The two straps are passed through the corresponding hole buckles, as shown in Figure 1.2. Then fold the strap back and tighten it, and stick the velcro tightly to complete the wearing. Fig. 1.1 Align knee with the central holeFig. 1.2 Strap passes through the hole buckleFig. 1.3 Stick the velcro tight 2. Battery removal Insert the battery cell into the battery bay facing up and forward as shown in Figure 2.1, and the indicator lights are red, green, and blue respectively, and the self-test indicates that the power-on is normal. Figure 2.2. Take the battery through the front hole to eject, as shown in Figure 2.3. Note: In the shutdown state, install the battery immediately after the battery is removed, and it may not enter the power on self-test. Because the main control board hardly consumes power in the shutdown state, there is still residual power in the capacitance of the main board. No self inspection will not affect normal use.

Multi-functional powerbutton In the shutdown state, press and hold the power key for 1.3 seconds to enter the standby state. The three-color power level indicator is on, and the power indicator is shown in Table 3.1. Standby mode Bluetooth function can be connected and operated. In standby mode, briefly press the power key to enter the shutdown state. During the treatment process

(see 4, 5, 6 and 7 for the treatment function), briefly press the power key to end the treatment and enter the standby mode. The treatment process can be started only in standby mode, except for vibration massage (see 7 for vibration massage function). Standby mode, automatic shutdown without operation for 1 minute.

Cooling treatment As shown in Figure 4.1, in standby mode, briefly press the refrigeration key to enter the cooling treatment course, and turn on 50% intensity vibration massage at the same time. Only a short press of the power key can interrupt and end the treatment. The course of treatment is divided into 6 steps, and the corresponding 6 Blue indicators flash respectively. The treatment time and temperature of each step are shown in table 4.1. Short press the vibration key to switch the vibration mode or turn off the vibration (see 7 for details).
