If the indicator blinks when the projector is started, the device is started. You can proceed with the next step only when the indicator does not blink. When the machine is turned on, it has a warm-up process, which takes about 10 seconds. During this, must not think projector has not worked and repeatedly press start key, the impact current that frequent boot produces can affect the service life of bulb. At the same time, it is strictly prohibited to shake, move the projector under the boot state, and forcibly power off to prevent accessories from burning and blasting.

When using a laptop, it is necessary to link the power cord to prevent the power supply from running out midway, and cause the projector bulb to burn out. After the boot, we should pay attention to constantly switch the screen to protect the projector bulb, otherwise it will make the LCD board or DMD board internal local overheating, causing permanent damage.
