Text Messaging Service

(Conventional System, Features)

Selects the Text Messaging mode for the current ASTRO Conventional System.

	Text Messaging is accessed by the radio-user with the Text Messaging Service button-press, or the Text Messaging Service menu-selection.
	Quick Text Messaging is accessed by the radio-user with the TMS Quick Text button-press.
	Query Messaging is accessed by the radio-user with the TMS Query button-press.

When the System Type field is set to "ASTRO", and

when a valid referenced Data Profile has been selected for the current System, and

when the radio is model / option capable.

When Text Messaging Service is used while in Data Scan and the Data Scan Preamble Length is increased or decreased from the default value, the Retry Short Timer needs to be increased or decreased accordingly. For example in Direct Data Mode of operation (see Packet Data Mode), if the value of the Data Scan Preamble Length is increased to 30 (from the default of 20), then the Retry Short Timer should be increased to 25 seconds (from the default of 15). For every 10 units added for Data Scan Preamble Length, the Retry Short Timer should be increased by 10 seconds.
