TTY Mode
Your phone is fully Teletypewriter (TTY)/Telecommunication Device for
the Deaf (TDD) compatible. You connect TTY/TDD equipment to the
headset connector on the top of your phone, behind the folder hinge.
You can set your phone to allow TTY/TTD communication while you
converse with the other party, or you can limit voice communication
to Talking or Hearing only.
Note:
TTY Mode must be enabled before you can use your phone with TTY/TDD
equipment.
The TTY Mode option has no effect on the phone’s earpiece, microphone,
or speaker. When you select TTY Full, all currently enabled sound functions
remain enabled.
Voice Privacy
Voice Privacy lets you choose what level of voice security (
Standard
or
Enhanced
) your phone will use. When set to Enhanced, your R250
sounds an alert tone if the network’s voice security level drops to
Standard.
Tip:
You can change your Voice Privacy setting during a call by using the In-Use
Menu options. (See “In-Use Menu” on page 37 for more information.)
You can set your phone to alert you when Voice Privacy support changes. (For
more information, refer to “Alerts” on page 126.)
