11.What about wireless phone interference with medical equipment?

Radiofrequency energy (RF) from wireless phones can interact with some electronic devices. For this reason, FDA helped develop a detailed test method to measure electromagnetic interference (EMI) of implanted cardiac pacemakers and defibrillators from wireless telephones. This test method is now part of a standard sponsored by the Association for the Advancement of Medical instrumentation (AAMI). The final draft, a joint effort by FDA, medical device manufacturers, and many other groups, was completed in late 2000. This standard will allow manufacturers to ensure that cardiac pacemakers and defibrillators are safe from wireless phone EMI. FDA has tested hearing aids for interference from handheld wireless phones and helped develop a voluntary standard sponsored by the Institute of Electrical and Electronic Engineers (IEEE). This standard specifies test methods and performance requirements for hearing aids and wireless phones so that no interference occurs when a person uses a compatible phone and a accompanied hearing aid at the same time. This standard was approved by the IEEE in 2000.

FDA continues to monitor the use of wireless phones for possible interactions with other medical devices. Should harmful interference be found to occur, FDA will conduct testing to assess the interference and work to resolve the problem.

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.
