1, switching sequence:
開屏時：先開機，后開屏。關屏時：先關屏，后關機
Tail: the first boot after the tail. Off screen: first off screen, after the shutdown

(first off the computer does not turn off the display, will cause the screen to appear high highlights, led burning lamp, the consequences are serious. )
2、開關屏時間隔時間要大于5分鐘。
2, switch screen time interval is greater than 5 minutes.
3、計算機進入工程控制軟件后，方可開屏通電。
3, the computer control software into the project, can spread electricity.
4、避免在全白屏幕狀態下開屏，因為此時系統的沖擊電流最大。
4, avoid the peacock white screen in full screen mode, because the impact of current at the maximum.
5、避免在失控狀態下開屏，因為此時系統的沖擊電流最大。
5, to avoid out of control under the tail, because the impact of current at the maximum.
A計算機沒有進入控制軟件等程序;
A computer does not enter the control software and other procedures;
B計算機未通電;
B computer not energized;
C控制部分電源未打開。
C control part of the power is not open.
6、環境溫度過高或散熱條件不好時，LED照明應注意不要長時間開屏。
HERSHEY'S 6, the ambient temperature is too high or the cooling conditions, LED lighting should be careful not to long time tail.

7, electronic display part, appears very bright, should pay attention to timely and off screen, in this state should not be long tail.
8、經常出現顯示屏的電源開關跳閘，應及時檢查屏體或更換電源開關。
8, often appear on the screen of the power switch trip, should be timely check the screen or replace the power switch.
9、定期檢查掛接處的牢固情況。如有松動現象，注意及時調整，重新加固或更新吊件。
9, regularly check the solid condition of the hang joint. If there is a loose phenomenon, pay attention to timely adjustment, re reinforcement or renewal of hanging pieces.
10、根據大屏幕顯示屏屏體、控制部分所處環境情況，避免蟲咬，必要時應放置防鼠藥。
10, according to the large screen display screen, the control part of the environmental conditions, avoid insect bites, when necessary, should be placed on anti poison.
