Wall Mounting Instructions
WARNING: IT IS IMPORTANT TO SAFELY SECURE THE EQUIPMENT. UNSECURED EQUIPMENT COULD
POSSIBLY BECOME DISLODGED AND FALL, CAUSING INJURY TO EITHER THE PATIENT OR EXAMINER.
WARNING: CARE MUST BE TAKEN TO ARRANGE THE CABLES FOR THE ACCESSORIES SUCH THAT
THEY DO NOT PRESENT A TRIPPING HAZARD TO THE EXAMINER OR A DANGER TO THE PATIENT.
WARNING: POSITION THE CLEARCHART 4P ON THE WALL SO THAT IT IS NOT DIFFICULT TO OPERATE
THE DISCONNECTION DEVICE (PLUG).
Note: Make sure the position you choose to mount your ClearChart 4P is within the reach of a
power outlet.
Direct-Throw: Your ClearChart 4P must be positioned at patient eye level directly in front of the
patient. The minimum test distance is 6 feet (1.83 meters) with a maximum test distance of 24.6 feet
(7.5 meters). Refer to the Direct Throw illustration in this section.

testing distance when the room does not permit a direct-throw arrangement. Typically, your ClearChart
4P will be positioned higher than patient eye level so that the examiner will not interfere with the
patient’s view of the ClearChart 4P. Arrange the ClearChart 4P and mirror so that the ClearChart 4P
can be seen by the patient through the mirror.
1. Find an appropriate spot on the wall that will support the ClearChart 4, which will hang from the
VESA compliant Mounting Bracket. Ensure that the refraction distance meets the requirements
for either Direct Throw or Mirror Arrangement.
2. Level the supplied Wall Mount Bracket and mark the holes on the wall. The mount should be
installed in solid wood stud, brick or concrete wall.
3. Follow all installation instructions enclosed in the box with the mount.
4. Hang the ClearChart 4P by lining-up the holes on the back of the device with the four holes on
the mounting bracket. Secure the ClearChart 4P to the mounting bracket with the 4 screws
provided.
