Cleaning your WLAN Handset

The WLAN Handset occasionally must be cleaned to maintain appearance. In general, wiping the handset surface with a clean water-dampened cloth or paper towel removes most films or residues.

If more rigorous cleaning is required, you can use:

•A mild detergent solution. Be sure to wipe away any detergent residue with a plain water-dampened cloth.

•Any general-purpose household glass and surface cleaner. Do not spray the handset directly. Spray the cleaner on a soft cloth or paper towel, then wipe the handset.

•Pre-treated cloths, like those used for eyeglasses or cameras.

•Pre-moistened towelettes. Avoid those containing lanolin or aloe, which leave a slippery residue.

•Isopropyl alcohol, applied by a damp cloth or paper towel. When using alcohol, do not rub the keypad characters vigorously, as this will significantly degrade legibility.

IMPORTANT!

•Do not use furniture polishes, waxes, or plasticizer-based cleaner.

•Do not use lanolin, aloe, glycerin, or other skin care products.

•Do not apply any solvent such as acetone or mineral spirits.

•Do not directly spray or immerse the handset.

If the headset connector becomes dirty, you may experience a scratchy or intermittent signal. To clean the connector, dip the padded end of either a wooden- or paper-handled cotton swab in isopropyl alcohol. Gently insert in the connector and twist, repeating several times. If available, blow compressed air into the connector to clear debris.

2211, 2212 specifications

Nortel Networks, once a titan in the telecommunications arena, produced a variety of products that were pivotal in shaping the future of communication technologies. Among these products were the Nortel 2212 and 2211, which played a significant role in enterprise environments, particularly in the realm of voice over IP (VoIP) and unified communications.

The Nortel 2212 and 2211 are voice codecs used primarily in voice and video communications. They are built to handle multimedia transmissions over packet-switched networks, enhancing voice clarity and video quality. The 2212 codec is particularly noted for its ability to support a wide range of audio frequencies, which allows it to replicate sounds with greater fidelity. This is crucial in corporate settings where clear communication is imperative.

One of the standout features of both codecs is their ability to support multiple voice channels. The 2212 can handle up to 12 simultaneous voice calls, while the 2211 is optimized for smaller operations and can manage 11 calls effectively. This scalability is essential for businesses of varying sizes, enabling them to grow without needing substantial overhauls to their existing infrastructure.

In terms of technology, the Nortel 2212 and 2211 utilize advanced compression algorithms to minimize bandwidth usage while maintaining high audio quality. This is especially beneficial for organizations operating in areas with limited bandwidth or needing to cut costs related to data transmission. Nortel's technology optimizes the transmission over IP networks, making it suitable for VoIP, video conferencing, and even multimedia content delivery.

Additionally, both codecs are compliant with various standards, which makes them compatible with a wide array of telecommunications equipment. Their interoperability means that businesses can integrate these codecs into existing networks without significant disruptions.

Security is another prominent characteristic of the Nortel 2212 and 2211. With built-in encryption protocols, these devices ensure that voice and video communications remain secure from potential eavesdropping or unauthorized access.

In summary, the Nortel 2212 and 2211 play crucial roles in modern telecommunications, offering robust features like scalability, advanced compression, compatibility, and security. Their legacy continues to influence the development of communication technologies and practices in enterprises around the globe, even as newer systems emerge in the fast-evolving telecom landscape.
