2AKFED42BBluetooth Headset

QUICK START GUIDE TRUE BASIC I want to reset my earbuds. How do I do that? 1. Turn off the Bluetooth function on close-by devices to avoid accidental pairing. 2. Take out the earbuds from the charging case. Turn off the earbuds by pressing each earbud for 5 seconds. 3. Turn on the earbuds by pressing each earbud for 3 seconds. Hold the earbuds close to each other. 4. Pairing is successful when you hear ”earbuds paired”. 5. Turn on the Bluetooth function on the device you want to pair your earbuds with and choose Defunc TRUE BASIC in the list of available devices. Can the earbuds be connected to two devices at the same time? No. They can only be connected to one device at a time only. Can I use one earbud and charge the other one in the charging case? Yes you can! How do I unpair the earbuds and my device? Go to the Bluetooth settings on your device and look for a text or graphic that reads ”disconnect pairing” or similar. Tap on that text/graphic to unpair. Why won’t the earbuds sync with my device? This can be due to a few different reasons. Please make sure... • ...the earbuds are turned on. • ...Bluetooth is turned off on your device. • ...that the earbuds aren’t connected to another device. • ...the earbuds have low battery. What should I know about Bluetooth interference? Remember that when the 10-meter Bluetooth range is measured, it’s measured between two points without any objects in the way blocking the signal. This means that even though you have your device in your back pocket, the connection might not be 100 percent. If you experience a bad connection, please make sure that as little objects as possible are in the way between your earbuds and your device, for example clothes and accessories in your bag. I would like to claim my Defunc product. What shall I do? If you receive your goods and discover that it is damaged, or have other defects, please contact customer service.

Plug the USB-C charging cable with the USB-C port on the charging case and plug the other end of the cable into a power source. Charging case and ear- buds can be charged simultaneously. Do note that the charging case cannot be charged if you replace it with a USB-C to USB-C cable. What do the lights on the charging case communicate? Charging case battery status: A flashing light means that the earbuds are being charged. Each light on the charging case equals 25% battery life of the charging case. When each 25% is reached, the corre- sponding light becomes stable, and the next starts flashing. When charged to 100%, all lights are lit. Earbuds battery status: How much battery life there is in the earbuds can be seen on devices like a smartphone. Check the top bar of your phone for a battery icon that appears when you connect your earbuds with it. I’m losing sound in one of the earbuds. What do I do? 1. Make sure the earbud has battery life. If not, place the earbud in the charging case to charge it. 2. Create a new Bluetooth connection between the earbuds and the earbuds and your device by placing the earbuds in the charging case and close the cap. Then, open the cap and pick out the earbuds again. How do I get started? 1. Make sure the earbuds are fully charged. Do this by charging the earbuds in the charging case until all 4 lights on the charging case are lit. How do I pair the earbuds? When you power them on for the first time they will auto-pair. You will hear ”earbuds paired” when this is done. This takes about one to two seconds after turning them on. How do I pair my device? 1. Take the earbuds out of the charging case or press the touch control area (below the “+” area) on both earbuds for about 3 seconds until you hear the starting sound. Either course of action turns the earbuds on. 2. Go to the Bluetooth settings on your device and make sure Bluetooth is turned on. 3. In the list of available devices, choose Defunc TRUE BASIC and accept to pair. What touch control commands are there? Power on: Open the cap of the charging case and take out the earbuds for auto-power on. If the earbuds are turned off and not in the charging case, press the touch control on both left and right earbuds for 3 seconds to power on. Power off: Put the earbuds back in the charging case and close the lid or touch either the right or left earbuds for 5 seconds. Auto-power off will be activated after 5 minutes in paired mode without connected device. Play/pause: While listening to music, double-click the touch area of any earbud to play and pause the music. Next: Press the right earbud for 2 seconds. Previous track: Press the left earbud for 2 seconds. Volume increase: Click once on the right earbud. Wait 1 second between each touch if you want to increase the volume. Volume decrease: Click once on the left earbud. Wait 1 second between each touch if you want to decrease the volume. Answer/end phone call: Double-click either the left or right earbud to answer or end the phone call. Reject call: Press either the left or right earbuds for 2 seconds to reject the call. Voice assistant: Triple-click on either earbud to activate the voice assistant on your device. How do I charge the earbuds? Put the earbuds in the charging case and close the cap. Make sure that the charging case has battery life. 23 4 BASIC

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: 2AKFED42B EST Technology Co., Ltd Report No. ESTE-R2309181 Page 3 of 3 3.
