Figure 50: Terminal into Key Locked Mount Trunnion (RLN4779_)
3 Select either the transmission hump or an open underneath portion of the dash to mount your
terminal (see the following figure). When mounting the trunnion on the transmission hump, be
careful that the transmission housing is not affected.
4 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.
5 Centre-punch the spots you marked and use a 4 mm (5/32-inch) bit to drill a hole at each
location.
6 Secure the trunnion mounting bracket to the mounting surface with the three self-tapping screws
provided (see the following figure).
7 Slide the terminal into the trunnion. Secure the terminal with the two wing screws provided.
NOTICE: The keypad labeling of the control head may vary according to the specific
customer/country concerns.
8 Ground the radio housing to the nearest vehicle chassis ground point, which can be done by
removing the paint from the trunnion where the radio and vehicle chassis touches the trunnion,
or use a short cable with ring lugs in both end and connect this to chassis under the wing screw.
