Safety

The FDA has been a leading participant in the World Health Organization International Electromagnetic Fields (EMF) Project since its inception in 1996. An influential result of this work has been the development of a detailed agenda of research needs that has driven the establishment of new research programs around the world. The project has also helped develop a series of public information documents on EMF issues.

The FDA and the Cellular Telecommunications & Internet Association (CTIA) have a formal Cooperative Research and Development Agreement (CRADA) to do research on wireless phone safety. The FDA provides the scientific oversight, obtaining input from experts in government, industry, and academic organizations. CTIA-funded research is conducted through contracts with independent investigators. The initial research will include both laboratory studies and studies of wireless phone users. The CRADA will also include a broad assessment of additional research needs in the context of the latest research developments around the world.

7.How can I find out how much radio frequency energy exposure I can get by using my wireless phone?

All phones sold in the United States must comply with Federal Communications Commission (FCC) guidelines that limit radio frequency energy (RF) exposures. The FCC established these guidelines in consultation with the FDA and the other federal health and safety agencies. The FCC limit for RF exposure from wireless telephones is set at a Specific Absorption Rate (SAR) of

1.6watts per kilogram (1.6 W/kg). The FCC limit is consistent

with the safety standards developed by the Institute of Electrical and Electronic Engineering (IEEE) and the National Council on Radiation Protection and Measurement. The exposure limit takes into consideration the body’s ability to remove heat from the tissues that absorb energy from the wireless phone and is set well below levels known to have effects. Manufacturers of wireless phones must report the RF exposure level for each

model of phone to the FCC. The FCC website (http://www.fcc.gov/oet/ rfsafety) gives directions for locating the FCC identification number on your phone so you can find your phone’s RF exposure level in the online listing.

8.What has the FDA done to measure the radio frequency energy coming from wireless phones?

The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical standard for measuring the radio frequency energy (RF) exposure from wireless phones and other wireless handsets with the participation and leadership of FDA scientists and engineers. The standard, “Recommended Practice for Determining the Spatial-Peak Specific Absorption Rate (SAR) in the Human Body Due to Wireless Communications Devices: Experimental Techniques,” sets forth the first consistent test methodology for measuring the rate at which RF is deposited in the heads of wireless phone users. The test method uses a tissue-simulating model of the human head. Standardized SAR test methodology is expected to greatly improve the consistency of measurements made at different laboratories on the same phone. SAR is the measurement of the amount of energy absorbed in tissue, either by the whole body or a small part of the body. It is measured in watts/kg (or milliwatts/g) of matter. This measurement is used to determine whether a wireless phone complies with safety guidelines.

9.What steps can I take to reduce my exposure to radio frequency energy from my wireless phone?

If there is a risk from these products — and at this point we do not know that there is — it is probably very small. But if you are concerned about avoiding even potential risks, you can take a few simple steps to minimize your exposure to radio frequency energy (RF). Since time is a key factor in how much exposure a person receives, reducing the amount of time spent using a wireless phone will reduce RF exposure.

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.
