• Replace n with 0 for TTY Off mode. Users who can hear and talk can turn
off TTY support.

this mode to send and receive text messages through a TTY device.
• Replace n with 2 for VCO mode. Users who can talk but cannot hear can use
this mode to talk through the phone and receive responses via text messages.
