Operational advice
•
For best performance
, select a channel that has the least amount
of interference. While the transmitter is turned OFF, turn on the
video headset and look at the screen as you check each channel.
Clear channels will have a consistent static background. Channels with
interference will have horizontal static lines.
•
Always perform a range test before flying
. This includes AV and RC
controls. Some RC receivers can be affected by the proximity of other
electronic devices particularly the AV TX.
• Try to space out your components as much as possible to avoid interference
to your RC control range (keep stuff away from RX)
• Until experienced, practice flying in a familiar area to avoid becoming
disorientated.
•
Due to antenna characteristics, there is a “null” in line with antenna direction.
You may experience excessive video breakup when flying overhead
• 5.8GHz signal strength drops off very fast, stay safely within solid AV range.
•
For maximum distance
it is very important that a clear line of sight exists
between the transmitter and the video headset. 2 of the worst causes of
interference are human bodies and reinforced concrete.
• Place your TX antenna in open area in a vertical orientation
•
Multipathing
(reflections off buildings/ tall objects) causes signal
cancellation and result in broken video. Fly in open areas away from
buildings or other tall structures (i.e. barns, hills).
