When you purchase a Hamster robot, the robot and USB dongle are not paired. The first time you use it, you must pair the robot and USB dongle.

1. Plug the USB dongle into the USB port of the PC. It is normal if the Bluetooth connection indicator of the USB dongle blinks slowly in blue.
   Where is the Bluetooth connection indicator on the USB dongle?
   
2. Turn the power switch up to turn on the power.
   
3. Bring the Hamster robot close to the USB dongle. (Within 15cm between robot and USB dongle) It is normal if a beep sounds and the Bluetooth connection indicator of the Hamster robot and the USB dongle is steady blue or blinking rapidly.
   Where is the Bluetooth connection indicator of the Hamster robot?
   

• This process is called pairing.
• After pairing, one robot and one USB dongle pair with each other.
• Pairing is required only once when connecting the robot and USB dongle for the first time.
• Since the USB dongle remembers the paired robot, it does not matter if the PC is changed.
• Since the robot and the USB dongle are paired only when they are close to each other (within 15cm), there is no problem to pair or use many robots and many USB dongles at the same time in the classroom.
• Pairing or connecting between a robot and a USB dongle is not related to software because it is performed by hardware.
• The reason for plugging the USB dongle into the USB port of the PC is to supply power to the USB dongle.

If they are already paired, you do not need to pair them again, but plug the USB dongle into the USB port of the PC and turn on the power of the robot.

1. Plug the USB dongle into the USB port of the PC. It is normal if the Bluetooth connection indicator of the USB dongle blinks slowly in blue.
2. Turn the power switch up to turn on the power. It is normal if a beep sounds and the Bluetooth connection indicator of the Hamster robot and the USB dongle is steady blue or blinking rapidly.

• You do not need to pair the robot and the USB dongle again, if they are already paired.
• When the robot is turned on, it is connected to the USB dongle even if they are far apart. (Within 15 meters)
• Since the USB dongle finds and connects only the paired robot, there is no problem if you use a lot of robots simultaneously in the classroom.

1. Turn off the robot that was previously paired.
2. Plug the USB dongle into the USB port of the PC. It is normal if the Bluetooth connection indicator of the USB dongle blinks slowly in blue.
3. Turn the power switch up to turn on the power and bring it close to the USB dongle. (Within 15cm between robot and USB dongle) It is normal if a beep sounds and the Bluetooth connection indicator of the Hamster robot and the USB dongle is steady blue or blinking rapidly.

• The USB dongle remembers only the last pair of robots.
• You can not pair with a new robot while the USB dongle is connected to another robot. In this case, the robot connected to the USB dongle must be turned off and disconnected before pairing the new robot.
