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 650 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 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 wireless service provider. Please contact your wireless service provider's customer service department for more information. 1.

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 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. 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 smartphone, 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. Blackouts and Seizures Blinking lights, such as those experienced with television or playing video games, may cause some people to experience blackout or seizure, even if never experienced before. In the event a smartphone user should experience any disorientation, loss of awareness, convulsion, eye or muscle twitching or other involuntary movements, stop use immediately and consult a doctor.
