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 750.
Pacemakers The Health Industry Manufacturers Association 
recommends that a minimum separation of six inches (6") be 
maintained between a Treo 750 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 Treo 750 more than six inches from their 
pacemaker when the Treo 750 is turned ON. 
• Not carry the Treo 750 in a breast pocket.
• Use the ear opposite the pacemaker to minimize the potential for 
interference.
• Turn the Treo 750 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 
Treo 750 models. You may want to consult your doctor in the event of 
you experience interference with your hearing aid while using your 
Treo 750. When using the speakerphone feature, it is recommended 
that you place your Treo 750 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 Treo 750 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 Treo 750, 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 Treo 750 user should experience any disorientation, loss 
of awareness, convulsion, eye or muscle twitching or other 
involuntary movements, stop use immediately and consult a doctor. 
Individuals with personal or family history of such events should 
consult a doctor before using the device. To limit the possibility of 
such symptoms, wherever possible every hour take a minimum of 15 
minutes, use in a well lighted area, view the screen from the farthest 
distance and avoid exposure to blinking lights if you are tired. 
Aircraft While in aircraft, follow all instructions regarding the 
operation of your Treo 750. Use of your Treo 750 while on board on 
aircraft must be done in accordance in compliance with airline 
instructions and regulations.
Veh icle s  wi t h Ai r  Bag s Your Treo 750 should not be placed in a 
position that would affect the operation of air bag deployment or in a 
position that, should the air bag inflate, could propel the Treo 750. Air 
bags will inflate with great force and care should be taken to protect 
within a vehicle that has air bags.
Battery Your Treo 750 includes an internal lithium ion battery. 
Please note that use of certain data applications can result in heavy 
battery use and may require frequent battery charging. Any disposal 
of the Treo 750 must comply with laws and regulations pertaining to 
lithium ion batteries.
