9. Product Instructions
9.1. Electrode pad usage : gForceDuo TM has 2 sets of EMG cables, each set has 3 wires, the colors are red, green and yellow. The red one is the reference level output line, and the adjacent green and yellow lines correspond to the left and right EMG differential pairs. When in use, connect the disposable electrode sheets through the snap button at the end of the cable. The two electrode sheets of the same set of EMG sensors need to be adjacent to the user’s skin and placed in sequence along the direction of muscle contraction to be observed; the red button The connection line of the buckle is a reference level output, that is connected to the skin, such as areas above bones with relatively little muscle activity, through disposable electrode sheets.
9.2. Myoelectric raw data: The main purpose of gForceDuo TM is to monitor the contraction and force of muscles in two parts of the human body through two sets of differential pairs of myoelectric sensors. It is usually used to monitor two sets of muscles with opposite effects, such as the flexors and extensors of the forearm, and the biceps and triceps of the upper arm.
9.3. Power on: In the power off state, press the switch button of the gForceDuoTM . The device will start up after about 1 second, and the green indicator light below the button will light up. At this time, release the button, the vibration motor will vibrate, and initialization will begin; after the device is initialized, it will start waiting for Bluetooth to be established. Connect , the green indicator light flashes once per second (in rare cases, the green indicator light will flash slowly at a frequency of once every 4 seconds, which indicates that the initialization failed, then restart the device and re-initialize it. Yes); after the training game APP successfully connects to gForceDuoTM , the green indicator light stays on; when data or commands are transmitted, the green indicator light flashes quickly at a frequency of 2.5 times per second.
9.4. Turn on the phone and enter the firmware upgrade: In the power-off state, after continuously pressing the gForceDuoTM switch button for more than 10 seconds, the green indicator light flashes quickly 5 times, and then flashes slowly. At this time, the device enters firmware upgrade mode, and the Bluetooth name of the device changes to gForceDuo-BOOT. This operation should only be used if the device firmware is damaged or the device is seriously not working properly. Users can force the firmware upgrade of gForceDuoTM . After entering the firmware upgrade mode, upgrade the firmware through the gForce APP; if you give up the upgrade, you can perform the next shutdown operation, and gForceDuoTM will re-enter the working mode when it is turned on normally again.
9.5. Shut down: When the power is on, press and hold the switch button for more than 5 seconds and then let go, the green indicator light will go out (if the internal attitude sensor data is successfully automatically corrected after this power is on, the green indicator light will flash 3 times quickly to remind you) , gForceDuoTM power turns off automatically.
9.6. Charging: Charge the gForceDuoTM through the USB cable. While the device is charging, the red indicator led below the button lights up; when charging is complete, the indicator led turns green.

11. Precautions
11.1. Users need to perform appropriate warm-up and relax exercises before and after training to prevent muscle damage.
11.2. If you encounter a sudden increase in muscle tension during training, please stop training, stretch the muscles, and reduce the tension before continuing to train.
11.3. Training time and intensity should be determined according to individual conditions . Generally, training can be performed multiple times a day, as long as the patient does not feel tired after training. It is recommended to train 3 times each in the morning, noon and evening. The time of each training session is determined according to the patient’s tolerance, and they
