    • notice
    • In the phase of rubber selection, do not attach the rubber yet !!!
    note: When selecting the thicker rubber, the head holder can be latched securely with less horizontal free–play. However, this causes hard latching and a customer might use the head holder with no latched, so that the head holder might drop from the cradle and a patient might be injured. So, try the different rubber in thickness to select the proper one.
    1. First place the two 4.0 mm rubbers (the thickest rubber) onto both edges of the head holder as shown.

      • The rubber must be placed with its tab facing out.

      • The thickness is printed on the rubber.

      • You have only to place the rubber onto the holder. You do not need to set it in an upright position when selecting the rubber.

      2. Notice Image

      • Do NOT press the head holder at high pressure when latching it. The plastic bolts for mounting the latch mechanism might be damaged.
    2. Insert it all the way into the cradle and press the head holder at proper pressure.

    3. Check if the head holder is latched on the cradle at the fist step of the latch mechanism. (The head holder does not need to be latched at the second step.)

      Check if the head holder has a small free–play in the horizontal direction.

    4. When the head holder is not latched (the rubber is too thick to install), repeat steps a to c using the second– thickest rubber (3.5mm).

      Even if the thinnest rubber (0.5mm) can not be used, cut the tab of the 0.5mm rubber.

    note: After adjustment, ask your customer to check the head holder free–play.
  3. Rubber Installation:
    1. Clean any dirt off the attaching surface of the rubbers using an alcohol as shown.
    2. Peel off a papers from the rubbers, then attach the rubbers on the head holder as shown. Hold the rubber a few seconds with your fingers to attach it securely onto the head holder.
      note: The rubber must be attached with its tab facing out.

    3. Latch the head holder to the cradle, then verify tha the head holder has a small free–play in the horizontal direction.
