Operating the cleaner
Using Guard (virtual door) mode
The VIRTUAL GUARD forms an invisible door that the
robotic vacuum cleaner cannot cross until current room
is completly cleaned. The VIRTUAL GUARD opens the
invisible door when cleaning the of room is complete.
1. Select Guard (virtual door) mode using the Mode/
Power button.
- The mode lamp fl ashes green.
2. Install the VIRTUAL GUARD at the entrance of the
room to be cleaned.
- Install the VIRTUAL GUARD so that the distance
detection sensor can form an invisible barrier that
the robotic vacuum cleaner cannot cross.
• When not using the VIRTUAL GUARD, turn the power off.
(When not using the robotic vacuum cleaner for
NOTE
long periods of time, separate the batteries to avoid
discharging them.)
• If the Mode/Power button does not work, it indicates
that the batteries have worn out. In this case, replace the
batteries. (Specifi cations: Type D (LR20) alkaline batteries )
• You can additionally purchase a VIRTUAL GUARD from

About the IrDA sensor.
• The infrared signal transmission may
CAUTION
not be smooth in locations exposed to
halogen lamps or in outdoor locations.
• Robotic vacuum cleaner uses 3 types of
infrared devices and a device may not
work in front of another device with a
higher priority.
• When controlling the robotic vacuum cleaner with the remote control, the robotic vacuum
cleaner may cross the virtual fence of the VIRTUAL GUARD or run against an obstacle,
because the remote control signal has a higher priority than the VIRTUAL GUARD signal.
• When using the robotic vacuum cleaner in a small location or at a close distance,
it may malfunction due to interference of the infrared signals.
• Install the VIRTUAL GUARD away from the charger as auto charging may be
interrupted if the VIRTUAL GUARD is near the charger.
• If more than one robotic vacuum is used simultaneously, they may malfunction
due to interference of the infrared signals.

A guard (virtual door) is formed. A guard (virtual door) is formed.
✽ Since an invisible barrier is formed
to prevent the robotic vacuum
cleaner from running against the
VIRTUAL GUARD, installing the
VIRTUAL GUARD within 30 cm of
the outside walls is recommended.
