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 monopole antenna.
3. Limited module procedures

4. Trace antenna design

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.8. 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. 9.Additional testing, Part 15 Sub part B disclaimer The final host / module
combinationneed to be evaluated against the FCC Part 15B criteria for unintentional
radiators in orderto be properly authorized for operation as a Part 15 digital device.
10. The host integrator installing this module into their product must ensure that the final
composite product complies with the FCC requirements by a technical assessment or
evaluation to the FCC rules, including the transmitter operation and should refer to guidance
in KDB 996369. For host products with certified modular transmitter, the frequency range of
investigation of the composite system is specified by rule in Sections 15.33(a)(1) through (a)
(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1), whichever
is the higher frequency range of investigation When testing the host product, all the
transmitters must be operating. The transmitters can be enabled by using publicly-available
drivers and turned on, so the transmitters are active. In certain conditions it might be
appropriate to use a technology-specific call box (test set) where accessory 50 devices or
drivers are not available. When testing for emissions from the unintentional radiator, the
transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only
is not possible then, the radio shall be passive (preferred) and/or active scanning. In these
cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB)
to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to add
attenuation or filters depending on the signal strength of any active beacons (if applicable)
from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further
general testing details. The product under test is set into a link/association with a partnering
device, as per the normal intended use of the product. To ease testing, the product under
test is set to transmit at a high duty cycle, such as by sending a file or streaming some media
content.
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 with minimum 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: Monopole antenna; Peak antenna gain: 2.44 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: 2A4G5-HLM9933”
or “Contains FCC ID: 2A4G5-HLM9933”
8. Information on test modes and additional testing requirements
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).
