HIMS International Corporation H432B Manuel D’Utilisation

For your safety from the Braille Sense U2, please read safety 
precautions carefully. 

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 

separate from the unit to avoid damage. The battery may not be 
fully charged when it is shipped. Before you use the Braille Sense 
U2, you should make sure the battery is fully charged. When you 
use the Braille Sense U2 for the first time, you may need to open 
the package, take the battery, and insert it into the battery slot at 
the rear panel of the unit. It is possible that the dealer or 
distributor from whom you purchased the Braille Sense U2 from 
has already done this for you. 

3.  When you use the Braille Sense U2 with the battery for the first 

time, the battery status may not be displayed accurately. In order 
to avoid this, connect the Braille Sense U2 to the AC adapter for 
about six hours with turn on. If you want to use the Braille Sense 
U2 immediately after opening the box, you will need to connect 
the AC adapter to the unit for more than six hours to fully charge 
the battery. 

4.    If you want or need to take the battery out of the unit, turn the 

power off, and then take the battery out of the unit. Before putting 
the battery back 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 dispose of used batteries according to the 
instructions.

5.  When you are using the Braille Sense U2 on battery power only 

(without the AC adapter), the status of the remaining battery 
power will be announced when the battery power is low. When
