The RC-7000CI remote control offers fully programmable capabilities integrating both standard key and LCD display key technology maximizing performance, configuration and ease of use. Infrared (IR) and radio frequency (RF) signals allow for integration into almost any application. Line of sight is not required in RF mode allowing more flexibility when walls and obstacles are a problem. Denon codes are pre-programmed for quick setup. The RC-7000CI is 2-way communication ready when used with the RC-7001RCI base station supporting Meta-Data when used with '08 series AVR receivers with RS-232C serial ports.
