WARNING
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT OPEN THE PANEL ACCESSIBLE DOORS WHEN
POWER IS ON.
Always ensure that the unit is properly earthed and power connections correctly made
This equipment must be supplied from a power system providing a PROTECTIVE EARTH connection and
having a neutral connection, which can be reliably identified
The power outlet supplying power to the unit should be close to the unit and easily accessible
Always remember to close and lock the panel access doors after servicing and before resuming the power
supply
Ensure whole system power off before connect or disconnect the net cable
Always remember to dry the panel fully before packing
Store in a dry and airy place
Suggest using below method to cleaning the Intelligent Modules (IM): Using electrostatic-proof soft-brush to
clean the IM per month to keep the LEDs clean. Clean with solvents is not allowed.
The picture in the manual just for reference, the actual subject to shipment product.
Electrostatic discharge may harm the surface of the LED units. To prevent such damage, you should
discharge static electricity from your body before you contact with the LED units.
The product must be installed in an environment out of human reach. If a person touches the product, its
performance may deteriorate. If the product needs to be installed in a place where human contact with the
product is likely, a separate measure to prevent people from touching it needs to be taken.
[Caution to prevent damage to the LED from static] Do not touch the product without anti-static gloves.

2.2 Intelligent Modules (IM)
The front face of the A136-15-OB LED display is fitted with 72 light emitting diode (LED) dot LED modules known as
Intelligent Modules. Each intelligent module is fitted with 28880 LEDs* plus associated drive electronics. Electrical
connections (low voltage power, and digital data) are made to the rear of each intelligent module, from inside of the
enclosure.
Figures 2 and 3 are showing the front and rear views of an A136-15-OB intelligent module.
*Remark: each intelligent module contains 160x180 pixels (row x column) and each pixel is composed by 3 in 1 LEDs, so there
are totally 28800 LEDs fitted on the front face of an intelligent module.

3. Installation Guidelines
The A136-15-OB LED display, each intelligent module is equipped with 4 pcs guide pin, are fixed with magnetic
structure and jointed together both vertically and horizontally, so that they can form one surface of screen-
configuration.
The A136-15-OB LED display is designed to be mounted on the stand (sold separately) or on the wall. When
installing, it is important to ensure that the entire screen is correctly aligned, both vertically and horizontally.

Step6. Put down the intelligent module and tool together carefully onto an EPE (or other soft pad).
Step7. Push the lock toward inside and pull the right handle toward outside and lift the tool up carefully.
Mount Intelligent Module
Step1. Take out a spare intelligent module and locate the intelligent module to case,please pay attention to the arrow
direction on the back side of it.
Step2.Flatten the intelligent module.
Note: When mounting an intelligent module back, pay more attention to the guide pin which
is located in corners to mount it smoothly.
9. We recommend that all the intelligent modules are installed to the corresponding position on case, or the screen
will show color difference. Also, there is a panel serial number at the left bottom of case which match to the one
on the back side of intelligent modules and spare intelligent modules.
