Mounting and placement
At longer distances it is possible to find dead spots. Moving the FREE
X
WIRE
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
FREE
X
WIRE. Do not mount metallic labels on the units.
When wearing FREE
X
WIREs, mount them outside your clothing and away from your
body. And, of course, watch out for metal objects on or near you.
Transmitter FW9T units may be mounted close together. FW9T units will trigger
FW8R units at a distance greater than 3 ft (1m) up to the maximum range.
These are the maximum ranges which may be possible under optimum conditions
(vertical antennas, no metal nearby, no nearby radio stations or interference, about
5’ above open field):
Transmitter Receiver HI Range* NORM Range (TTL)
FW9T FW8R 1000’ (300m) 500’ (150m)
FW9T FW7Q 600’ (175m) 300’ (90m)
FW10, as a transmitter or receiver, operates at approximately 1/2 of the distances above.
Notes:
* HI range is not recommended for pre-flash systems (digital TTL). HI range can
be used for flash sync, wireless shutter release, or for non pre-flash TTL control
(mostly film cameras). HI range for FW7Q is set via the QF5d panel.
Interference
Do lot locate FREE
X
WIRE receivers directly on studio flash power packs or other
equipment that generate radio frequency interference, such as most heavy machin-
ery, 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.
The enemies of radio signals are metal objects, concrete, and water. Mount
FREE
X
WIREs away from metal objects when possible. Of course, you may be
mounting FREE
X
WIRE on light stands and brackets, and they generally have a
slight affect on range.
If you cannot remove FREE
X
WIRE receivers from the area of interference:
Close or partly close the receiver (only!) antennas which will decrease inter-
ference. Set FW8R RANGE switch to NORM. Be aware that these measures
will necessarily decrease range as well as cut interference.
Appendices
Accessories may be changed or added periodically. Please consult you dealer
or the Quantum Web page (www.qtm.com) for the latest models available.
