ASSEMBLY PROCEDURE ASSEMBLING THE INSTRUMENT BODY WARNING
To avoid electric shock, be sure to unplug the power cable before assembling. Also, do not plug the power cable before assembling.
CAUTION
To prevent the instrument from falling and to avoid injury, do not install the instrument on an unstable place, including a slope.
CAUTION
To avoid injury during carrying, be sure to hold the instrument body at the bottom with two persons. Carrying by one person may cause backache or injury by falling. Holding at areas other than the bottom may also cause pinching fingers and injury, as well as falling, thereby causing damage to the instrument.
NOTE
Since the upper part and lower part of the instrument body are merely connected with the power cable, take them out together so they do not separate from each other.
1 Take out the instrument body (1) from the container and put it on the table. 2 Slightly raise the omni-directional joystick, and pull out the cushion from the lower part of the base in the arrow direction.

2 Mount the TV camera so the lens positioning hole matches the pin of the TV relay lens (2).
3 Turn the lens fixing ring in the arrow direction and fasten it.
16 ASSEMBLY PROCEDURE
CONFIRMATION AFTER ASSEMBLING
1 Slide the base to the left, as viewed from the operator side, and make sure that the primary voltage coincides with the voltage as set by voltage selector.
2 Make sure that the input voltage is within the range ±10% of the rated voltage. If the input voltage exceeds the range, use a constant-voltage power supply (marketed: 400VA up).
3 Loosen the base locking knob, and move the omni-directional joystick to confirm that it moves smoothly. 1) Right-left movement 2) Back-forth movement 3) Up-down movement
Just after being unpacked, the right-left movement may be uneven. If so, move the joystick with force to its limits in all directions.
