• Lamp 2

Use Lamp 2 for projection. The system switches to Lamp 1 if Lamp 2 is abnormal in activation.

• Single: Use the single-lamp mode for the projection. The lamp is not speciﬁed in this mode, the projector

selects the lamp that has the least operation hours automatically whenever it is turned on.

Note

1. In the Lamp 1 or Lamp 2 mode, the projector will switch to another lamp when the set lamp becomes abnormal. The corres-

ponding LED indicator of the lamp will flash simultaneously for seconds and light up. 2. When the lamp mode is set to Single, the

setting will become valid upon turn-on of the projector next time. 3. Quick switch of the lamp mode may affect the life of the lamp.

The projector will disable the lamp mode function (highlighted) every time when a switch is conducted till the switch of the lamp

mode is completed. The lamp mode options will not be available before the switch of the lamp mode is completed.

High Altitude

Use this function to control the cooling fan of the projector. You can set it to OFF or ON, the default setting is

OFF.

keystone, the projector can operate normally when this function is set to OFF. The projector detects ambient

temperature by default to regulate the cooling fan speed. When the temperature rises, the cooling fan speeds

up (with higher noise) to exhaust the internal heat energy out of the projector and ensure its normal oper-

ation. However, the projector may turn off automatically if it is used in an environment at excessively high

temperature or in an area at a high altitude. In this case, you can enable this function by setting it to ON and

have the cooling fan operate at a higher speed to control the internal temperature of the projector.
