Mounting on surface (of panel or wall) 
Refer to Figure 2-10 and follow the procedure in Table 2-9 to mount your recorder on a surface (panel or 
wall).  
 
You must supply three (3) screws for attaching the mounting hardware (brackets and support 
hook) to panel or wall. 
 
Table 2-9 Mounting flush on a surface (of panel or wall) 
 
Using two flat-head 10-32 x 1/4-inch screws supplied with the recorder, fasten the support 
hook into the recess at the back of the recorder case as shown in Figure 2-10. 
Using 1/4-20 x 1/2-inch hex screws and lockwashers, attach a mounting bracket to each side 
of the case. Leave the screws slightly loose so as to permit some adjustments of the brackets. 
On the panel mark the locations for the three holes as shown by the hole pattern in Figure 
2-10. 
Using a drill of appropriate size for user-supplied screws, drill a hole in the front of the panel for 
the eye of the support hook. 
Insert the screws for the support hook into the panel, allowing the screw head to protrude 
approximately 5/16-inch. 
Hang the recorder support hook on the screw. Make sure that the locations for the other two 
holes (marked in step three) are correct. If not, make sure that the recorder is aligned vertically 
and use the brackets as templates to mark the proper locations. 
Remove the recorder from the panel and drill the other two holes. 
Hang the recorder on the screw by the support hook and insert the other two user-supplied 
screws through the brackets into the panel. Tighten the two hex screws that attach the 
brackets to the case.
