Safety Precautions

For your safety and protection of the Braille Sense U2, please read and abide by the following safety precautions.
1. The input voltage of the AC adapter is 100V - 240V, and the output is DC 5V / 2A.
2. When the Braille Sense U2 is shipped, the battery may be packaged separate from the unit to avoid damage. When you use the Braille Sense U2 for the first time, you may need to open the package, remove the battery, and insert it into the battery slot at the rear panel of the unit. (See section 1, introduction, for more details on inserting the battery.) It is possible that the dealer or distributor from whom you purchased the Braille Sense U2 has already done this for you. The battery may not be fully charged when it is shipped. Before you use the Braille Sense U2, you should ensure the battery is fully charged. 
3. When you use the Braille Sense U2 with the battery for the first time, the battery status may not be displayed accurately. To avoid this, leave the Braille Sense U2 connected to the AC adapter for about six hours with the unit turned on. If you want to use the Braille Sense U2 immediately, you may use it while it is charging.
4.  If you want or need to remove the battery from the unit, power the unit off, and then remove the battery. If the unit is connected to AC power, before re-inserting the battery in to the unit, make certain that the power is off.
There is a risk of explosion if battery is replaced by an incorrect type. Please make certain to use only battery packs produced specifically for the Braille Sense U2 by HIMS. Please dispose of used batteries according to the instructions.
5. When you are using the Braille Sense U2 on battery power, the status of the remaining battery power is announced when the battery charge is low. When the battery's charge falls below 15 percent, connect the AC adapter to the unit for recharging. If the remaining battery charge drops to five percent, and the unit is not connected to the AC adapter, the Braille Sense U2 shuts down one minute after the announcement of the battery's status. The amount of battery life per charge varies depending on the options you have set and the number and type of tasks you are running.
6. Your Braille Sense U2 needs to be handled with care. The Braille Sense U2 is a very delicate machine. Please handle the unit in a proper, careful manner. The Braille Sense U2 is very sensitive to dust. Make sure to keep the Braille Sense U2 away from dusty environments.
7. The Braille cells are very sensitive, intricate parts. If the Braille cells are not working properly due to the presence of dust or for any other reason, please contact our repair center, or the dealer from whom you purchased the Braille Sense U2 for support.
8. You should register your Braille Sense U2 in order to ensure further maintenance, service, and upgrade information. Please visit www.hims-inc.com, to register your information. If you have any trouble when registering your information, please contact the dealer from whom you purchased your Braille Sense U2 for help.
9. Do not take apart the Braille Sense U2 yourself. Do not have anyone else who is not authorized by HIMS take apart the Braille Sense U2. If an unqualified person disassembles the unit, serious damage may occur to the Braille Sense U2. If an unauthorized person disassembles the Braille Sense U2, the unit is excluded from any free maintenance, and the warranty becomes void. If any liquid or external force damages the unit, it may also be excluded from free maintenance, even if the damage occurs during the warranty period.
10. Do not leave your Braille Sense U2 in closed or high temperature environments such as inside a car on a hot summer day, as the battery attached to the Braille Sense U2 may be damaged or catch fire. Please do not let your Braille Sense U2 remain in such environments for long periods of time.
