11.0 FreeXwire Performance Guide 
How to maximize performance, troubleshoot, and answer questions about Quantum’sFreeXwire Wireless Photo 
Control System. 
If for some reason we don’t have an answer in this guide, please email, fax, write or call Customer Service for further assistance. 
Good radio performance depends on several factors: The orientation of a radio and antenna, the presence of other radio signals 
which may interfere, and the presence of objects which may interfere. As the range increases, these issues become more 
important. At close range, performance is less critical. 
The following suggestions will maximize range and reliability of your FreeWire link: 
Orientation 
The ideal orientation is with all FreeXwire antennas opened 
vertically and all antennas parallel. If FreeWire is attached 
to a camera and you change from vertical to horizontal 
framing, you can easily swing the FreeXwire antenna back 
to vertical. 
When switching repeatedly from horizontal to vertical 
framing, you may set the TX antenna at 45° as shown. 
That will provide reasonable range without adjusting the 
antenna with every shot.

Mounting and placement 
The enemies of radio signals are metal objects, concrete, and water. Mount FreeXwire’s away from metal objects when possible.  
Of course, you may be mounting on light stands and brackets, and they generally have a slight affect on range. 
At longer ranges it is possible to find dead spots. Moving the FreeWire Remote unit a few inches in any direction can cure the 
problem. 
Do not use gaffers or duct tape which have metal threads imbedded, on any FreeWire. Do not mount metallic labels on the 
units. 
When wearing FreeWires, mount them outside your clothing and away from your body. And, or course, watch out for metal 
objects on you. 
Transmitter FW9T units may be mounted close together. FW9T units will trigger FW8R units from a distance of about 3 foot 
(1m) up to the maximum range. 
Interference 
Keep FreeXwire receivers away from flash units and generators that generate radio interfering signals. That is also true of most 
any heavy machinery, motors, and of course other transmitters.  Arenas, factories, and offices have other sources of radio 
“noise” which can include TV camera uplinks, walkie-talkies, radio and TV broadcast antennas, and cell phone repeaters. 
If you cannot remove FreeXwire receivers from interference, close the 
receiver
 antennas which will decrease interference, or 
set FW8R SEN switch to “lo”, however decrease the range as well.
