MAX 5V 210-208529 FCC ID: 2AKFED435 45 DEFUNC TRUE ANC Thanks for choosing Defunc TRUE ANC. Read this manual to optimize your experience. Enjoy your new earbuds! WHAT’S INCLUDED • Defunc TRUE ANC earbuds • Extra earplugs (size S/M/L) • USB-C charging case and cable GENERAL TIPS FOR TRUE WIRELESS EARBUDS • Because of interference with other Bluetooth devices, the earbuds can get disconnected from each other. If you experience this problem, put the earbuds in the charging case and close the cap. After a few seconds, open the cap and start using the earbuds again. • Hold the earbud stem when putting or adjusting the earbuds in your ears. This way you avoid touching the sensitive touch area which controls different functions. • The volume affects the capacity of the battery. If you play your music with lower volume, the battery life will last longer. • Pause between each touch control command, e.g. wait 1 second between each volume control tap to further increase/decrease volume.

Active noise cancellation (ANC) mode actively cancels surrounding noise. 2. Transparency Mode lets surrounding sounds into the earbuds. 3. Gaming Mode gives you a low latency of 55 ms. 4. Music mode for an enhanced music experience. It is the default when the earbuds are turned on. Download the Defunc app where you find your apps and follow the instruc- tions to register your account. You can also use your earbuds without the app (for our default audio settings that fits all music genres) Defunc app gives you the possibility to choose EQ settings or to create your own. You can also switch between different modes (ANC/Transparency/ GAMING/Music) and enjoy a number of other features to enhance your listening experience. DEFUNC APP 89 1. Make sure the earbuds are fully charged. Do this by charging the earbuds in the charging case until all 4 white lights on the charging case are lit for 5 seconds and then turn off. 2. Open the charging case. The earbuds will automatically power on and pair with each other. 3. T ake out the earbuds. When blue/red lights flash alternately, the earbuds are ready to pair with your device. 4. Turn on the Bluetooth function on your device. Select Defunc TRUE ANC in the Bluetooth list to pair the earbuds with the device. • The earbud lights turn off when the earbuds are paired. • The earbuds will automatically pair with a previously connected device when taken out of the charging case again. POWER ON There are two ways to turn the earbuds on: 1. Open the charging case for auto-power on after about 1 second. 2. Press each earbud for 3 seconds until you hear the on-sound or white lights flash 3 times. POWER OFF There are three ways to turn the earbuds off and one way they auto-power off: 1. Put the earbuds back in the charging case and close the cap. 2. Press either earbud for 5 seconds until you hear the off-sound or see r ed lights flash 3 times. 3. Auto-power off will be activated after 5-6 minutes without a connected device. 1011 TOUCH CONTROL FUNCTIONS Tap or press the earbud touch area to control different functions. Switch sound modes: Press the right earbud for 3 seconds to switch from normal mode to transparency mode. 3 seconds again to switch from transparency mode to active noise cancellation (ANC) and 3 seconds again to go back to normal mode. Press the left earbud for 3 seconds to switch from music mode to gaming mode, and 3 seconds again to go back to music mode. If the earbuds are turned off, the last setting will be the default when turned back on. Power on: Open the charging case for auto-power on or press each earbud for 3 seconds. Power off: Put the earbuds back in the charging case and close the cap. Or press either earbud for 5 seconds. Auto-power off will be activated after 5-6 minutes without a connected device.

Applicable Standards FCC Part 2(Section 2.1093) FCC KDB 447498 D04 Interim General RF Exposure Guidance v01 2. Exposure Evaluation of Portable or Mobile Devices Human exposure to RF emissions from portable devices (47 CFR §2.1093), as defined by the FCC, must be evaluated with respect to the FCC-adopted limits for SAR. Evaluation of mobile devices, as defined by the FCC, may also be performed with respect to SAR limits, but in such cases it is usually simpler and more cost-effective to evaluate compliance with respect to field strength or power density limits. For certain devices that are designed to be used in both mobile and portable configurations similar to those described in 47 CFR §2.1091(d)(4), such as certain desktop phones and wireless modem modules, compliance for mobile configurations is also satisfied when the same device is evaluated for SAR compliance in portable configurations. The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 300 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. FCC ID: 2AKFED435 EST Technology Co., Ltd Report No. ESTE-R2305038 Page 3 of 3 3.
