6. Operating Instructions
6.1 General Charging
- USB Charging: Connect your devices to any of the 6 standard USB ports or the 2 PD/QC3.0 fast charging ports using appropriate USB cables. The display will show real-time charging parameters for each active port.
- Wireless Charging: Place your Qi-compatible device on the wireless charging pad located on top of the unit. Ensure the device is centered for optimal charging. The display will indicate wireless charging activity.

6.2 Display Overview and Navigation
The 1.8-inch color LCD screen provides comprehensive real-time data. You can easily switch between different display modes.

6.3 Adjustable Output Voltage (for Repair/Testing)
This feature allows precise voltage adjustment for powering and testing mobile phone components.
- Press the 'Confirm/Menu' key for 2 seconds to enter the current and voltage display option. A green box will appear on the display.
- Press the 'Confirm' button to select and modify the digits (tens, units, and decimal places) of the voltage.
- Use the 'Down' button to select the desired voltage value.
- Press the 'Confirm' button again to finalize the voltage setting.

6.4 Monitoring Current Curve
To view real-time current changes, which is useful for diagnosing device behavior:
- Press the 'Confirm/Menu' key for 2 seconds to enter the current curve diagram option.
- The device will display the current curve in real-time when a device is in a dynamic state (e.g., booting up or actively drawing power).
- An 'Arbitrary key Pause' function allows you to temporarily halt the curve display for closer inspection.
6.5 Backlight & Sleep Settings
Customize the display for comfort and power saving:
- Backlight Brightness: Double-press the up/down keys simultaneously for 1-2 seconds to enter backlight settings. Adjust the brightness level from 1-10. Double-press again to confirm.
