Note the correct orientation of the data cable plug

The programmer will boot and display "ALZRC 3GYS Loading data!". After a successful connection the display 
will show "Load succeed!", and then displays the first menu "Basic setup".

9.2 Monitor

Use the "Monitor" menu to check the transmitter settings are correct.
When the screen shows "Basic setup", press the ENTER key to display "Monitor", and then press ENTER to 
select it.

The first page shows the 4 signal channels from the receiver
A: Aileron channel, E: Elevator channel, R: Rudder channel, C: Collective channel 
To check that the transmitter has all the mixing functions turned off, move each stick separately and check that 
only the corresponding channel changes and the remaining channels remain unchanged. 
Adjust all the transmitter channel directions, so for example, the rudder stick "R", shows "L" when the stick is 
moved to the left and "R" when moved to the right. Note that “U” (up) is stick up and not up elevator.
Position the throttle at mid stick and adjust all four channels on the monitor display so the value shows 0. This 
is done by using the transmitters internal fine-tuning (commonly known as Sub-trim). Look for the direction 
letter changing for absolute center.

When each of the sticks are moved to the limit (up, down, left and right), ensure that the value displayed 
shows 100. If not, adjust the corresponding channels end point adjustment (EPA) until it does read a value of 
100. Control sensitivity can be changed later with dual rates and expo.

Examples of stick travel where the value should read 100. Also note the "L", "R", "U" & "D".
Press the DOWN/DATA- key to select the second page, showing the transmitter channel gain signal and the 
gyro parameter set currently in use:

"G" indicates the transmitter gain channel value is displayed; "A" indicates tail lock gyro mode (heading hold); 
"N" indicated non locked gyro mode (rate); "Condition:" current gyro parameter set. For each gyro there are 
two sets of parameters to choose from. Here the value is just shown, and cannot be changed.
