3.2. Installation
To assure proper test conditions TCP-2000 Chart Panel should be mounted on the
wall perpendicularly to the patient’s line of sight. The distance from panel to
patient’s eye can be adjusted from 1.9 to 7 meters, depending on test room
conditions. There is possibility to change distance units from meters to feet (6,5 to
23,5 feet). For information on how to adjust the distance please refer to chapter 4.1.
Mounting instruction for TCP-2000 panel is presented below.
1. Each Chart Panel is supplied with wall mounting plate. Use three wall
screws (included in the package) to securely attach mounting plate to the wall.
2. Screw Chart Panel tightly to wall mounting plate using three screws.
