WARNING

To avoid fire and electric shock in case of leakage, be sure to use a grounded receptacle. Do not connect to receptacles that are not grounded.

CAUTION

To avoid electric shock, remove the power plug from the receptacle before checking the power supply frequency.

Check the input voltage. Make sure that the input voltage is within ±10% of the rated voltage for the instrument. If the voltage has fluctuations that exceed the 10% range, use a commercially available voltage regulator or line conditioner. Use of the instrument with incorrect voltage may cause malfunction. Check the receptacle. The current capacity of 20A or more is necessary. Make sure that the power plug is fit to the receptacle. If not, contact an electrician to ground it. Check the operation of the joystick. Loosen the base fixing knob. Operate the joystick to make sure that it turns smoothly in all directions. • Right-and-left movement • Back-and-forth movement • Up-and-down movement

4 5 6

Check the inclination balance. Loosen the inclination brake knob and incline the optical unit to check the balance. The instrument has already been adjusted to keep its balance when shipped. If the instrument loses its balance, contact your dealer. Check the illumination lamp. Connect the power plug to a grounded outlet and turn on the power switch. Press the ON button and verify that light comes out the objective lens by placing your hand or a piece of paper in front of it. Check the Xenon lamp. When equipped with TV relay lens TL-270BC, turn the instrument on and set it at "photography" ( ). Select Photography and press the trigger button to verify that the xenon bulb flashes. Contact your dealer for other types of TV relay lenses, which are accessories.

Check the horizontal balance. Set the inclination unit to "horizontal" and the swing unit to "straight". Then, move the

instrument back and forth or right and left by using the joystick. If you release the joystick during movement, it may be returned to its original position. In such a case, make the necessary adjustments by referring to "ADJUSTMENT OF HORIZONTAL BALANCE" on page 31.

Check the table. Lock the wheels of the table.

30 CHECK AFTER ASSEMBLY

ADJUSTMENT OF HORIZONTAL BALANCE If the floor or the instrument table is not horizontally leveled, the base of the instrument may drift out of position. In this case it will be necessary to adjust the horizontal balance. The following steps indicate how to do it.

1 2 3 4

Set the inclination lever to "horizontal" and the swing lever to "straight". Move the instrument back and forth by using the joystick. When you release the joystick during movement, check if it is returned to its original position. If the joystick is returned, turn the adjuster under the base of the instrument to adjust the height. Keep the same height for both of right and left directions.

Also, adjust the height in the forward and backward directions. Keep the same height adjustment degree for both forward and backward directions.
