Using TTY
A TTY (also known as TDD or text telephone) is a
telecommunications device that allows people who are deaf or
hard of hearing, or who have speech or language disabilities, to
communicate by telephone.
Your Palm Treo 750v smartphone is compatible with select TTY
devices. You can connect a TTY/TDD machine to your smartphone
through the headset jack, but you cannot use your headset jack
with a headset or hands-free kit while this mode is enabled.
Please check with the manufacturer of your TTY device for
connectivity information and to ensure that the TTY device
supports digital wireless transmission.
To use TTY, you may need to make additional arrangements with
your network operator. Please contact your network operator's
customer service department for more information.

5 Press OK. A keyboard icon appears at the top of your Today
screen whenever TTY is enabled.

Operational Warnings
IMPORTANT INFORMATION ON SAFE AND EFFICIENT
OPERATION. Read this information before using your integrated
multi-service portable radio.
For the safe and efficient operation of your radio, observe these
guidelines:
Potentially Unsafe Areas/Potentially explosive
atmospheres Obey all signs and instructions regarding turning off
your smartphone. In particular, turn off your smartphone when you
are in any areas with a potentially explosive atmosphere, such as

R E G U L A T O R Y I N F O R M A T I O N
fueling areas (gas or petrol stations, below deck on boats), storage
facilities for fuel or chemicals, blasting areas and areas near electrical
blasting caps, and areas where there are chemicals or particles (such
as metal powders, grains, and dust) in the air.
Interference to Medical and Personal Electronic Devices Most
but not all electronic equipment is shielded from RF signals and
certain electronic equipment may not be shielded against the RF
signals from your smartphone.
Pacemakers The Health Industry Manufacturers Association
recommends that a minimum separation of six inches (6") be
maintained between a smartphone and a pacemaker to avoid
potential interference with the pacemaker. These recommendations
are consistent with the independent research by the
recommendations of Wireless Technology Research.
Persons with pacemakers should:
• ALWAYS keep the smartphone more than six inches from their
pacemaker when the smartphone is turned ON.
• Not carry the smartphone in a breast pocket.
• Use the ear opposite the pacemaker to minimize the potential for
interference.
• Turn the smartphone OFF immediately if you have any reason to
suspect that interference is taking place.
Audio Safety Some hearing aids may be affected by some digital
smartphones. You may want to consult your doctor in the event of
you experience interference with your hearing aid while using your
smartphone. When using the speakerphone feature, it is
recommended that you place your smartphone at a safe distance
from your ear.
Other Medical Devices If you use any other personal medical
device, consult the manufacturer of your device to determine if it is
adequately shielded from external RF energy. Your physician may be
able to assist you in obtaining this information.
Turn your smartphone OFF in health care facilities when any
regulations posted in these areas instruct you to do so. Hospitals or
health care facilities may be using equipment that could be sensitive
to external RF energy.
