2.Physical laser is on but weak.

1）Physical lasers can only be used on projection screens or walls, they cannot be used on LED/LCD screens. It is normal for the laser to appear weak when used on such screens.

2）A wireless presenter that complies with the Laser Safety Regulations will also have a weak laser when used in an outdoor environment with sufficient lighting, which is also normal.

Other than the above 2 cases, the laser module may be damaged, please contact the seller.

IV.Function of page forward and backward

1.Cannot turn pages and laser does not light up.

Check that the batteries are charged; check that the power switch of the wireless presenter is turned on.

Please try again after Pairing according to the instruction on below official link: http://www.lygmkjx.com/faqcn/501-cn.html.

If the wireless presenter still can't turn the pages after successful pairing, you can switch among the following three modes (some products have four modes)by long-pressing the ‘＜’ and ‘＞’ buttons for 3 seconds, depending on the type of presentation software you are using, such as PowerPoint, Keynote, Prezi, or others.

If the problem remains unresolved, contact the seller.

3.Cannot turn the pages, the operating system prompts ‘Unrecognized USB device’.

1）Please try changing the USB port and computer first to rule out the computer problem.

2）Please run the Norwii Presenter software and connect to the USB receiver, check the color of the USB icon at the bottom left corner of the software, a red icon indicates that the USB receiver is faulty, please contact the seller.

V.Long press ‘＜’ or ‘＞’ cannot full screen or black screen

Please change the input method to English input mode and try again. In Chinese input mode, long pressing the '＞' key will display a series of 'bbbbbbbbbbb'.

Tip: Some customers want to disable the long press function of ‘＜’ and ‘＞’ key to prevent misuse. You can run Norwii Presenter software and click ‘Customize’ tab, set the long press function of ‘＜’ and ‘＞’ key to 'Null'.

VI.Mouse Cursor

1.Mouse cursor drift.

The following two cases of cursor drift require calibration.

1）The wireless presenter does not move, but the cursor moves by itself in a certain direction up to the edge of the screen.

2）When the product is moved horizontally or vertically, the cursor does not move horizontally or vertically but moves diagonally in a certain direction.

2.Calibration method.

Place the wireless presenter on a flat, stable surface. Turn off the power of the wireless presenter, long press the ‘＞’ key and turn on the power, then release the ‘＞’ key, the indicator LED will start flashing. Keep the wireless presenter stable, the indicator light will stop flashing to indicate that the calibration is complete.

Calibration can be repeated, if not successful, try again.

3.In full screen, the mouse pointer stays shown/hidden.

In PowerPoint full screen /slide show state, click the right mouse button, in the ‘Pointer Options’ - ‘Arrow Options’ to modify the settings.

VII.Annotate function

1.This product has two types of annotate function, see the following figure.

1）As shown in the above figure, the first is to use Norwii Presenter to annotate. You can use annotation key to start annotation, use Eraser key to end annotation. Ink cannot be saved.As shown in the above figure, the

2）second is to use mouse to annotate. This way is limited to PowerPoint and WPS software. When PowerPoint or WPS slide shows in full screen, you can press and hold the annotation key to annotate and release annotation key to end annotation. Ink can be saved to file.

You can use this method with PowerPoint 2007 and higher, in which the software itself has annotation feature. Early versions of Office, WPS and macOS systems do not support the second way.

2.Display a string of 'eeeeeee' when deleting an annotation.

Please change your computer's input method to English mode.

VIII.Not charging

To charge, use a charging cable with USB-A on one end and USB-C on the other end. Some presenters do not support charging with USB-C charging cables at both ends.

IX.Short control distance

Communication between the wireless presenter and the USB Receiver is via 2.4GHz wireless signals, which may affect the control distance if there is an obstruction between them. If there are strong Wi-Fi, Bluetooth or other 2.4GHz wireless signals in the environment, it may also affect the control distance. It is normal for the actual control distance to be shorter than the advertised distance due to different usage environments, but if the control distance is very short, e.g. less than 5 meters, please contact the seller.
