There are many different types of triggers and many more combinations of those types.
See the TIA standard for more information about triggers.
Triggers are divided into two types. One Shot triggers happen once and then are complete.
Periodic triggers happen periodically. Triggers may have start and stop times. Triggers
will only be armed within their specified start/stop times.
Triggering can be started both by commands from an LSHS and from programming.
Triggers marked with a * below are programmable.
The radio only supports a single trigger of each type. Sending a new trigger of a type that
is already in use will overwrite the existing trigger. This includes triggers set by the LSHS
and programming software.
The following table shows the supported triggers. The radio does not support
combinations of triggers.

Description
This trigger happens once at the time specified in the Triggered-
Location-Request.
This trigger happens once when the user PTTs the radio. This trigger
is activated when the user presses the PTT button but the data will
usually be sent after the call is over. We do this to avoid delaying the
call.
This trigger happens once when the user puts the radio into
emergency.
This trigger happens every period specified by the Triggered-
Location-Request.
