Introduction Thank you for purchasing ISOtunes® FREE 2.0 Bluetooth ® earbuds. These earbuds have been specifically designed for use in noisy environments – allowing you to block out much of the surrounding noise so that you can listen to your music or talk on the phone with less interruption. Controls [See the Quick Start Guide] Power On/Off Method 1 Power ON: Remove earbuds from charging case. Power OFF: Place earbuds into charging case. Method 2 Power ON: In OFF mode, press and hold multi-function button (MFB) for 3 seconds. Power OFF: In ON mode, press and hold MFB for 6 seconds. Bluetooth ® Pairing After powering on, the earbuds will automatically enter Bluetooth ® Pairing Mode. Look for quick red and blue flashes from the earbud as a confirmation. Open the Bluetooth ® settings on your device. Search for “ISOtunes FREE 2.0”. Pair and connect. You will hear “Bluetooth ® Connected” once connected. Charging There are three batteries to charge: 1. Charging Case Battery 2. Left Earbud Battery 3. Right Earbud Battery Charging the Case Insert USB type C charging cable into the charging case. The charging case battery indicator light will start flashing to indicate charge level. Charging the Earbuds Place earbuds into the charging case. The earbuds’ red indicator light should be solid red, indicating that the earbuds are charging. Only charge your ISOtunes FREE 2.0 with a Maximum 5 Volt charger. Using a charger higher than 5 Volts could be dangerous and may damage your ISOtunes product. Be especially careful with “quick charge” or “turbo charge” chargers, which often supply 9, 12, or 15 Volts. Your ISOtunes FREE 2.0 cannot be charged at voltage levels above 5 volts. Noise Attenuation This product has been tested to the European Safety Standard EN 352-2:2020 and the ANSI S3.19-1974 standard for a hearing protector, with a Single Number Rating (SNR) of 32 dB and a Noise Reduction Rating (NRR) of 25 dB. Full testing details are available in the Noise Attenuation section of this booklet. ANSI S3.19-1974 The level of noise entering a person’s ear, when ISOtunes® FREE 2.0 earbuds are worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the Noise Reduction Rating (NRR). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed EN 5 instructions for proper fitting. A1: Frequency (Hz) A2: Mean Attenuation (dB) A3: Standard Deviation (dB) Example: 1. The surrounding noise level measured at the ear is 100 dB. 2. The NRR of ISOtunes® FREE 2.0 is 25 dB. 3. The noise level entering the ear is approximately equal to 75 dB. Please note that the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise, such as gunfire. EN 352 B1: Frequency (Hz) B2: Mean Attenuation (dB) B3: Standard Deviation (dB) B4: Assumed Protection Value (APV) (dB H = Hearing protection estimation for high frequency sounds (f ≥ 2000Hz) M = Hearing protection estimation for medium frequency sounds (500 Hz < f < 2000Hz) L = Hearing protection estimation for low frequency sounds (f ≤ 500Hz) SafeMax™ Technology ISOtunes® FREE 2.0 incorporates SafeMax™ Technology, therefore its volume output has been limited to 85 decibels (IT-73 & IT-74), or 79 decibels (IT-72) .

BLOCK DIAGRAM OF LINE CONDUCTED EMISSION TEST EUT & Support Units Report No.: AGC01082220501FE03 Page 66 of 67 14.3. PRELIMINARY PROCEDURE OF LINE CONDUCTED EMISSION TEST 1. The equipment was set up as per the test configuration to simulate typical actual usage per the user’s manual. When the EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on the ground plane as per ANSI C63.10 (see Test Facility for the dimensions of the ground plane used). When the EUT is a floor-standing equipment, it is placed on the ground plane which has a 3-12 mm non-conductive covering to insulate the EUT from the ground plane. 2. Support equipment, if needed, was placed as per ANSI C63.10. 3. All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10. 4. All support equipment received AC120V/60Hz power from a LISN, if any. 5. The EUT received DC 5V power from adapter which received AC120V/60Hz power from a LISN. 6. The test program was started. Emissions were measured on each current carrying line of the EUT using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1 connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1 connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver. 7. Analyzer / Receiver scanned from 150 kHz to 30MHz for emissions in each of the test modes. 8. During the above scans, the emissions were maximized by cable manipulation. 9. The test mode(s) were scanned during the preliminary test. Then, the EUT configuration and cable configuration of the above highest emission level were recorded for reference of final testing. 14.4. FINAL PROCEDURE OF LINE CONDUCTED EMISSION TEST 1. EUT and support equipment was set up on the test bench as per step 2 of the preliminary test. 2. A scan was taken on both power lines, Line 1 and Line 2, recording at least the six highest emissions. Emission frequency and amplitude were recorded into a computer in which correction factors were used to calculate the emission level and compare reading to the applicable limit. If EUT emission level was less – 2dB to the A.V. limit in Peak mode, then the emission signal was re-checked using Q.P and Average detector. 3. The test data of the worst case condition(s) was reported on the Summary Data page. 14.5. TEST RESULT OF LINE CONDUCTED EMISSION TEST N/A Note: The BT function cannot transmit when charging.
