International Communications Group (ICG) today announced upgrades to the Sigma7 retractor-reel handset. The phones will now feature a backlit keypad and LCD display for improved visibility and functionality in low-light conditions.  

Additional features include an improved noise-reduction microphone, speed dialing, last number redial, a louder ringer with provisions for an additional plug-in external ringer, and the addition of a mute feature for transmitted audio. The new Sigma7 BL also has an internal magnetic stripe reader to support credit card calling over various communications networks, including the Iridium network. A special functions key provides access to a programming menu and enhanced features such as flash transfer.  

"At ICG, we listen to the requirements of our customers and strive for constant improvement, setting high standards for our product performance and engineering," said Armin Jabs, president of ICG. "Upgrades to the Sigma7 handset will make this communications system even more convenient and user-friendly."  

The Sigma7 BL operates with a 2-Wire telephone line and can either be bulkhead-mounted or recessed in a drink rail. A data jack (RJ-11) option is available in the cradle to connect to a data modem, either via the telephone circuit or a separate circuit to allow for simultaneous data and telephone calls.  

The new backlit phone system operates with all models of ICG cabin CTUs and ICG Iridium systems, and existing installations can be upgraded with the new phones.
