4. Troubleshooting
Q1. Why does my presenter doesn’t work?
A1. Check that the receiver is firmly attached to the USB port on your computer and
Windows built-in drivers are properly installed.
Make sure you have established a communication link between the presenter
and its receiver. Refer to “Using the Keys” section for instructions.
Q2. I have re-established the link between the presenter and its receiver. But some
of the keys still do not work.
A2. The keys’ functions depend on the operation mode. For example, if you find the
Page Up / Page Down keys don’t work, it may because that the presenter is in
the Windows media player mode.
Q3. Is there any method that I can identify the presenter’s current operation mode?
A3. No. If you find the keys don’t work as expected, use the Mode key to switch the
operation mode.
Q4. Why does the laser point function doesn’t work?
A4. The laser point function is not activated by default. You should activate it before
you can use it. Refer to the “Activate / De-Activate Laser Point Function”
section for details.
Also, if the presenter is not operated for more than 10 minutes, the presenter
goes into sleeping mode and de-activates the laser point function. To wake up
the presenter, just press any key on the device. To use the laser light function,
you need to activate it again.
