1.1 Applicant and Manufacturer Information

1.2 Equipment Under Test (EUT) Description

1.3 Photographs of the EUT

1. EUT Front View: A black wireless game controller is shown from the front. It features two analog sticks, a directional pad, four face buttons (labeled X, Y, A, B), and a central brand logo. A ruler is placed alongside for scale, indicating dimensions.

2. EUT Back View: The rear view of the black wireless game controller is displayed, showing its ergonomic grips and design. A ruler is also present for scale.

1.4 Identification of all used EUT

The EUT identity consists of numerical and letter characters. The letter character indicates the test sample, and the following two numerical characters indicate the software version of the test sample.

2. Device Category and RF Exposure Limit

Per user manual, this device is a Flydigi APEX Wireless Controller. Based on 47CFR §2.1093, this device belongs to portable device category with General Population/Uncontrolled exposure.

Portable Devices:

47CFR §2.1093(b)

For purposes of this section, a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user.

GENERAL POPULATION / UNCONTROLLED EXPOSURE

47CFR §2.1093(d) (2)

Limits for General Population/Uncontrolled exposure: 0.08 W/kg as averaged over the whole-body and spatial peak SAR not exceeding 1.6 W/kg as averaged over any 1 gram of tissue (defined as a tissue volume in the shape of a cube). Exceptions are the hands, wrists, feet and ankles where the spatial peak SAR shall not exceed 4 W/kg, as averaged over any 10 grams of tissue (defined as a tissue volume in the shape of a cube). General Population/Uncontrolled limits apply when the general public may be exposed, or when persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or do not exercise control over their exposure. Warning labels placed on consumer devices such as cellular telephones will not be sufficient reason to allow these devices to be evaluated subject to limits for occupational/controlled exposure in paragraph (d)(1) of this section.

3. Measurement of RF Output Power

1. Output power

Bluetooth (LE)

2.4G

Note: According to KDB 447498 Section 4.3, SAR test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions.

4. RF Exposure Evaluation

The device only incorporates a Flydigi APEX Wireless Controller, so standalone SAR evaluation is required for Bluetooth and simultaneous SAR is not required.

Standalone transmission SAR evaluation

According to KDB 447498 section 4.3.1, the 1-g SAR test exclusion thresholds at test separation Distances ≤ 50 mm are determined by:

[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0

The maximum tune-up limit power is 2.51mW @ 2.480GHz.

When the Wireless Controller is used on the hand/head, so use 5mm as the most conservative minimum test separation distance.

[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] = 0.78 ≤ 3.0

So SAR evaluation is not required for this device.

Note: Declaration of the tune-up limit is 4.0dBm.
