12. Avoid extreme temperatures as they can cause damage to the sensitive internal SD card.
13. Always perform a ground range check prior to your initial flight.
7.3 Pre-Flight Checks
1. Always verify the correct position of the switches, and the gimbals, prior turning ON your transmitter. Turn on the transmitter first, then receiver. JETI transmitters use “Model Checking”. This safety is designed so that the model memory stores the unique serial number of the receiver that has already been assigned to model. When the transmitter establishes communication with the receiver and the serial number does not match the number stored in the current model’s setup, the transmitter displays a warning. You will then be able to accept the change or reject the change. If you accept the change, the transmitter stores the new receiver number into the model’s setup and begins transmitting. If you reject the change, the transmitter will not communicate with the receiver and you will be allowed to select another model.
