Attention: Certification reviewer RE: Request for Confidentiality FCC ID: ZBC-SH207AG To Whom It May Concern: Permanent Confidentiality [Complete this section if permanent confidentiality is requested] Request to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: [Select one or more of items below, as appropriate] Schematics Block Diagrams Operational Description Tune-up Procedure Parts List Internal Photos (see note) Users Manual (see note) Note 1: Internal Photos may be held confidential 1) if the circuit board or internal components are not accessible to users.

INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a Smart Tag / Smart Tag Card with Bluetooth 5.0 BLE function operating in 2402-2480MHz. The EUT is powered by DC 3.7 V from battery. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna Modulation Type: GFSK Antenna Gain: 2.089 dBi Bluetooth Version: 5.3 BLE (Single Mode) The nominal conducted output power specified: 7.0 dBm (±1.0dB) The nominal radiated output power (e.i.r.p) specified 9.0 dBm (±1.0dB) According to the KDB 447498 V06: The minimum conducted output power for the EUT is 6.06 dBm in the frequency 2.402GHz which is within the production variation. The maximum conducted output power for the EUT is 7.29 dBm in the frequency 2.480GHz which is within the production variation. which is within the production variation. The maximum conducted output power specified is 7.29 dBm= 5.36 mW The source- based time-averaging conducted output power= 5.36 mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.52 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
