Introduction
Setting mode of TACHYON (amplifier)(Refer to P.10 of “TACHYON Instruction Manual”)

TACHYON is equipped with two kinds of memory area. The preset
value by TAO uses the memory at the [Program Card Mode].
Since the setting of the TACHYON main body is saved in the [ESC
Mode], mutual interference is eliminated.

About the ProductThank you for purchasing “TAO”, a dedicated effector for thebrushless system. The ACUVANCE brushless systemdemonstrates a synergistic effect when used with TACHYON(brushless amplifier), LUXON (brushless motor), and TAO(effector). Each frequency of drive (advance), neutral brake, andbrake, which determines the characteristics of the amplifier, canbe set separately, and the output characteristics can be changed
individually as well. Also with LUXON’s angle adjustment function,
the motor’s characteristics can be changed. (Refer to P.8) Thesesettings can be saved up to three patterns and easily confirmedby the liquid crystal display with backlights. In this way, settings
can be changed during operation to achieve comfortable drivingthat satisfies your driving desires. Please enjoy the sophisticatedbrushless system.
CAUTIONTAO is a dedicated effector for our company’s products, “TACHYON”
and “LUXON”. It is not compatible to any competitor’s brushless
products. Note that we will not be responsible for any damage whicharises by using TAO with competitor’s product, as well as repairs.
