Note:

◆With “AUTO” in Menu 2–9 and Beacon ON, pressing [OK] in step 4 causes the APRS data to be immediately transmitted. After that, the APRS data is transmitted at intervals of the selected period.

◆While signals are present, APRS data is not transmitted after the interval. Approximately 2 seconds after signals drop, transmitting is executed.

RESTRICTING RECEPTION OF APRS DATA

If APRS is popular in your country, you may receive too many APRS packets for a short period. If this disturbs your APRS activities, specify a distance from your location. You will not receive APRS data from stations beyond this distance.
