3.4. Network communication cable
A communication cable is required to transfer data from the display device to an external device.
LAN cables must be STP type 1000Base-TX Cat5e or better (Cat6A recommended). If cable
needs more than 30m long between SPU and DPU, it is recommended to use outdoor fiber optic
cable to maintain a network speed and stability. (Refer to the Appendix B for more information)
3.5. Precautionary item
1) Use only single phase 100-240VAC local power supply.
2) DO NOT overhaul or modify.
3) DO NOT work on during electrical storm.
4) DO NOT scratch, cut, forcedly bend, pull, twist, bundle, or damage the power cable. Also do
not put heavy items on top or around.
5) DO NOT touch inside equipment with a wet hand.
6) Connect ground conductor for equipment protection and electric shock prevention from
lightning induction and ground leakage.
7) Cleaning instructions: Use dry soft cloth to wipe the surface. If it is difficult to remove stains use
the cloth soak with a neutral detergent to clean surfaces. Please DO NOT use an alcohol or an
organic solvent (e.g., thinner) to clean surfaces.
