Operational Use Conditions

Note: If your module has professional user condition limitations, please include the following statement in your product instructions: "Module has professional users use condition limitations. Host product manufacturer please ensure giving such warning like 'Product is limited to professional users use' in your product's instruction."

Antenna Information

2.4 Antenna Used

2.5 Trace Antenna Designs Information

[If using a trace antenna, otherwise, this part may be ignored and deleted]

Provide trace boundary limits, thickness, length, width, shape(s), dielectric constant, and impedance, etc., any parameters permitting host manufacturers to design the PCB layout.

Provide Test procedures for design verification and Production.

Notice to Host Product Manufacturer

Any deviation(s) from the defined parameters of the antenna trace, as described by this instruction, require the host product manufacturer to notify the module provider of the desired change. In this case, a Class II permissive change application is required to be filed by the module provider, or the host manufacturer can take responsibility through the change in FCC ID and IC ID (new application) procedure followed by a Class II permissive change application.

Limited Module Procedures

2.6 Notice to Host Manufacturer when Installing Module

This notice applies when installing the module and intending to use it. The module contains FCC ID: 2A9F9HL3215SG and IC: 29823-HL3215SG.

If the Module is approved as a Limited Module, please follow the guidance below:

If a modular transmitter is approved as a "limited module," the module manufacturer is responsible for approving the host environment in which the limited module is used. The manufacturer of a limited module must describe, both in the filing and in the installation instructions, the alternative means used to verify that the host meets the necessary requirements to satisfy the module's limiting conditions.

A limited module manufacturer has the flexibility to define its alternative method to address conditions that limit the initial approval, such as shielding, minimum signalling amplitude, buffered modulation/data inputs, or power supply regulation. The alternative method could include the module manufacturer reviewing detailed test data or host designs prior to granting the host manufacturer approval.

This limited module procedure is also applicable for RF exposure evaluation when it is necessary to demonstrate compliance in a specific host. The module manufacturer must state how control of the product into which the modular transmitter will be installed will be maintained to ensure full compliance of the product at all times. For additional hosts other than the specific host originally granted with a limited module, a Class II permissive change is required on the module grant to register the additional host as a specific host also approved with the module.

Labelling Instructions for Host Product Integrator

Please note that if the FCC and IC identification number 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. For FCC, this exterior label should follow "Contains FCC ID: 2A9F9HL3215SG". In accordance with FCC KDB guidance 784748 Labeling Guidelines. For IC, this exterior label can use wording "Contains IC: 29823-HL3215SG".

§ 15.19 Labelling requirements shall be complied on the end-user device. Labelling rules for special devices, please refer to §2.925, § 15.19 (a)(5) and relevant KDB publications. For E-label, please refer to §2.935.

Installation Notice to Host Product Manufacturer

The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install the module. The module is limited to installation in mobile applications; a separate approval is required for all other operating configurations, including portable configurations with respect to §2.1093 and different antenna configurations. The device has an integrated trace antenna; the host manufacturer cannot change the antenna.

FCC Part 15B Compliance Requirements for Host Product Manufacturer

This modular transmitter is only FCC authorized for the specific rule parts listed on our grant. The host product manufacturer is responsible for compliance with any other FCC rules that apply to the host not covered by the modular transmitter grant of certification.

The host manufacturer shall ensure that the host product, which is installed and operating with the module, is compliant with Part 15B requirements.

Please note that for a Class B or Class A digital device or peripheral, the instructions furnished in the user manual of the end-user product shall include a statement set out in §15.105 Information to the user, or a similar statement, and place it in a prominent location in the text of the host product manual. Original texts are as follows:

For Class B

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 or more 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.

For Class A

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense.
