a button on the unit until it begins transmitting. Transmission is indicated by the illumination of a red LED located
above the button panel cover.
Physical Description
NOTE
CRESTRON does not recommend designing large button caps for single functions. Depressing
the center of a large button cap can cause the unit to transmit incorrectly which may result in
the control system misinterpreting the user's intent. Therefore, design large button caps for
dual functions, such as a volume up/volume down rocker-type button.
CNRFHT and CNIRHT electronic hardware is housed in a slim, high-impact molded ABS black plastic enclosure
(refer to figure 2). A 30-button array on the printed circuit board is covered by a customized button panel. All
button panels include custom engraving, colored button caps, choice of button configurations, and panel finishes.
Small and large button caps are available. A small button cap covers one button. A large button cap covers two
buttons. Refer to the latest version of the CRESNET II Engraving Worksheet for CNRFHT and CNIRHT (Doc. 5344)
to design a unique button panel. Omission of unused buttons is standard. A red LED is located above the button
panel cover.

Aside from the diversity in button panel configuration, the only external difference between CNRFHT and CNIRHT is
the type of plastic material at the pointing end of each unit. CNRFHT has a black plastic cover with a tuning hole
(refer to figure 1) and CNIRHT has a ruby-colored IR signal filter.
