INTEGRATION INSTRUCTIONS
1. This module has been tested and found to comply with the FCC Part15.247 for
Modular Approval.
2. This Modular Approval is limited to OEM installation for mobile and fixed applications
only. The antenna installation and operating configurations of this transmitter, including
any applicable source-based time- averaging duty factor, antenna gain and cable loss
must satisfy MPE categorical Exclusion Requirements of 2.1091. This modular should
be installed and operated with minimum distance 20 cm between the radiator& your
body.
3. The U.FL connector antenna has been approved for the modular. For situations
where the host manufacturer is responsible for an external connector, the integration
instructions shall inform the installer that a unique antenna connector must be used on
the Part 15 authorized transmitters used in the host product.
4. When the module is installed in the host device, the FCC ID label must be visible
through a window on the final device or it must be visible when an access panel, door or
cover is easily removed. If not, a second label must be placed on the outside of the final
device that contains the following text: ―Contains FCC ID: 2AF6B-RAK2243.
5. The Shenzhen Rakwireless Technology Co., Ltd. uses various test mode programs
for test set up which operate separate from production firmware. Host integrators should
contact Shenzhen Rakwireless Technology Co., Ltd. for assistance with test modes
needed for module/host compliance test requirements.
6. Summarize the specific operational use conditions
This module can be used in household electrical applicances as well as lighting
equipments.The input voltage to the module should be nominally 4.5 to 5.5VDC,typical
vale 5.0VDC and the ambient temperature of the module should not exceed 85°C.This
module using only one kind of antennas with maximum gain is 3.0dBi.Other antenna
arrangement is not covered by this certification.
The antenna is not field replaceable.If the antenna needs to be changed,the certification
should be re-applied.
7. 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 transmitter,digital circuitry,or due to physical properties of the
host product(enclosure).This investigation is especially important when integrating
