Operating instructions
Checking the signal strength
A signal strength report is automatically displayed on the hand unit LED display
after a channel check. To check the signal strength, press the channel button and
the current channel will be displayed, followed by the signal strength report,
which is shown in the form of two numbers, h0-9 (signal being received by the
hand unit) and then r0-9 (signal being received by the receiver)
We recommend that you try not to use the unit if the signal is below 2 as this
could cause undesired operation.
This is useful if you are operating in the upper limit of the systems range, you can
use these two values to determine which unit needs adjusting to gain better
signal.

Lens Calibration and Direction Changing
To change the direction of the motor in relation to the control knob, press the DIR
button on the controller. This will toggle the direction between C.d (clockwise
direction) and A.d (anti clockwise.) Please bear in mind that the direction the lens
moves in relation to the knob will change depending on the mounting of the
motor, the side the motor is on and which way the motor is facing. Also please
note that when changing the direction, the A/B limits if set will also change, to
take into account the new direction of travel.
When the direction is changed, the marks on the marking ring will reverse, so if
you mark a lens up and then change direction, the marks will no longer line up.
Please also note, as the system calibrates torque as well as limits, if the motor is
ever hand calibrated (stopping the motor spinning by hand to simulate motor
end stops) the system is essentially calibrating to zero extra torque, as the gear is
spinning in free space. This will make the motor appear very weak and easy to
stop. This is normal and is a sign that the auto torque calibration is working prop-
erly.
As with any remote or manual follow focus, some lenses and cameras will require
long lens supports, such as CP.2 lenses mounted via the EF mount on Canon
DSLRs. Please ensure that the lens has sucient support and is tight in the mount.
If the lens can rotate slightly in the mount then this can cause repeatability issues
with stops. It is especially important to help the lens stay in the right orientation
with EF mounts. The RED and C500 EF mounts with their ange clamps solve this
problem. In most other situations, a long lens support is necessary.
