How is the Beam Trainer system used

Switching it on

The Beam Trainer system is switched on by pressing the POWER/MODE button for about half a second.
As the LED light goes on, pressure to it should be discontinued.

Switching it of

The Beam Trainer system is switched off by pressing the POWER/MODE button for about three seconds.
After that the LED light turns on which means that the system will eventually turn off, after we release
the button.

Selecting a channel

The Beam trainer device QF11A-T needs radio wave connection with the frequency of 915MHz. Four
channels are available. After the device is switched on, the first channel is chosen. One LED blink denotes
the first channel selected. If a change of channel is needed, pressing the "POWER/MODE" button is
necessary to choose the next one which is noticed by the appropriate number of LED blinks.
Advice: channels should be changed only in two cases:

When the communication between devices is not working (another device of unknown origins
uses the channel)

If we use more testing setups in the same range, it can be helpful to separate them by different
channels. Please note, however that the device from another setting cannot affect our
measurements even if it uses the same channel, because each Beam Trainer QF11A-T device has
its unique serial number to identify with.
Important: when we change the channel on one of the devices, we must do the same on all others
within the same setup.
