The wff unit a wff unit consists of a hand-held transmitter control, a receiver/amplifier motor driver unit, and a power cable. To control a lens, a lens drive motor and motor cable are required. To start and stop a camera a remote control, or “run/stop” cable is required. The transmitter the transm...

Transmitter controls control knob : each transmitter has one main control knob, either a rotary knob or a linear slider. Once the lens drive motor has been calibrated to the lens at the receiver/amplifier, end-to-end travel of the knob moves the lens through the range set during calibration. The tra...
Troubleshooting i cannot get the receiver/amplifier to receive the signal from the transmitter (receiver/amp led stays red or flickers between red and green). There are several possible causes for this: • the calibration switch on the receiver is not in the operate (center) position. The led blinks ...
Transmitter indicators power led: the red/green power led has four modes of operation: green : unit on and transmitting, battery voltage ok. Flashing green : the unit has not been used for more than 15 minutes, so the rf transmitter has been turned off to save power. Changing any control or moving t...
Other things to know interference from video transmitters: uhf video transmitters, such as the modulus 2000 or 3000, tend to broadcast on other frequencies than the intended frequency. This can block the signal from reaching the receiver/amplifier. There are several things you can do to prevent this...
Pg. 10 the calibration knobs still set the ends of lens travel, but the calibration is slightly different. The calibration toggle switch has no effect and should be set in the middle position. Simply move the remote pot control all the way to one end of its travel. At this point, one of the calibrat...
Either one may be used for connection to an external 11 to 17vdc power source. If two wff’s are being used and only one power source exists, plug the second receiver/amplifier’s cable into the unused power connector on the first one. Pin 1 is positive, pin 2 is negative. Data in connector: this 3-pi...
Wff calibration procedure receiver/amplifier led status led: this red/green has three modes of operation: red: the unit is on but not receiving a signal from the transmitter green: the unit is on and receiving a signal from the transmitter flashing red/green: in calibration mode (the toggle switch i...
