FCCRFEXPOSUREREQUIREMENTS

Standards and Regulatory Compliance

Standardsandcertification

The EUT conforms to the following standards and certification requirements:



Vilnius,

20/23

GSM850/1900, Bluetooth

FCC

❒ 47 CFR Part 1 – RF radiation exposure limits

❒ 47 CFR Part 2 – Equipment authorization

❒ 47 CFR Part C – Bluetooth

FCCcertificationrequirements.

According to the definition of mobile and fixed ntena is described in Part 2.1091(b), this

ntena is a mobile ntena.

And the following conditions must be met:

1. The EUT is a mobile ntena; maintain at least a 20 cm separation between the EUT and

the user’s body and must not transmit simultaneously with any other ntena or

transmitter.

2. The ntena is only for fixed operation mode. (A Class II Change would be required for

near-body Host applications.)

3. A label with the following statements must be attached to the host end product: This

ntena contains Tx FCC ID:2AJLOTM2500TLT

4. To comply with FCC regulations limiting both maximum RF output power and human

exposure to RF radiation, maximum ntena gain (including cable loss) must not exceed:

❒

GSM850/1900 band < 2 dBi

❒

Bluetooth <1.69 dBi

5. This module must not transmit simultaneously with any other ntena or

transmitter

6. The host end product must include a user manual that clearly defines operating

requirements and conditions that must be observed to ensure compliance with current

FCC RF exposure guidelines.



Vilnius,

21/23

For portable devices, in addition to the conditions 3 through 6 described above, a separate

approval is required to satisfy the SAR requirements of FCC Part 2.1093

If the device is used for other equipment that separate approval is required for all other

operating configurations, including portable configurations with respect to 2.1093 and

different antenna configurations.

For this device, OEM integrators must be provided with labeling instructions of finished

products. Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:

A certified modular has the option to use a permanently affixed label, or an electronic

label. For a permanently affixed label, the module must be labelled with an FCC ID -

Section 2.926 (see 2.2 Certification (labelling requirements) above). The OEM manual

must provide clear instructions explaining to the OEM the labelling requirements, options

and OEM user manual instructions that are required (see next paragraph).

For a host using a certified modular with a standard fixed label, if (1) the module’s FCC

ID is not visible when installed in the host, or (2) if the host is marketed so that end users

do not have straightforward commonly used methods for access to remove the module so

that the FCC ID of the module is visible; then an additional permanent label referring to the

enclosed module:“ Contains Transmitter Module FCC ID:2AJLOTM2500TLT” or “Contains

FCC ID:2AJLOTM2500TLT” must be used. The host OEM user manual must also contain

clear instructions on how end users can find and/or access the module and the FCC ID.

The user manual or instruction manual for an intentional or unintentional radiator shall

caution the user that changes or modifications not expressly approved by the party

responsible for compliance could void the user's authority to operate the equipment. In

cases where the manual is provided only in a form other than paper, such as on a

computer disk or over the Internet, the information required by this section may be

included in the manual in that alternative form, provided the user can reasonably be

expected to have the capability to access information in that form.

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.

Caution: Changes or modifications not expressly approved by the manufacturer could void

the user’s authority to operate the equipment.

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.

FCCRFexposurerequirements

1. Radiated transmit power must be equal to or lower than that specified in the FCC Grant of

Equipment Authorization for FCC ID:2AJLOTM2500TLT.

2. To comply with FCC regulations limiting both maximum RF output power and human

exposure to RF radiation, maximum antenna gain (including cable loss) must not exceed:

❒GSM850/1900 band <2 dBi

❒Bluetooth <1.69 dBi

3. This module must not transmit simultaneously with any other antenna or transmitter.

4. To ensure compliance with all non-transmitter functions the host manufacturer is

responsible for ensuring compliance with the module(s) installed and fully operational. For

example, if a host was previously authorized as an unintentional radiator under the

Declaration of Conformity procedure without a transmitter certified module and a module is

added, the host manufacturer is responsible for ensuring that the after the module is

installed and operational the host continues to be compliant with the Part 15B unintentional

radiator requirements.
