2.5 : Antenna design

When the customer selects the internal on-board antenna, antenna design should comply with the following rules
and modules of the proposed location:
②

：The antenna must be away from the metal or high component of at least 10 mm

②：The antenna can not be any piece of enclosure protection All shells, including

plastics, should be kept away from the antenna area at least 10 mm

2.6 : PCB design description

The power to recommend the use of LDO for DC 3.3V , provide the driving current of at least
30mA, the module of power capacitor placed a 10uF proposalIn the PCB layout, the BLE module is placed should
be kept away from the magnetic field source such as transformers and coils

2.7 : Rest

When the module network, to back network, no mobile phone APP on the network when the network back, the
need for a hardware reset reset method: power up and down in the form of (three short and two long), first power
on 1-3S, and then, repeat 3 times, then 2 long time the 5-10S on the

electrical operation can be reset。

ORIGINAL EQUIPMENT MANUFACTURER (OEM) NOTES

The OEM must certify the final end product to comply with unintentional radiators (FCC Sections 15.107 and 15.109)

before declaring compliance of the final product to Part 15 of the FCC rules and regulations. Integration into devices

that are directly or indirectly connected to AC lines must add with Class II Permissive Change.

The OEM must comply with the FCC labeling requirements. If the module’s label is not visible when installed, then an

additional permanent label must be applied on the outside of the finished product which states: “Contains transmitter

module FCC ID: 2AOC5LCBTMD02”. Additionally, the following statement should be included on the label and in

the final product’s user manual: “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 interferences, and (2) this device must accept any

interference received, including interference that may cause undesired operation.”

The module is limited to installation in mobile or fixed applications. Separate approval is required for all other operating

configurations, including portable configuration with respect to Part 2.1093 and different antenna configurations.

A module or modules can only be used without additional authorizations if they have been tested and granted under

the same intended end‐use operational conditions, including simultaneous transmission operations. When they have

not been tested and granted in this manner, additional testing and/or FCC application filing may be required. The most

straightforward approach to address additional testing conditions is to have the grantee responsible for the certification

of at least one of the modules submit a permissive change application. When having a module grantee file a

permissive change is not practical or feasible, the following guidance provides some additional options for host

manufacturers. Integrations using modules where additional testing and/or FCC application filing(s) may be required

are: (A) a module used in devices requiring additional RF exposure compliance information (e.g., MPE evaluation or

SAR testing); (B) limited and/or split modules not meeting all of the module requirements; and (C) simultaneous

transmissions for independent collocated transmitters not previously granted together.

This Module is full modular approval, it is limited to OEM installation ONLY.

Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change.

(OEM) Integrator has to assure compliance of the entire end product include the integrated Module.

measurements (15B) and/or equipment authorizations (e.g Verification) may need to be addressed depending on

co-location or simultaneous transmission issues if applicable.

Additional

(OEM) Integrator is reminded to assure that these installation instructions will not be made available to the end user of

the final host device.
