REPORT No.SZ24080104S01
2. Device Category and RF Exposure Limit

Per user manual, based on 47 CFR 2.1091, this device belongs to mobile device category with

General Population/Uncontrolled exposure.

Mobile Devices:

47 CFR 2.1091(b)

For purposes of this section, a mobile device is defined as a transmitting device designed to be

used in other than fixed locations and to generally be used in such a way that a separation distance

of at least 20 centimeters is normally maintained between the transmitter's radiating structure(s)

and the body of the user or nearby persons. In this context, the term "fixed location" means that the

device is physically secured at one location and is not able to be easily moved to another location.

Transmitting devices designed to be used by consumers or workers that can be easily re-located,

such as wireless devices associated with a personal computer, are considered to be mobile

devices if they meet the 20 centimeter separation requirement.

General Population/Uncontrolled Exposure:

The general population/uncontrolled exposure limits are applicable to situations in which the

general public may be exposed or in which persons who are exposed as a consequence of their

employment may not be made fully aware of the potential for exposure or cannot exercise control

over their exposure. Members of the general public would come under this category when

exposure is not employment-related; for example, in the case of a wireless transmitter that

exposes persons in its vicinity. Warning labels placed on low-power consumer devices such as

cellular telephones are not considered sufficient to allow the device to be considered under the

occupational/controlled category, and the general population/uncontrolled exposure limits apply to

these devices.

Note 1: According to KDB 447498, MPE assessment is based on source-based time-averaged maximum conducted output power of the RF channel requiring assessment, adjusted for tune-up

tolerance, and the minimum test separation distance required for the exposure conditions.

Note 2: The maximum average power refers to report (Report No.: SZ24080104W01/W02).

Note:

1. According to KDB 447498, MPE assessment is based on source-based time-averaged

maximum conducted output power of the RF channel requiring assessment, adjusted for

tune-up tolerance, and the minimum test separation distance required for the exposure

conditions.

2. MPE calculate method

S = PG/4R²

Where: S= Power density (in appropriate units, e.g. mW/cm²) P = Time-average maximum tune-up power (in appropriate units, e.g. dBm) G = numeric gain of the antenna (in appropriate units, e.g. dBi) R = Separation distance to the centre of radiation of the antenna (20cm)

Simultaneous Transmission Assessment: According to the user manual, the WLAN transmitters in the device cannot operate simultaneously, therefore simultaneous transmission analysis is not required.

Conclusion: According to 47 CFR §2.1091, this device complies with human exposure basic restrictions.
