Calibration Steps

 

 

TIPS FOR CALIBRATION STEPS:

 

 

Navigation unit must be maintained in steady position, or calibration will not be accepted. A red hand will flash 
on screen if unit is not steady.

 

 

Level circle must be green, but ball does not need to be in exact center of circle.

 

 

Do not move to next position too quickly. Wait for double beep, then place in next position as shown on screen.

 

 

Displayed numbers are the percent errors from the nominal jig angles on each axis, and should be 4.0 or less.

 

 

If navigation unit does not proceed to next screen after several seconds, check that navigation unit and reference 
sensor are correctly attached to the bracket and press left button three times to repeat from first calibration step 
(Step 4).

 

 
 

 

STEP 4:

 

Angle unit away from you so that pelvic jig rests on table 
with navigation unit screen facing up. 

 
 
 
 
 

STEP 5:

 

Angle unit toward you so that reference sensor rests on 
table with navigation unit screen facing you. 

 
 
 

 

STEP 6:

  

Rest navigation unit on left side on table. 

 

 

 

STEP 7:

 

Angle unit away from you so that pelvic jig rests on table 
with navigation unit screen facing up. 

 
 
 
 
 

STEP 8:

 

Attach reference sensor to coupler on probe.  Verify that 
numbers are displayed on the screen by sliding the probe to 
different positions.
