Consumer Information on Wireless Phones

The National Institutes of Health participates in some interagency working group activities, as well.

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 primary subject of the safety questions discussed in this document.

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 radio frequency 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 engineeredortreatedwithcancer-causingchemicalssoas to be pre-disposed to develop cancer in absence of RF exposure. Other studies exposed the animals to RF for up

SGH-x475 specifications

The Samsung SGH-x475 is a compact and stylish mobile phone that was launched in the early 2000s, representing a significant step in the evolution of mobile technology during that era. Aimed at users looking for a blend of functionality and design, the SGH-x475 featured a clamshell design that was not only fashionable but also practical, protecting the screen and keypad when not in use.

One of the standout features of the SGH-x475 is its lightweight construction. Weighing in at a mere 90 grams, it was designed for portability, making it easy to carry around in pockets or bags. The phone showcased a 1.5-inch monochrome display with a resolution of 128 x 128 pixels, which, while modest by today's standards, offered clear visibility for incoming calls, messages, and menu navigation.

The SGH-x475 supported both GSM 900 and 1800 bands, providing users with reliable connectivity across various regions. This dual-band capability was particularly advantageous for users who traveled frequently, as it ensured that they could stay connected across different networks. The phone also featured SMS (Short Message Service) capabilities, allowing users to send and receive text messages, which was becoming increasingly popular at the time.

In terms of battery life, the SGH-x475 was equipped with a removable lithium-ion battery that provided up to 7 hours of talk time and up to 200 hours of standby time. This longevity was essential for users on the go, ensuring that the phone could last through busy days without needing frequent recharging.

The phone incorporated several ringtones and offered a vibration alert feature, providing users with customizable options for notifications. Additionally, it had a built-in speakerphone function, enabling hands-free conversations, which was a budding trend among mobile users seeking convenience.

With a focus on user-friendly design, the SGH-x475 featured a straightforward menu system, making it accessible even for those unfamiliar with mobile technology. The keypad was laid out in a traditional format, with tactile feedback that made dialling and texting comfortable.

Overall, the Samsung SGH-x475 embodied the mobile technology of its time, balancing essential features, portability, and user comfort. Although it may seem basic compared to today’s smartphones, it played a pivotal role in the evolution of mobile communication during the early 2000s, leaving a lasting impact on users looking for reliable and stylish mobile solutions.
