2.4 Compliance Limits

The register value used for FCC compliance is maximum value and cannot be increased by
end user. The RF Output Power configuration is not accessible to End User.

2.5 Module Features and Operation

The rebel UI module intended to operate with pre-certified power supply of typical voltage

12.7VDC ranging from 11V-13.5V.
The Module has the high bandwidth Wi-Fi module (WCN3990) for data and video transfer over

Wi-Fi interface. Which also supports the communication over Bluetooth.
It supports Wi-Fi (802.11 a/b/g/n/ac - 2x2 MIMO, ISM 2.4GHz at 20MHz/40MHz and 5GHz at

20/40/80 MHz) and Bluetooth (BT5.0).
The USB Type-C Port supports a USB based camera for the appliance cavity. On board

speaker connector supports a 1W speaker. There’s a connector at the top edge of the PCB
where LCD and capacitive touch panel gets connected with the rebel UI Module.

It also has the support of ALS and Proximity sensor and the 8MP camera. To support these
features an additional board named camera sensor board will be attached through a FPC/FFC
Cable. The DMICs placed onto the Sensor Board Supports the voice capturing and voice
recognition functionalities.

3 FCC Compliance Notices

FCC ID: A5UEICHRB01

This rebel module complies with Part 15 of the FCC Rules. The 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.

Under FCC regulations, this radio transmitter may only operate using an antenna of a type
and maximum (or lesser) gain approved for the transmitter by FCC. To reduce potential radio
interference to other users, the antenna type and its gain should be so chosen that the
equivalent isotopically radiated power (e.i.r.p.) is not more than that necessary for successful
communication. The radio transmitter FCC: A5UEICHRB01 has been approved by FCC to
operate with the antenna types listed below with the maximum permissible gain and required
antenna impedance for each antenna type indicated. Antenna types not included in this list,
having a gain greater than the maximum gain indicated for that type, are strictly prohibited for
use with these devices.

One of the below two Antenna configuration will be used:

FCC Caution!!!

 Changes or modifications not expressly approved by Whirlpool Corporation could void

the user’s authority to operate the equipment.

Whirlpool Corporation  2000 M-63  Benton Harbor, MI 49022

Rev 1.0 Page 12

 The antenna(s) used for this transmitter must be installed such that a minimum

separation distance of 20 cm is maintained between the radiator (antenna) and all
persons at all times and must not be co-located or operating in conjunction with any
other antenna or transmitter.”

Part 15B compliance statements for digital devices:
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 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 user manual for the end product must include the following information in a
prominent location Instruction:

“To comply with FCC RF radiation exposure limits for general population, the antenna(s) used

for this transmitter
Must be installed such that a minimum separation distance of 20 cm is maintained between
the radiator (antenna) and all persons at all times and must not be co-located or operating in
conjunction with any other antenna or transmitter.”

3.1 OEM Responsibilities to comply with FCC Regulations

The rebel UI Modules have been certified for integration into products only by OEM
integrators under the following conditions:

1. The antenna(s) must be installed such that a minimum separation
Distance of 20 cm is maintained between the radiator (antenna) and all persons at all times.

2. The transmitter module must not be co-located or operating in conjunction with any other
antenna or transmitter.

As long as the two conditions above are met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end-product for any
additional compliance requirements required with this module installed (for example, digital
device emissions, PC peripheral requirements, etc.).

Whirlpool Corporation  2000 M-63  Benton Harbor, MI 49022

Rev 1.0 Page 13

IMPORTANT NOTE: In the event that these conditions cannot be met (for certain
configurations or co-location with another transmitter), then the FCC authorizations are no
longer considered valid and the FCC ID cannot be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.

3.2 End Product Labelling

The rebel UI Modules are labelled with FCC ID. If the FCC ID is not visible when the module
is installed inside another device, then the outside of the device into which the module is
installed must also display a label referring to the enclosed module. In that case, the final
end product must be labelled in a visible area or display the following:

“Contains FCC ID: A5UEICHRB01”
The OEM of the rebel UI Module must only use the approved antenna(s), which have been

certified with this module. The OEM integrator has to be aware not to provide information to
the end user regarding how to install or remove this RF module or change RF related
parameters in the user manual of the end product.
