=== Scanning LLA markers ===
Under certain circumstances, users might want to specify a manual location instead of using the current location detected by their devices. This can be achieved by scanning an LLA marker in the POI view.
=== Switching on/off LLA only mode ===

Sometimes, it is necessary to temporarily turn on [[Location_Manager#Possible_positioning_modes|LLA only mode]]. For example, once the users enter a building where GPS or other locating systems are not reliable enough, they could, however, use the on-site LLA markers to precisely locate themselves. Afterwards, the LLA only mode can be turned off so that the users can continue to use the locating systems outside the building.
{{UBIK}} provides an LLA only mode button in the POI view for scenarios like this.
When LLA only mode is inactive, there should be a toggle button in the POI view. A single click on it would switch {{UBIK}} from the current [[Location_Manager#Possible_positioning_modes|positioning mode]] to LLA only mode; And another from LLA only mode to the previous mode.
When LLA only mode is active, {{UBIK}} ignores all other location updates except the ones from [[#Scanning LLA markers|scanning LLA markers]].
{{Hint|During LLA only mode, {{UBIK}} stops most of its location services. However, services such as GPS require a long initializing time before they can be used. Considering the fact that LLA only mode is switched on and off for a short period of time, {{UBIK}} keeps such services on "standby" so that the mode switching is smooth and instantaneous.}}
