34 MTM800 Enhanced Mobile Terminal Installation Manual INSTALLATION
Installation Procedure
1. Select either the transmission hump or an open underneath portion of the dash to mount your 
terminal (see Figure 7). When mounting the trunnion on the transmission hump, be careful 
that the transmission housing is not affected.
2. Use the trunnion mounting bracket as a template, to mark the hole positions on the mounting 
surface. Use the innermost three holes for a curved mounting surface, such as the 
transmission hump, and the three outermost holes for a flat surface such as under the dash.
3. Centre-punch the spots you marked and use a 4 mm (5/32-inch) bit to drill a hole at each 
location.
4. Secure the trunnion mounting bracket to the mounting surface with the three self-tapping 
screws provided. (See Figure 7.)
5. Slide the terminal into the trunnion. Secure the terminal with the two wing screws provided.
