Install the antennas as shown in the diagram. 2. Install the battery or connect the power adapter. 6 Product Installation 3. Mount the Hub on the tripod and secure it. ①② 7 Product Connection Single Hub Connection Condition One For headsets in the Solidcom C1 Pro - Roaming Hub package, since the Hub and headsets have already been paired at the factory, they can be used immediately after power-on. 8 2. A pop-up window appears, indicating a firmware version mismatch. Choose Yes to upgrade the headset. Product Connection Condition Two For previously purchased Solidcom C1 and Solidcom C1 Pro headsets, the Hub and headsets need to be manually paired before use. The pairing procedures are as follows. 1. Power on the Hub and headset, and then use a USB-A to USB-C cable to connect them. 9 Product Connection 3. After the upgrade is complete, a pop-up window appears on the Hub, prompting you to assign a number to the pairing headset. Numbers in yellow are in use and hence not selectable, while numbers in gray are selectable. Select an appropriate number and choose Confirm to complete the pairing process. 10 Product Connection Dual Hub Cascade Connection To ensure that headsets maintain connection across the signal areas of two cascaded Hubs connected via an RJ45 Port, strictly follow the steps below for a reliable cascade connection. 1. Before cascading the Hubs, power on all headsets and Hubs to be used. Ensure that all headsets remain powered on until the cascade connection is successfully established. Headset 1Headset 2 Headset 10 Headset 3 - 9 11 Note: Ensure that all headsets are powered on and connected to the corresponding Hub before cascading the Hubs. 2. When all headset indicators stop flashing and display a steady light, it indicates that the headsets have successfully connected to the respective Hub. Then, you can connect the Hubs using an Ethernet cable as shown in the diagram. Product Connection 12 Operation Group Configuration on Hub The Hub supports 6-group talking and role assignment. You can assign a specific type of role to each headset and configure the parameters for each type through the Hub, webpage, or app, thus obviating the need to manually configure each headset’s parameters. The procedures for group configuration on the Hub are as follows. 1. Long press the menu button on the Hub to enter the Menu interface. 2. Select Grouping to enter the Group Settings interface. Choose Custom to customize the number for each type of role. 13 Operation 3. The Hub supports a total of 10 preset roles: Production (head/member), Cam A (cameraman group A head/member), Cam B (cameraman group B head/member), Lighting (head/member), Grip (equipment team head/ member). Each role’s group and corresponding button (A/B) are in the table below. 4.Adjust the number for each type of role based on your ac tual needs, and select A uto-Gen t o save and apply the configuration to the headsets. For example, If yo u set the number for Production to 5, headsets 1-5 will be assigned to Production. If you set the number for Cam A to 4, headsets 6-9 will be assigned to Cam A, and so forth. 5. Distribute the headsets to the corresponding personnel and start work. 6.Privacy of communications may not be ensured when using this phone.

The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time-averaged power. For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form in Appendix B. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1). Table to § 1.1307(b)(3)(i)(C) - Single RF Sources Subject to Routine Environmental Evaluation f = frequency in MHz; R = minimum separation distance from the body of a nearby person (appropriate units, e.g., m); For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Bay Area Compliance Laboratories Corp.
