sidetone; they might hear their own voice in the headset as they speak, and it might sound harsh and thin. Following the steps outlined in the document, Audio Settings Guide for the CA12CD‐S, (provided with the CA12CD‐S and available online) should help the user avoid this problem. The general procedure for avoiding sidetone problems is to avoid unnecessarily‐high talk‐volume levels and to keep the sidetone controls on the host equipment—if present—set to their minimum positions.
Range and User Density Range can be maximized by taking the following steps: Maximizing the amount of separation between the CA12CD‐Ss Placing the CA12CD‐Ss so that they are separated by items such as cubicle walls and furniture Turning off all unused bases and removing the batteries from the unused remotes Insuring that no other equipment is operating in the same frequency band as the CA12CD‐S; interference may come from systems well outside the coverage area, as the range for interference is great
Encryption The protection against deliberate eavesdropping is through user authentication and 64‐bit true digital encryption of voice data according to the standard algorithm of EN 300 175‐7. A description of the public portion of this encryption algorithm is available through the website of the European Telecommunications Standards Institute (ETSI) at www.etsi.org.
