Operation Settings Quick Cooling Selecting On enables the function and projector cooling time will be shortened from a normal 90-second duration to approximately 15 seconds. Blank Timer Sets the image blank time when there is no action taken on the blank screen, once elapsed the image will return to the screen. If the preset time spans are not suitable for your need, select Disable. No matter Blank Timer is activated or not, you can press most of the keys on the projector or remote control to restore the picture. Reminder Message Sets the reminder messages on or off. High Altitude Mode We recommend you use the High Altitude Mode when your environment is between 1500 m -3000 m above sea level, and ambient temperature is between 0°C-30°C. Operation under "High Altitude Mode" may cause a higher decibel operating noise level because of increased fan speed necessary to improve overall system cooling and performance. If you use this projector under other extreme conditions excluding the above, it may display auto shut-down symptoms, which is designed to protect your projector from over-heating. In cases like this, you should switch to High Altitude mode to solve these symptoms. However, this is not to state that this projector can operate under any and all harsh or extreme conditions. Security Settings Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient temperature is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under such a condition. Power On/Off Settings • Direct Power On: Allows the projector to turn on automatically once the power is fed through the power cord. • Signal Power On: Sets whether to turn the projector directly on without pressing POWER or ON when the projector is in standby mode and detects a VGA signal or a HDMI signal with 5V power. • Auto Power Off: Allows the projector to turn off automatically if no input signal is detected after a set period of time to prevent unnecessary waste of lamp life. • Power Off Timer: Sets the auto-shutdown timer. Instant Restart Allows you to restart the projector immediately within 90 seconds after turning it off. See Utilizing the password function on page 76. Operation (under non-Launcher source) 91
