7. Installation
The ACP-900 should be installed according to the following procedures:
1. If using a wall mount, it is best to locate a wall stud to support the weight of
instrument.
2. Determine the refracting distance (form the patient’s eye to the screen) and
install the projection screen.
3. Position the instrument at the same distance from the screen to the patient
within the range between 2m and 7m. To obtain longer refracting distances in
small rooms, a mirror or systems of mirrors can be used. In this case, a high
quality front surface mirror is required.
