Western Digital MR-2400MB WD Green Internal Solid State Drive User Manual

Western Digital MR-2400MB WD Green Internal Solid State Drive

Specifications

• Module Type: RF SiP MR-2400MB
• Frequency Band: 2.4GHz
• Mounting Type: Surface Mount Device
• Outline Size: 6.5 x 6.5 mm
• Identifier Marking Area Size: 4.0 x 6.0 mm
• Compliance: FCC, CE-Red, MIC, NCC

Installation Procedure

1. Ensure that the host device’s interface specification matches the module’s requirements.
2. Solder the RF SiP MR-2400MB module onto the end product using surface mount technology.
3. Ensure the module is securely attached and not accessible to the end-user.

Identifier Marking
The module’s identifier marking is located on a sticker and includes a readable module name and the company logo. The marking area size is 4.0 x 6.0 mm, which does not allow printing of FCC and IC IDs. Instead, these IDs are printed on the cardboard box and the module’s user manual.

User’s manual

• The module is only approved for use by the grantee in its own products and not intended for sale to third parties. The user manual for integration instructions are internal confidential manufacturing documents. For the details about this module, please refer to the specification sheet of the module.
• This module should be installed in the host device according to the interface specification (installation procedure).

Identifier marking for 2.4GHz band RF SiP MR-2400MB modules

• The module is a Surface Mount Device SiP (System in Package) soldered onto the end product and is not acessible to the end-user. It is not possible for the end-user to replace or remove the module.
• The outline size is 6.5 x 6.5 mm. The identification marking is made by sticker (see Figure-1)
• Readable module name
  Company Logo

The size of the marking area is only 4.0 x 6.0 mm, thus the size of the module/label makes it impossible to print the FCC and IC IDs on the identifier label in a print size of 4 points or larger. Instead the FCC, CE-Red, MIC and NCC IDs are printed on the cardboard box as well as the modules user manual of the end devices.

2. Regulatory information for FCC(U.S.A.)
   The MR-2400MB module is FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and 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. The final host product still requires Part 15 Subpart C compliance testing with the modular transmitter installed.
   Fine tuning of return loss etc. can be performed using a matching network. However, it is required to check “Class1 change” and “Class2 change” which the authorities define then.
   The following information must be indicated on the host device of this module;

Contains Transmitter Module FCC ID: 2AJE9MR-2400MB
or

Contains FCC ID: 2AJE9MR-2400MB

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, and
2. this device must accept any interference received, including interference that may cause undesired operation.

• If it is difficult to describe this statement on the host product due to the size, please describe in the User’s manual.

The following statements must be described on the user manual of the host device of this module;

FCC CAUTION

• Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
• This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.
• This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment is not certified as type of the portable device with FCC
• Rules. Then, please use within specification of this product and have a separation distance of minimum 20 mm between the user and/or bystander and the antenna and /or radiating element.

Digital devices used EXCLUSIVELY as industrial, commercial or medical test equipment. “Test equipment” includes devices used for maintenance, research, evaluation, simulation and other analytical or scientific applications in areas such as industrial plants, public utilities, hospitals, universities, laboratories, automotive service centers and electronic repair shops.
If the final host is installed at the areas that are not subject to 15.103(c) exempted devices from Part 15 subpart B, it requires Part 15 Subpart B compliance testing.

FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247
The devices must be installed and used in strict accordance with the manufacturer’s instructions as described in the user documentation that comes with the product.”
