1.Timely response to emergencies
The Ledman installation engineer first found that the roof pipe was leaking. The first time, the on-site construction personnel blocked the water leakage, and informed the project leader, the supervisor and the school principal to wait for the emergency. Through coordination with multiple parties, first clean up the water on the ground.
2.Methodically investigate the dangerous situation and share the worries for the customers.
Due to the large surface area of the screen, whether the display screen is damaged or not, the customer is deeply worried. Once the screen is damaged, it will not only cause huge economic losses to the customer, but also delay the overall project progress and cannot guarantee the delivery on schedule.
The installation engineer immediately removed the module for inspection at the site. After investigation, the supervisor, the school and the construction unit were informed that there was no obvious water mark inside the cabinet after the “washing”, and the water stain on the surface of the screen was wiped clean with a rag.
After the screen is normally lit, the customer is full of praise for the super waterproof performance of the COB HD display.
3.Quick commissioning to ensure delivery requirements
