NOTE: DO NOT reposition the lap belt mounting  
location from the factory installation on the TRANS-  
PORT READY OPTION (TRRO).  
NOTE: Stabilize from the ground up. A stable base  
(seat) and footrest are the first steps to a stable  
pelvis. Also, the user should be lightly clothed for  
the initial adjustment.  
NOTE: A belt angle of 45o will usually provide the  
best stability and positioning. The belt will apply its  
pressure directly to the hips, usually allowing more  
force to be applied without discomfort.  
NOTE: The most desirable location for the mount-  
ing screws will be determined by the size of the  
client involved and the angle achieved by trying the  
various attachment points with the client seated  
comfortably in the wheelchair.
