OPERATION
As Wireless Flash Transceiver
Install two AAA batteries into each Cactus V5 transceiver. Ensure
that all plastic battery wrapping is removed and batteries are
installed in the correct polarity.
Note: Alkaline batteries are recommended. Rechargeable
batteries also work but operation time may be reduced.
Set the V5 transceivers to the correct mode (Transmitter to "TX",
Receiver to "RX"). This will automatically power on the
transceivers.
Connect the receiver (RX) to the light source:
Portable Flash
Studio Strobe
Set both TX and RX to the same channel using the Channel Dial.
On TX, press the Test button. The status LED of both TX and RX
should blink in GREEN simultaneously.
Attach TX to the camera’s hot shoe. If your camera does not have
a hot shoe, connect TX to the camera using a PC sync cable
(CA-100).
Press the camera’s shutter release button.

Connect the hot shoe of the external flash to female hot shoe
slot of RX, or use the PC sync cable to connect RX to the flash’s
PC sync port.
Connect RX to your strobe using a 3.5mm plug cable (CA-350) or
with a 6.35mm adapter (PA-635), according to your strobe’s port
size.
FREQUENCY SELF-TUNE (FST)
A common issue with flash triggering systems is the unintentional
frequency shift in relation to temperature change. This results in high
failure rate when exposed to extreme weather conditions. Frequency
Self-Tune (FST) is a new exclusive feature of V5 that minimizes the
likelihood of misfires to ensure reliable performance.
The concept behind FST is simple – every V5 transceiver is equipped
with a chipset that records the last functioning frequency (i.e. the
frequency level at which V5 works) at different temperature levels.
When the V5 transceiver is exposed to extreme conditions, it will
self-calibrate to this last working frequency after each firing.
To take full advantage of this new feature, it is advised that a “test
firing” be done before taking the actual shot. This will ensure that the
V5 transceiver in either Transmitter or Receiver mode will be
calibrated to a functioning frequency, and that important and
stunning photographs will not be missed!
FST is especially useful when V5 is exposed to the following extreme
conditions:
when operating temperature is <-5°C or >+30°C (<23°F or >86°F);
when there is a sudden temperature change of larger than 20°C
(68°F) or more.

For sudden temperature changes larger than 20°C (68°F), it is highly
advised that a series of test firings be done to ensure that V5 is tuned
to a functioning frequency. It is suggested that a five-minute interval
or about 5-10 test firings be allowed for V5 to adjust to the new
temperature.
