Text Telephone (TTY) and Teletype Device for the
Deaf (TDD) device compatibility
Your Nokia phone is equipped with a universal 2.5mm accessory jack that
can be used to connect any “cellular ready” or “cellular compatible” TTY/
TDD device’s cable to your phone. It may be possible to connect the TTY/
TDD device to the bottom connector using the HDA-8 phone adapter.
However, Nokia recommends using the 2.5mm accessory jack for
optimum performance.
Important: Once your TTY/TDD device is connected to your phone,
you must use the phone’s menu (Menu - Settings - Accessory
settings - TTY) to enable the TTY/TDD mode.
