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 lat- est research developments around the world.

7.How can I find out how much radiofrequency 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 radiofre- quency energy (RF) exposures. FCC established these guidelines in consultation with 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 1.6 watts 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 FDA done to measure the radiofrequency energy coming from wireless phones ?

The Institute of Electrical and Electronic Engineers (IEEE) is devel- oping a technical standard for measuring the radiofrequency ener- gy (RF) exposure from wireless phones and other wireless hand- sets 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 tis- sue, either by the whole body or a small part of the body. It is meas- ured 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 con- cerned about avoiding even potential risks, you can take a few sim- ple 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 dramati- cally 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 wire- less phones, including children and teenagers. If you want to take steps to lower exposure to radiofrequency energy (RF), the meas- ures described above would apply to children and teenagers using wireless phones. Reducing the time of wireless phone use and

Audiovox CDM 8450 owner manual What about children using wireless phones?

CDM 8450 specifications

The Audiovox CDM 8450 is a mobile phone that was notable during its time for offering a blend of essential features and reliability targeted primarily at users who valued straightforward functionality alongside certain modern conveniences. Launched in the early 2000s, this device had an appealing design that often attracted users looking for a compact, easy-to-use handset.

One of the key features of the Audiovox CDM 8450 was its dual-mode capability, allowing it to function on both CDMA and analog networks. This dual functionality meant that users could enjoy coverage in areas where CDMA service was not available, ensuring a wider range of connectivity options.

The phone also boasted a well-designed interface that included a vibrant color display, which was relatively advanced for its time. The display enabled users to easily navigate through menus and access various features. An intuitive keypad layout provided comfortable typing and dialing, rounded off with a compact size ideal for carrying in pockets or bags.

In terms of multimedia, the CDM 8450 supported basic SMS and picture messaging, which was becoming increasingly popular. Users were able to send and receive text messages seamlessly, enhancing communication possibilities. Although it did not offer the sophisticated multimedia capabilities seen in later smartphones, the phone's simplicity allowed it to excel in basic communication tasks.

The Audiovox CDM 8450 was powered by a robust battery that provided reliable talk and standby time, crucial for users on the go. The durability of the battery was one of the strong selling points, making it a dependable option for those who needed their phone to last throughout the day.

For connectivity, the device offered infrared capability, which allowed users to transfer small amounts of data between devices quickly. This feature was useful for sharing contacts or calendar information with others without needing physical connections.

The phone was also equipped with an array of features such as a built-in speakerphone, customizable ringtones, and an address book that could store a substantial number of contacts. The solid build quality and user-friendly features made the Audiovox CDM 8450 a popular choice among consumers looking for a capable and affordable mobile phone during its era. Overall, the Audiovox CDM 8450 represents a stepping stone in the evolution of mobile technology, laying the groundwork for more advanced devices in the future.
