When using the WIFI module of Uascent Technology, a certain tolerance should be reserved for the
output current of the power supply. It is recommended that the output current of the power supply be
≥ 500mA, and a suitable power supply IC packaging should be selected. When supplying LDO power,
attention should be paid to the issue of heating, and when supplying DC-DC power, attention should
be paid to the issue of overshoot at the moment of power on.

similar wording that expresses the same meaning may be used.
2.9
UAM053
Uascent Technology Co.,

www.uascent-iot.com
Testing of the host product with all the transmitters installed - referred to as the composite investigation test-
is recommended, to verify that the host product meets all the applicable FCC rules. The radio spectrum is to
be investigated with all the transmitters in the final host product functioning to determine that no emissions
exceed the highest limit permitted for any one individual transmitter as required by Section 2.947(f). The host
manufacturer is responsible to ensure that when their product operates as intended it does not have any
emissions present that are out of compliance that were not present when the transmitters were tested
individually.
If 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. lt 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).
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.
2.10
Any company of the host device which install this modular should perform the test of radiated & conducted
emission and spurious emission etc. according to FCC Part 15C: 15.247 and15.209 & 15.207, part 15B:
class B requirement, only if the test result comply with FCC part 15C: 15.247, 15B class B requirement. Then
the host can be sold legally.
The host product manufacturer is responsible for compliance to any other FCC rules that apply to the host
not covered by the modular transmitter grant of certification, lf the grantee markets their product as being
Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee
shall provide a notice stating that the final host product still
requires Part 15 Subpart B compliance testing with the modular transmitter installed.
FCC Statement
1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1)This device may not cause harmful interference.
(2)This device must accept any interference received, including interference that may cause undesired
operation.
2. Changes or modifications not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
The device has been evaluated to meet general RF exposure requirement. This equipment should be
installed and operated with a minimum distance of 20 cm between the radiator and your body.
