Using the virtual wall unit (FC8820)
Placing the batteries in the virtual wall unit
The virtual wall unit operates on four AA batteries.
1 Push the two release tabs at the bottom of the back cover (1)
and slide the back cover upwards and off the virtual wall unit (2).
2 Take four new AA batteries from the pack and insert them into the
battery compartment of the virtual wall unit.
Note: Make sure the + and - poles of the batteries point in the right direction.
3 Slide the back cover onto the virtual wall unit again.
Positioning the virtual wall unit to stop the robot
You can use the virtual wall unit to prevent the robot from entering a
room or area that you want to keep it out of.
1 Place the unit at a spot beyond which you do not want the robot to
go, e.g near an open door to a room that is off-limits to the robot or
at the top of a staircase.
2 Switch on the virtual wall unit with the on/off slide on top of
the unit.
3 Switch on the robot for a normal cleaning run.
4 When the robot comes too close to the virtual wall unit, the light
on the virtual wall unit starts flashing and the virtual wall unit emits
a beam of infrared light. This beam of infrared light makes the robot
change its course and move away from the virtual wall unit.
