Using This Guide

The MobileAccess™ T255 phone combines two separate devices – a wireless voice phone and a wireless data terminal.
The voice phone can be used where cellular service is available. It works over 800 MHz digital/analog and 1900 MHz digital networks.
To access wireless data service, you must be in an area where wireless IP (CDPD) service is provided. Your network service provider must set up and register a unique IP and email address for you.
As you use the phone, keep in mind these two points:
• The phone cannot operate simultaneously as a voice phone and a data terminal. Pressing the MODE key allows you to switch between Voice Mode and Data Mode. In some instances, the phone will automatically switch modes.
• Some of the phone’s keys have different functions depending on whether you’re in Voice Mode or Data Mode. See Key Functions, pages 4-5.

Safety Information

EXPOSURE TO RADIO FREQUENCY SIGNALS
Your wireless handheld portable telephone is a low power radio trans­mitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) signals.
In August 1996, the Federal Communications Commissions (FCC) adopt­ed RF exposure guidelines with safety levels for hand-held wireless phones. These guidelines are consistent with the safety standards previ­ously set by both U.S. and international standards bodies:
*ANSI C95.1 (1992) *NCRP Report 86 (1986) *ICNIRP (1996)
*American National Standards Institute; National Council on Radiation Protection and Measure­ments; International Commission on Non-Ionizing Radiation Protection
Those standards were based on comprehensive and periodic evaluations of the relevant scientific literature. For example, over 120 scientists, en­gineers, and physicians from universities, government health agencies, and industry re viewed the avai lable body of researc h to develop t he ANSI Standard (C95.1).
The design of your phone complies with the FCC guidelines (and those standards).
Your phone has been tested and meets the limits for radio frequency (RF) exposure set by the FCC for normal handheld use next to the ear or worn on the body using a Mitsubishi brand belt clip accessory specified for this phone, and used as intended. Operation of the phone in other situations such as in shirt pockets or non-Mitsubishi brand belt clips or holsters, or operation with the back of the phone closer than 1 3 mm (0.51”) to the body, have not been tested. Therefore operation of the phone in non­tested situations may not meet the limits for RF exposure set by the FCC and must be avoided.
ANTENNA CARE
Use only the supplied or an approved replacement antenna. Unauthor­ized antennas, modifications, or attachments could damage the phone and may violate FCC regulations.
PHONE OPERATION
NORMAL POSITION: Hold the phone as you would any other telephone with the antenna pointed up and over your shoulder.
15
EFFICIENT OPERATION: For your phone to operate most efficiently, do not touch the antenna unnecessarily when the phone is in use. Contact with the antenna affects call quality and may cause the phone to operate at a higher power level than o therw ise needed.
DRIVING
Check the laws and regulations on the use of wireless telephones in the areas where you drive. Always obey them. Also, if using your phone while driving, please:
• Give full attention to driving - driving safely is your first responsibility.
• Use hands-free operation, if available.
• Pull off the road and park before maki ng or answerin g a call if drivi ng
conditions so require.
ELECTRONIC DEVICES
Most modern electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded against the RF signals from your wireless phone.
Pacemakers The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches 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 and 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
• Should not carry the phone in a breast pocket
• Should use the ear opposite the pacemaker to minimize the poten­tial for interference
• If you have any reason to suspect that interference is taking place, turn your phone OFF immediately
Hearing Aids Some digital wireless phones may interfere with some hearing aids.
In the event of such interference, you may want to consult your serv­ice provider (or call the customer service line to discuss alternatives).
Other Medical Devices If you use any other personal medical device, consult the manufac­turer of your device to determine if they are adequately shielded from external RF energy. Your physician may be able to assist you in obtaining this information.
16
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.
Vehicles RF signals may aff ect improperly installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle. You should also consult the manufacturer of any equipment that has been added to your vehicle.
Posted Facilities Turn your phone OFF in any facility where posted notices so require.
AIRCRAFT
FCC regulations prohibit using your phone while in the air. Switch OFF your phone before boarding an aircraft.
BLASTING AREAS
To avoid interfering with blasting operations, turn your phone OFF when in a “blasting area” or in areas posted “Turn off two-way radio.” Obey all signs and instructions.
POTENTIALLY EXPLOSIVE ATMOSPHERES
Turn your phone OFF when in any area with a potentially explosive at­mosphere and obey all signs and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often but not always clearly marked. They include fueling areas such as gasoline stations; be­low deck on boats; fuel or chemical transfer or storage facilities; vehicles using liquefied petroleum gas (such as propane or butane); areas where the air contains chemicals or particles, such as grain, dust, or metal pow­ders; and any other area where you would normally be advised to turn off your vehicle engine.
For Vehicles Equipped with Air Bags
An air bag inflates with great force. DO NOT place objects, including both installed or portable wireless equipm ent, in the area over the air bag or in the air bag deployment area. If in-vehicle wireless equipment is im­properly installed and the air bag inflates, serious injury could result.

