ST-TUNE and STI-TUNE Symbols Input Descriptions (continued)
INPUT(S) FUNCTION(S)
This analog signal is a number that sets WX frequency. Valid
weather radio numbers are 16240d through 16255d. The number has
an implied decimal point 2 digits from the end and must be sent in
this format. For example, to go to 162.40, the analog number to be
sent is 16240d. Valid WX station increments are by 1, such as
162.41, 162.42. NOTE: If not in the WX mode, the unit will not go
into WX mode when this signal is received on this line. The signal will
set that value for the next time the unit is put into WX mode.
TV-Station This analog signal is a number that sets the TV station (channel).
Valid TV stations are different depending on the mode. (Refer to the
"TV Tuner Specifications" in the "Leading Specifications" section that
begins on page 7). Channel numbers are incremented by 1.

NOTE: All outputs listed in the following table require DIGITAL signals unless
noted otherwise.

Sig-Strength This 8-step analog signal is a number indicating how strong the
station is being received. The steps are decimal 0, 8191, 16382,
24573, 32764, 40955, 49146, 57337 or hexadecimal 0, 1FFF, 3FFE,
5FFD, 7FFC, 9FFB, BFFA, DFF9. This signal is active only during the
FM mode. NOTE: Best SRCH function recognition is achieved with a
signal strength of 24573 (5FFD) or above for low-sensitivity or 40955
(9FFB) or above for high-sensitivity.
These four analog numbers correspond to the current state each
band of the unit.
This is an interlocked group of signals. The signal that is high is the
current mode of the unit.
This is an interlocked group of signals. The signal that is high is the
current band of the unit.
These signals are high as long as the UP or DOWN button on the
front panel is being pressed and held.
This is an interlocked group of signals. The signal that is high is the
current mode of the unit.
ST-TUNE ONLY - This is an interlocked group of signals. When the
SAP mode is on (TV mode only), SAP-ON-F is high. The LED on the
front panel indicates if SAP is actually being received.
