power adjustment
The output power of the machine in two stages: High-power file (1-1): >7W; Low power file (L): <IW
Turn off the power adapter, disconnect the transmitter power finish line state to follow these steps:
- First press and hold the power switch [ O,and connect the power (DC 12V) to the antenna, after 3 seconds after release the key, at this time into the power adjustment status, the LCD display shows “L” or “H” (default image file H high power)
- Press A) , and set it as high power (H)
- Press V), and set it as low power (L)
- Select the desired power profile, and press power setting finished, and it will into the frequency range setting state.
Frequency range setting
- After the power setting, it will enter the frequency range setting state, power setting is completed, press the LCD screen display shows a set of frequencies, the frequency data is the high-end of the operating band (below)
- For example, to set the operating frequency range of 9OMHz to 10OMHz, then through the key KA [V1 , adjust the frequency data as 100.00MHz
- Band after the completion of the high-end setting, press key [ <b] , the band will enter the low-end setting, LCD displayed data band low frequency (below), through key [ ] to adjust the data to 90.00MHz Then press key (O] ,at this time the setting finished.
