Operation Manual AI Turbo S2
Page 16 of 69
1) Slow beep – the function is on
2) Fast beep – the signal is at least 5 dB higher than the lowest level seen
3) Solid – the signal is higher and at the highest level seen so far
Note that the peak-o-matic method does not indicate a lock. It allows you to peak the azimuth and
elevation even before a peak is obtained.
In both methods to fully peak the dish, you must move it in one direction until the signal is found,
and continue moving it until you move past the peak, then move back to the solid tone.
Shutdown Timer
The unit can be set to automatically shut off after 5, 10, or 15 minutes with no buttons being
pressed. This timeout can be disabled by setting the option to “none”.
Frequency Deviation
If you select Freq Dev = YES, the bottom line of the Run Screen display will be replaced with an
estimate of the frequency deviation or drift of the LNB. The AI Turbo S2 is capable of locking
onto a signal up to
±
10 MHz from the frequency defined for the transponder. A frequency
deviation of more than 2 MHz (2000 kHz) may indicate a problem with the LNB. High or low
temperatures will cause an LNB to drift and an LNB that works in normal weather with a
significant drift may fail to work in hot or cold weather due to the additional drift. Please note that
the Frequency Deviation feature will only work while you are receiving a LOCK on a satellite.
IRD Calc
As mentioned under “Signal Quality” above, Dish Network has an old IRD quality scale from 0 to
125 and a newer scale with much lower values (approximately 0 to 85). Use this option to select
which scale to use. The default is “New”.
PoP Delay
If you notice transponder results missing from the PoP Scan reports, you may need to introduce a
delay into the Proof of Performance scan. The value entered in this field is the number of
samples taken if a LOCK isn’t obtained. The unit takes 3 samples per second. If 0 is entered in
this field, the PoP Scan will operate normally without any delay. You may experiment with 5, 10,
15, or other values.
