This guide is for Armor 80 Lite drone, EV800D goggle and LCD8202 FPV monitor.

Step 1: Determine the frequency to be used by your Armor 80 drone.

If you are taking part in a race, the Race Director will assign you the frequency. If you are racing with your friends, you can use the recommended "BEST IMD CHANNEL GROUP" to help you and your friend to determine the frequency for each drones. For example, you and 2 friends are racing. You and your friends can use 3 PILOTS IMD GROUPS where one use E2, you uses F4 and the other uses E6.

Explanation: IMD GROUPS are best practise of frequencies to minimize interference among the drones. Besides using IMD Groups to decide frequency, you should keep a distance between the flight area and pilot.
 

Step 2: Set the frequency on the Armor 80 Lite.

You are to use a thin screwdriver to press the frequency button on the drone.

For example, your drone is to use F4. You have to ensure the drone is at the "F" frequency group and then ensure the drone is at the "4" channel by:

• Press and hold the frequency button until the frequency group indicator LED jumps to change frequency group. Once the frequency group indicator LED jumped, let go. If the frequency group indicator LED is at the 4th LED, that means your drone is using "F" frequency group. Keep doing until the frequency group indicator is at the frequency group assigned to y our drone.
• Short press the frequency button until the channel indicator is at the channel assigned to your drone. 

Step 3: Set the goggle frequency to the same frequency assigned to the drone.

Always install the antenna before powering on the goggle. After power on the goggle, switch the goggle to frequency group using the Band+ button on the top of the goggle. See the screen of the goggle to ensure the goggle is at the frequency group assigned to to your drone. Once the goggle is at the frequency group, switch the channel of the goggle to the same channel of the drone using the "CH+" button on the top of the goggle. 

Step 4: Change the frequency of LCD to the frequency of the drone.

Always install the antenna before powering on the LCD. After power on the LCD, switch the goggle to frequency group using the Band+ button on the LCD. See the screen of the LCD to ensure the LCD is at the frequency group assigned to to your drone. Once the LCD is at the frequency group, switch the channel of the LCD to the same channel of the drone using the "CH+" button on the top of the LCD. Do note that Band "C" of LCD is Band  "E" of the LCD and Band "D" of the LCD is Band "F" of the LCD.
