Safety Precautions

For your safety and protection of the Braille Sense U2 QWERTY, 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 QWERTY 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 On the underside 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 QWERTY has already done this for you. The battery may not be fully charged when it is shipped. Before you use the Braille Sense U2 QWERTY, you should ensure the battery is fully charged. 
3. When you use the Braille Sense U2 QWERTY with the battery for the first time, the battery status may not be displayed accurately. To avoid this, leave the Braille Sense U2 QWERTY connected to the AC adapter for about six hours with the unit turned on. If you want to use the Braille Sense U2 QWERTY 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 the battery is replaced by an incorrect type. Please make certain to use only battery packs produced specifically for the Braille Sense U2 QWERTY by HIMS. Please dispose of used batteries according to the instructions.
5. When you are using the Braille Sense U2 QWERTY 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 QWERTY 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.
