Appendix B

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 FDA done to measure the radiofrequency energy coming from wireless phones?

The Institute of Electrical and Electronic Engineers (IEEE) is developing a technical standard for measuring the radiofrequency 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 radiofrequency 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 radiofrequency 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. If you must conduct extended conversations by wireless phone every day, you could place more distance between your body and the source of the RF, since the exposure level drops off dramatically with distance. For example, you could use a headset and carry the wireless phone away from your body or use a wireless phone connected to a remote antenna.

Again, the scientific data do not demonstrate that wireless phones are harmful. But if you are concerned about the RF exposure from these products, you can use measures like those described above to reduce your RF exposure from wireless phone use.

10.What about children using wireless phones?

The scientific evidence does not show a danger to users of wireless phones, including children and teenagers. If you want to take steps to lower exposure to radiofrequency energy (RF), the measures described above would apply to children and teenagers using wireless phones. Reducing the time of wireless phone use and increasing the distance between the user and the RF source will reduce RF exposure.Some groups sponsored by other national governments have advised that children be discouraged from using wireless phones at all. For example, the government in the United Kingdom distributed leaflets containing such a recommendation in December 2000. They noted that no evidence exists that using a wireless phone causes brain tumors or other ill effects. Their recommendation to limit wireless phone use by children was strictly precautionary; it was not based on scientific evidence that any health hazard exists.

6670 specifications

The Nokia 6670, launched in 2004, is a classic example of early 2000s mobile technology and remains an iconic device for many enthusiasts of vintage phones. It is often remembered for its robust design, impressive features for its time, and significant contributions to the consumer mobile market.

One of the standout features of the Nokia 6670 is its clamshell design, which combines portability with style. The phone measures 90 x 46 x 24 mm, making it compact enough to fit in a pocket while still providing a reasonably spacious keypad. Weighing just about 120 grams, it was known for being light yet durable.

The Nokia 6670 is powered by Symbian OS, specifically version 7.0s, allowing for a smooth user interface and multitasking capabilities that were advanced for its era. The device is equipped with a 1.3 MP camera, which was quite impressive for mobile phones at that time, enabling users to capture decent-quality photos. The phone also supported video capture, marking it as one of the early entrants into mobile photography.

In terms of display, the Nokia 6670 boasts a 176 x 208 pixels color screen, which enhances user experience through vivid visuals for applications and images. It supports a range of multimedia formats, allowing users to play videos, listen to music, and enjoy Java games—a significant feature given the escalating popularity of mobile gaming.

Connectivity-wise, the Nokia 6670 supports GPRS and WAP, enabling users to access the internet and download content, although the speeds were relatively slow compared to modern standards. Bluetooth technology also allows for wireless device pairing, which was quite innovative for a phone released in its period.

The Nokia 6670 supports expandable memory via a memory card slot, enabling users to store additional photos, music, and files. With a battery life of up to 6 hours of talk time and a standby time of around 300 hours, it provided a reliable performance that appealed to a wide audience.

With its combination of style, functionality, and advanced technology for its time, the Nokia 6670 has etched a place in mobile history. While much has changed in the world of smartphones, the Nokia 6670 remains a symbol of innovation from a bygone era and serves as a nostalgic reminder of the evolution of mobile technology.
