Extras Menu 41
If you want to switch from handheld to TTY operation
(after you are in TTY mode), simply re-insert the 2.5 mm
plug into the handset jack. You will know your phone is
back in TTY operation because the TTY symbol will
reappear in the lower lefthand corner of your display.
Headset Jack
You can use your TTY terminal with your Sony Ericsson
mobile phone. The following is a list of options available
under the
Headset Jack menu:
•Use SonyEricssonPHF with the portable hands-free
accessory that comes in the kit (default setting).
• In-Ear PHF improves intelligibility with third-party
portable handsfree devices that fit in the ear canal.
• Over-Ear PHF improves the intelligibility with third-
party portable handsfree devices that hook over and
rest outside the ear.
• Select TTY to work with TTY devices.
• Vehicle HF reduces echo heard by remote party when
using third-party vehicle handsfree device which is
typically powered by the cigarette lighter.
To work with a TTY accessory, activate TTY by scrolling
to
TTY in the Extras, Headset Jack menu, and pressing
Select.
Your phone is now set to work with a recommended TTY
device. To verify that your phone is in TTY Mode, insert
the TTY cable end 2.5 mm plug into your phone’s audio
jack (to the right of the display).
TTY will display in small
print on the lower left corner of the display. You can now
accept and send TTY calls.
Optimum Use
TTY communications can be conducted from moving
vehicles, however, it may be dangerous to operate a
vehicle and communicate on your mobile phone at the
same time. You may experience a higher character error
rate of the TTY conversation while in motion. For the
highest quality communications, it is best to remain
stationary.
Note!
Your Sony Ericsson mobile phone has a menu
timer that clears the display if a key is not
pressed within 19 seconds.
