This manual contains instructions for safely replacing a transmitter

hobby product. The instructions require basic technical knowledge and
mechanical skill. The replacement should not be attempted by children or
beginner hobbyists.
Do not attempt disassembly, use with incompatible components, or
augment the product in any way, outside of these instructions. Failure to
follow each instruction and precaution could result in a break of signal
