place their chin on the chinrest comfortably.
4 Let the patient place their chin on the chinrest and forehead against the forehead rest.
5 By pressing the or buttons of the main body section of the instrument, adjust the
height of the chinrest so that the patient's eye becomes level with the height mark on the
chinrest support.
Make sure the patient's face is placed correctly on the chinrest, with the forehead
correctly against the forehead rest.
The chinrest moves up/down while the button or button is pressed.
The chinrest stops if the applied load exceeds the specified weight. If the chinrest
does not work even after removing the chin from it, it may be at fault. Turn OFF the

If the applied load exceeds the specified weight, the chinrest may not work. Advise
the patient not to push down on the chinrest more than necessary.
If the patient's head is placed in the center of the chinrest, measurement may be
disabled with a limit message. Make sure the patient's head is placed correctly.
For details about the limit message, see "Limit message" on page 44.
