Specific operational use conditions
A typical application scenario for modular transceivers TR-8xGx is wireless
transmission of sensor data or control of actuators and controllers. Modular
transceivers TR-8xGx must not be operated in direct contact with the human
body, on aircraft, and in areas where radio communication is restricted by
local regulations, such as mines. Further, the operation of these transceivers
is subject to ISM band restrictions, which are set by the local
telecommunications authority.
Trace antenna design
In the case of a TR module variant requiring an external antenna, the host
device manufacturer may create a trace antenna on the host PCB (printed
circuit board). This antenna must exactly match the following layout:
The inductance of the SMT coil at the PCB is 8.2 nH. The transceiver
manufacturer assumes no responsibility for any change from these defined
parameters of the trace antenna.
RF exposure considerations
Modular transceivers TR-8xGx are certified as mobile, portable and must be
used as such. The minimum permissible distance from a person’s body is 20 cm.
Due to the low radiation power, if the requirements for the antenna part are
met, no further restrictions are required.
Antennas
For variants of the modular transceiver where an external antenna is used,
professional installation is required. The transceiver manufacturer permits
the use of only the AN-06 external antenna for which compliance with the
parameters required by FCC Part 15.249 can be guaranteed. Refer to
https://www.iqrf.org/an-06. If another type of external antenna is used, a
separate FCC certification is required for the host device.
Label and compliance information
In accordance with KDB Publication 784748, the host device manufacturer is
required to provide the device with a label stating “Contains FCC ID:
R24-TR8xGx”.

Information on test modes and additional testing requirement
Modular transceivers TR-8xGx are delivered with software that guarantees
compliance with FCC requirements. These parameters do not need to be re-
verified during design. When designing the host device, it is only necessary
to use the antenna design specified by the transceiver manufacturer, or the
exact AN-06 antenna type specified by the transceiver manufacturer. See
chapters Trace antenna design and Antennas. For transceiver modules with an
integrated antenna, the antenna design is verified and complies with the FCC.
Additional testing, Part 15 Subpart B disclaimer
The TR-x8Gx modular transceivers are only FCC authorized for the FCC Part
15.249. The host device manufacturer is responsible for compliance with any
other FCC rules.
