No. A 3073-6601 Sheet 1 of 2 RF Venue Tune Up Procedure, Combine 6 6/22/2024 2 of 2 3073-6601 Rev 1 1. FCC ID This Tune Up Procedure applies to FCC ID 2BDOJ-COMBINE6 2. Purpose This document is a procedure for verifying proper operation of the RF Venue Combine6 In-Ear Monitor Transmitter Combiner. It is intended to satisfy the requirements for a Tune Up Procedure for licensed devices under Part 74 per 47 CFR Part §2.1033(c)(12). There are no tuning adjustments or other calibration steps required during manufacturing or use for the device. All RF circuits are implemented with fixed values. During manufacturing, each device is tested to ensure proper operation and that the output power is within specified limits as documented in the referenced emissions test report. 3. Reference Documents Combine 6 User Guide Emissions Test Report 105431768BOX-001 4. Test Equipment Requirements The following equipment is required to perform this procedure. All equipment used must be calibrated per the manufacturer’s specifications. Equivalent equipment may be substituted with approval of the quality control manager. Keysight FieldFox RF Analyzer N9912A. An equivalent signal generator, spectrum analyzer or other RF measuring device may be used provided it is approved by the quality manager and supports the following:  Frequency range to cover from 400 MHz to 700 MHz minimum  Output power of +1 dBm at 539 MHz Two RG-58 50-ohm BNC cables, 3’ long. Cables should have a known loss and be periodically calibrated. 5. Procedure  Set the RF Analyzer to generate a nominal +1 dBm continuous wave tone at 539 MHz. This is the TEST INPUT signal.  Connect the generator port of the analyzer to the measurement port with one of the 3’ RG-58 cables (INPUT CABLE) and record the measured power Pin. Confirm Pin is greater than +0 dBm.  Power on the DUT. Disconnect the INPUT CABLE from the analyzer’s measurement port and connect it to ACTIVE INPUT channel 1 of the DUT. The other input ports are left disconnected.  Connect the ACTIVE OUTPUT port of the DUT to the analyzer’s measurement port using a second 3’ RG-58 cable with known loss Loc (dB).  Record the measured output power Pout in dBm. Repeat for each channel.  Calculate the DUT gain per channel as follows: Gdut (dB) = Pout (dBm) – Pin (dBm) + Loc (dB) 6. Test Limits The DUT gain shall be between -3 and +1 dB for each channel. Out-of-specification units shall be dispositioned as non-conforming material per RF Venue standard procedure.

A mobile device is defined as a transmitting device designed 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 structurer(s) and the body of the user or nearby persons. The evaluation indicated in section 2.0 were performed on the product constructed as described in section 4.0. The remaining sections are the verbatim text from the actual evaluation during the investigation. These sections include the evaluation name, the specified Method, and Results. No additions, deviations, or exclusions have been made from the standard(s) unless specifically noted. Based on the results of our investigation, we have concluded the product evaluated complies with the requirements of the standard(s) indicated. The results obtained in this report pertain only to the item(s) evaluated. Intertek does not make any claims of compliance for samples or variants which were not evaluated. 2 Evaluation Summary Section Test full name Result 3 Client Information - 4 Description of Equipment Under Evaluation and Variant Models - 5 System Setup and Method - 6 Power Density Calculation (FCC §1.1310) Compliant 7 Revision History - Intertek Report Number: 105431768BOX-001.1 Issued: January 23, 2024 Revised: March 4, 2024 Non-Specific Radio Report Shell Rev.
