The T4PLS transmitter uses the telemetry type T-FHSS ("TFH") system.
It can also use the conventional FHSS and S-FHSS ("SFH") systems. Because the
R304SB receiver supplied with the T4PLS uses the telemetry type T-FHSS ("TFH") sys-
tem, 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 servos 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".
