The steps to install the crankset vary between models. Follow the manufacturer’s instructions, or consult your local bike mechanic for assistance. Installation instructions for your new Shimano crankset are included with the Ride Ready option. 1. INTRO 2 2. Wake up PRECISION 3 by rotating the crank 3-4 times. 3. Pair your power meter with a compatible display unit using ANT+ or Bluetooth. Refer to Section 2.3 for full instructions. 1.3Get ready to ride (Quick Start) 1. Connect to the Apple Find My app (Android users skip this step) Refer to Section 5 for full instructions. (a) Remove and reinstalling the battery on your Non-Drive Side PRECISION 3 Powermeter three times (x3) to trigger Apple Find My pairing mode. (b) From the Apple Find My app, add your PRECISION 3 Powermeter. 1. INTRO 3 4. Perform a zero offset (some units refer to this as calibration). Refer to Section 3 for full instructions. (a) Unclip and dismount. Hold the bike upright and stationary, and position the crank arms at 12 and 6 o’clock, with the non-drive side crank arm down. (b) Select “Zero” or “Calibrate” on your display unit. ZERO-OFFSET CALIBRATE 12 6 NON-DRIVE SIDE DRIVE SIDE 2.

Product Precision 3 Powermeter – PML300 & PMR300 Standard(s) FCC KDB 447498 v07 Page 2 of 7 Report Issued: 5/3/2023 Report File #: 716901274-000 - RF Exposure © TÜV SÜD Canada Inc. This test report shall not be reproduced except in full, without written approval of TÜV SÜD Canada Inc. RF Exposure Calculation (FCC) Purpose The purpose of this test is to ensure that the RF energy transmitted at a specified operating distance from the human body meets the criteria to be exempt from routine evaluation. The RF Exposure values are calculated based upon measurements obtained during testing and are compared to the applicable exposure limits for individual RF sources. If multiple RF sources are used within a host product, and they operate simultaneously, an additional exemption criterion based on total exposure from multiple RF sources is also applied. If the exemption criteria are not met, the RF sources may be required to undergo routine evaluation for RF Exposure. Limit(s) and Method The test method and exemption limits are defined in FCC KDB 447498 and FCC 1.1307(b)(3) and are applicable to both unintentional and intentional RF sources, whether portable, mobile, or fixed installations. Individual RF Sources For individual sources, the following three exemption criteria options are defined. Any of the three options may be used to determine the RF source to be exempt from routine evaluation if it meets the corresponding exemption limit. Defined in FCC 1.1307(b)(3)(i)(A), Exemption Criteria Option A is based on the maximum time-averaged output power. The requirement is that this measurement must not exceed 1mW, regardless of separation distance, and in the frequency range of 100kHz-100GHz. Client 4iiii Innovations Inc. Product Precision 3 Powermeter – PML300 & PMR300 Standard(s) FCC KDB 447498 v07 Page 3 of 7 Report Issued: 5/3/2023 Report File #: 716901274-000 - RF Exposure © TÜV SÜD Canada Inc. This test report shall not be reproduced except in full, without written approval of TÜV SÜD Canada Inc. Defined in FCC 1.1307(b)(3)(i)(B), Exemption Criteria Option B is based on SAR using the measurement of maximum time-averaged output power or ERP, whichever is greater. This option is applicable to separation distances of 0.5cm-40cm and in the frequency range of 300MHz-6GHz. The limit is defined below: Defined in FCC 1.1307(b)(3)(i)(C), Exemption Criteria Option C is based on MPE using the ERP measurement. This option is only applicable for separation distances greater than or equal to the wavelength of the frequency under consideration divided by 2π, and in the frequency range of 300kHz-100GHz. The limit is defined below: Client 4iiii Innovations Inc.

This test report shall not be reproduced except in full, without written approval of TÜV SÜD Canada Inc. Multiple RF Sources For multiple sources, the following two exemption criteria options are defined. Exemption criteria for multiple RF sources is applicable if the EUT contains any RF sources that may operate simultaneously. Defined in FCC 1.1307(b)(3)(ii)(A), the results of only the exemption criteria option A calculation for for each individual RF source shall be used to determine exemption for multiple RF sources. The criteria for exemption are defined below: 1.If the separation distance between each individual RF source is at least 2 centimeters, and each individual source meets exemption criteria option A for single RF sources. 2.If the sum of maximum output power of multiple RF sources is less than 1mW, the sources can be treated as a single source and are exempt based on exemption criteria option A for single RF sources. Defined in FCC 1.1307(b)(3)(ii)(B), the exemption ratios calculated for each individual RF source shall be used to calculate the Total Exposure Ratio. This calculation includes exemption criteria calculated using Exemption Criteria Options B or C, or the measurement results of any RF source that may have been subject to routine evaluation. The limit is defined below: Client 4iiii Innovations Inc.

This test report shall not be reproduced except in full, without written approval of TÜV SÜD Canada Inc. Results The EUT is exempt from routine evaluation of RF exposure based on the following calculations: Single RF Source 1 Analysis – 2.4GHz BLE Transmitter The 2400MHz BLE Transmitter has maximum output power at the low channel frequency of 2402MHz. The values related to the PML300 model are used as a worst-case representative of both the PML300 and PMR300. The separation distance is taken as 5mm for a worst-case scenario. Frequency (MHz): 2402 Separation Distance (cm): 0.5 Antenna Gain (dBi): -7 Conducted Power (dBm): 4.15 Conducted Power (mW): 2.60 ERP (mW): 0.52 Exemption Criteria Option A: Threshold Power = 1mW 2.60mW > 1mW Option A is not applicable. Exemption Criteria Option B: Threshold Power = 2.79mW 2.60mW < 2.79mW Option B is applicable. Contribution Ratio = 2.60/2.79 = 0.933 Exemption Criteria Option C: λ/2π = 0.02m R = 0.005m 0.005m < 0.02m Option C is not applicable. Therefore, the RF source is exempt from routine evaluation based on Exemption Criteria Option B with contribution ratio of 0.933. Client 4iiii Innovations Inc.
