# Wireless Tools Restrictions

When all WLAN (3) or Bluetooth slots (6) are filled, additional wireless tools paired with the controller will replace existing paired tools. There are a few rules governing this replacement.

In the case of WLAN, one of the previously paired tools will be replaced at random.

In the case of Bluetooth, offline tools will be replaced first, followed by online tools. Tools linked to a Virtual Station will never be replaced. When pairing an additional Bluetooth-equipped tool to a controller that already has six wireless Bluetiooth tools linked to Virtual Stations, make sure to remove one of the paired tools from one of the Virtual Stations before pairing the additional tool. The tool disconnected from the Virtual Station will then be replaced by the new tool.
