What shall I do if the presenter does not work at all?
This is probably because:
The presenter is not switched on.
- To switch the presenter on, press the dongle inwards until it clicks. Then take the dongle out.
Note: Removing the dongle by only pulling it out of the presenter does not switch the presenter on. You really have to use the press-to-release method described above.
The presenter runs out of battery.
- Press the laser button to check the battery. Replace the battery if it is empty.
