2.4.1.9. Restore Defaults Menu
Default demo settings are restored.
2.4.1.10. Error States
In case of critical error the demo goes to error state. Power-on-reset can reset the demo from error state. LED4 is
continuously on in error state.

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.

If the wrong selection is set or the selected data rate number is not supported (e.g., no custom data rate is
stored), the default data rate (high precision GFSK) will be selected.

All LEDs blink once
Ready state
i. Blinks all LEDs once if selection is OK.
ii. Blinks LED4 and beeps buzzer once if parameter had to be set to default because of an
unsupported selection.
