To keep your device from inadvertently becoming damaged, please follow these recommendations carefully: •Do not attempt to open any of the system components, as the electronic parts inside may become damaged. •Keep Twiins® devices in a dry place. Humidity, water ingress and condensation may damage electronic circuits and other parts. •Avoid exposing the device to extreme temperatures. Intense cold may create condensation inside the components as they warm up. Extreme heat may damage the battery, circuits, or body of the device and components. •Do not drop, hit, or bend the unit or components as the internal circuits may become damaged. •Do not paint or decorate Twiins® devices as the casings may become damaged or this may impede correct operation. •Do not use chemical products, solvents, or detergents to clean Twiins® devices as these may damage the devices. CE. FCC. Reach. RoHS. IPX5. EN BATTERY CARE AND MAINTENANCE 1.Charge properly: Use only the charging cable provided with this device with a USB Type-C| 5.0V 500mA charger approved by the manufacturer. Overcharging or using incompatible chargers can damage the battery. 2.Avoid extreme temperatures: Do not expose the device or its battery to temperatures outside the range 0-45 o C, such as extreme sunlight, heat, or freezing temperatures, as this may affect battery performance and lifespan. 3.Regular charging: For optimal battery performance, it is recommended to charge the battery regularly, even if not in use. Avoid fully discharging the battery whenever possible. 4.Unplug after charging: Once the battery is fully charged, unplug the charger from the device to prevent overcharging, which can reduce battery lifespan. 5.Proper storage: If storing the device for an extended period, charge every 6 months for the best battery maintenance and performance. Store in a cool, dry place. Avoid storing the device with a fully discharged battery. 6.Dispose of properly: Dispose of the device in accordance with local regulations and guidelines. Do not dispose of the device or battery in household waste; instead, recycle or dispose of them at designated collection points. 7.Safety precautions: In case of battery leakage, device overheating, or other abnormalities, discontinue use immediately and contact the manufacturer for assistance. Do not attempt to disassemble or repair the device yourself. Note Carefully: All batteries lose charging capacity over time. For the greatest possible battery life, it is important to: •Charge the battery fully before first use. •Allow the device to use most of its charge between charging cycles. •NOT operate the device during charging. •If storing for a long period, ensure the device is off and recharge every six months. Warning: Follow these instructions carefully to ensure safe and optimal battery performance. TROUBLESHOOTING Twiins® devices should give you years of trouble-free and reliable service. If you experience any issues, please check the product manual and www.twiins.com for detailed explanations, solutions and (online) tutorials.

The whole set is so small and lightweight you won’t notice it. Enjoy connectivity with any Bluetooth®/wireless connection enabled phone/device. Experience clear audio and comfort. Talk to a passenger by intercom. All without spoiling the look of your favourite helmet while you navigate the urban jungle. Twiins® Headset also works perfectly with the Twiins® Smart Button for push-to-talk communication on the Zello® walkie-talkie App. Available separately or in combined packs with Twiins® Headset. Charge your Twiins® Headset fully before first use. 1.Carefully lift the rubber USB cover on the side of the microphone unit, from the top as marked with an arrow. Do not detach. 2. Insert a USB-C charging cable and connect to a DC5.0V USB charger. 3.The indicator is red when charging and solid blue when charged. Full charge +/- 2hrs = 6hrs operation. Fast charge +/- 20mins adds 60mins. “Battery low” is heard and the LED flashes red when the battery is low, then repeats until empty. Phone also shows charge status. 4. Do not operate whilst charging. 5.If stored for long periods of time, charge every six months to keep the batteries in good condition. 6. The USB cover is a watertight seal. Close it by inserting the tab under the cover directly into the USB socket, whilst pushing the cover down and into the cavity until closed. RED - Charging BLUE - Full Flash RED - Low 3.6. Page 02 Charge your Twiins ® Headset 1 USB-C USB-A 5.0V Charger 1.2. EN 1.We recommend fitting the microphone on the left side of your helmet, with USB cover facing down. This better prevents ingress of water and dust. 2.Pass the microphone arm forward from the back of the helmet through or under the cheek-lining, so the microphone arm protrudes from the side of the helmet. 3.Attach a hooked pad to the back of each of the two headphones using the self-adhesive backing on those pads. Handle the headphones carefully by the sides, do not press their centres, as this may permanently damage sound quality. 4.Position the headphone of the microphone arm into the helmet at ear-height or in the speaker cavity of your helmet if it has one. 5.The hooked pad sticks to most helmet linings. If not, use the self-adhesive backing on one of the looped pads (supplied) and stick that into the helmet. Then attach the headphone with the hooked pad onto that looped pad. Additional looped pads are supplied to adjust the depth and comfort of the headphones. 6.Run the wire from the headphone on the microphone arm under the helmet lining and around the back. Then install the other headphone in the same way you just did the first. 7.Gently bend the microphone arm, so the microphone will point at your mouth. And that’s it! Removing the device: Carefully detach the headphones first by gently pulling them from the helmet lining and then slide the microphone arm backwards from the cheek lining. Do not pull out from the arm, as this will stress components. Fit Twiins ® Headset into helmet 2 Page 03 loop hook 234 6 7! EN Microphone •Twiins® Headset is unique because its microphone is neatly recessed into the device, covered with a fixed foam wind baffle, which can’t be lost. •There is no need to add any additional foam or wind baffle. •The microphone must face your mouth (with USB cover facing down), per the illustrations. 1.Press the button for 2 seconds to turn on. If an already paired phone is in range, the headset connects and flashes blue. If no paired phone is in range, it flashes red and blue, and searches for devices. “Pairing” is heard. 2. With the headset in pairing mode, select (on your phone): Settings  Wireless & Networks  Bluetooth® Turn on (Android) or Settings  Bluetooth® Turn on (IOS). 3. Select “Twiins Headset” from the list. 4. You will hear “pairing successful” on the headset. The LED will flash blue every 10 seconds, when paired. •To pair with a different device: Turn the headset off (press 2 seconds). Turn on again with a 5 second long press until the LED flashes red and blue. This forces the headset to enter pairing mode. Repeat steps 2-4. Pairing is only needed the first time devices connect. You may need to refresh the phone’s Bluetooth® list (or turn Bluetooth® on/off) for it to recognise the headset.
