Entering only a “+” at the end of a stored number causes the phone to prompt you for a memory location after the call is connected. The phone expects a memory location after the “+” character. Enter a location number and press left F(OK) to send the contents of that memory location as Touch Tones.
Touch Tone Settings in the Phone
Your phone’s Touch Tone settings are Menu 4 3, Manual DTMF Tones, and Menu 4 4, Auto DTMF Length.
Menu 4 3, Manual DTMF Tones
Left F(Menu) 4 3 ’▼ to your choice
left F(OK)
This determines the length of the Individual Touch Tones when you press keys during calls. Note that regardless of this setting, strings of Touch Tones can be sent.
Continuous means the tone sounds for as long as you hold the key. Fixed sets the tone length to 100 ms, regardless of how long you press the key. Off turns the tones off, meaning that no tones are sent when you press individual keys.
Menu 4 4, Auto DTMF Length
Left F(Menu) 4 4 ’▼ to your choice
left F(OK)
This determines the length of Touch Tones in strings. Short sets the DTMF tone length to 100 ms. Long sets the DTMF tone length to 500 ms.
