BR Remote U4-J Operating Instructions

Heavier cameras can suffer from clutch 'bounce' at sudden stops because the tilt gears cannot be
'back-driven'. Loosening the clutch will allow the clutch to absorb this and give smooth stops.
Sometimes the camera needs to be balnced slightly forward. Not too much!
Pan, Tilt, Zoom & Focus
Operating the unit is intuitive from any of our controllers. This section should be read in conjunction
with the appropriate controller instructions.
Pan & Tilt is the main function of the head and is controlled with the joystick in a fully progressive
manner. There are 10 electronic 'gears' for each axis which are adjusted by the controller. There
is also a 'Turbo' function which puts the head into the highest speed whilst this command is active.
The head then returns to the previous speed.
All control directions can be reversed using the 'REVERSE' functions on the controllers. This
cycles the control direction of each axis through the 4 possible configurations. These settings are
stored in the head even when the unit is powered off. This means that inverted and upright heads
can be used together on the same controller with the directions all working in the same way.
Zoom drift can be nulled via the Joystick Controller. See controller instructions.
Preset Positions
Up to 8 preset positions can be stored and recalled. Each position includes, Pan, Tilt, Zoom and
Focus positions. These positions are absolute and saved during power off. They are not lost even
if the head is moved using the slipping clutches.
If the head does not reach the preset positio within 6-8 seconds it will time out and abort the move.
This can occur if an obstruction is met or the position is out of range.
A preset move can be aborted by operating the joystick or zoom rocker on the controller. Sending
another move will also abort the move and send it to the new postion.
