1. Battery voltage check

Battery voltage

More than 2.5V

Normal charge is indicated when the power switch is turned on and the Power LED turns on for 2 seconds.

If the Power LED blinks for 5 times after the power is turned on, the battery voltage is low.

Look

Less than 2.5V

- If the Power LED blinks for 3 times after the power is turned on, please push Power button again.

- When the voltage of Microprocessor IC under 2V, the power doesn't turn on.

- The IR receiving distance is shortened when the power-supply voltage decreases.

2. Shutter operation check

Check shutter open/close operation by changing 2D/3D select switch on the user menu.

The liquid crystal shutter open/close timing is controlled by receiving IR signals from the TV, which provide 3D expression of the images.

1. Change the switch to 3D and 2D, repeatedly.

2. Glass color is changed to dark and bright by detecting a Shutter On/Off signal from TV if they are working propely.
