# 3.2.4 Spraying Configurations
#### 3.2.4 Spraying Configurations
In this section, you can customize parameters related to spraying operations, including minimum and maximum PWM values, RC switch settings, and more.
To access the Spraying Configuration Section, navigate to RPA Settings, then select "Spraying Config." This action will display the following screen on your device.
**Steps for configurations**
**Step 1:** Activate the Spraying feature by choosing "Enable" from the dropdown menu. Then, configure the parameter values as described below.
Parameters:
Spraying Configuration:
* **Enable Spraying:** This option allows you to enable or disable the sprayer as needed.
* **RC Switch:** Set the value of the RC switch within the range of 0 to a maximum of 102.
* **BRD PWM Count:** This parameter controls the number of PWM-enabled Flight Management Unit (FMU) outputs. All unassigned pins on the board can be utilized for GPIO functions.
**Note**: This parameter is intended for advanced users and governs the number of FMU outputs configured for PWM. Any unassigned pins can alternatively be utilized for GPIO (General Purpose Input/Output) functions.
**SERVO9 Function \[Aux 1]**
* **PWM Min:** Minimum PWM pulse width in microseconds. Typically, the lower limit is 500, neutral is 1500, and the upper limit is 2000.
* **PWM Max:** Maximum PWM pulse width in microseconds. Typically, the lower limit is 800, neutral is 1500, and the upper limit is 2000.
**SERVO10 Function \[Aux 2]**
* **PWM Min:** Minimum PWM pulse width in microseconds. Typically, the lower limit is 500, neutral is 1500, and the upper limit is 2000.
* **PWM Max:** Maximum PWM pulse width in microseconds. Typically, the lower limit is 800, neutral is 1500, and the upper limit is 2000.
**Step 2:** After configuring the parameters to your requirements, click on the "Update" button to save and transmit the parameters to the device. You will receive a confirmation message, as illustrated in the following screen: "Parameter sent to the device."
