FDA Consumer Update

The U.S. Food and Drug Administration’s Center for Devices and Radiological Health Consumer Update on Mobile Phones:

1. Do wireless phones pose a health hazard?

The available scientific evidence does not show that any health problems are associated with using wireless phones. There is no proof, however, that wireless phones are absolutely safe. Wireless phones emit low levels of radiofrequency energy (RF) in the microwave range while being used. They also emit very low levels of RF when in the standby mode. Whereas high levels of RF can produce health effects (by heating tissue), exposure to low level RF that does not produce heating effects causes no known adverse health effects. Many studies of low level RF exposures have not found any biological effects. Some studies have suggested that some biological effects may occur, but such findings have not been confirmed by additional research. In some cases, other researchers have had difficulty in reproducing those studies, or in determining the reasons for inconsistent results.

2.What is the FDA's role concerning the safety of wireless phones?

Under the law, the FDA does not review the safety of radiation- emitting consumer products such as wireless phones before they can be sold, as it does with new drugs or medical devices. However, the agency has authority to take action if wireless phones are shown to emit radiofrequency energy (RF) at a level that is hazardous to the user. In such a case, the FDA could require the manufacturers of wireless 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, the FDA has urged the wireless phone industry to take a number of steps, including the following:

Support needed research into possible biological effects of RF of the type emitted by wireless phones;

Design wireless phones in a way that minimizes any RF exposure to the user that is not necessary for device function; and

Cooperate in providing users of wireless phones with the best possible information on possible effects of wireless phone use on human health.

The FDA belongs to an interagency working group of the federal agencies that have responsibility for different aspects of RF safety to ensure coordinated efforts at the federal level. The following agencies belong to this working group:

National Institute for Occupational Safety and Health

Environmental Protection Agency

Occupational Safety and Health Administration

National Telecommunications and Information Administration

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

The 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. The FCC relies on the FDA and other health agencies for safety questions about wireless phones.

The 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.

VX4500 specifications

The LG Electronics VX4500 is a significant mobile device that garnered attention when it was launched in the early 2000s, known for blending functionality with an appealing design. It primarily targeted users seeking reliability alongside a compact form factor.

One of the standout features of the VX4500 is its clamshell design, which not only protects the keypad and screen when closed but also delivers a sleek appearance. The phone incorporates a vibrant color display with a resolution of 128 x 160 pixels, providing clear visuals that enhance user experience, especially when navigating menus or viewing text messages.

Technologically, the VX4500 supports CDMA networks, enabling it to deliver robust voice quality and reliable connectivity. Additionally, it is equipped with a speakerphone feature, allowing for hands-free communication, which proved particularly useful for users on the go. The device also includes a vibrating alert option, ensuring users never miss important calls or messages, even in loud environments.

Another significant characteristic of the LG VX4500 is its camera functionality. The built-in VGA camera allows users to capture moments on the go, embracing the growing trend of mobile photography at that time. Although simple by today's standards, this feature was a noteworthy addition, providing users with the ability to share images quickly.

The VX4500 is powered by a long-lasting battery, which ensures extended talk time and standby time, making it an ideal choice for those who prioritize reliability in their mobile devices. With a battery life of up to 300 hours on standby and close to 4 hours of talk time, users could depend on the phone for their daily communication needs without frequent recharging.

In addition to its communication features, the VX4500 offers various utilities, including a calendar, alarm clock, and voice memo capabilities. These functionalities position it as not only a phone for calls but also a practical companion for organizing daily tasks.

Overall, the LG Electronics VX4500 encapsulates the core values of early 2000s mobile technology—durability, ease of use, and essential features—all packed into a pocket-friendly design. While technology has evolved significantly since then, the VX4500 remains a nostalgic representation of the era of flip phones, catering to a user base that appreciated straightforward mobile communication without the complexities of modern smartphones.
