==Introduction==
<p>The step-by-step instructions in this guide are a general reference for installing the LED Display. If any details in this document are unclear, please contact your reseller for more information.</p>
{{Note|It is recommended to ask your reseller or licensed professional to install the LED Display.}}

==About the LED Display==
<p>ViewSonic Direct View LDM231-251 is designed to be installed on the wall only. However, the System Control Box can be mounted in three different ways.</p>

==Before Installing==
<p><i class='fas fa-exclamation-circle' style='font-size:24px'></i>&nbsp; Ensure there is no direct airflow from air conditioning or heating vents blowing on the display.</p>
<p><i class='fas fa-exclamation-circle' style='font-size:24px'></i>&nbsp; Avoid installing the LED Display in places with high humidity.</p>
<p><i class='fas fa-exclamation-circle' style='font-size:24px'></i>&nbsp; Due to high power usage, always use power cords specifically designed for this product.</p>
<p><i class='fas fa-exclamation-circle' style='font-size:24px'></i>&nbsp; Wood may split if holes are not pre-drilled before installing the Wall Mount Brackets.</p>
<p>&nbsp; Ensure that the wall can safely support 378 kg and the power outlet supplies enough voltage (max: 4124W; normal: 1443W).</p>
<p><i class='fas fa-exclamation-circle' style='font-size:24px'></i>&nbsp; Ensure the deviation of the wall surface is < 5 mm.</p>
<p><i class='fas fa-exclamation-circle' style='font-size:24px'></i>&nbsp; Wear protective gear, such as gloves and protective shoes, when handling the LED Display.</p>
==Standard Installation==
===Wall Mounting===
Eight Wall Mount Brackets are used for mounting the screen to the wall.
<ol>
  <li>
    <p>Ensure the wall area is an appropriate installation site.</p>
    <div class="res-img">[[File:LDM231-251 Spacing Standard.png|500px|alt=spacing instruction]]</div>
{{Note|
:*You can also install the Upper Wall Mount Brackets, hang the screen, and then install the Lower Wall Mount Brackets for a more precise fit.
:*Adjustment in floor clearance and ceiling height should be made according to the actual installation site.
}}
  </li>

  <li>
    <p>Using the illustration as shown below as a guide, mark at least eight mounting holes and pre-drill them.</p>
    <div class="res-img">[[File:LDM231-251 Hole Spacing Guide.png |500px|alt=Mounting Hole Spacing for the Wall Mount Brackets]]</div>
  </li>

  <li>Install the first Upper Wall Mount Bracket with the provided screws (M8 x 80 mm Expansion for masonry; wood screws for load bearing wood). 
  </li>

  <li>Repeat '''Step 2~3''', ensuring the second Upper Wall Mount Bracket is level with the first Upper Bracket.
{{Note|It is recommended to use a laser or torpedo level.}}
  </li>

  <li>
    <p>After mounting the first and second Upper Wall Mount Brackets to the wall, secure them with the Wall Mount Connector Plate using the six provided screws (PM6 x 10 mm).</p>
    <div class="res-img">[[File:LDM231-251 Installing Wall Mount Connector Plate.png |300px|alt=Installing the Wall Mount Connector Plate]]</div>
  </li>

  <li>
    <p>Repeat '''Step 2~5''' for the remaining two Upper Wall Mount Brackets.</p>
    <div class="res-img">[[File:LDM231-251 Installing Other Wall Mount Brackets.png |400px|alt=Installing other Wall Mount Brackets]]</div>    
  </li>

  <li>Install the Lower Wall Mount Brackets in the same manner as the Upper Wall Mount Brackets. The distance between the Upper and Lower Wall Mount Brackets is 1440 mm.
  </li>

  <li>
    <p>After installing both Upper and Lower Wall Mount Brackets, the installation wall should look like:<p>

===Installing the Cabinets===
<ol>
  <li>
    <p>Place the Upper Cabinet section "D-1" and Lower Cabinet section "D-2" on stable furniture that can safely support the two Cabinet sections.</p>
{{Note|
:*One Cabinet is separated into two sections. Each section weighs around 18.6 kg (41 lb). 
:*You can identify Cabinet sections by the labels on the package.
:*The arrow marks on each Cabinet section should be pointing up.[[File:LDM231-251 One Cabinet.png|250px|center|alt=One Cabinet block]]}}
  </li>

  <li>
    <p>Attach the Upper and Lower Cabinet sections with the two provided screws (M8 x 20 mm).</p>  
    <div class="res-img">[[File:LDM231-251 Installing Upper and Lower Cabinet Sections.png|500px|alt=Installing Upper and Lower Cabinet sections]]</div>

  <li>
    <p>Repeat '''Step 1~2''' for Cabinet "E".</p>  
  </li>
  
  <li>
    <p>Install the assembled Cabinet "E" on the right side of Cabinet "D" with the provided screws (M8 x 20 mm).</p>  
    <div class="res-img">[[File:LDM231-251 Installing Cabinets-6.png|450px|alt=Installing the second Cabinet]]</div> 
{{Note|There are 12 screws between each Cabinet.[[File:LDM231-251 Installing Two Cabinets.png|250px|center|alt=Installing two Cabinets together]]}}
  </li>

  <li>
    <p>Check for unevenness of the Cabinets by rubbing the cross section between each Cabinet. If the cross section is not aligned, loosen the M8 screws slightly and tap the Cabinets until the cross section is flat.</p>
    <div class="res-img">[[File:LDM231-251 Installing Cabinets-7.png|300px|alt=the cross sections between each Cabinet]]</div>

==Separate Installation==
When the System Control Box is installed apart from the Cabinets, this installation type shares the same Wall Mount Brackets as the Standard Installation. However, you will need to pre-drill additional holes for the System Control Box.
===Wall Mounting===
Eight Wall Mount Brackets are used for mounting the screen to the wall.
<ol>
  <li>
    <p>Ensure the wall area is an appropriate installation site.</p>

{{Note|
:*You can also install the Upper Wall Mount Brackets, hang the screen, and then install the Lower Wall Mount Brackets for a more precise fit.
:*Adjustment in floor clearance and ceiling height should be made according to the actual installation site.
}}
  </li>

  <li>
    <p>Using the illustration as shown below as a guide, mark at least eight mounting holes and pre-drill them.</p>
    <div class="res-img">[[File:LDM231-251 Hole Spacing Guide.png |500px|alt=Mounting Hole Spacing for the Wall Mount Brackets]]</div>
