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 CPS1 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. However, when the CPS1 mixing (CPS MIX) function is used, the LED can be turned on and off and flashed in
step with steering and throttle operation, as well as being turned on and off by switch.
The flashing speed (cycle) can also be set.
For instance, the LED can be flashed as a brake light when the brakes are operated.
Setting Special mixings
When the 4th CH was set to ACT at Brake Mixing or when Dual ESC Mixing is used,
CPS mixing cannot be used.

Idle-Up "IDLUP"
This is a function select switch dial function. The idle up switch must be set.
This function is used to improve engine starting performance by raising the idling speed
when starting the engine of a gasoline car (boat). It is also effective when you want to
eliminate any braking effect when the power is turned off during running, due to the
effect of your gear ratio setting and choice of motor when operating an electric car.
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. When using the MC950CR, MC851C, MC602C, MC402CR, or other Futaba
MC, confirm that the MC is in the neutral position and the set is in the operation mode
before setting the idle up function switch to ON.
Operation
The throttle neutral position is offset to the forward side. There is no linkage locking,
etc. because there is no change near the maximum operation angle even when the neutral position is offset by this function.
Operation Display
While this function is ON, the LED blinks.

Neutral Brake "NTBRK"
*This function is not available in "TH-STK : F10 mode".
This is a function select switch dial function. The neutral brake function ON/OFF
switch must be set.
The neutral brake, which applies the brakes at the neutral position of the throttle stick,
can be set. 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. In addition, when the idle up function or throttle off
function is set, these functions have a higher priority than the neutral brake function.
Reference
The ESC neutral brake function and T4GRS neutral brake function can be used simultaneously. However, when setting is difficult to understand, we recommend that only
one neutral brake function be used.
Dial / Trim Setting
When the neutral brake function is "ON", the neutral brake rate adjustment is automatically assigned to the throttle trim (DT1/2/3/4 or DL1).

ESC Link Function "MC LINK"
This is a special function which lets you set the contents of the Link software in
Futaba speed controller (ESC), MC960CR, MC940CR, MC950CR, MC851C,
MC602C, MC402CR, etc, with variable frequency and other data changes at the
T4GRS transmitter. However, some data changes require a PC and Link software.
This function is used by connecting ESC directly to the transmitter. The T4GRS
power switch is set to the display side. Use the various optional servo extension
cords according to the distance between the transmitter and ESC. The last data read
from ESC to T4GRS or the last data written from T4GRS to ESC is saved to the
T4GRS. Since the data for each model memory can be saved, the data of up to 40
models can be saved.
-When the T4GRS battery voltage drops, the display switches to low battery display. Therefore, use this function when there
is ample battery capacity remaining.
-Also connect the battery at the ESC side.
-Note: Do not read to the T4GRS an MC940/960CR whose speed was set to over 99990rpm by Link software side Boost
Angle rpm setting.

MIn-(PWM FREC MIN LD) 100Hz~10000Hz (10kHz)
MC950CR:500Hz~30000Hz (30kHz)
Same as Link software PWM frequency (at Min. load),
MIn sets the "0"A PWM frequency at minimum load.
MAX-(PWM FREC MAX LD) 100Hz~10000Hz (10kHz)
MC950CR:500Hz~30000Hz (30kHz)
Same as Link software PWM frequency (at Max. load).
MAX sets the PWM frequency at maximum load at the output current limit value set by Current Limiter.
BRK-(PWM FREC BRK LD) nOR(2000Hz)/ HIG(1000Hz)/ SPH(500Hz)
MC950CR:500Hz~30000Hz (30kHz)
Same as Link software Brake PWM at frequency.
This setting can set the brake PWM frequency.
nTB-(NEUTRAL BRAKE) 0%(OFF)~100%
Function
Same as Link software Neutral Brake.
Use this setting when you want to use the brakes at the neutral throttle (OFF) position by throttle operation. The
larger this value, the greater the braking force. When you want to use the neutral brake, set this value to "0%".
CLM-(CURRENT LIMIT) 50A~300A (MC950CR:50A~300A), OFF Same as Link software Current Limiter.
Current Limiter sets the current value at maximum load here.
Since setting of the MAX is based on the output current limit value set by Current Limiter, Current Limiter does not
have to be turned OFF except when a current exceeding 300A is generated.
"MIn" which sets the frequency when the load is small, is set to the high frequency side (large value) when extension is desired after straightaway 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.
When the rise from low speed is poor, and becomes bad even when "MAX" is set to the low frequency side, use the log data to check if there
was a momentary voltage drop. When you want to suppress the overall power, lengthen the run time, and otherwise improve efficiency, set
both "MAX" and "MIn" to the high frequency side. When you want to set a fixed PWM frequency at full range regardless of the load current,
set PWM frequency (at Max. load) and PWM frequency (at Min. load) to the same value.

