Step 1. Prepare instrument 

To prepare the instrument for mounting, remove the handle, the mounting ears, and both rear feet. The following 

information outlines this process. 

1.  

Remove the handle

 —The handle serves as an adjustable tilt-bail. Adjust its position by gently pulling it 

away from the sides of the instrument case and swinging it up or down. To remove the handle, swing the 

handle below the bottom surface of the case and back until the orientation arrows on the handles line up 

with the orientation arrows on the mounting ears (refer to Figure 1). With the arrows lined up, pull the ends 

of the handle away from the case. 

2.  

Remove mounting ears.

 

•  

Remove the screw that secures each mounting ear.  

•  

Pull down and out to remove each ear.

NOTE  

Do not re-install the feet mounting screws. Save all parts removed for future bench top use of 
the instrument.
