(Note): SmartKom stores the configuration chosen by the user: channels, input power supply, programmed output voltage.
Please Note; if the user performs a channel search (long press on the source or on the SmartKom device), the configuration will be ove-
ridden by the SmartKom, according to the search algorithm, discarding the user's changes.
Every time a channel scan is done, the unit will discard the existing configuration. Notice that the algorithm search is optimized and go-
verns three input preamplifiers individually, and automatically makes its decisions about the power control of the antenna or antennas
to find the best signal. Therefore, it is recommended to combine the SmartKom with High Dynamic Range Antennas (Such as Televes'
Ellipse or DAT LR series of high performance antennas) for search optimization in any reception scenario

9. Scroll to open screen of channel balancing: When the channel adjust visualization screen is open, the user can double check
the final result and fine tune if needed.
Figure 11: Channel adjust visualization screen
Figure 12: Channel adjust visualization screen example. Fine tune channels 14 (-3dB) and 36(+2dB).
(Note): If a programmed channel with a level lower than the SCHEDULED OUTPUT LEVEL is shown on the channel visualization screen,
it is most likely that its input level to the SmartKom is less than the input threshold level (-20 dBmV). If the user makes the decision to
include it in the channel list manually and makes an adjustment, SmartKom would not be able to adjust it to the scheduled output level
and it would be displayed with a lower level.
Such a channel would not be displayed after the user performs an automatic channel search (search and balance button on the Smar-
tKom or on the power supply), since it would be discarded by the search and balance algorithm.
In short, once the adjustment and balancing of the unit is completed, any channels that appear in the adjustment screen with a level less
than the programmed output level, are indicative of being below the input level required by the unit, and its operation can be potentially
marginal. On those weaker channels the user can try additional manual tuning to improve performance or try to optimize the antenna
aiming. (adjust antenna left to right and/or up/down)
