The radio output is connected to an antenna using a wave guide type of trace to minimize losses because of the two-layer structure of the PCB. The front-end has a discrete RF-filter to comply with harmonic emission regulations. The radio uses an XO with integrated frequency control via built-in thermistor to cover the wide temperature range. If a stable slow clock source is needed, oscillators can be calibrated in runtime instead of using a dedicated 32 kHz clock. 1.4 Type approval markings The ICC-A-1 module has a FCC ID and Industry Canada (IC) number silkscreen printing for reference located at the bottom. The host shall be labelled with Contains Transmitter Module FCC ID: XXX and IC: XXX • ICC-A-1 • FCC ID: FHO-ICC-A-1 • IC:10912-ICCA1 Figure 3 - Silkscreen printing

It is mandatory to follow the described antenna integration design rules to ensure acceptable and correct radiated performance. Deviation from the antenna integration guidelines should be review both from a product perspective but also from a regulatory point of view. The antenna gain is -3.6 dBi.

During peak load transients, power supply can be up to 100mA when using high power mode. The product designer shall verify unconditional stability during peak load to secure that voltage is not dropping below 2.1V. The actual design of the regulator affects the decoupling capacity. Make sure that no noise is injected via the power supply that can impact the analogue parts of the radio. 3.2 Coin cell battery operation ICC-A-1 can be operated from a single 3.0V coin cell battery. A minimum of sustaining 2.1V during all peak transients until battery end of life is required to guarantee proper operation. Make sure to fulfil the below requirements: • Add enough decoupling to the device to avoid brown out during transient load in TX burst. 20uF < 200uF. Soldered

Other electronic functions not associated with the certified module or certified transmitter requires additional equipment authorization. A host product itself is required to comply with all other applicable FCC equipment authorization regulations, requirements, and equipment functions that are not associated with the transmitter module portion. To ensure compliance for all non-transmitter functions, a host product manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. ICC-A-1 fulfils the RF exposure requirements as portable limb-worn device and as mobile device, with a separation distance equal to or more than 20 cm between product and users body in normal operation. ICC-A-1 must only be installed in portable limb-worn devices (not body worn) or in mobile devices with a separation distance equal to or more than 20 cm from users body under normal operations. If ICC-A-1 is installed in a mobile device (host), a special text needs to be added in the host user manual. This text needs to include information regarding the separation distance and advise the end user that it is not allowed to be closer than 20 cm from the device during normal operation. The text needs to be in both English and French language. 5.2 User manual User manual for license-exempt radio using the ICC-A-1 module needs to contain ICC-A-1 regulatory information. 5.3 Label The label for license-exempt radio using the ICC-A-1 module shall be printed separately and needs to contain the FCC ID/ISED certification number clearly visible on the product.
