Appendix B Message from the FDA

FDA shares regulatory responsibilities for wireless phones with the Federal Communications Commission (FCC). All phones that are sold in the United States must comply with FCC safety guidelines that limit RF exposure. FCC relies on FDA and other health agencies for safety questions about wireless phones. FCC also regulates the base stations that the wireless phone networks rely upon. While these base stations operate at higher power than do the wireless phones themselves, the RF exposures that people get from these base stations are typically thousands of times lower than those they can get from wireless phones. Base stations are thus not the subject of the safety questions discussed in this document.

3. What kinds of phones are the subject of this update?

The term wireless phone refers here to hand-held wireless phones with built-in antennas, often called cell mobile or PCS phones. These types of wireless phones can expose the user to measurable radiofrequency energy (RF) because of the short distance between the phone and the user’s head. These RF exposures are limited by Federal Communications Commission safety guidelines that were developed with the advice of FDA and other federal health and safety agencies. When the phone is located at greater distances from the user, the exposure to RF is drastically lower because a person's RF exposure decreases rapidly with increasing distance from the source. The so-called cordless phones; which have a base unit connected to the telephone wiring in a house, typically operate at far lower power levels, and thus produce RF exposures far below the FCC safety limits.

4. What are the results of the research done already?

The research done thus far has produced conflicting results, and many studies have suffered from flaws in their research methods. Animal experiments investigating the effects of radiofrequency energy (RF) exposures characteristic of wireless phones have yielded conflicting results that often cannot be repeated in other laboratories. A few animal studies, however, have suggested that low levels of RF could accelerate the development of cancer in laboratory animals. However, many of the studies that showed increased tumor development used animals that had been genetically engineered or treated with cancer-causing chemicals so as to be pre-disposed to develop cancer in the absence of RF exposure. Other studies exposed the animals to RF for up to 22 hours per day. These conditions are not similar to the conditions under which people use wireless phones, so we don’t know with certainty what the results of such studies mean for human health.

Three large epidemiology studies have been published since December 2000. Between them, the studies investigated any possible association between the use of wireless phones and primary brain cancer, glioma, meningioma, or acoustic neuroma, tumors of the brain or salivary gland, leukemia, or other cancers. None of the studies demonstrated the existence of any harmful health effects from wireless phone RF exposures. However, none of the studies can answer questions about long-term exposures, since the average period of phone use in these studies was around three years.

Nokia 3200 manual What kinds of phones are the subject of this update?, What are the results of the research done already?

3200 specifications

The Nokia 3200, released in 2003, is one of the notable entries in Nokia's lineup of mobile phones, targeting a youthful audience with its unique design and robust features. As one of the first phones to incorporate a camera in a compact format, it played an essential role in the evolution of mobile photography.

The Nokia 3200 features a distinctive, colorful design with a removable faceplate that encouraged personalization, a significant trend at the time. Its easy-to-hold shape and relatively lightweight construction make it comfortable for daily use. The phone's display is a 128 x 128 pixel monochrome screen, which may seem minimal by today’s standards, but it was suitable for basic tasks like texting and browsing contacts.

One of the standout features of the Nokia 3200 is its built-in VGA camera. With a resolution of 640 x 480 pixels, users could capture moments on the go, although the image quality was limited compared to modern standards. The camera also allowed for basic editing features, enabling users to add frames and effects to their pictures.

In terms of connectivity, the Nokia 3200 supports GSM networks, making it reliable for voice calls and SMS messages. It does not support 3G or 4G, as these technologies were not yet widespread during its production. However, it featured WAP browsing capabilities, which enabled users to access limited internet services and email, a novel feature at that time.

The Nokia 3200 comes equipped with a range of built-in ringtones and supported downloadable polyphonic ringtones, which appealed to younger users looking to customize their devices. It also has a variety of pre-installed games, adding entertainment value for users beyond communication.

Battery life for the Nokia 3200 is commendable, offering up to 4.5 hours of talk time and over 300 hours on standby, ensuring that it could keep users connected throughout the day.

The phone’s memory is expandable via a Pop-Port connector, allowing users to enhance their storage capacity for images and contacts. Overall, the Nokia 3200 embodies the simple yet effective technology of the early 2000s, catering to a generation eager to embrace mobile communication and personalization in a new and innovative way. Its impact is a reminder of how far mobile technology has come and its lasting influence on the design philosophy in modern smartphones.
