6. Setup

6.1. Initial Charging

Upon receiving the product, charge it for at least 20 minutes to activate the internal lithium battery. Connect the provided USB-C cable to the Type-C charging port on the device and plug the other end into a compatible USB power adapter (not included).

6.2. Connecting External Devices

• Audio Output: To hear the generated frequencies (if audible), connect headphones or external speakers to the 3.5mm audio output jack on the left side of the device.
• External Signal Output: For scientific experiments or connecting to other electronic equipment, use the multi-colored output wires from the Signal Output Interface. Refer to the specific requirements of your external equipment for proper connection.

7. Operation

7.1. Power On/Off

Long press the Power Button (bottom left) for approximately 3 seconds to turn the device on or off. The 1.8-inch TFT display will illuminate upon power-on.

7.2. Setting Frequency

1. Use the Numerical Keypad (0-9) to input your desired frequency in Hertz (Hz). The display will show "Input (Hz):" as you type.
2. After entering the frequency, press the Check Mark Button to confirm. The device will then output the selected frequency.

7.3. Changing Waveform

Press the Waveform Switching Button (top right of keypad) to cycle through different waveform types. The current waveform will be displayed on the screen (e.g., SQU for square, TRI for triangle, SIN for sine).

7.4. Setting Timed Shutdown

Press the Timed Shutdown Button (second from top right) repeatedly to set the desired shutdown duration from 1 to 24 hours, or to select "Normally-on" for continuous operation. The selected time will be displayed as "Shutdown after XX H".

7.5. Adjusting Brightness

• Screen Brightness: Press the Screen Brightness Button (third from top right) to adjust the display brightness from 01 to 10 levels.
• Signal LED Brightness: Press the Signal LED Brightness Button (bottom right of keypad) to adjust the brightness of the signal indicator LED from 00 to 09 levels.

7.6. Starting/Stopping Signal Output

While in the output state, pressing the Check Mark Button can start or stop the signal output. This allows for quick toggling of the generated frequency.

7.7. Saving Parameters

The device is designed to save your last used settings. When you power off the device, the current frequency, waveform, and timer settings will be retained for your next use.
