Safety Precautions - HIMS Braille Sense U2 User Manual

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
