Matters needing attention:
The 1 antenna side not of metal
2 box can not be large shield
3 should be placed near the electrolytic capacitor in the PAD modules.
The 4 common end of noise inhibition, the need to increase the
operational amplifier in front amplifier or master to eliminate
interference
5 main control, power amplifier, the module must be well grounded,
don't allow the island or closed loop, module grounding
And the main control and power amplifier ground potential difference
between shall not be greater than 1mV.

The output power of this device is less than 20mW.The SAR test is not required.
This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada.
Operation is subject to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1)
l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter
tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en
compromettre le fonctionnement.
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe B est conforme à la norme NMB-003 du Canada.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by
unauthorized modifications or changes to this equipment. Such modifications or changes
could void the user’s authority to operate the equipment.
A certified modular has the option to use a permanently affixed label, or an electronic label.
For a permanently affixed label, the module must be labelled with an FCC ID: KKI-F-3056
The OEM manual must provide clear instructions explaining to the OEM the labelling
requirements, options and OEM user manual instructions that are required
For a host using a this FCC certified modular with a standard fixed label, if (1) the
module’s FCC ID is notvisible when installed in the host, or (2) if the host is marketed so
that end users do not have straightforward commonly used methods for access to remove
the module so that the FCC ID of the module is visible; then an additional permanent label
referring to the enclosed module:
“ Contains Transmitter Module FCC ID: KKI-F-3056” or “Contains FCC ID:
KKI-F-3056” must be used. The host OEM user manual must also contain clear
instructions on how end users can find and/or access the module and the FCC ID.
Host product is required to comply with all applicable FCC equipment authorizations
regulations, requirements and equipment functions not associated with the transmitter
module portion. compliance must be demonstrated to regulations for other transmitter
components within the host product; to requirements for unintentional radiators (Part
15B). To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and fully operational. If
a host was previously authorized as an unintentional radiator under the Declaration of
Conformity procedure without a transmitter certified module and a module is added, the
host manufacturer is responsible for ensuring that the after the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator
requirements. Since this may depend on the details of how the module is integrated with

the host, we suggest the host device to recertify part 15B to ensure complete compliance
with FCC requirement: Part 2 Subpart J Equipment Authorization Procedures ,
KDB784748 D01 v07, and KDB 997198 about importation of radio frequency devices into
