1. Introduction
All Recall Focus Duo is a brand new remote wireless device which controls focus and zoom on DSLR
cameras. It is especially suitable when using jibs, sliders and steadicams. Motor torque of 16 kg,
extended range of operation of 320°, and the adjustable gear ring allow precise control of focus and
zoom on any lens. For precise control of lenses with range smaller than 320°, in/out range calibration
is available.
Its matchless option of memorizing four different focus or zoom positions, allows automatic recall at
any point of shooting with simplistic memory buttons located on the ergonomic control panel. The
replay speed between the stored positions is also adjustable. The system allows remote recording and
trigger command for Cannon DSLRs. For night working mode, there is a practical glowing ring.

3. Mounting the All Recall Focus Duo:
3.1 To mount All Recall Focus Duo properly, please follow the steps:
1. Attach the rods on the camera plate
2. Mount your camera on the camera plate
3. Mount the receiver on the rods (it should be turned to the right, as shown on the picture
above)
4. Mount the IR sensor for REC/trigger command on the left rod so that it stand right in front of
the sensor of your camera, as it is shown in the picture.
5. Mount the Motor 2 (zoom motor) on the rights rod (see the picture above)
6. Mount the Motor 1 (focus motor) on the left rod (see the picture above)
7. Connect the motors with the receiver
8. Connect the IR sensor with the receiver
9. Mount the adjustable gear rings on the focus and zoom gears on your lens. (Pay attention that
the rest of the ring is turned in the opposite direction from the motor driver)
10. Make In/Out range calibration (See the charter In/out range calibration)
11. Connect focus and zoom gears to your lens’ gears. Pay attention: Motor gear spring must be
tensed.
For larger lens, when you need a longer rod to mount the focus motor gear, you can attach one
rod to another, like shown in the picture:

3.3 In/Out range calibration
All Recall zoom and focus motor gears have an extended range of 320°. If your camera lens has
smaller focus/zoom gear range, it is recommended that you make in/out range calibration, to protect
your lens gears from being forced to move beyond their physical range.
To make range calibration, please follow the steps:
1. Keep the focus /zoom gears separated from the lens
2. Turn the motor 1 (focus) potentiometer to
maximum position
3. Turn the motor 2 (zoom) potentiometer to
maximum position
4. Shortly press memory buttons 1 and 3
simultaneously. (Focus/zoom Motors now have full
operation range of 320°)
5. Now turn the motor 1 potentiometer to
minimum position and pay attention in which
direction All Recall focus gear is turning.
6. Turn the motor 2 potentiometer to minimum
position and pay attention in which direction All
Recall zoom gear is turning.

7. Turn your lens’ focus gear in opposite direction
from the motion of All Recall focus gear until it has
reached the maximum position.
8. Turn your lens’ zoom gear in opposite direction
from the motion of All Recall zoom gear until it has
reached the maximum position.
9. Connect motor 1 gear to the lens
gear.
10. Connect motor 2 gear to the lens
gear.
Pay attention that motor
gear springs are tensed!
11. Turn the focus and zoom potentiometers slowly until you have reached the range-end position on
your camera lens. Then stop.
12. Shortly press memory buttons 1 and 3 simultaneously.
The range of focus and zoom motors is compatible to your
lens range and you can move it without fear of damaging
the lens.
IMPORTANT! You need to repeat this procedure any time
you reattach the focus and zoom gears to the lens and also
when you change the lens. You do not need to repeat the
procedure if you have turned the focus controller off for
some time without separating the gear from the lens. When
the transmitter is turned off, all the settings are kept in
memory.

Possible problem: After you have made range calibration one of the motors-gears does not spin.
Solution: When this happens, it means that you have probably changed motor gear polarity settings.
To return the motor gear polarity to default, please follow the instructions in the charter 3.4.1 Return
to default motor polarity settings.
If the motor still does not work, after you have changed the polarity, please contact our service.
3.4 Motor gear polarity
Motor-gear polarity is set to default.
If you would like to change the direction of motor-gears you should follow the steps:
Motor 1 polarity change:
1. Keep the transmitter off.
2. Press and hold the button 3.
3. While holding that button 3, switch the transmitter on.
4. Release the button 3.
5. Motor 1 polarity has been changed.
Motor 2 polarity change:
1. Keep the transmitter off.
2. Press and hold the buttons 1 and 2 together.
3. While holding the buttons 1 and 2 switch the transmitter on.
4. Release the buttons 1 and 2.
5. Motor 2 polarity has been changed.
IMPORTANT!
When the polarity is changed, the in/out range calibration must be done the opposite way, meaning that
minimum points should be changed with maximum positions and vice versa!
3.4.1 Return to default motor polarity settings:
To return to default motor-gear polarity settings, please follow the steps:
Motor 1 polarity change:
6. Keep the transmitter off.
7. Press and hold the button 1.
8. While holding that button 1, switch the transmitter on.
9. Release the button 1.
10. Motor 1 polarity has been changed to default.
Motor 2 polarity change:
6. Keep the transmitter off.
7. Press and hold the buttons 2 and 3 together.
8. While holding the buttons 2 and 3 switch the transmitter on.
9. Release the buttons 2 and 3.
10. Motor 2 polarity has been changed to default.

3.5 Motor gear position adjustment:
The Focus motor gear can be adjusted in different positions to fit your lens. See the pictures.
4. Transmitter
After the power switch on the transmitter and receiver is turned ON, devices will start establishing
wireless communication and memory buttons on transmitter will flash.
When the memory buttons stop flashing, the light on REC button will continue to shine blue. Wireless
communication between transmitter and receiver is now established.
Antenna
It is recommended, after all equipment is installed, to turn antennas vertical on both devices.
Otherwise operating range may be decreased.

4.1 Changing focus
To move the focus gear on your camera lens, use the focus potentiometer at the bottom side of the
transmitter. Position and speed of focus change directly correspond to potentiometer movement.
4.2 Changing zoom
To move the zoom gear on your camera lens, use the zoom potentiometer on the right side of the
transmitter. Position and speed of zoom change directly correspond to potentiometer movement.
4.3 To check the status of transmitter’s
battery, please follow the steps:
1. Attach the digital voltmeter to the
transmitter as shown on the picture.
2. Read the battery voltage on the display.
If the voltage is under 10,0 batteries need to
be charged.
If the voltage is near 12,0 batteries are fully
charged.
4.4 Setting the night mode ring
To set the desirable light strength of night mode
Ring, please follow the steps:
1. Press the REC button, before you switch the
transmitter ON.
2. Keep the REC button pressed and switch the
transmitter ON.
3. The night mode ring will start pulsing.
4. When the ring has reached the desirable strength of
light, release the REC button.
5. Night mode ring is now set to desirable light strength.

5. Receiver
After All Recall Focus receiver is turned on with a power switch, device will go through a short self-
testing and signal and power LED indicators will flash twice. After that, both LED indicators will turn
on.
If the receiver fails to establish wireless communication, signal LED light will flash fast.
IMPORTANT! If you do not connect zoom and focus motors with transmitter, wireless communication
cannot be established.
5.1 To check the status of receiver’s
battery, please follow the steps:
1. Attach the digital voltmeter to the
receiver as shown on the picture.
2. Read the battery voltage on the
display.
If the voltage is under 10,0 batteries need
to be charged.
If the voltage is near 12,0 batteries are
fully charged.
