Frequently Asked Questions

If the blue LED on the wireless presenter starts to flash slowly, it means

the power is low and the battery needs to be recharged.

If there is no laser beam emitted when you click the Laser key; or, the LED

indicator does not work when you click other keys; it means your battery runs

out, please charge it immediately. Excessive discharge will severely shorten

the useful life of lithium battery.

When you charge your wireless presenter by a computer, please make

sure the computer is switched on.

Red LED on means it being charged; Red LED off means the charging

completed.

Firstly you need to turn on the power. Secondly you can check whether

the wireless presenter is in low power or out of power. If the LED flash slowly, it

means the power is low and the battery needs to be replaced. If all the other

buttons can work, only the laser pointer cannot work, the laser diode may need

replacement.

4) When the mini USB receiver plugs into the PC USB, the laptop does not

detect the device, why?

Please try another USB port or another PC.

5) Laser beam becomes darker and darker, what should I do?

Dark laser beam is usually caused by the low battery. Please recharge your

battery. After charging, if the laser beam is still just a dark red spot, it means

the laser module is aging. You can contact us for post-sale service.

6) Shortcut keys do not work or work incorrectly, what should I do?

This case may be caused by the change of shortcut keys in operating

system or applications (e.g. PowerPoint). Please check your shortcut keys

setting in your system or applications, or make your data backup and then

reinstall the operating system or applications.
