Support for TTY
Teletype (TTY) accessory, text phone, is an aid for people with
speech impairments.
To use the TTY device together with the P900
1. Connect the TTY device to the accessories connector at the
base of the P900.
2. In Phone, go to
Edit > Preferences > TTY Accessory
the check box to set the P900 into TTY mode.
Refer to the TTY device user manual to find out how to use the
device. It may be necessary to use an adapter between the TTY
device and the P900.
You can still make normal calls with the P900 in TTY mode but
other accessories such as handsfree will not work properly.
Do not open the Flip during a TTY call. It will impair the quality
of the connection.
Note Support for voice carry over (VCO) and hearing carry
over (HCO) is handled through the TTY device and not through
the phone.
