Description
Functional Description
The CNIRHT-MM is a 30 function, hand-held infrared (IR) transmitter
designed to work with the CEN-TVAV and/or CN-TVAV. By setting an
IR transmitter identification (ID) code in the CNIRHT-MM and using the
keypad buttons, any television or audio-visual (TV/AV) device attached
to the CEN/CN-TVAV may be controlled remotely. The functions of the
individual buttons are determined by the CEN/CN-TVAV and/or the
Crestron remote control system (herein referred to as the Cresnet system)

program.
To prevent interference from fluorescent lighting and most standard IR
frequencies, the CNIRHT-MM operates at 455 kilohertz (kHz). The
CNIRHT-MM must have an unobstructed line-of-sight to the CEN/CN-
TVAV being controlled. A light-emitting diode (LED) on the front of the
CNIRHT-MM indicates IR transmission when any keypad button is
pressed, is used to display the IR transmitter ID code that is set into the
unit, and flashes continuously when the CNIRHT-MM battery voltage is
low.
Physical Description
The CNIRHT-MM, shown on the next page, is housed in a slim, high-
impact ABS plastic black enclosure. The front contains one LED and 30
keypad buttons. At the rear of the unit is the battery compartment that
contains one 9-volt alkaline battery (included) and a sensor (photo
transistor) that is used to set the IR transmitter ID code.
