Features:
Menu mode multi-selection: Quick double-click or long press for 3 seconds to turn on the device, adjust different functions by long pressing for another 3 seconds, enter the mode, and use the up and down arrow keys to adjust different functions. Each mode has a different interface and functionality. From left to right, the modes include voltage and hertz conversion mode, timer mode, forward and reverse mode, power disconnect and shutdown mode, and exit mode (switch between memory voltage modes, with 3 memory levels: M-1, M-2, M-3). Pressing the power button in the middle once represents the confirm button.
Clear screen display: OLED eye-care screen with suitable brightness that is not harsh on the eyes. Increase in voltage or hertz is displayed on the core screen by triggering the up/down buttons.
Charging module: Battery level dynamically displayed with graphical representation. Insert a USB cable for charging, and the screen mode will display that the battery is charging. To achieve better tattooing results, please use a professionally provided USB charging cable. The device can be quickly charged and has a 2000mAh dual replacement battery, ensuring that the battery does not run out during work.
Timekeeping: By switching to the timekeeping mode, you can enable or disable the timekeeping function. If the time mode is enabled, it can record 0-24 hours, with each record increasing by 1 minute. If you need to reset the time, you can enter the time mode, select clear, and restart the device.
Frequency/voltage: By long pressing the mode switch, the positions of the digital voltage and frequency display can be swapped. Depending on the preference of the tattoo artist, either hertz or voltage can be displayed as the primary parameter. The unit of 1 hertz is equivalent to 60 rotations per minute. For example, 100 hertz represents 6000 rotations per minute.
Voltage interval mode: Fine adjustment can be made by selecting the 0.1V increment mode, allowing for more accurate speed control through voltage adjustment.
Rotation and shutdown mode: The rotation mode is suitable for when creating shading effects. By using the forward and reverse rotation of the machine motor, combined with tattooing techniques and the angle of the skin, fine adjustments can be made to create fuller and more vibrant designs. In the shutdown mode, continuously long press until the shutdown symbol appears. Selecting OFF means exit, while selecting cancel means canceling the shutdown and continuing with operations. If there is no operation for 5 minutes after powering on, the device will automatically shut down.
