If it is necessary to reverse the table direction, remove power supply from the (C) bottom, and fit it onto the opposite side.
ASSEMBLY
3 Connect (F) to the table outlet and the power supply. Coil up the surplus cord, put it in the cover, and attach the cover. To attach the tabletop to the instrument table AIT-11, IT-1:
Use the four 8 - 24mm bolts with locking washers. 1 Raise the table-top to allow the bolts to pass through the mounting flange. 2 Place the table-top on the mounting flange of the instrument table and screw the bolts into the mounting bracket. The controls of the power supply should face the practitioner. Tighten the bolts securely with the supplied wrench (S) To attach the unit model table-top to the Ophthalmic Unit (C'):
Washer
1 Peel off the tape which secures the plastic washer to the mounting bracket's shaft. 2 Insert the shaft of the mounting bracket into the hole of the arm on the ophthalmic unit. The plastic washer should be between the mounting bracket and the arm. Note:
The power supply is attached to the left side of the unit top (practitioner's view). If the ophthalmic stand is located to the left of the ophthalmic chair, the power

supply must be relocated to the right side of the unit top, to prevent interference with the arm. For a left-hand configuration, remove the four wood screws which attach the power supply to the unit top, re-position the power supply in a similar position to the right side of the unit top, and re-attach the power supply with the four screws.
2.1.3
Mounting the Chin Rest (E) 1 Remove the four screws which are attached to the chin rest mounting plate with the Philips screwdriver (R).
Chin Rest cord Chin Rest mounting plate
2 Place the chin rest cord in the gap between the chin rest mounting plate and the chin rest assembly. While making sure that the cord is not being pinched by the mounting plate, tighten the previously removed screws again. Screw
