	· If using the Android version: At the top of this screen, confirm that the network name shown is “Liahona”. Below the network name, you will see a blue box that says “Channel” followed by a number. This indicates the wireless channel that you are currently connected to. If the channel number is a number from 1-11, you are not connected correctly to the network for the purposes of this test. Move your phone closer to one of your building’s APs, turn off the WiFi radio on your device and turn it back on. Do this until the channel number is no longer between 1 and 11. '''Please note that this information will not be shown in this way when using the Apple version of the WiFiman app, so this step can be skipped on Apple devices.'''		* If using the Android version: At the top of this screen, confirm that the network name shown is “Liahona”.

	· Before starting a scan, move to a location in the building that you can later recognize once the map is created. Going to the end of a hallway at a specific corner of the building or going to the edge of one of the building’s foyers may be good places to start. Taking note of where you start your scan can help you orient yourself on the heatmap once the scan is complete. Also, a scan should ideally be done when the building is not occupied as the presence of other people can interfere with the scan.		* Before starting a scan, move to a location in the building that you can later recognize once the map is created.

			* Once you are in your starting position, press the “Create New Scan” button to start your map. You will now walk through all the spaces in your building while the app detects and records the WiFi signal strength as you move. WiFiman uses your device’s camera, compass and gyroscope sensors to establish its position in space and generate the heatmap based on the measurements it records. These sensors must remain unobstructed for the duration of the scan. They also need time and patience to ensure they do not become disoriented. Please follow these recommendations as you scan your building:

When scanning individual rooms, you should enter and leave the room through the same door. Walking around the perimeter of the room will make it more recognizable on the finished heatmap.

	· At the top of this screen, confirm that the network name shown is “Liahona”. Below the network name, you will see a blue box that says “Channel” followed by a number. This indicates the wireless channel that you are currently connected to. If the channel number is a number from 1-11, you are not connected correctly to the network for the purposes of this test. Move your phone closer to one of your building’s APs, turn off the WiFi radio on your device and turn it back on. Do this until the channel number is no longer between 1 and 11.		· At the top of this screen, confirm that the network name shown is “Liahona”.

	In this example, WiFiman became disoriented while moving around the Relief Society Room, which caused half of the map to be twisted out of alignment. If this occurs, you will need to redo your scan.		In this example, WiFiman became disoriented while moving around the Relief Society Room, which caused half of the map to be twisted out of alignment.
