2.5. How to Use the Range Test Demo

Put battery into the two RFstick devices and switch them on. Both devices will start in ready state. Select the

required demo settings or start the measurements with the default or the automatically reloaded settings.

Switch one of the devices into RX and the other into TX state. Check if transmitter sends packets and receiver

answers as well.

The range test could be performed inside a building if indoor propagation is tested. However it is advised to

perform the test outside the building, line-of-sight to get the best possible range result. If PER>1% reset the PER

on the transmitter and try to walk further in the area. It is usual that propagation conditions get better if the user

goes further from a possibly shadowed area.
