D-STAR INTRODUCTION
■ Communication Form in the DR mode
In the DR mode, the transceiver has three communica-
tion forms, as shown below.
• Local area call : To call through your local area (ac-
cess) repeater.
• Gateway call : To call through your local area (ac-
cess) repeater, repeater gateway and
the internet to your destination re-
peater or individual station's last used
repeater, using call sign routing.
• Simplex call : To call another station not using a re-
peater.

NOTE:
• Programming the repeater list is required for DR mode operation. (pp. 9-23 to 9-31)
• Before operating in the DV 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 a Time-Out Timer function for digital repeater operation. The timer limits a continuous trans-
mission to approximately 10 minutes. Warning beeps will sound approximately 30 seconds before time-out and
then again immediately before time-out.
