9 CE REGULATORY
The RM186 has been tested for compliance with relevant standards for the EU market. The RM186 module has been tested
with a 2.0dBi external dipole antenna for LoRa, and the -1.5dBi on-board chip antenna for the BLE transmitter. For the
external LoRa dipole antenna, the OEM can operate any other type of antenna but must ensure that the gain does not
exceed 2.0dBi to maintain the Laird Technologies approval.
The OEM should consult with a qualified test house before entering their device into an EU member country to make sure
all regulatory requirements have been met for their complete device.
Reference the Declaration of Conformities listed below for a full list of the standards that the modules were tested to. Test
reports are available upon request.
9.1 Antenna Information
The external flying lead U.FL dipole antennas for the 868MHz LoRa radio listed below were tested for use with the RM186.
For CE mark countries, the OEM is free to use any manufacturer’s antenna and type of antenna as long as the gain is less
than or equal to the highest gain approved for use (2.0dBi) Contact a Laird Technologies representative for more
information regarding adding antennas.

Note: The RM186 module internal BLE chipset IC pins are rated 4 kV (ESD HBM). ESD can find its way through the
external 2-Wire SWD Programming/Debug Interface connector (if used on the customers design), if discharge is
applied directly. Customer should ensure adequate protection against ESD on their end product design (using the
RM186 module) to meet relevant ESD standard (for CE, this is EN301-489).
