4. The instructions below give instructions on how to properly use the RADIOMASTER 4-in-1 Module.

RADIOMASTER 4-in-1 Module Setup:

The 4-in-1 module is very easy to set up and use by anyone, including new users. The following is a step-by-step tutorial for installing and setting up the module on your transmitter.

a) Step 1 - Select The Correct Size Module:

If your transmitter has a JR sized module bay then select the Micro/JR version. If your transmitter has a Nano sized module bay, select the Nano size module.

b) Step 2 - Inserting The Module:

To insert the module into the transmitter simply slide the module into the module bay until it locks securely into place.

c) Step 3 - Select MULTI OR Multi-Protocol Mode:

On the transmitter (for example - OpenTX or EdgeTX) go to Model Setup then scroll to External Module and select the correct setting, MULTI or Multi-Protocol.

d) Step 4 - Choose The Protocol You Want To Bind To:

The protocol you select will be determined by the manufacturer of your receiver (e.g.- FrSky D8, DSMX, FlySky AFHDS, etc.).

e) Step 5 - Bind To Your Receiver:

Turn on your receiver in bind mode and press "Bind" on your transmitter. Wait until the LED light on your receiver indicates that binding was successful.

f) Step 6 - Perform A Range Test:

Before you attempt to fly or drive your model, always test the following:

The signal strength, the positioning of your antennas, and how your model responds to the controls.

g) Step 7 - Flying Your Model:

Once you have bound the model to your receiver, your model should be ready to use.

h) Step 8 - Check For Updates:

Periodically check for updates to your firmware. By updating your firmware you will gain access to additional protocols and improve the performance of your module.

Single Protocol Module	4-in-1 Module
Works with only one receiver brand	Works with 60+ protocols
Limited flexibility	Unlimited model compatibility
More expensive long-term	Cost-effective
Less convenient	Very convenient
Requires multiple transmitters	One radio for everything

This makes the RADIOMASTER module an essential upgrade for any serious RC pilot.

8. Recommendations for Safe Usage of the Module:

To help ensure the module's safe operation:

a) The operator must perform a test range prior to all flights,
