About the Digital Group ID (DG-ID) feature

1. Digital Group ID (DG-ID) function allows using the two-digit ID numbers to commu-
nicate only with specific group members. The desired DG-ID number from 00 to 99
is set in advance by all the group members. This ID number may be set separately
for transmit and receive, when the same ID number is set for both transmit and re-
ceive, only group members with the same ID number will be heard. This feature may
be used to limit communication only to group members that have the same DG-ID
number. The GM function may also be utilized to automatically monitor whether
or not group member stations with the same DG-ID number are operating within
communication range.
The DG-ID number 00 detects signals with all ID numbers. Normally setting the ID
number to "00" for both transmit and receive will permit reception of the signals from
all other stations using the digital C4FM mode, regardless of the transmit DG-ID
number settings of the other stations.
Also note that when the receive DG-ID number of the transceiver is set to a DG-ID
number other than "00", received signals that do not have the same DG-ID number
may not be heard.
2. When accessing a C4FM digital repeater controlled by a DG-ID number, set the
transmit DG-ID number of the FT3DR/DE to that of the repeater input. Even in that
case, if the receive DG-ID number of the FT3DR/DE is set to "00", all the downlink
signals from the repeater may be received.

Communicating with the DG-ID feature

• Digital C4FM mode transceivers compatible with the DG-ID function are required in order
to utilize this function.
• If the firmware is not compatible with the DG-ID function, update to the latest firmware to
use the DG-ID function. The latest firmware is available on the YAESU website.
Setting the transmit and receive DG-ID number to "00" to communicate with
all other stations using C4FM digital mode
1. Press and hold the [GM] key.
The DG-ID number setting screen will be displayed.
If the transmit DG-ID (DG-ID TX) number is not set
to "00", press the [GM] key, and then rotate the DIAL
knob to set "00".
2. Press the [GM] key again to select the receive DG-ID
(DG-ID RX).
If the receive DG-ID number is not set "00", press the
[GM] key then rotate the DIAL knob to set "00".
