About the DR function

You can easily use D-STAR repeaters with the
D-STAR Repeater (DR) function. With this function,
you can select the preset repeater or frequency in
"FROM" (access repeater), and Your call sign in "TO"
(destination) on the DR screen, as shown below.
To display the DR screen, hold down
1 second.

(Repeater/Station)
Access repeater
NOTE: If the repeater set in "FROM" (Access
Repeater) has no Gateway, you cannot make a
Gateway call.

Ways to Communicate with the DR function

With the DR function, the transceiver has 3 ways to
communicate.
Local Area call: To call through your local area
(access) repeater.
Gateway call: To call through your local area (access)
repeater, repeater gateway, and the
Internet to your destination repeater or
individual station's last used repeater,
using Call Sign Routing.
Simplex call*: To call another station not using a
repeater.
* You can make a simplex call. (p .9-5)
NOTE:
• Using the repeater list is required to use the DR
function. (p. 9-11)
• Before operating in the Duplex mode, BE SURE
to check whether the repeater is busy, or not. If
the repeater is busy, wait until it is clear, or ask for
a ‛break' using a method acceptable to your local
procedures.
• The transceiver has the Time-Out Timer function
for the DV Repeater operation. The timer limits
a continuous transmission. Warning beeps will
sound approximately 30 seconds before time-out
and then again immediately before the time-out.
Enter your call sign (MY) into the transceiver. (p. 9-3)
Register your call sign (MY) to a gateway repeater. (p. 9-4)
Enter your D-STAR equipment into your registration form. (p. 9-4)
