Ch 1 / Ch 2 -> Walktest menu item

The Walktest menu item allows the performance of a reception test.

Once you have set up and installed all of the receivers and transmitters for your event, we recommend performing a walk test. This lets you check whether sufficient reception strength is available throughout the entire area used.

Start the walktest function in this menu item and then walk the entire area with one transmitter. The results of the walk test give you information about the reception quality.

Opening the Walktest menu item

In the menu, navigate to the Walktest menu item for the desired channel.
Press the jog dial to open the menu.
The following view is displayed:

To start the reception test:

Press the jog dial.
Walk the entire area on which you want to operate the system with the transmitter.
The following values are recorded on the display:
- RF: Reception from antenna in dBm
- LQI: Connection quality as a %, see Meaning of the Link Quality Indicator
- AF: Transmitter audio frequency in dBFS

To end the reception test:

Press the Jog-Dial to finish the walk test when you are ready.
