HPI Racing TF-20, TF-21 Instruction Manual

HPI 2.4GHz Digital Proportional Radio System Instruction manual

●INTRODUCTION

・Automatically in search of the empty band of 2.4G, a transmitter sets up a band.

Therefore, the conventional crystal change is unnecessary.

・A transmitter has original different ID.

Therefore, a receiver malfunctions with neither other same transmitters nor the transmitter
of other 2.4G.

・Since high-speed digitization of all the dynamic-control signals is carried out,

when a wave is lost, the fail-safe-system function operates and a car stops safely.
Also when the Battery capacity of a receiver is lost, the fail-safe-system function operates.
