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 a '''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(PositioningMode not set 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 often switched on and off for a short period of time, {{UBIK}} keeps such services on "standby" for a while so that the mode switching is smooth and instantaneous.}}
