Remedy
1.
Reflections of the signal can sometimes affect the transmission quality.
Move the Video Transmitter or Receiver away just a few inches and this
should solve the problem.
2.
Change the channel settings (A to D) set on the Video Transmitter and the
Video Receiver.
1.
Is the same transmission channel (A to D) set on the Video Transmitter
and on the Video Receiver?
2.
Is the transmission distance too great? Reduce the distance between the
Video Transmitter and the Video Receiver. The range is up to 100 metres
line-of-sight, but walls and ceilings reduce it.
3.
Have you used the right cable?
1.
If you operate wireless headphones or a similar wireless transmitter on the
same frequency as your 433 MHz system, this can severely reduce its
range.
2.
Is the RX cable inserted into the VT30CT and glued over the infrared eye
of the unit that is being controlled?
1.
Wrong code set. Reset the code as described in section 11.
