How to charge?
 You can charge a Hamster robot by the charger for a smart phone. You need to connect the
micro USB plug to the charge socket of a Hamster robot.
 You can also charge a Hamster robot by a USB cable. You need to connect the micro USB
plug of the cable to the charge socket of a Hamster robot and the opposite plug of the cable
to the USB port (socket) of a computer.
 The charge indicator is continuously on with red during charging and will be off when the
charging is completed.
 Fully charged, you can use the Hamster robot for about 1 hour. (30 minutes for charging,
sustained operation: 1 hour in average, waiting (non-operation): up to 12 hours)
 It is better to charge after turning off the robot.

Bluetooth connection indicator
 Blink slowly in blue
Waiting connection
The Bluetooth connection indicator is blinking slowly in blue when the power of the robot is
turned on.
 Continuously on with blue
Connected
The Bluetooth connection indicator is continuously on with blue if the robot is connected to
a PC or a smart phone/tablet.
 Blink quickly in blue
Data transmission
The Bluetooth connection indicator is blinking quickly in blue while the robot receives data
from a PC or a smart phone/tablet.
 Blink slowly and intermittently in dark blue (or the charge indicator blinks in red)
Battery low
The Bluetooth connection indicator is blinking slowly and intermittently in dark blue or the
charge indicator is blinking in red if the battery of the robot is very low. In this case, you
have to charge the robot.
The Bluetooth connection indicator blinks slowly and intermittently in dark blue for the
Hamster robot produced in the beginning, while for the Hamster robot produced after
November 20th, 2015, the charge indicator blinks in red.
 Turned off
The power of a robot is turned off.
