Personnel using this instrument should read and understand the operating instructions
manual before using the instrument. Interpretation of the results should be performed only
by appropriately trained eyecare professionals.
Open the shipping box by carefully cutting the packing tape securing the top flaps of the

roll of paper. Lift the instrument out of the remaining foam insert by grasping the
instrument at the two cutouts provided and set the instrument on a flat, stable surface.
Remove the plastic bag from the FDT Visual Field Instrument. Use of an adjustable height
chair and/or table is recommended when performing testing.
After you have unpacked the instrument and its components, confirm that you have
received the following items in good condition:
• Humphrey FDT Visual Field Instrument
• Calibration Cap (covering the Patient’s Eyepiece inside the Patient Visor)
• Patient Response Button
• Power Cord (appropriate for local operating voltage)
• Extra roll of paper
Note: Retain the shipping materials (box and packaging) in the event of shipping
damage or for return, if necessary, to an authorized service or distribution location at
any time in the future.
After unpacking the instrument, pull down the Paper Access Door (below the LCD display)
using the Finger Tabs on the sides of the door. Remove the foam shipping wedge

Paper Slot in the door. Failure to remove the shipping wedge will result in improper
operation of the printer.
