How to Mount your display ... continued

1. Suspension Mounting

Suspension  mount your EasyReader display in a clean, dry  environment.

The mounting screws you use should have a diameter between 3.2 and 3.8 mm and should
be suitable for the supporting material.  You may need to use screw  plugs or other screw
accessories, if the  material  is not suitable to take screws directly.

Mount the brackets first, then fit the display to the brackets.

Route cables neatly away from the display. If the cables may become damaged in the
environment, protect them with suitable conduit or trunking.
