Connect the KoolKey to the controller communication port (TTL/di port) using an interface cable.
Power up the controller using 120 V/230 V power supply.
Move the slider switch to required position and short press (1 sec) the start button to transfer data.
After successful data transfer, switch off the controller power supply and remove the KoolKey.

Note : While programming EET compact (EETc) and EKF controllers, KoolKey requires to be connected to a power source as mentioned in

Steps to program an unpowered controller (write function only):

Connect a Power bank or a 5 V power supply to KoolKey USB port.
Connect the Koolkey to the controller’s TTL/di port using an interface cable.
Write function gets initiated as soon as the KoolKey is connected to controller (no need to press the start button).
