MonitoringtheHomeChannel
This radio is equipped with a dual receive function (also known as dual watch (DW)) 
which checks for a signal on the home channel approximately every three seconds 
while monitoring or scanning. If a signal is detected, the home channel is received for 
five seconds, and then monitoring or scanning with dual receive is resumed.

When the home channel is busy, 
the radio receives the signal for 
five seconds and then starts the

Caution
When shipped from the factory, the default frequency in the home channel of 144 MHz Band is set 
to 144.000 MHz while the default frequency in the home channel of 430 MHz Band is set to 430.000 
MHz. These channels may be changed to a favorite operating frequency ( P.64).

Using the GPS Function
This radio is equipped with an internal GPS reception unit to receive and display the 
position information at all times. The position information can be used as in the following 
example.
Save the position information in the memory and use it for navigation purposes
  Refer to “Using the backtrack function” (Page 95)
Save the stations with frequent communications and checks whether they are 
within the sphere of communications
  Refer to the separate “Operating Manual GM Edition”
Exchange position information and messages through data communications with 
other stations
  Refer to the separate “Operating Manual APRS Edition”
WhatisGPS?
GPS or Global Positioning System is a satellite location system to determine the current 
position on earth. It is a military system developed by the US Department of Defense 
with approximately 30 GPS satellites circumnavigating the earth at an altitude of about 
20,000 km, When signals from three or more satellites in space are received, the 
current position information (longitude, latitude, altitude etc.) may be determined within 
an accuracy of several meters. The accurate time can also be received from the atomic 
clock built into the GPS satellite.
PositioningUsingGPS
1 Press   for one second or longer to switch on the 
power
  The satellite search will begin and the “ ” icon will 
be displayed at the top right of the screen.
 Tips   •  It may take several minutes to capture the satellites.
  •  When three or more satellites cannot be captured, the 
icon display will disappear. In this case, positioning is 
not possible and the position information cannot be 
used.

AboutGPSpositioning
Positioning refers to the calculation of one’s own position from the satellites orbit information and 
the transmission time of the radio waves. Positioning requires that three or more satellites be 
acquired. When positioning cannot be carried out properly, move to an open space as far away 
from buildings as possible and where there are fewer obstructions.
●Abouttheerror
Depending on the surrounding environment of the receiver location, an error of several hundred 
meters may occur. Although positioning is possible using only three satellites, depending on the 
positioning conditions, the positioning accuracy may become worse, or may no longer be possible 
under the following conditions:
•  Between high rise buildings, narrow roads between buildings, indoors and under the shade of 
buildings, below high voltage lines and underneath overhead structures, between trees and 
shrubs such as in forests and woods, inside tunnels and underground, when used behind a solar-
energy reflecting glass, locations where a strong magnetic field occurs
●Whennotusingtheradioforalongperiodoftime
When using the GPS function for the first time after purchasing the FTM-400XDR/DE transceiver, 
and when turning it on after It has not been used for a long period time, positioning may take 
several minutes in order to search for the satellites. Also, when using the device again several 
hours after switching off the power, positioning may take several minutes in order to search for the 
satellites.
PositioningusinganexternalGPSdevice
Commercial GPS receive devices can also be connected to the [EXT GPS] jack on the 
side of the controller.
The [EXT GPS] plug connector is illustrated below.

UsingtheSmartNavigationFunction
Two navigation methods may be used in the smart navigation function.
(1) Real-time navigation function
In the C4FM digital V/D mode, the position and direction of the received partner 
station can be displayed in real time during the communication because the position 
information obtained from the GPS is transmitted at the same time as the voice signal.
(2) Backtrack function
By registering the departure or other points in advance, the distance and direction 
from the current position to the registered location can be displayed in real time.

When using the navigation function, use the “Compass Screen” to display the direction 
of your station and the partner station on a compass.
