CPS Mixing "CPS MIX" This function controls the Futaba CPS-1 channel power switch. Normally, when using the CPS-1 unit to power the vehicle lights etc (LED) the CPS- 1 unit with LED connected is connected to a vacant switch channel and the LEDs are turned on and off by the switch while the vehicle is running.

Throttle Mode "TH MODE" (Throttle system) This menu has the following 4 functions: - Servo neutral mode, which sets the throttle neutral ratio to 7:3 or 5:5 - Idle up, which raises the idling speed when starting the engine to improve engine start- ing performance of a gasoline car (boat) - Neutral brake, which applies the brakes at the neutral position of the throttle stick - Throttle off (engine cut), which stops the engine of a boat, etc.
However, considering safety, and to prevent the motor from rotating instantly when the power was turned on, the MC950CR, MC851C, MC602C, MC402CR, and other Futaba MC (Motor Controllers) will not enter the operation mode if the neutral position is not confirmed.
However, when using the MC950CR, MC851C, MC602C, MC402CR, or other Futaba MC (Motor Controller), confirm that the MC is in the neutral position and the set is in the operation mode before setting the neutral brake function switch to ON, the same as the idle up function.

Throttle Off (engine cut) "THOFF" This is a function select switch dial function. The throttle off function ON/OFF switch must be set. The engine cut function stops the engine of a boat, etc. by operating the throttle servo to the slow side by switch regardless of the position of the throttle stick and the setting of other functions (reverse function setting is effective).

"MIn" which sets the frequency when the load is small, is set to the high frequency side (large value) when extension is desired after straight- aways and curves. "MAX" which sets the frequency when the load is large, is set to the high frequency side (large value) when you want to suppress the rise from low speed and when motor heating and commutator roughness are sensed.

Page1 TBM-(TURBO MODE) OFF /LV1 /LV2 Same as Link software Turbo Mode This function sets the turbo mode. More power can be enabled using the turbo mode. Depcompleted on the setting, the motor and ESC may be damaged so use this setting carefully. (Note) When LAU (LEAD ANGLE USE) is off, lead angle setting will not operate even if set to LEV1 or LEV2.
Page 14
LAU-(LEAD ANGLE USE) ON /OFF Same as Link software Lead Angle Use This function is effective when TBM (Turbo Mode) is LEV1 or LEV2 and sets whether or not lead angle is used. This setting has priority over the TURBO MODE setting. When using in races in which the lead angle func- tion is inhibited by the ESC set this function to OFF.

Data Transfer "MDL TRANS" This function copies the model memory data of one T4GRS to another T4GRS. Con- nect the communication port of both T4GRS together with the optional DSC cord for T4PK. Use this function with the T4GRS power switch set to the display side. Note: If the T4GRS battery voltage drops, the display switches to low battery display.
