6-3 Mounting and removing the display unit
There are two mounting arrangements:
• Flush mounting requires a solid panel with
access behind for wiring and mounting
screws. After flush mounting, the Explorer 435
and Explorer 438 cannot be tilted or moved
after installation to reduce any unwanted
glare or reflections. Carefully select the best
viewing position before installation. This
would generally be in a shaded area.
