INSTALLATION MTM5400 Mobile Terminal Installation Manual 33
Installation Procedure
1. Select either the transmission hump or an open underneath portion of the dash to mount your
terminal (see Figure 6). 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 6.)
5. Slide the terminal into the trunnion. Secure the terminal with the two w ing screws provided.
6. 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 unde r
wingscrew.
The keypad labelling of the control head may vary
according to the specific customer/country concerns.
