Note: The OEM is free to choose another vendor’s antenna of like type and equal or lesser gain as an
antenna appearing in the table and still maintain compliance. Reference FCC Part 15.204(c)(4) for
further information on this topic. To reduce potential radio interference to other users, the
antenna type and gain should be chosen so that the equivalent isotropic radiated power (EIRP) is
not more than that permitted for successful communication.

Power Exposure Information
In general, there are two agency classifications for RF radiation exposure in wireless applications: mobile and
portable.
Mobile – A mobile device is a transmitting device designed in such a way that a separation distance of at least
20 cm is normally maintained between the transmitter's radiating structures and the body of the user or
nearby persons. The BT740 is fully modular approved for mobile and fixed applications (reference FCC Part
2.1091 for further details on mobile devices)
.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Portable – Portable is a classification of equipment where the user, in general, is within 20 cm of the
transmitting antenna. Portable equipment is further broken down into two classes: within 2.5 cm of human
contact and beyond 2.5 cm. The BT740 does not hold a portable approval classification due to its peak
output power and modular approval restrictions. Customers who want to use the BT740 in portable
applications require further RF evaluation. Contact a qualified test house or a Laird representative for further
information on this topic (reference FCC Part 2.1093 for further details on portable devices).
Maximum Permissible Exposure report was created and shows the minimum distances for Public and
Occupational use of the BT740.
