Software Optimization:

1. Synchronize the latest version 3.1 firmware

2. New configuration interface, eliminating the need for repeated flashing, no need to buy a burner

3. Optimize power measurement calibration algorithm, power measurement is more accurate

4. Configuration interface description

- How to enter: Press and hold TUNE button and turn on the tail power switch at the same time. After OPTIONS is displayed on the screen, release the TUNE button to enter the setting interface.

- Operation mode: Short press TUNE button to change the current value. Long press the TUNE button to switch setting items.

- Description of each option:

Auto Mode (ON/OFF): Freely control the automatic mode of antenna tuner, and omit the automatic button, making it more convenient to use. If you plan to use the device without additional buttons, you can enable the automatic mode by setting the value to ON. The default value is ON.

Show Loss (ON/OFF): Freely control the loss calculation display interface, the display is more intuitive. Indicating the power delivered to the antenna and efficiency of fider and transmitter when input power is enough for correct SWR measuring.

Fider Loss (0.0-9.9): Freely define the loss value of wire, which can calculate antenna efficiency more accurately. This value uses for counting the power delivered to antenna. The loss value can be found in the reference data for the used cable or you can measure the exact value yourself.

Auto Delta (1.3-3.0): Customize the start value of SWR in automatic mode, autonomously control SWR adjustment range, and have a larger application range. The default value is 1.3. That is, when the automatic mode is activated, the tuning process will be triggered when the SWR is above 1.3 and when it changes to (1.3-1).

Display On (00s-95s): Customize the time when the screen is automatically turned off, which saves power when you are in standby

Set the time of glow display, in seconds. The backlight is glowing while press any buttons and if RF power comes to input. By default it is disabled, value 00.

Package Included:

-1 x Automatic Antenna Tuner

-1 x USB Cable

- 1 x User Manual

Note:

- The product is assembled and with shell.

- Due to its design, stable standing wave value cannot be measured when the power is lower than 10W, so the adjustment work cannot be guaranteed. QRP radio users please not purchase the product.
