Page 9: Applications Information
Antenna Mounting Positioning and choice of receiver and transmitter antennas are the most important factors in determining system transmission range. The PTM 240C modules are supplied with an- tenna. For standard applications the use of a whip antenna is recommended (L=15cm). -

Page 11: Fcc/Ic Approval Requirements
FCC/IC operational and timing requirements: Because of the very low average to peak factor, the (corrected) field strengths of EnOcean transmitters meet the FCC 15.231 conditions for manually operated transmitters and the lower field strength limit values for intentional radiators operated at a periodic rate. In ad- dition to the field strength limits, the following timing conditions have to be met with re- spect to FCC 15.231:...