The U.S. Food and Drug Administration’s Center for Devices and Radiological Health
Consumer Update on Mobile Phones
FDA has been receiving inquiries about the safety of mobile phones, including cellular phones and PCS phones. The following summarizes what is known--and what remains unknown--about whether these products can pose a hazard to health, and what can be done to minimize any potential risk.
Why the concern?
Mobile phones emit low levels of radio frequency energy (i.e., radio frequency radiation) in the microwave range while being used. They also emit very low levels of radio frequency energy (RF), considered non­significant, when in the stand-by mode. It is well known that high levels of RF can produce biological damage through heating effects (this is how your microwave oven is able to cook food). However, it is not known whether, to what extent, or through what mechanism, lower levels of RF might cause adverse health effects as well. Although some research has been done to address these questions, no clear picture of the biological effects of this type of radiation has emerged to date. Thus, the available science does not allow us to conclude that mobile phones are absolutely safe, or that they are unsafe. However, the available scientific evidence does not of mobile phones.
What kinds of phones are in question?
Questions have been raised about hand-held mob ile phones, the kind that have a built-in antenna that is positioned close to the user’s head during normal telephone conversation. These types of mobile phones are of concern because of the short distance between the phone’s antenna-
-the primary source of the RF--and the person’s head. The exposure to RF from mobile phones in which the antenna is located at greater distances from the user (on the outside of a car, for example) is drastically lower than that from hand-held phones, because a person’s RF exposure decreases rapidly with distance from the source. The safety of so-called ”cordless phones,” which have a base unit connected to the telephone wiring in a house and which operate at far lower power levels and frequencies, has not been questioned.
demonstra te any ad vers e health effect s asso ciate d with the use
18
How much evidence is there that hand-held mobile phones might be harmful?
Briefly, there is not enough evidence to know for sure, either way; how­ever, research efforts are on-going.
The existing scientific evidence is confl icting and many of the studies that have been done to date have suffered from flaws in their research meth­ods. Animal experiments investigating the effects of RF exposures char­acteristic of mobile phones have yielded conflicting results. A few animal studies, however, have suggested that low levels of RF could accelerate the development of cancer in laboratory animals. In one study, mice ge­netically altered to be predisposed to developing one type of cancer de­veloped more than twice as many such cancers when they were exposed to RF energy compared to controls. There is much uncertainty among sci­entists about whether results obtained from animal studies apply to the use of mobile phones. First, it is uncertain how to apply the results ob­tained in rats and mice to humans. Second, many of the studies that showed increased tumor development used animals that had already been treated with cancer-causing chemicals, and other studies expo sed the animals to the RF virtually continuously--up to 22 hours per day.
For the past five years in the United States, the mobile phone industry has supported research into the safety of mobile phones. This research has resulted in two findings in particular that merit additional study:
1. In a hospital-based, case-control study, researchers looked for an association between mobile phone use and
either glioma (a type of brain cancer) or acoustic neuroma (a benign tumor of the nerve sheath). No statistically significant association was found between mobile phone use and acoustic neuroma. There was also no association between mobile phone use and gliomas when all types of types of gliomas were considered together. It should be noted that the average length of mobile phone exposure in this study was less than three years.
When 20 types of glioma were considered separately, however, an association was found between mobile phone
use and one rare type of glioma, neuroepithelliomatous tumors. It is possible with multiple comparisons of the same sample that this association occurred by chance. Moreover, the risk did not increase with how often the mobile phone was used, or the length of the calls. In fact, the risk actually decreased with cumulative hours of mobile phone use. Most cancer causing agents increase risk with increased exposure. An ongoing study of brain cancers by the National Cancer Institute is expected to bear on the accuracy and repeatability of these results.
1
2. Researchers conducted a large battery of laboratory tests to assess the effects of exposure to mobile phone RF on
genetic material. These included tests for several kinds of abnormalities, including mutations, chromosomal aber­rations, DNA strand breaks, and structural changes in the genetic material of blood cells called lymphocytes. None of the tests showed any effect of the RF except for the micronucleus assay, which detects structural effects on the genetic material. The cells in this assay showed changes after exposure to simulated cell phone radiation, but only after 24 hours of exposure. It is possible that exposing the test cells to radiation for this long resulted in heating. Since this assay is known to be sensitive to heating, heat alone could have caused the abnormalities to occur. The data already in the literature on the response of the micronucleus assay to RF are conflicting. Thus, follow-up research is necessary.

