Switchingthecommunicationmode
This radio is equipped with an Automatic Mode Select (AMS) function which 
automatically selects any one of four communication modes to match the signal 
received.
Besides C4FM digital signals, analog signals are also identified in order to automatically 
match the communication mode of the partner station.
* Digital communication can be performed only on the Band A.
Press   to display “

Basic Operations
Receiving
When operating in a fixed communication mode, switch to the communication mode using 
.
The communication mode will switch in sequence as follows each time   is pressed.
“
▀
○○ (AMS)” → “DN (V/D mode)” → “VW/DW (FR mode)” → “FM (Analog)”
Operatingmode Display Explanationofmodes
AMS
(Automatic Mode Select)
▀
○○ The operating mode is automatically selected from four communication 
modes to match the signal received.
(The ○○ part display differs according to the signal received)
The AMS feature settings may be changed via Set-up Menu
 (  P.174).
V/D mode
(simultaneous voice and data 
communication mode)
DN As the audio signal error is detected and repaired at the same time as 
the transmission of the digital audio signal, it becomes more difficult 
for conversations to be cut off. A basic digital mode of C4FM FDMA.
Voice FR mode
(Voice full-rate mode)
VW Digital voice data is transmitted using the entire 12.5 kHz bandwidth. 
High quality voice communication is possible.
Data FR mode
(high speed data 
communication mode)
DW High speed data communication mode using the entire 12.5 kHz 
bandwidth for data communication.
Automatically switches to this mode for video communication.
Analog FM mode FM Analog communication mode using the FM mode.
This mode is effective for communication when the signal strength is 
so weak that the voice is cut off midway in the digital mode.
Caution
In the V/D mode (“DN” displayed), the position information is included in the transmitted signal during 
the conversation, but in the Voice FR mode (“VW” displayed), the position information is not included.
Switchingthemodulationmode
The modulation mode can be selected from “FM”, “NARROW FM” and “AM” in the analog 
mode.
When shipped from the factory, the mode is set to “AUTO” where the most optimal 
modulation mode is automatically selected according to the frequency.
1  Choose the operating band
2 Press   for one second or longer
  The set-up menu will be displayed.

  The red bar and PO meter level will disappear and 
the radio will return to the receiving state.
Tips
•  Refrain from transmitting continuously for a long period of time 
as much as possible. The temperature of the main body will 
rise and this may result in burns and equipment failure due to 
overheating.
•  “ERROR TX FREQ” will be displayed when attempting to 
transmit on a frequency that is not in the amateur band.

Communicatingusingtherepeater
This radio includes an ARS (Automatic Repeater Shift) function which permits 
communication through the repeater automatically just by setting the receiver to the 
repeater frequency.
1  Set the receive frequency to the repeater frequency
  “-” or “+” appears on top of the display.
2 Press [PTT], to begin communicating through the repeater
Tips
•  Press   and touch [REV] to reverse the transmission and reception frequencies temporarily to 
check whether direct communication with the partner station is 
possible.
•  When reversing the frequencies, [REV] will turn orange.
•  When [REV] is touched one more time, the reverse is cancelled.
•  When the settings are changed in the set-up menu, this radio can 
be used in even more convenient ways.
The ARS function can be turned off under “CONFIG” → “4 AUTO 
RPT SHIFT”.
The repeater shift direction can be set under “CONFIG” → “5 RPT SHIFT”.
The repeater shift width can be changed under “CONFIG” → “6 RPT SHIFT FREQ”.
 ●Repeatershift
The FTM-400XDR/DE has been configured, at the factory, for the repeater shifts 
customary in the country where it is sold. For the 144 MHz band, this usually will be 600 
kHz, while the 430 MHz shift will be 1.6 MHz or 7.6 MHz.
Depending on the part of the band in which you are operating, the repeater shift may 
be either downward (−) or upward (+), and one of these icons will appear on the display 
when repeater shifts have been enabled.
 ●Automaticrepeatershift(ARS)
The FTM-400XDR/DE ARS feature causes the appropriate repeater shift to be 
automatically applied whenever it is tuned into the designated repeater sub-bands.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
1 Press   for one second or longer
  The set-up menu will be displayed.
