USER MANUAL | FCC ID: 2AD9E-BTM

JL Audio QCC5124 Module
FCC ID: 2AD9E-BTM
IC: 25930-BTM

FCC Part 15 Compliance Statement

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.

JL Audio, Model Number, FCC ID: 2AD9E-BTM is seeking modular approval. The radio meets
the requirements for modular approval as detailed in FCC 15.247. Compliance to each of the
requirements is described below:

1. “The modular transmitter must have its own RF shielding.” The radio portion of the

module is contained in its own RF shielding. The shielding is installed at the factory.
Please see the Internal Photos exhibit.

2. “The modular transmitter must have buffered modulation/data inputs.” The EUT has

buffered data inputs to insure compliance with Part 15 requirements under conditions of
excessive data rates or over-modulation. Please see the Schematics exhibit.

3. “The modular transmitter must have its own power supply regulation.” The EUT has its

own power supply regulation to insure compliance with Part 15 requirements regardless
of the quality or level of external DC supplying the module from the host unit. Please see
Schematics exhibit. Also, the technical report exhibit contains AC power line conducted
emissions data taken with the EUT powered from a linear power supply that contains no
EMC suppression components.

4. “The modular transmitter must comply with the antenna requirements of Section 15.203

and 15.204(c).” The EUT meets the FCC antenna requirements. Please see Antenna

information exhibit and internal photos exhibit.

5. “The modular transmitter must be tested in a stand-alone configuration.” The EUT was

tested in a stand-alone configuration. The module was greater than 10 cm from the host
device. Please see test setup photos exhibit and technical report exhibit.

6. “The modular transmitter must be labeled with its own FCC ID number.” The EUT is

labeled with its own FCC ID number. Please see FCC ID label & location exhibit. If the
FCC ID number will not be visible when the module is installed inside a host device,
another label with the FCC ID will be applied to the exterior of the host device.

7. “The modular transmitter must comply with any specific rule or operating requirements

applicable to the transmitter and the manufacturer must provide adequate instructions

along with the module to explain any such requirements.” The EUT is compliant with

all applicable FCC rules. Detail instructions for maintaining compliance are given in the
User Manual.

8. “The modular transmitter must comply with any applicable RF exposure requirements.”

The EUT is compliant with all applicable RF exposure requirements. Please see RF
Exposure Exhibit.

Changes to the Device

Changes or modifications not expressly approved by the manufacturer could void the user’s

authority to operate the equipment.

Device Antenna

Module shall be used with one of the following pre-certified antennas:
Yageo, ANTX100P001B24003, 4.4dBi, Trace
Yageo, ANTX100P112B24553, 2.2dBi, Patch
Yageo, ANTX100P011B24003, 2.2dBi, Trace

Attachment of any higher-gain antenna or other-patterned antenna is not permitted. Increases in
the shielded length of the antenna which do not increase its gain or change its emission pattern
are permitted. Modification of the module to install an antenna not approved for use voids the
user’s authority to operate the equipment.

Co-Location

This device and its antenna must not be co-located or operated in conjunction with another
transmitter or antenna.

Digital Device Integration

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.

Integration of this product into an end-device with various host modules will require re-testing for
Digital Device emissions compliance, as data lines from the module are connectable to host
devices. Compliance should be feasible and any failures in compliance will require adjustments to
the host device to resolve. Even when the host device does not have any oscillators or logic on
board which would independently trigger Digital Device requirements, digital device testing for
the product will be necessary due to those parts on the module.
