Tuning

1.First,please connect the radio and antenna respectively.
2.The radio station is set to the frequency range supported by the device, the minimum output power, and
the working mode is FM, AM, CW or SSB.
3.Long press the [TUNE] button to achieve tuning or give up tuning, or when the swr exceeds the set value
when operating the radio, automatic tuning will also be triggered.
4.Operate the radio station to keep transmitting, at this time, the device will automatically tune to the
lowest standing wave and then stop automatically.
5.When the screen shows [SWR] value is 1.0-2.0, the tuning is successful.
6.Set the radio power to the maximum transmission power, frequency, and mode supported by the device
to make a call.

Notice

1. Antenna feeder system: A good antenna feeder system can improve the tuning success rate and avoid
abnormalities during normal power transmission after tuning;
2. Power supply instructions: Ensure that the device has sufficient power. It is recommended that the
battery voltage is not lower than 3.6V. If the voltage is too low, the device will restart or shut down;
3. Radio type: The factory default radio type is 100W, in order to bring you good power accuracy and
functional experience, please adjust according to the maximum output power of your radio [FIX RADIO];
4. Equipment calibration: The power and standing wave value algorithm of the tuner has been calibrated
when the tuner leaves the factory. But in order to ensure the accuracy, please recalibrate the [FIX PWR] and
[FIX SWR] parameters after changing the use environment, antenna feeder, and radio. Please refer to the
station.
5. Start tuning: Please fully confirm the transmission power, frequency, and mode of your radio before
starting to tune, so as not to damage the equipment.
6. Communication operation: During the normal communication process, please always pay attention to
the standing wave and power of your radio station. If there is any abnormality, please stop transmitting in
time and check before operating.
