List of Raw Materials:
1. PCB uses immersion gold circuit board, with UL certification.
2. Use PIC16F1454 (SOIC-14) and PIC16F18877 (TQFP-44) in a larger physical device.
3. All high-voltage capacitors are made of NPO materials, with a voltage resistance of 250V.
4. All magnetic rings use micron iron powder produced by German BASF6000, with super low loss and super low heat.
5. All relays use latching relays IM41GR for AXICOM, produced in Switzerland.
6. Built-in lithium battery 14500 (850mAh) x2.
7. BNC female connectors, 50 ohm, pure copper material.
8. Aluminum alloy shell.

Now it is Version 1.5:
New in FW version 1.4
1 - The button glitches solved
2 - More stability in bus transfer to OLED
3 - No continuous data transferring to the display

New in FW version 1.3
1 - Display memory feature for last SWR added
2 - full automatic mode error solved.

New in FW version 1.2
1 - Display memory feature for last SWR added
2 - full automatic mode error solved.

The Control Button has only 3 Functions:
- A short press resets the tuner and sets all relays to their initial state, in which all reactive elements are disabled and do not affect the signal flow through the tuner,
- A long press causes the tuner to enter the tuning mode
- A very long press for more than 5 seconds causes the firmware version to be displayed on the display.

Display:
The display mainly shows the current transmitter power and SWR in the transmitter cable and sometimes briefly indicates the modes.

Built-in Battery:
- The tuner is built on IM41 bistable relays, which means that a significant current is consumed by the tuner only for a short time during tuning; in rest mode, the tuner's relays retain their state for an arbitrarily long time, without consuming power.
- The built-in battery consists of two Li-Ion 14500 batteries connected in parallel. The best examples of these (for SANYO) have a capacity of 800 mAh each, the worst ones are usually 400 mAh.

Power Consumption:
- The tuner has 3 power consumption modes. In the operating mode, when the display indicates the parameters, lasts 5 minutes, after which the tuner falls asleep and the display turns off. You can wake it up with a short press on the button. After 30 minutes of sleep, the tuner turns off completely and you can turn it on by holding the button for a long time (more than 3 seconds).
- The current consumption in the operating mode is 12 mA, 170 μA in the sleep mode, and 37 μA in the off state.

Operating:
- Turn it on by holding the button for a long time (more than 5 seconds).
- Display indicates the parameters, lasts 5 minutes, after which the tuner falls asleep and the display turns off.
- You can wake it up with a short press on the button.
- After 30 minutes of sleep, the tuner turns off completely.

Package Included:
- 1 x Antenna Tuner
