Troubleshooting
Frequently Asked Questions
Q. My picture is jerky, how can I solve this?
A. A jerky picture is an indication of poor Frame Rate. Put the system into Test Mode (see page 09 -
11) and check the Signal Level. Try adjusting the position of the antenna on both the Transmitter and
Receiver whilst another person monitors the Signal Level.
Q. How can I improve the Frame rate?
A. Poor Frame Rate is the result of a significant loss of data packets (a poor Packet Rate) from the
Transmitter. The Receiver is able to reconstruct the lost data packets but it has to make an intelligent
guess as to their value. Try adjusting the position of the antenna on both the Transmitter and Receiver
until the problem is resolved.
Q. I can never acheive a good Packet Rate, can I just leave it as is?
A. Sure. The Receiver has been designed to work with significant packet data loss without any serious
degradation to picture quality and never a loss of sound quality.
Q. Do the antennas need to point directly at each other?
A. Yes. The antennas must be pointed at each. They must also be in the same plane, so for example,
if the Transmitter Antenna is mounted vertically, the Receiver Antenna must also be mounted verti-
cally.
Q. Will trees and buildings reduce the range of the DigiSender® XD-2KM?
A. Yes, trees, buildings and any other objects that are inbetween the Transmitter Antenna and
Receiver Antenna will affect range. Ranges are typically between 200m and in excess of 2000m.
