Mounting the VisiChart
Direct View – When mounting the VisiChart directly in front of the patient, the center of
the monitor should be approximately 54” off the floor and centered in front of the patient
sitting in the exam chair. Recommended minimum direct view distance from patient is 3
meters. (Approximately 10 feet)
Mirrored View – When mounting the VisiChart behind the patient and using a mirror to
increase the total refraction distance, the center of the VisiChart should be located 78”
off the floor and 18” from the center of the chair, opposite the stand, so that the near-rod
does not interfere with the image presented in the mirror.
Electrical: It is recommended that a standard electrical outlet is installed behind the
VisiChart for best appearance, however the VisiChart can be plugged into any outlet
within five feet of the mounting location.
Remote Control Sensor: Plug the USB connector into any USB port on the side of the
VisiChart. Attach the sensor to the VisiChart with the enclosed Velcro pad to any
location facing into the exam room. Bundle and conceal the cable behind the VisiChart.
Note: The use of fluorescent lighting in the exam room will decrease the sensitivity of
the remote control. Incandescent lighting during VisiChart use is recommended.

which attach the table mount base. (Figure 1)