19
FDA is currently working with government, industry, and academic groups to ensure the proper follow-up to these industry-funded research findings. Collaboration with the Cellular Telecommunications Industry Association (CTIA) in particular is expected to lead to FDA providing research recommendations and scientific oversight of new CTIA-funded research based on such recommendations.
Two other studies of interest have been reported recently in the literature:
1. Two groups of 18 people were exposed to simulated mobile phone signals under laboratory conditions while they performed cognitive function tests. There were no changes in the subjects’ ability to recall words, numbers, or pictures, or in their spatial memory, but they were able to make choices more quickly in one visual test when they were exposed to simulated mobile phone signals. This was the only change noted among more than 20 variables
3
compared.
2. In a study of 209 brain tumor cases and 425 matched controls, there was no increased risk of brain tumors associated with mobile phone use. When tumors did exist in certain locations, however, they were more likely to be on the side of the head where the mobile phone was used. Because this occurred in only a small number of cases, the increased likelihood was too small to be statistically significant.
4
In summary, we do not have enough information at this point to assure the public that there are, or are not, any low incident health problems associated with use of mobile phones. FDA continues to work with all parties, including other federal agencies and industry, to assure that research is undertaken to provide the necessary answers to the outstanding questions about the safety of mobile phones.
What is known about cases of human cancer that have been reported in users of hand-held mobile phones?
Some people who have used mobile p hones have been diag nosed wit h bra in cancer. But it is important to understand that this type of cancer also occurs among people who have not use d mobile phones. In fact, brain can cer occurs in the U.S. population at a rate of about 6 new cases per 100,000 people each year. At that rate, assuming 80 million users of mobile phones (a number increasing at a rate of about 1 million per month), about 4800 cases of brain cancer would be e xpected each year among th ose 80 m illion people, w hether or not they used their phones. Thus it is not possible to tell whether any individual’s cancer arose because of the phone, or whether it would have happened anyway.
A key questi on is whethe r the risk of getting a particular form of cancer is greater among people who use mobile phones than among the rest of the population. One way to answer that question is to compare the usage of mobile phones among people with brain cancer with the use of mobile phones among appropriately matched people without brain cancer. This is
20
called a case- control study. The cur rent cas e-contr ol stud y of brain cancer s by the National Cancer Institute, as well as the follow-up research to be sponsored by industry, will begin to generate this type of information.
What is FDA’s role concerning the safety of mobile phones?
Under the law, FDA does not review the safety of radiation-emitting con­sumer products such as mobile phones before marketing, as it does with new drugs or medical devices. However, the agency has authority to take action if mobile phones are shown to emit radiation at a level that is haz­ardous to the user. In such a case, FDA could require the manufacturers of mobile phones to notify users of the health hazard and to repair, replace or recall the phones so that the hazard no longer exists.
Although the existing scientific data do not justify FDA regulatory actions at this time, FDA has urged the mobile phone industry to take a number of steps to assure public safety. The agency has recommended that the industry:
support needed research into possible biological effects of RF of the
type emitted by mobile phones;
design mobile phones in a way that minimizes any RF exposure to the
user that is not necessary for device function ; and
cooperate in providing mobile phone users with the best possible
information on what is known about possible effects of mobile phone use on human health.
At the same time, FDA belongs to an interagency working group of the federal agencies that have responsibility for different aspects of mobile phone safety to ensure a coordinated effort at the federal level.
These agencies are:
National Institute for Occupational Safety and Health Environmental Protection Agency Federal Communications Commission Occupational Health and Safety Administration National Telecommunications and Information Administration
The National Institutes of Health also participates in this group.

In the absence of conclusive information about any possible risk, what can concerned individuals do?
If there is a risk from these products--and at this point we d o not know that there is--it is probably very small. But if people are concerned about avoiding even potential risks, there are simple steps they can take to do so. For example, time is a key factor i n how much exposure a person re­ceives. Those persons who spend long periods of time on their hand-held mobile phones could consider holding lengthy conversations on conven­tional phones and reserving the hand-held models for shorter conversa­tions or for situations when other types of phones are not available.
People who must conduct extended conversations in their cars every day could switch to a type of mobile phone that places more distance between their bodies and the source of the RF, since the exposure level drops off dramatically with distance. For example, they could switch to
a mobile phone in which the antenna is located outside the vehicle, a hand-held phone with a built-in antenna connected to a different
antenna mounted on the outside of the car or built into a separate package, or
a headset with a re mote ante nna to a mobil e phone ca rried at th e waist.
Again, the scientific data do not
demonstrate that mobile phones are harmful. But if people are concerned about the radio frequency energy from these products, taking the simple precautions outlined above can reduce any possible risk.
