palmOne Treo 600 Using Manual page 161

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 Treo 600 is compatible with select TTY devices. You can
connect a TTY/TDD machine to your phone 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
Verizon. Please contact their customer service department for more
information.

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 phone. In particular, turn
off your phone when you are in any areas with a potentially explosive
atmosphere, such as 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 Treo.
Pacemakers The Health Industry Manufacturers Association
recommends that a minimum separation of six inches (6") be maintained
between a handheld wireless phone 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 phone more than six inches from their pacemaker
when the phone is turned ON.
•Not carry the phone in a breast pocket.
•Use the ear opposite the pacemaker to minimize the potential for
interference.
•Turn the phone 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
wireless phones. You may want to consult your doctor in the event of you
experience interference with your hearing aid while using Treo. When
using the speakerphone feature, it is recommended that you place Treo 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 phone 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.
Interference to Other Electronic Devices RF energy may affect
improperly installed or inadequately shielded electronic operating and
entertainment systems in motor vehicles. Check with the manufacturer or
representative to determine if these systems are adequately shielded from
external RF energy. Also check with the manufacturer of any equipment
that has been added to the vehicle.
Repetitive Motion Injuries When using the keyboard or playing games
on your phone, you may experience discomfort in your neck, shoulders,
hands, arms, of other parts of the body. To avoid any injury, such as
tendonitis, carpal tunnel syndrome, or other musculoskeletal disorder,
make sure to take necessary breaks from use, take longer rests (such as
several hours) if discomfort or tiring begins, and see a doctor if discomfort
persists.
