Function description:
- When the machine is on, press the Down key for a short time to turn on or off the buzzer alarm. Press the Down key for 3 seconds to enter the high standing wave alarm point setting interface (default 2.0). Tap the Down key to lower the alarm point (minimum 1.5), and tap the UP key to raise the alarm point (maximum 5.0). Tap the M key to save and exit the standing wave point setting.

- Press and hold down the Down key to turn on the machine in the shutdown state, enter the power fine-tuning interface, tap the Down key to reduce the meter display power in 1% steps, tap the UP key to increase the meter display power in 1% steps, (the default is 0, which can be adjusted between - 20% and+20%), and press the M key to save and exit.

- Press the UP key for a short time to switch between Chinese and English in the power-on state. Press the UP key for a long time to enter the delayed power-off setting interface (automatic power-off without transmitting for 10 minutes by default). Tap the Down key to reduce the delayed power-off time (at least 2 minutes), tap the UP key to increase the delayed power-off time (at most 98 minutes, if it is set to 99 minutes, the delayed power-off function will be turned off), and tap the M key to save and exit the standing wave point setting.

- Press and hold the UP key to turn on the machine in the shutdown state to enter the standing wave fine-tuning interface. Tap the Down key to reduce the standing wave of the meter according to 1% step, tap the UP key to increase the standing wave of the meter according to 1% step, (the default is 0, which can be adjusted between - 20% and+20%), and press the M key to save and exit.

- Tap the M key to switch the display interface in the state of power-on, and press and hold the M key for 3 seconds to turn off the software (long press and hold in the state of charging is invalid).

- The indicator light turns red when it is charging and turns green when it is full charged.

- If the power is turned on and not charged, the green indicator light will turn on when the standing wave is less than 1.5, the yellow indicator light will turn on when the standing wave is between 1.5 and 2.5 and the red indicator light will turn on when the standing wave is more than 2.5.

- For the battery voltage is lower than 3.4V when the battery is not charged: If the buzzer is turned on, the buzzer will alarm and the yellow indicator will light up. Please connect the charger. If the battery is not turned off and the charger is not connected, the battery will automatically turn off when the battery continues to drop to 3.35V. After connecting the charger, the battery will automatically turn on. If the battery is not used for a long time and the battery voltage is particularly low, the LCD screen may display garbled code, please turn off the rear power switch and charge it for 1 hour before turning on the switch to display normally.

- The standing wave meter has a soft switch and a hard switch. It can be used frequently without moving the switch. It will automatically shut down and turn on automatically when transmitting. It is recommended to turn off the hard switch behind if it is not used for a long time to avoid over-discharge of the battery. And it is recommended to charge once every half a year. When turning off the hard switch, connect the charger and it will automatically charge, but there is no status indication. (The hard switch will only turn off the system power supply and will not affect the battery charging. If the hard switch is turned off, the soft switch will certainly have no effect.)
