ON: Extends the APRS beacon transmission time interval when your own station is
stopped.
When DECAY is set to ON and your own station enters into the stop mode,
the "INTERVAL" setting will shift to a higher value one step at a time and the
interval will gradually be extended (to a maximum of 30 minutes).
(Example) When stopping with the INTERVAL set at 1 min
The interval will be extended in the following order: 2 min
→ 3 min → 5 min → 10 min → 15 min → 20 min → 30 min
→ 30 min...
When movement starts again, a beacon is automatically sent out once, at which
point the interval will automatically return to the "INTERVAL" setting.
When the "INTERVAL" setting reaches 30 min / 60 min, the transmission time
interval will not be extended further.
OFF: The APRS beacon transmission time interval is not extended.

Set the timer for limiting automatic transmission from
the last beacon transmission to a certain period of

period of time when "DECAY" is set to ON in the stationary state, and movement is
detected immediately after the beacon is automatically transmitted. The beacon will
not be automatically transmitted within this period of time. Only when the set time
has passed will the beacon be automatically sent out again.

The time can be set between 5 sec and 180 sec.