LBP-(LOW BATTERY VOLT) 2.5V~6V
DBA-(DEAD BAND) ±2μs~±50μs
2.5V~7.5V for MC950CR
Same as Link software Dead Band.
This sets the range (neutral point range) over which the
ESC does not respond to transmitter throttle operation.
The larger the set value, the wider this range.
Same as Link software Low Bat Protection
This setting cuts off the output to the motor when
the main battery voltage drops to the set voltage.
This stops the receiver ceasing operation when the
power to the receiver becomes insufficient whilst
running due to a drop in the power supply voltage.
When the power supply voltage recovers, power is
supplied to the motor once more.

CTM-(C.L. TIME LIMIT) 50A~300A /CLT-(C.L. TIMER) 0sec(OFF)~240sec
(except MC950CR)
Same as Link software Current Limiter (Time Limit)/Current Limit timer.
The output current can be limited up to a set time from the start of running.
This is effective in preventing the motor from outputting wasted energy when
the voltage is high immediately after the power battery was recharged.
- "CTM" (Time Limit) sets the maximum output current for the time the output
current is limited.
- "CLT" sets the time the output current is limited. This function is disabled
when set to "0" sec.
Since the Current Limit Timer starts when the throttle stick is pushed forward
and current is output to the motor, this function begins to operate when the
motor is run during trim adjustment, etc.

The LA-(LEAD ANGLE) and A, B, C, D, E BA- (A, B, C, D, E BOOST ANGLE) relationship is shown on
the graphs below. Graph [A] shows the relationship when the same value is set at points A, B, C, D, E BA(A, B, C, D, E BOOST ANGLE) of [A] and [B] and the LA-(LEAD ANGLE) was set to "0" and graph [B]
shows the relationship when a value other than "0" was set at LA-(LEAD ANGLE).
As shown in the graphs, [B] is added to the A, B, C, D, E BA-(A, B, C, D, E BOOST ANGLE) set lead angle and [A] is added to the LA-(LEAD ANGLE) set lead angle. For example, if "3" is set at ABA and LA of [B]
is set to "2", the actual ABA becomes 3+2=5 (deg). Since LA of [A] is "0", the actual ABA also becomes
3+0=3 (deg).

This function copies the model memory data of one T4GRS to another T4GRS. Connect 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.
Therefore, use this function when there is ample battery capacity remaining.
Note: Since the receiving side writes the new contents of the currently selected model
memory, always check the model number before executing this function.
Data is not interchangeable with another type of transmitter.

Telemetry "TELEMETRY"
With the telemetry system, the running status can be displayed at the transmitter and
also recorded as a data log by mounting various sensor units to the chassis.
The telemetry related screens are only displayed when the T4GRS power switch is in the
PWR ON position. When the power switch is in the DISP position, the telemetry related
screens are not displayed.
(HOME screen)
The T4GRS displays four kinds of information on the HOME screen;
receiver power source (battery) voltage, external power supply (drive battery) voltage, speed, and temperature.
*The telemetry function is compatible with only the T-FHSS system.
*The telemetry function requires a corresponding receiver (R304SB,R304SB-E).
*Only T4GRS with R304SB(-E) ID registered have a telemetry display.
*Multiple sensors of the same type cannot be used.
The sensor data can be checked at the transmitter by connecting
the telemetry sensor sold separately to the S.BUS2 connector of
the R304SB(-E) receiver.
Telemetry info
The figure is an example of connection of a telemetry sensor. The data of up to the following 3 types of sensors and the receiver power supply voltage can be transmitted by
using the 3-way extension cord or double extension cord sold separately.
The receiver power supply can also be connected to the S-BUS2 connector or each of
CH1-4. A receiver power supply voltage sensor is unnecessary.
*The S-BUS2 system exerts control by connecting multiple gyros, servos and other devices corresponding to one S-BUS2
connector. Each device is separately controlled by setting the channel No. or slot No. individually for each device.
A slot No. is also set for telemetry sensors. With the T4GRS system, each slot No. of a telemetry sensor must be set to its initial value. Since the slot No. can be changed for other aircraft type transmitters (T18MZ, etc.), sensors with changed slot No.
will not operate if not returned to their initial slot No. When using a sensor that is used with transmitters other than a T4GRS,
whether or not the slot No. is set to the initial value given in the sensor instruction manual must be checked at the changed
transmitter (T18MZ, etc.). With the T4GRS, the set slot No. cannot be checked or changed. So, essentially, if a sensor has
been used in an 18MZ, and you want to use the same sensor with your T4GRS, you must first change the slot number through
the 18MZ or it will not work in your T4GRS.

Log Setting Start/Stop
The data from a telemetry sensor can be saved to the T4GRS as a data log. Since the
data is sequentially updated, when data logging is performed, the old data is erased.
Only 1 data is saved.
The interval at which the data is acquired can be selected from a minimum 0.1 second
to a maximum 60 seconds. Because the maximum count is 200, if the count is made 200
counts at 0.1 second intervals, 20 seconds worth of data is acquired, and if the count is
made 200 counts at 60 second intervals, 3 hours 20 minutes worth of data is acquired.
Data logging is started and stopped by setting SW1 set by SW/Dial function to "LOGGER" and by switch (SW1). If the switch (SW1) is not set, data logging is started by
throttle stick from the log setting screen.
Data logging can also be started by throttle stick from this screen and stopped by switch
