Field Description Tone Length, Level, Mute

Field	Description

Tone Length	DTMF (Dual Tone Multi-Frequency) is the
	system used by touch tone phones under
	which a specific frequency or tone is
	assigned to each key. There is a standard
	length for these tones. However, some
	voice mail systems require a shorter or
	longer than normal length tone.
	This field allows you to set the AirCard to
	use a shorter or longer tone for systems
	that require it.
	The recommendation is to select normal
	unless your service provider indicates that
	a different tone length is required.

Level	This field allows you to adjust the volume of
	the beep that occurs when you click
	buttons on the dial pad.
	From the drop-down list, select a number.
	A higher number will give a louder beep.

Mute	When DTMF mute is enabled, there is no
	audible tone while the AirCard dials.
	Use the check box to enable and disable
	the feature. (The feature is enabled when
	checked.)

Minute Alert	This field allows you to enable and disable
	the Minute Alert feature.
	When enabled, the AirCard beeps at one
	minute intervals while you are on voice
	calls. This allows you to keep track of the
	duration of your call.
	Use the check box to enable and disable
	the feature. (The feature is enabled when
	checked.)
