OEM Guidance
1. Applicable FCC rules
This device complies with part 15.247 of the FCC Rules.
2. The specific operational use conditions
This module can be used in IoT devices. The input voltage to the module is
nominally 3.3 V DC. The operational ambient temperature of the module is
-40 °
C ~ 85 °C. the external antenna is allowed, such as dipole antenna.
3. Limited module procedures
N/A
4. Trace antenna design
N/A
5. RF exposure considerations
The equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated wit
h
m
inimum distance 20cm between the radiator and your body. If the equipment
built into a host as a portable usage, the additional RF exposure evaluation may
be required as specified by 2.1093.
6. Antenna
Antenna type: Dipole antenna; Peak antenna gain : 2 dBi
7. Label and compliance information
An exterior label on OEM’s end product can use wording such as the
following: “Contains Transmitter Module FCC ID: 2AOFDFL22-C8”
or “Contains FCC ID: 2AOFDFL22-C8”
8. Information on test modes and additional testing requirements
a) The modular transmitter has been fully tested by the module grantee on the required
number of channels,modulation types, and modes, it should not be necessary for the host
installer to re-test all the available transmitter modes or settings. It is recommended that the
host product manufacturer, installing the modular transmitter,perform some investigative
measurements to confirm that the resulting composite system does not exceed the spurious
emissions limits or band edge limits (e.g., where a different antenna may be causing
additional emissions).
b) The testing should check for emissions that may occur due to the intermixing of emissions
with the other transmitters, digital circuitry, or due to physical properties of the host product
(enclosure). This investigation is especially important when integrating multiple modular
transmitters where the certification is based on testing each of them in a stand-alone
configuration. It is important to note that host product manufacturers should not assume that
because the modular transmitter is certified that they do not have any responsibility for final
product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is
obligated to mitigate the issue. Host products using a modular transmitter are subject to all
the applicable individual technical rules as well as to the general conditions of operation in
Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product
will be obligated to stop operating the device until the interference have been corrected .
9. Additional testing, Part 15 Sub part B disclaimer The final host / module combination
need t
o be evaluated against the FCC Part 15B criteria for unintentional radiators in order
to be properly authorized for operation as a Part 15 digital device.
