Crestron ST-TUNE Integrated AM/FM/TV Tuner
Operations Guide - DOC. 5833A Integrated AM/FM/TV Tuner: ST-TUNE •• 5
NET
This LED (yellow) indicates that the SIMPL program currently loaded in the control
system has a network device defined at the same NET ID code as the ST-TUNE. The
LED flashes when communication with the Cresnet system and the ST-TUNE is
occurring.
BAND INDICATORS AND DIGITAL DISPLAY
The AM, FM, WX (Weather Radio), or TV indicators contain four LEDs (red) to
display the active band of the ST-TUNE. The digital display shows the radio
frequency or TV channel being received.
RECEPTION INDICATORS
These three LEDs (red) indicate the reception status of the ST-TUNE. The LED
labeled SIG indicates the strength of the incoming FM signal, the steadier and
brighter the LED the stronger the signal. The MONO indicator illuminates when the
mono selector is activated while in the FM, WX or TV band and the SAP indicator
illuminates when the SAP selector is activated while in the TV band (regardless of
whether or not SAP information is being received).
NOTE: The SIG LED provides the most accurate indication of the incoming FM
signal after the ST-TUNE has reached optimum operating temperature
(approximately 10 minutes).
TUNING MODE INDICATORS
These three LEDs (red) indicate the tuning mode of the ST-TUNE. The LED labeled
PRE indicates that the preset mode (the preset functions are determined by the
control system program) is activated. The TUNE indicator illuminates when the
manual tuning mode is activated and SRCH indicates that search tuning is activated.
UP/DOWN CONTROL BUTTONS
During the PRE mode, the up or down control buttons cause the Cresnet control
system to perform a preset or pre-programmed function. If not programmed, these
buttons have no function during this mode. Refer to “Programming with SIMPL
Windows” on page 13 for further information. While in the TUNE mode, the up or
down buttons increment and decrement the radio or TV frequency by one step during
each press. If pressed and held, the ST-TUNE will rapidly tune up or down. If the
selected band supports the search tuning function, pressing either button during the
SRCH mode searches the radio or TV frequency range for the next strong incoming
signal.
NOTE: The SRCH mode performs most accurately after the ST-TUNE has reached
optimum operating temperature (approximately 10 minutes) and is receiving an
adequately strong signals. Refer to the Sense-High and Sense-Low entry of the
“ST-TUNE and STI-TUNE Symbol Input Descriptions” table on page 18 for further
information.
SELECTION BUTTONS
The selection buttons cycle the reception functions of the ST-TUNE. Repeatedly
pressing the BAND button cycles through the AM, FM, WX, and TV bands.
Pressing the MONO button toggles between the mono and stereo reception (for all
modes except AM in ST-TUNE, for all modes except AM and TV in international
version STI-TUNE) and the MODE button cycles through the preset, manual, or
search tuning modes.
