Before setting the Transmitter functions, check set the following items first.
Initial Set-Up
Preparations (Transmitter)
(Display when power switch turned on)
When the power switch is turned on, the currently selected model number is displayed.
Check if this number is the model number you want to set-up. To change the model
number, use the Model Select function.
(HOME screen)
Turn on the transmitter power.
The model number is
displayed.
The battery voltage is
displayed.
Receiver Type Check (RX MODE)
This mode sets the RX type of the transmitter to match the receiver and servos used.
The T4GRS transmitter uses the telemetry type T-FHSS ("TFH") system.
It can also use the conventional FHSS and S-FHSS ("SFH") systems. Because the
R304SB(-E) receiver supplied with the T4GRS uses the telemetry type T-FHSS ("TFH")
system, its RX type must be set to the T-FHSS high speed mode ("TFH-HI") or the T-
FHSS normal mode ("TFH-NR"). Never use analog servos when the RX type was set to
the T-FHSS ("TFH") 2.4GHZ system high speed mode "TFH-HI" or the S-FHSS (SFH)
high speed mode "SFH-HI". The servos may be damaged. For example, if analog ser-
vos are used with a telemetry type T-FHSS receiver (R304SB, etc.), the RX type must
be set to "TFH-NR", and if analog servos are used with an S-FHSS receiver (R2104GF,
R204FG-E, etc.), the RX type must be set to S-FHSS ("SFH-NR") system normal mode
or FHSS ("FHSS") system. When using digital servos (including BLS Series brushless
servos), any RX type can be used.
When a dedicated FHSS receiver (R603GF/R2004GF) is used, it will not operate if the
RX type is not set to "FHSS".
