While charging, the LED will shine red. The LED will turn off when charging is complete. Download Freedrum Studio While your sensors are charging, download the Freedrum Studio app. Attaching your pedal sensors to your legs Once your sensors are fully charged, take the circular ones and attach them to your legs. The best position is just above your knee. Ensure the (L) icon is on your left leg and the (R) icon is on your right leg. The icons should be on the insides of your legs like shown in the image. It's also important that the pedals are facing upwards like in the picture shown. 4 Rev. 10/03/2023 Freedrum Electronic Drumsticks Manual Turning on your sensors Once your sensors are attached to your knees, you can turn them on by pressing the large circular area once. You can turn on your drumsticks by pressing the button located within the oval ring once. 5 Rev. 10/03/2023 Freedrum Electronic Drumsticks Manual Connecting to your device You connect your Freedrum using the Freedrum Studio app. There are two ways to connect Freedrum to your device: 1. In the device connection menu on startup, select "Freedrum". 2.If you have already used the app before and you see a drum kit (this is the tab called "Free Play"), you can connect by tapping the circular button on the bottom-right. You should see "Freedrum" appear in the list. Press "Freedrum" to connect and tap continue. With the Freedrum Electronic Drumsticks, you'll only need to connect to one Bluetooth device, which is different from the Original Freedrum that required connecting to four separate devices. 6 Rev. 10/03/2023 Freedrum Electronic Drumsticks Manual Calibrating your drumsticks When you begin playing Freedrum, you must calibrate your drumsticks. This is done to place the drum kit in the correct direction. Calibrate your drumsticks by pointing both of them directly in front of you and pressing each of the buttons once at the same time. If the calibration is successful, the right stick should shine blue and the left stick should shine red. Repeat the process if they do not shine blue and red. Positioning Keep the area around you clear of any obstacles and position yourself at least one meter away from any walls or flat surfaces. Make sure you keep your back straight and your legs in a 90° angle when lifting up your heels 7 Rev. 10/03/2023 Freedrum Electronic Drumsticks Manual Using your drumsticks Play the drumsticks above your knees. Avoid playing drums below the height of your knees. The drumsticks should always be kept above the pedal sensors. Avoid hitting the drumsticks together. If you accidentally hit the drumsticks together, keep both sticks still for one second. Avoid playing with excessive movement. This means that you need to pay attention to your playing technique and develop a good sense of control. Using your pedal sensors Ensure your pedals sensors are positioned correctly by following the previous steps on attaching your pedal sensors to your legs. Your right leg is set as a kick drum and the left leg is set as the hi-hat. To play the kick drum, lift your right heel above the ground and then tap it back on the floor again. If you tap harder the velocity of the drum sound will increase. To open the hi-hat, lift your left heel above the ground and play the hi hat cymbal with your stick. You can close the hi-hat by tapping your heel back on the ground. 8 Rev. 10/03/2023 Freedrum Electronic Drumsticks Manual How to Play Freedrum Electronic Drumsticks Calibrating When you start using Freedrum Electronic Drumsticks, it's important to calibrate your drumsticks so that the drum kit responds correctly to your movements. To calibrate, simply point both drumsticks directly in front of you and press both buttons at the same time. If the calibration is successful, the right stick will light up blue and the left stick will light up red. If this doesn't happen, try calibrating again until the sticks shine blue and red. 9 Rev. 10/03/2023 Freedrum Electronic Drumsticks Manual Playing Style When you start playing with Freedrum Electronic Drumsticks, it's important to learn the correct playing styles to make the most out of your kit. It might take some practice to get comfortable with this playing style, so don't rush it! To create the right sound, use your wrists and underarms to hit the drums. Avoid using too much force or whipping the sticks around. It's important to keep your drumsticks in the same position when playing the same drum with both hands. Also, try to avoid sticking your elbows out too far as this can cause you to hit the wrong drums. You can experiment with different hand and arm positions to find a comfortable playing style that works for you. Have fun exploring and finding your own unique drumming technique! Finally, using your whole arm and too much force can cause the drumsticks to play the wrong sounds and lose their calibration, so make sure to focus on using the correct playing style. 10 Rev…

ESB Antenna

INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a Electronic drumsticks with ESB function operating in 2428-2472MHz. The EUT is powered by DC 3.7V by rechargeable battery or charged by DC 5V through adapter. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna Modulation Type: GFSK Antenna Gain: 0dBi The nominal conducted output power specified: -4.5 dBm (±5dB) The nominal radiated output power (e.i.r.p) specified: -4.5 dBm (±5dB) According to the KDB 447498: The Maximum peak radiated emission for the EUT is 94.1 dBμV/m at 3m in the frequency 2428MHz The EIRP = [(FS*D) ^2 / 30] mW = -1.13dBm which is within the production variation. The Minimum peak radiated emission for the EUT is 85.9 dBμV/m at 3m in the frequency 2472MHz The EIRP = [(FS*D) ^2 / 30] mW = -9.33dBm which is within the production variation. The maximum conducted output power specified is 0.5dBm= 1.122mW The SAR Exclusion Threshold Level: 푃 th (mW) = ERP 20cm * (푑/20cm) 푥 (X= ) = 3060 * (0.5/20) 1.9 mW = 2.72 mW Since max. conducted output power and effective radiated power (ERP) is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. Note: EIRP is higher than ERP, thus EIRP is compared with the Exclusion Threshold. FCC ID: 2A7YE-FD2DS
