Samsung VCR8874T3B/XET manual Using Guard virtual door mode Option, About the IrDA sensor

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.

[Infrared Signal Priority]

Operating the cleaner

Using Guard (virtual door) mode (OPTION)

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.

03 OPERATING THE CLEANER

Distance Detection Sensor

• When not using the VIRTUAL GUARD, turn the power off.

NOTE

(When not using the robotic vacuum cleaner for 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 Samsung Electronics customer care Co., Ltd.

About the IrDA sensor.

CAUTION • The infrared signal transmission may

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	Remote Control	VIRTUAL GUARD	Charger
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.
