PTT Setup
The PTT Setup box allows a secondary external function to be controlled with a separate relay closure at the same time as the
PTT relay. Select one (1) of the following:
PTT relay only - When selected, only the PTT relay is closed. (Default Setting)
PTT + R1 - When selected, both the PTT relay and the R1 relay close at the same time.
PTT + R2 - When selected, both the PTT relay and the R2 relay close at the same time.
PTT + BOTH - When selected, the PTT relay, the R1 relay, and the R2 relay close at the same time.

PTT Timeout Field

The PTT Timeout field is used to indicate how long, in seconds, to allow PTT to be active when no audio is transmitted. If a
time is entered in the field, PTT activity times out when no audio is transmitted for the designated amount of time. This feature
is useful in cases where the line goes offhook for an indefinite period of time due to a stuck PTT key.
The range for this field is 0 to 1800 sec.
Disabled is 0.
