominal transmit frequency for sense data communication is 1700 KHz +/-100 KHz. The modulation scheme uses On-Off Keying (OOK). The nominal baudrate base station to sensor is 1,000 Hz. The nominal baudrate sensor to base station is 8,000 Hz. Based on this information, can someone help me understand which RTTE class this product is, and why?
